I would start flossing once or twice a day (at least until it gets better) and brushing, also find a good rinse. Crest Pro Health is a really good one that keep infection away, it's alcohol free so it does not burn to much in your mouth and within a few days you should see a differece in your gums. Good luck and if it does not clear up soon I would really try to see a dentist or add and extra cleaning in throughout your day.Are dwarves and dark elves the same?The issue with figuring the answer to this is to know that Norse mythology now has been convoluted by old Christianity. This was done to make people who follow the Norse mythology to be easier to lead into Christianity. As Helheim was made after Christianity helped change it. The original realms were as soThis was the original list of the realms but as stated it was later changed to make it easier to convert Nordics to Christianity. As it was easy to link Ragnarok meaning the end of gods with Christianity. As the world will be born again from the fires of Surtur. Christians of old used this to convert many Vikings or Nordics into their faith as they could use this for how Adam and Eve started as only 2 humans are to survive Ragnarok. Another thing that contributed to this was that Hel daughter of Loki whom watched over the dead was doing this in the realm of Niflheim. But in order to link the bible and Norse mythology more. They changed a little in order to add the realm Hel where the dead are that are not taken to Valhalla or . when originally they went to Niflheim as Hel resided there. others who died in battle or not of age or sickness went to Valhalla located in Asgard or Folkvang in Vanaheim. So other then the changes do to different religions leaking in these were the original nine realms. So in turn the answer is no Dwarves and Dark Elves are not the same. they were mixed together to be able to add in the realm of Hel.

Yes, the panels charge batteries that will allow it to work in the dark, until the charge runs out.. .Yes. They put out light in the dark of night and then they charge up when the Sun comes up.. .Solar lights collect solar photon energy during the day through their solar panel. This energy is converted into electricity and stored in the rechargeable (usually Ni-Cad) batteries. A photocell sensor detects whether there is sunlight available or not and acts to switch the lights on based on this. The electricity stored in the battery is regulated by a control board and, at night, the charged batteries provide power for the LED light. Once daylight returns, the panels repeat the process of charge.IBM Thinkpad T20, I want to use some car batteries... how would I do this?If you want longevity but not portability, please plug in the power cable to the power socket. You can run the notebook until the power to your home is cut or your notebook dies. But to answer your question directly, I do not think it's a good idea.How would i power multiple guitar food pedals without batteries?Yes. there's pedalboards and boxes which provide power for multiple pedalsHow to use car batteries for breadboard projects?THOSE SMALL LEAD ACID BATTERIES FROM YOUR LIST CAN PROVIDE AS HIGH AS 30A CURRENT WHILE ACCIDENCELY SHORT BOTH TERMINALS. BURNING THE BREADBOARD WITH SUCH POWER SOURCE AS FAST AS IN SECONDS. UNLESS, AS A SAFE WAY TO USE THEM, INSERTING A 2A FUSE TO LIMIT ITS CURRENT BEFORE LINKING TO BREADBOARD POWER INPUT. THIS WAY, FUSE BLOWS AND CUT OFF 12V POWER IF YOU MAKE MISTAKE ON BREADBORAD CIRCUIT. 12V CAN BE CHANGED INTO 9V POWER SOURCE BY USING A SIMPLE VOLTAGE REGULATOR IC CALLED LM7809.How the batteries in the vehicle recharged during moving?Your vehicle has an alternator, this is similar to a generator.

