What size solar panel would I need to run a rotating fan?
That you could run that fan straight from the panel. A 2 Watt panel is about the right dimension. It will begin spinning at cut down vigour output however not acquire the rated speeds unless peak vigor from the panel. The perspective should be satisfactory.
The Guardian asks: Are we really going to let ourselves be duped into this solar panel rip-off?
I've often thought about crooks bypassing meters myself. But surely to get paid for the electricity you've stolen and sold to the grid would require an "Import/Export meter". At present obviously we only have an "Import" meter to enable our bill for usage of electricity to be measured. Surely there's only one cable? The same cable surely imports on demand and exports when the householder's electricity production exceeds demand, thus the "excess" is fed to the grid via the "Export" meter? It's not April 1st is it?

How can you have solar panel home?
Not easy to convert it into AC power because it produces DC power that is different than from wall outlet power source and its voltage is very low, like 0.5V per cell. Must need first to charge a very big battery bank, and then convert the battery power into AC power with a converter before able to power a fridge. Solar penal contains many small solar cells, they convert sun light ( the only free light source) into electricity directly with a very low efficiency like 5%. Mount them with a strong frame on top of roof facing to the open sky to catch the bright sun light, under shadow would not work well or produce no electricity. A VERY EXPENSIVE SYSTEM AND REQUIRE TAKE CARE OF IT DAILY, AVERAGE LIFE IS 5 YEARS.
If someone shined a flashlight at a solar panel, would it generate electricity?
It may generate electricity. But it would not generate as much power as your flashlight would use. Your flashlight produces light. It also produces heat
Would a solar panel that generates 50 kW of power charge a battery to 500 kWh in (about) 10 hours? (I'm assuming there would be some losses, but I wanted to see if that was correct for most cases)
You are theoretically correct, except that it is too much to expect charging at topmost power of 50 KW non-stop for 10 hours, starting from discharged condition. You will never get sun for this long period and that too at this level.Sunlight will be available for maximum 5-6 hours a day, and intensity depends on season, weather and other conditions. Intensity keeps varying over a day, over a season for the same time.So you will have to charge it at a higher rate, or be content with the charging you get in a day, and wait for few days for complete charging
I have a 30 watt solar panel that puts out 1.8 amps. What size battery should I get?
regular car battery will work but you will need more than one . may be 30 or more depending how much eletcricity you need when there is no sun or not enough sun. It depends on a number of factors do you have A.C. electric oven stove electric dryer ect.
An appropriate voltage regulator / limiter for a 5V solar panel for USB charging?
My first reaction is to put the two panels in series, then use a off the shelf buck regulator chip. If the two panels can not even put out 6 V or so in series (3 V per panel), then there is so little power available that it does not matter if the output is just shut off
How to convert a 10-Watt solar panel into 3v & 3 amp?
I saw somewhere an answer to a question that seemed to apply quite usefully to your question. I am posting it here with slight modification. Note that this is not my work - just seems mainly useful.Comments in [square brackets] are mine.[These are all good points worth noting that many people miss]To get 9W out of a 10W panel you need bright mid-day sun, the panel must be clean AND pointed towards the Sun and 90% SMPS efficient Buck Regulator that utilizes the 17.3V max power level of the array.[worth noting]Not all SMPS will do this as the switching current can be much higher than the average current thus drop your PV Array well below Vmax power, so more Power management design is required, such as a 17.5V battery design to regulate the input voltage. If you do not , you will be lucky to get 5W.[Here is a useful TI web bench simulation that somebody has set up that matches your need.]You also want an Econo mode for cloudy days for more efficiency.The TPS54526 is one good solution.
will this solar panel power this fan through dc current?
Yes,you will need a good storage battery to carry it through the night
I want to make a solar panel for 240 volts, help me out please?
If you are in Malaysia, I am not sure why you need a heater, except maybe a water heater. For that, use a solar heater directly. For the electricity, the most cost-effective way to do it is to stay connected to the grid, and offset your bill with solar. That way, you do not need to oversize the solar for contingencies. There will be compromise in your lifestyle, everything that plugs into the wall today will still plug into the wall and work fine
is 12v 800w solar panel enogh tu run a 12 cubic refrigerator?
