1. Scientists? About Solar Energy (Electricity)?

its hard to exsplan so it just dose

2. a dollar per watt solar panels?

Most likely what you are seeing is the cost of the raw materials to produce the solar panels. The 4 to 5 dollar cost is the actual going rate for these. It is called mark up and cost of manufacturing. Also, if the really inexpensive ones are built in China, then you have a lot of shipping and handling costs added on

3. what is Solar installation training?

It is training on the proper installation and function of Solar energy equipment. This could include Thermal and Photovoltaic. Safety issues, electrical and plumbing, customer service, construction and government rules and regulations.

4. Best Camping Solar Panels

Camping solar panels are a great addition to a campsite if you would like to run some home comforts. Solar panel technology has made huge advancements in recent years, but be careful that your expectations are not a little too high. Do not expect to run a fridge or tent heater the whole day on a single solar panel, for that a camping generator is needed. Before we get to the best camping solar panels, its best to make sure you know what your needs are. If you just want to charge your iPod to have some music, there is no need to buy a 100W solar panel with a deep cycle battery. Solar (or photovoltaic) panels rely on the photoelectric effect to convert the suns rays into DC power. The solar panels are made out of silicone, a semiconductor (it shares similar properties of metals and that of insulators). Depending on your needs there will be an inverter in the circuit if you need to run AC appliances (120V/220V). How much power can a camping solar panel generate? This can be a tricky question and can get very technical. The amount of power a solar panel can generate depends on the amount of sunlight hours. Because an hour of sun in Alaska is different from an hour of sun in Arizona the industry have a measurement called Peak Sun Hour (PSH). Imagine it as the same as measuring rainfall and one PSH is the same as one "bucket" of sunlight. So for arguments sake, there are typically 5-6 PSH (or buckets of sunlight) in Arizona and only 1-2 PSH in Alaska. The solar industry uses a different method of rating the panels and will only roughly deliver about 70% of the power it says on the box. So a 100W panel will only deliver 70W of power. So multiply the panel rating with the PSH and you get your amount of power. For example a 100W panel in Arizona: Promise that's all the tech jargon over! So what does this mean? Here is a rough guide on the power needs of certain appliances (in watts): CD/DVD player - 30 Coffee grinder - 50 Computer (laptop) - 20 to 50 Computer (desktop) - 300 to 500 Computer printer (ink jet) - 40 to 70 Computer printer (laser) - 1000 Fans (230-volt) - 30 to 100 Food mixer - 350 to 45 Juicer - 35 Lights (compact fluro) - 5 to 18 Lights (LED) - 3 to 8 Macerator pump - 300 to 350 Microwave oven ('800-watts') - 1350* Portable radio - 5 to 15 Sewing machine - 75 to 100 Stereo - 50 to 60 TV (LED/LCD 16-20 inch) - 20 to 30 TV (LE/LCD 26-32 inch) - 100 to 130 VDC/DVD - 30 Washing machine (cold cycle) 225-300 Water pumps (12/24 volt) - 50 So after all said and done here is the top recommended camping solar panels. Almost all solar panel reviews will mention the Solar Joos Orange . The unit is built as tough as nails with a polycarbonate injection molded case. All the internal components are protected and it is also waterproof. The panels are very efficient and in test it has shown to charge an 4 from dead to full in an hour. This type of also allows the unit to generate power in the shade. Inside the case is a lithium-ion replaceable battery (20Wh/5400mAh), which will be charged in 12 hours in direct sunlight. I really like this unit, the only downfall is that it is not powerful enough for a laptop, but will charge anything else from an iPhone to IPad. Here is a video made by Joos that will explain its uses better: If you need to power a laptop but still need the solar panel to be ultra compact then the Goal Zero Nomad 13 is for you. Goal Zero specializes in solar energy and this is a great unit. The panels are in a folded, waterproof sleeve and can charge multiple units at the same time. You can either use a port or a 12v socket and it will charge any portable unit from to . Here is a look at it: If you are in need of more juice, but do not want massive panels outside your tent, the Unisolar 128 Watt camping solar panel is the one. This thin, flexible, panel generates 128w of solar power, but is still extremely light and portable. It's ideal if you want to flip it over the roof of the tent and it will still generate power in low light. Remember, you will have to buy an inverter or charge controller and battery for this system to work. So, as you can see, the best camping solar panels is not the biggest or most powerful, but rather the one that suits your needs the best.