You should do a watched full charge. Anyway the charge controller should tell you if is gone. If it is not, carry on and be more careful next time. If they got hot then you just damaged them and you should replace themHow long will these batteries last if the radio has a resistance of 200 ohms?I came up with the same formula as Bill but with 133.3 minutes rather than hours: 240 / .03 = 8000 8000s / 60s/m = 133.3minutes = 2.22 hours Interestingly, the article below (quoting another article!) states: "The amount of charge that travels through a typical alkaline AA battery is about 5 kC = 5000 C = 1400 mAh. After that charge has flowed, the battery must be discarded or recharged." If that were true, we would have 4 * 5000C / .03C/s = 6.67E5 s = 6.67E5s / 3.6E3s/h = 185 hours = 7.7 days. .Solar controller with BJT transistor and PIC24 microcontroller to charge 3.6V NiMH batteriestl,dr: In your case, you do not seem to need charge control at all, and it is more complicated than you seem to sink because of various reasons. Just put a 1N4001 between the solar cell and the battery.The NiMH battery is a quite low impedance, pulling as much current from the solar cell as available at the cell voltage. During charging, it is likely around 1. 4V/cell. This is an output voltage of 4. 2 Volts, so in bright sunlight, you likely exceed the 170mA quoted for the maximum power point, expect something like 200-220mA, which is below C/10 of the cells. I have no idea how you want to do NiMH charging control at widely varying charging currents that never exceed C/10 (no -deltaU, no dT/T seems applicable, but let's ignore that).First thing to notice: Your circuit will not work as drawn. You drew a NPN transistor. It needs a voltage at the base that exceeds the emitter voltage (by around 0.6V) to make it conductive, but the uC has no access to provided the needed 4.8V (battery voltage 0.6V). You need an PNP transistor instead. In that case, you need to to provide current from the base terminal to a more negative sink. Also, you would connect the emitter to the solar cell in that case. Note that to turn off the transistor, you need the base voltage to go up to 0.5V below the unloaded solar cell voltage, this is around 8V. Start with the desired collector current (220mA maximum cell output) and take a look into the transistor data sheet. Let's choose a BC327 for it's higher current rating compared to the typical 100mA transistors. Take a look at figure 4 (Saturation region) if you want to have low losses on the transistor, which seems like a good idea now (but see later). They have curves for 100mA and 300mA collector current. As we do not have a lot of energy to waste, choosing a base current at the low end of the neary flat end of the saturation voltage curve is a good idea, which yields something around 4mA if you interpolate between the 100mA and the 300mA curve. To turn in the transistor, at 4.4V solar cell voltage, 200mV transistor drop, and 4. 2V battery voltage, you need to sink 4mA at 4.4V-0.6V (emitter-base voltage). To turn it off, base must rise to 8V (see above). This means, you need a pull-up resistor between base and emitter, providing the turn-off voltage from the cell instead of the uC and a diode (1N4148 will do) to protect the uC from that high voltage. So the circuit looks like this: PNP with emitter to solar cell, and collector to the battery. A resistor connecting emitter with base (the value does not matter much, and something around 100k will provide enough pull-off effect without disturbing the circuit while the transistor is on), a diode and a resistor in series to the uC. The uC needs to sink 4mA to turn the transistor on. This results in an output voltage of 0. 4V. So the resistor has to sink 4mA while having 0.4V above ground on the uC end and 3.8V above ground on the diode end. 4mA at 3.4V is 850 ohms. So 900 Ohms in your circuit does not seem off that much.You will not be happy at all with that circuit for different reasons, though: Constantly sinking 4mA takes too much of the charging current (getting 220mA outdoor on a bright sunny summer day is one thing, on cloudy days, being inside, expect something like 10mA maximum), and you are wasting 4mA of that just to turn that transistor on. Furthermore, when it gets dark, the solar cells draw power due to their leakage current and discharge the battery by operating the transistor in reverse mode (collector acts as emitter, base current is provided by the solar cells and the 100k resistor meant as pull-up, and the emitter acts as collector). Common wisdow is you need to protect against that, for example by putting a diode between the collector and the battery. You will lose voltage there, though. Another possiblity would be a "secondary pull-up" that will pull the base up, even if the emitter supply (the solar cell) fails to provide power, by connecting a resistor from collector to the base terminal. This resistor has to be low enough to pull the base up against the 100k that pulls it down, so go for something like 20k there. Of course adding all these resistors does not make the thing more efficient.Actually, your charging current is very low compared to cell capacity. As estimated above, you only get to C/12 on extraordinary good conditions, you the charging current can safely be considered as "trickle charging" unless you put the device into the beam of a bright headlight 24/7. You do not need any charge control. You just need to prevent discharge through cell leakage, and this can be povided by a single diode between solar cell and battery