A 12 cubic foot fridge operates on 110 volt power, not on 12 Volts, you will need a generator to power a fridge
What would a 60 watt solar panel power? How many watts for a small home?
You can run a 60 watt light bulb when the sun is shining. Or your can charge a battery and then run the 60 watt light bulb at night. It theory if you had 8 hours of sun you would be able to run the bulb for 8 hours off of battery. In reality because of losses you will not get 8 hours of bulb running time
what all can a 200 watt solar panel power up?
I am going to assume you have a 200 watt continuous wattage converter on your deep cycle batteries. Overall there is not a definite answer as much as a recommendation by doing research of items around the house that you may want to run. The best way to do some figuring is to take the wattage requirements of devices around the house. The most common CFL lamp is 13 watts 120 volts. You can extend the charge life by using 12 volt LED lighting, which would bypass the inverter (always a good idea). Ditto on a fan - a typical modern 20" box fan draws 50-100 watts depending on speed. A laptop computer can draw over 100 watts alone when under a full load, but taper off when not needed. The list could go for miles. A Kill-A-Watt wattage meter is a must have for checking items around the house for their actual current draw. Many ratings are maximum ratings, not the actual real-world normal draw. Also look into more and more direct 12 volt items. Then you can bypass the inverter, and that is a plus as the inverter is not totally efficient.
Does anybody know if there are any courses for solar panel installation, and/or what trades you need for this?
What you ought to recognize will depend on WHAT sort of installations you are going to be operating with. In regular, for business you wish to have fundamental mechanics and wiring. For house, you may additionally want a few carpentry, roofing, preserving structural integrity, plumbing, and so on. In side it additionally will depend on what sort of sun installations you are doing, (vigour, air warmers, water warmers, and so on.)
Is this how much this solar panel collects an hour?
it collects 135 watts an hour ( think of it as gallons in a pail) at 17 volts ( the pressure in the pipe filling the bucket ).....yes all you tech savy people I know its not quite that simple...... so when that panel is operating at peak efficiency ( which depending on how far north you live is anywhere from 2 to 6 hours a day) you could charge a 12v battery at 8 amps....of course at 17 volts you would fry a 12v battery really quickly; you need to buy an regulator as well.......or if you were running the panel to an inverter you could power two 65 watt light bulbs.
I have a few solar panel stick in the ground night lights that beep in the evening but don't give light. Why do they beep?
My guess is, they only beep in the daylight hours, because their internal battery is shorted or otherwise non-functional, they have no or insufficient voltage to operate at night, and cannot charge in the daytime.And maybe they screwed up when assembling, and those few were put together with "make an annoying beep when voltage is present" parts, rather than functional "solar-recharged night light" parts
anyone Arco solar panel ASI 16-2000 watts ?
These are around 25 years old The following link is for some test done on these old modules that found them to be about 30W. (Actual wattage will be dependent upon incoming sunlight) Starts on page 5
would wiring a solar panel and grid tie inverter to the house wiring save electricity?
NO, it just changes the source
Can I charge my 12v deep cycle battery with any size solar panel?
Yes I use a 50 watt panel to charge my boat batteries
does sunlight in winter have the same amount of power for a solar panel?
Yes it will. The reason is that the panel, being pointed directly at the sun, will have the same surface area regardless of the season. The earth on the other hand is tilted at about 23 degrees, so during the winter the sunlight is spread over a greater area than in the summer, so it does not warm the air as much and hence, colder weather. By maintaining an angle perpendicular to the sun at all times, the sunlight is never spread out. Although you will have to adjust it throughout the year to maintain that angle, as the earth will 'tilt' beneath it.
Could a solar panel, essentially power itself?
No, because energy is lost through dissipation and through the conversion process. With mirrors you might be able to reduce this effect.
Can someone explain this microcontroller ADC interface (for reading solar panel voltage)?
What is the role of the pnp transistor network?It's a differential voltage to current converter followed by a load (R34 and R35). The voltage between P and P- sets a voltage across R31. This (minus 0.7 volts) sets a voltage across R33 and that causes a current to flow out of the collector (largely irrespective of what load the collector has). Given the values of R33, R34 and R35, whatever voltage is set across R33 appears across R35 but, reduced by 3:1. Importantly, this voltage is ground referenced making it suitable for the ADC to make sense of. So there is level shifting involved