In the previous read, we've talked about the "Quest for an Energy-Efficient Future" and the quest is still on. You must be wondering, How on earth. LED solar lights are related to the dark future anyhow? Eventually LED Solar Lights, would-be savior, from the darkness.However, we are experiencing the consequences of our past activities in the future. On the basis, we can clearly sense the future without any brightness, neither in the day and most definitely not in the night.Lights play's a major role in our lives. We would not pay much attention to them is another thing. We all are aware of that, we have very limited natural sources available, and to retain those sources is next to impossible. The number of consumers is in masses, where the sources are limited and about to extinct, however some of them already extinct.Most of all, we are in the middle of the energy crisis! Where everybody is asking for a potential solution for the Energy Crisis. Unexpectedly (Hong Kong scientists) came up with a solution to stabilize the Energy Crisis. A Drop of Rain Can Power 100 LED Bulbs"Triboelectricity" a Teflon Coated Surface to generate charge from the raindrops. Scientist of (Hong Kong) university has used this phenomenon and invent a device to yield energy,by infringing the water-droplets by engineering that constitute a "polytetrafluoroethylene" (Teflon) film on an- "indium tin oxide substrate plus an aluminum electrode" allows a high energy conversion."Triboelectricity" means "friction electricity" eventually an old concept comes from a Greek tribe. Static electricity would be the best example of Triboelectricity. Basically,It's an Old concept improvised and executed more efficiently than ever before.As scientists say the previous version was not very effective, where the material did not allow to transfer much of electrical charge. Where it's next to nothing!But, In the recent research. We've come up with exceptional & unexpected results. Where they are working on a concept & assimilate the field-effect transistor (used to control the electric field to control the flow of current). Performed several tests and come up with an explanation, drop off a 100 microliters dropped from a height of 15 cm, can generate 140V of energy, simultaneously this much volt is enough to light up 100-LEDs Bulbs.These types of inventions can stabilize the Energy Crisis. Where LED Solar Lights ensure the best alternative for a potential source of Light. A Potential Light Source- LED Solar LightIn the above section, we've talked about-How scientists putting their efforts to overcome the energy crisis. Simultaneously, we also need to put-up some steps to stabilize energy-crisis and search for a potential light source. So, there should be a Balance!Where LED Solar Lights is a medium of balance between a potential light source and energy-crisis. Solar Lights conceive their energy from the biggest energy source. The "SUN" is an utmost source of energy, which can last up to eternity.However, LED Solar lights consist of solar panels, which absorbs the sun rays through solar panels and stores them into a lithium battery. Where the sun rays turn into energy and channelize then into a lighting fixture.Those LED lighting fixtures are also designed to save 90% on energy bills. Which makes the fixture highly energy-efficient and saves up to 100% on energy bills. ConclusionLet's take a read back. What we talked about! Now, we have a potential solution for the energy crisis, on the other side, we have a probable source of brightness (Light). In this read, we've tried to put some light about our future, because, if some steps would not be put up then surely there would be an apocalypse of darkness. Where Solarmyplace comes up with a perception to illuminate the world with the light of the sun, even in the darkness.The Best Places to Install Solar Lights in Your Outdoor SpaceWhile lighting a path or walk is one of the most popular ways to add landscape lighting, avoid the temptation to evenly space lights on either side of the walk unless you are planning on landing planes in your front yard. Instead, create a more interesting look by staggering the spacing between the lights so they light different sections of the walk and integrate into the shrubs and flowers, creating a more natural look. Related: The Best Solar Flood Lights for Illuminating Outdoor Spaces If you've ever seen a movie that ends with the main character riding off into the sunset, then you may appreciate the aesthetic power of the silhouette. To create this striking look, place a spotlight between a landscaping feature, such as an ornamental tree and the light-colored facade of a home. The backlit tree's dark silhouette will stand out against the light background of the house. Since you will need to tuck the light between a structure and the landscaping feature, you will need a solar light kit that works well in this setting. This set of Aponu spotlights (available on Amazon) allows you to set the solar cell in a place that receives ample sunlight. Attach downlighting above the garage door or doors to create large pools of light on the driveway. This type of lighting effect can be created with lights such as these mountable spotlights (available on Amazon). The result is a nuanced look that's more subtle and less glaring than standard floodlights, while also providing functional lighting for nighttime visibility and security around the garage. Related: The Best Solar Gutter Lights for Outdoor Lighting You Never Knew You Needed Add the effect of a full moon to the landscaping on your property even on overcast nights by mounting spotlights above your property. Mount the lights to the trunks of medium- to large-sized trees and direct them to shine downward. The light will cast a glow on the lawn and walkway below, creating a moon glow effect. To add even more interest, hang the lights so that they shine through tree branches and other foliage, creating interesting shadows on the ground below. In addition to being an integral part of improving a home's nighttime curb appeal, outdoor lighting also is helpful for making your property safe for family and visitors at night. With this in mind, make the steps leading up to the front door safer by installing lights in the risers of each stair. Riser lights, such as this set of six (available on Amazon), create a soft glow that illuminates each tread to make traversing them at night safer.

Residents in Sri Raghavendra Nagar, near Thanneerpandal, close the gates of the park by 6 p.m. or 6.30 p.m. Though they like to keep it open for a while longer to let the children play and the elders walk another round, they can't because after sunset, safety becomes their first concern. This is despite the park having 15 lights."We, the residents, close the gates as soon as it gets dark because the park otherwise becomes a haven for anti-social elements and love-lorn couples who make the most of the darkness," laments A. Manoharan, a resident.There are 15 solar lights, but they hardly glow, barring the two that are at the south-eastern corner, closer to the house that abuts the park compound. The park has been dark for over a year-and-a-half after the Corporation developed and threw it open for the public two years ago after spending ₹ 63 lakh.The residents say anti-social elements scaled the compound to remove batteries from almost all the lights. They removed batteries from solar street lights as well.The darkness that fell as a result of the absence of lights also saw residents losing LPG cylinders, shoes, tyres and other items that were outside their houses.Former Councillor of the area, Ward 37, R. Vellingiri says that theft of batteries or accessories from solar lights is not unique to Sri Raghavendra Nagar alone. Residents from the nearby Telephone Colony, Jai Nagar, Thiyagi Kumaran Street, Thanneerpandal Sixth and Ninth Cross Streets have also complained.He notes the Coimbatore Corporation installing the solar street lights about four years ago after the then Singanallur MLA allocated a portion of his constituency development fund.Another issue concerning the solar lights that glow is that there is no proper maintenance. The residents say that the response they have received from those (contract companies) who had installed the lights has been that since the contract period for maintenance has ended, they would not be able to do much.The residents say that they have taken up the issue with their Ward engineer K. Maragatham asking for either installation of new batteries or lights to be powered from the Tangedco pole, but are yet to get a response.Ms. Maragatham could not be reached. A senior engineer of the Corporation's East Zone, who also supervises the area, says he has not received any such complaint from the residents.

The solar street light industry is growing exponentially with governments and organizations across the country and the globe offering incentives for solar installation. In the United States over 200 city mayors and city managers have committed to going 100% renewable by 2030. This growth is also being fueled by the increasing cost of traditional fossil fuels such as coal and natural gas power plants while renewables are going down. Renewables just surpassed fossil fuels for the first time ever last month. The government of India is planning to replace 35,000,000 street lights and almost 800,000,000 incandescent light bulbs with LED lights.Solar installers say cost per kw-hr is total charge/kw-hr from elect. co., but why would elect co agree to free use of their grid?The electric company is probably already charging you a connection fee and for the average household, that fee should not depend if you receive, send power, or how much power you use. (It is a little more complex then that) But that will not prevent them from trying to maximize profits while they still can.What improvements are needed to make pv Solar Installations better?Snow is a much more difficult problem.

Follow these tips to help make the right choice. There are a lot of solar companies out there. How do you choose? If you've read our Solar Panels Installation Manual from the start, you've made sure your is house energy efficient. You know more than you ever thought you would about the electric grid and the carbon footprint of solar panels versus fossil fuel power plants. You've done the math and figure that you are going to save thousands of dollars over the next two decades if you install solar. And you know how you are going to pay for it all. People get a little nervous about picking a solar installer because solar technology is still unfamiliar to a lot of people. Pretty much every homeowner has had to call a plumber at some point, but solar... that's something most people have never dealt with. How do make sure that you find the best contractor? In many ways, hiring a solar contractor is much the same as hiring a contractor to do any home project. Do not be intimidated by the technical nature of solar: if you do some due diligence and ask the right questions, you will be fine. This guide will help. Now what? How do you choose the best solar installer? Here's the tips that will help guide you to a good decision: Get in the right mindset We do not want to scare you or anything, but just be aware that buying solar is more complicated than. But it's also less work than remodeling your kitchen. So be prepared to do some work, but it's really not that bad. Just go into it with the right frame of mind. You are hiring a contractor. You will need to carefully review a contract and make a couple decisions, but not nearly as many decisions as if you were redoing your bathroom or kitchen. On the other hand, there are some companies out there that want make the home solar buying process a little bit like picking a flight or a hotel. We think that this is bad for the consumer for a number of reasons. First of all, this approach emphasizes price over other important considerations. It's okay to just go with cheapest option if you are , say, renting a car for the weekend - one company's Toyota Corolla is the same as a Corolla from any other. But solar panels are a product that are going to last you 25-30 years. Workers are going to come to your house and bolt a lot of equipment to your roof. It's a major purchase, so it's important to really understand the details of the product before you make such an important decision. Second, it encourages people to gloss over the important details of the equipment that you are buying. You might be prone to do this because solar can involve an intimidating number of technical aspects like watts, voltage, AC/DC, efficiency ratings, electric meters and monitoring systems. But, we promise, you do not need an engineering degree to figure this stuff out. So do not just make your decision on price. Consider the quality of the contractor and the contract details. Imagine that you want to do a big home renovation. You are going to make your dream kitchen! It's going to look just like the magazines. So you come up with a wish list of things that you want to have: shiny stainless appliances, granite countertops, a big island, wine fridge, that sort of thing. Oh, because you've got an older home where everything is a little bit crooked, you want the contractor to tear everything down to the studs and also install a new floor. Then you come across a website that promises to give you an accurate quote for all of this, just by filling out a form. No phone calls. No contractor will even come to your home to take a look around. Would you trust a quote like that? No, obviously not. If you are doing a kitchen remodel, a competent contractor needs to make a site visit so they can identify problem areas that will cause labor or materials costs to go up. Are there structural aspects to the space that will make the work more difficult? Is there electrical or plumbing work that needs to be upgraded? Is there a chance that your floor tiles have asbestos? All of these things would cause your estimate to go up, but none of them can be identified without a person coming to your home. Problems that cause solar costs to go up Solar panels and racking are heavy and last for decades, so a good contractor will need to evaluate the condition of your roof. Is the roofing material and decking in good condition? Do you have roof drainage issues that need to be addressed first? What is the size of your current electric service panel, and will it handle the additional load? Do wiring or circuit breakers need to be upgraded? Do you have landscaping that will cause shading problems after a few years' growth? Nobody on the internet can promise an accurate quote for your solar project if they do not come to your home to assess these kinds of things. A lot of people do not like sales calls. That's understandable. But for a project like a solar installation, you have to make an exception. In this case, you are going to get a phone call, and somebody is going to come to your house. This is a good thing. Get more than one quote Just like with your dream kitchen project, you need to get multiple quotes. This is not only to get a fair price, but also to compare the different materials, warranties, and credentials of the companies that you are evaluating. For example, one of the most important details of a solar installation is how the racking is secured to the roof and waterproofed. Ask the contractor exactly what methods and materials will be used. What is the fastening system, and what flashing and sealants are used to waterproof it? Or, maybe one installer insists that microinverters are the only way to go, while another contractor says that they would use string inverters for the project. In that sort of situation, you need to be prepared to ask each contractor why they selected one type of equipment over another. Never select a company only on price Everybody likes to save money, but do not save money on your solar photovoltaic system by simply going with the cheapest quote. There are real differences in equipment and installation quality . While it's very possible that your best installer will also be the cheapest, you can not know until you closely evalulate the details of the contract and materials. Conversely, going with the most expensive installer does not guarantee higher quality either. The biggest solar panels company installers, usually do not want to sell you a solar system. Instead, they tend to push you to rent one instead using financial products such as solar leases and power purchase agreements (PPAs). These financial products result in higher profits for them, and a lower financial return for you. There are a number of reasons why these financial products are often bad for consumers, but one of the key reasons is the inclusion of escalator clauses that automatically increase your cost of electricity every year, even if the utility company holds their prices flat. In addition, many of these large national installers have poor reviews and have even faced lawsuits by state governments. Prefer local companies that have been in business for a long time When you get a quote, we prefer local solar panels company that have been in business for a long time and have a strong presence in the community. Quite often, these are electrical companies that have decades of experience that have added solar installation to their portfolio. One reason is the obvious fact that a company does not stay in business for decades if they do lousy work. But the most important reason is that in order for a contractor to honor their labor warranty with you, they need to still be in business. The labor warranty, which is separate from a manufacturer's warranty, could be 5 to 10 years long, and even more with a few companies. With the explosive growth of residential solar across the country, a lot of new companies have sprung up overnight, especially in states like California. A company that has been in business for only a couple years might do great work, but running a company profitably for decades is a different skill than installing solar panels. Your best chance of having a company be around to service your system years from now is to pick one with a long track record. Be wary of brand new solar companies that have been in business for only a couple years. If you are independently doing research on solar installer companies, be selective about the review sites that you use. You will find sites, including ones that specialize in reviewing solar installers, that allow companies to appear as featured companies in their listings in exchange for a fee. This is a controversial practice , one we think that is misleading to the consumer. Which sites should you trust? Start with the BBB.org, which contains both reviews and a platform where consumers can file complaints with the Better Business Bureau, and companies are able to respond. Google Local Business is another site we think is reliable and does not offer paid placement. A few years ago, Yelp was accused of extortion , but the class action that followed was dismissed, and we think the company answered the controversy reasonably. Fake reviews are a different issue, and one that is more difficult to address. For this reason, we recommend you start with BBB, which uses human reviewers to check submissions. Check that your contractor is licensed The first thing to do is understand what type of license is required by solar installers in your state. The Interstate Renewable Energy Council maintains a website that lists what is required. Be aware that licensing for solar photovoltaic (PV) may differ from the requirements for solar thermal (which is used for hot water heating), so read carefully. Once you know what the requirements are, you can ask your contractor for their license so that you can look it up at your state's licensing board. California and Nevada, for example, make these databases searchable online, and also tell you how long the license has been active and whether the contractor is bonded. Check online to see what your state provides. Many companies list their license number right on their website, so you can do this check in just a few minutes. Never work with a company that is not properly licensed. There are many different components in a photovoltaic system, and each is covered by a different warranty from their manufacturer. It's crucial that the installer fully explain each one. The solar panels company should provide a warranty of the workmanship and components of the system, and cover the labor and replacement costs of any failing components. Photovoltaic panels have their own warranty, and often this is specified in two parts: one warranty covering materials and workmanship, and another warranty period covering their power output. Solar panels normally degrade over time, producing a little less power each year. (This degradation should be less than 1% per year.) The panel warranty will certify that it will continue to produce a given percentage of the original power output after a number of years. A 25 year power warranty is typical, and the product warranty should be at least 10 years and is sometimes long as 25. The inverter system is a critical part of the system, and will have its own warranty period. 10 to 25 years is typical. The racking system needs to hold up to potentially extreme weather for a couple decades. You want to make sure it has a strong warranty - at least 20 years. Are you getting batteries? It's a pricey component, so be sure you know what the warranty is. Meet your solar panels company contractor in person and ask a lot of questions We mentioned already that you should always have a face-to-face with your potential solar installer, right? Once you have an actual human person in front of you, that's the time to ask some important questions. Sometimes, the first person you meet with wo not be technical and can not answer all your questions on the spot. They might need to consult with other people on their team. That's okay. Just be sure that all your questions are clearly answered before you sign a contract. If you have not already checked that the installer has the proper licensing for your state, now is the time to do so. Also ask if their installers are NABCEP certified. What incentives are available? Use our calculator to find out about major incentives, but your solar installer may know about other local rebates. Be sure to understand if the owner receives the credits, or if the installer does and passes them onto the customer. Confirm if net metering is available to you, and make sure that you clearly understand how it works. (You can read our article What is net metering? for a primer. The estimate should list the price of individual components and labor: modules, inverters, racking, labor, electrical work, and other costs should be itemized. The contract should indicate exactly when payment is due, and what the payment schedule is (if any). You will receive a site plan that visually indicates the layout of the system components on your home, which includes the placement of the panels, inverters, disconnect switch, and meter. The installer will give you an electricity production estimate for the system in a year with average weather. Compare this with your average usage, and make sure that you are happy with the system output. Ask about labor and component warranties. Discuss the details of the solar panels, inverters, and racking system. Systems that are tied into the grid will require approval from the utility company, and possibly an inspection. Ask about the requirements and timeline of these. Your local code may require an engineering structural inspection before work begins, and an electrical inspection after work is completed. Ask what is required and when in the project timeline they occur. Your interconnected pv system will most likely require that your utility company install either a new bidirectional meter, or a second meter alongside your existing one. There may be a fee charged for this. Be sure to ask. Find out how you will monitor the system output. This will either be a display on the inverter, or a website or smartphone app. Ask if there is recommended system maintenance. If your roof needs repair, find out labor charges for removing and reinstalling the hardware. For component failures that happen after the installer's warranty, ask about the process for making a manufacturer warranty claim and having the component replaced. What are the different types of Uninterruptible Power Supply (UPS)?

My guess is not very often.Leaving an unused device “on” when leaving a room does not strike one as much as leaving water taps open.And so we waste a lot of energy and money, while a bit of care and attention could change a lot.I was convinced that at WWF we also need to do more about our energy impact, and walk the talk, and wanted to ignite this change.I worked over 10 years on energy policy for WWF, but I wanted some practice. Thanks to an MSc in Wales at CAT and solar work experience at Hassler Energia I acquired more hands-on, practical knowledge needed for this new challenge.Now I am looking for ways to make our offices more energy efficient, and to switch our energy supply to solar.Fifteen WWF offices across the world are already running on solar energy and I’ve seen the energy consumption drop drastically in all offices where we trained staff and made some technical changes, like replacing inefficient air conditioners. It works!But I couldn’t have done this without my colleagues.While they are concerned with other environmental issues in their day to day work, they are still enthusiastic to learn more about their impact and reduce their energy consumption.Switch off the plug — switch on the sun: Energy policy into practiceThis week it is WWF EPO’s turn!We have launched a Sustainable Energy Week, a chance for everyone to learn and share how to make energy changes that matter and to become more familiar with the solar installation on our roof and smappee.This cute device enables everybody to easily check at any time how much electricity we use and solar electricity we produce.Everyone in the office can do it, techie or not.When do you start? You might be surprised what a difference it makes.Jean-Philippe Denruyter is the manager for Applied Energy Solutions at WWF.

We also need a ladder to change a bulb 11' from the floor. It can take 20 minutes for 1 bulb! This is one reason that we have changed to the longer lasting (and more economical) low-energy bulbs.I would be delighted to have wall lights instead. Retro-fitting them would however be even less economically sound.Higher than average ceilings mean ladders to change the bulbs in ceiling fittings, and this extends the maintenance time and convenience for staff enormously. Even normal height ceilings mean that a chair is needed to swap a bulb out. Wall fittings are so much more convenient for both staff and customers, reducing the time taken to get light again!As Michael Forrest Jones says - anything other than a simple bulb swap requires the power to be cut to the whole circuit (which may be more than just a few rooms). This makes it very awkward to do emergency repairs after dark! -- Been there done that... Go with wall fittings that can be isolated in-room!In short:I have ceiling lights.I don't like them, as they are awkward for maintenance.Replacing them would be expensive and extremely difficult - basically a total rewire of the hotel lighting system.Design engineers are not stupid. they note the first 2 points!

Aside from making your yard look pretty, garden lighting serves several very important functional purposes as well. Here are a few of them to get you started. Lighting up your garden is not something that falls under a luxurious hobby that people only indulge in to impress the neighbors and friends. Garden lighting is basically a necessity more than a fashionable hobby or a passion. Imagine how inconvenient and boring it can get to organize a graduation party that you need to wind up before the sun goes down, only because you garden is not properly lit. Forget about parties, can you even stroll in your garden in a breezy summer night without lighting, or sip on a strong espresso to enjoy winters in a dark garden? Without lighting, your garden can look dreary and instead of giving respite, it will scare you. Garden lighting is immensely useful in a number of different ways. The first, being its use in allaying your fear to stroll in a dark, and gloomy garden. Then properly lit garden can encourage you to arrange different family and friends dinner parties and late-night get-togethers. This will eventually help you enjoy more with your near and dear ones and collect some memories along the way that you will love cherishing throughout your life. Other than this, the garden lighting can actually lease a new life to your dark and dreary garden, provided they are installed at the right locations. Creating a wonderful atmosphere in your garden does not imply that you need to install big bright bulbs all around. Bright and sharp lights can only serve to irritate your guests as well as neighbors, but will never provide a soothing atmosphere, a beautiful evening party demands. There are a number of different types and designs of garden lights available in the market. Before going for shopping, see if there are separate portions in your garden for sitting and cooking, etc or not. If yes, then you may need to provide extra lighting to that area rather than using the same dim lights as in the rest of the garden area. Afterwards, you should know that the most usual type of garden lighting is the down lighting that can be used anywhere in the garden. Nevertheless, if you have a pond or fountain in your garden as well, you should always think about installing the underwater or spotlights. In addition, you need to highlight the walkways and sidewalks, as it gives further definition to your garden.However, whatever type of lights you use, make sure they are soft and low-voltage lights. Prices of garden lighting vary widely; nevertheless, it is not expensive at all. To get an even more cheap deal , you can use solar lights. They are available in various attractive designs.
