Q:where to find used solar panels?
That's not a good idea. Solar panels wear out, and you probably won't know how worn out they are until you buy them and install them. Which is a little bit too late for most refunds. Your best bet if you're dead set on being foolish, is probably some place like craigslist.
Q:how to make your own solar panels?
if you want to make a photovoltaic panel from scratch, its extremely difficult, comparable probably to making integrated circuits. just buy a factory built panel solar-thermal is much easier
Q:how does a solar panel works?
Seriously, the best way to get an idea of what it takes is to call up a solar installer and get a free quote for your home. It costs you nothing, except your time. If there are no installers in your area, you may be in a bad location for solar.
Q:Solarcity free solar panels?
Remember, if it sounds to good to be true, it usually is .
Q:Solar Panel Circuit Question?
Do you know what is the rated Peak watts of the solar cell and the current needed to operate the relay. The power needed to operate the relay can be found from 9V * operating current, and that should be lower than the peak output power of the cell (perhaps significantly less as the peak power is produced only at high solar radiation levels. Another factor is whether the curves for the solar cell match the load. Typically the solar cells have a knee type diagram for the VI relationship, and that is why they need Maximum Power Point trackers to deliver a good power output.
Q:How do passive trackers work (for solar panels)?
It appears to be relying upon a phase change of liquid to gas to liquid to balance the system and return it to the east in the morning.

Q:how can i optimize power in a solar panel?
first place the panel so it is at right angles to the solar rays. Make sure none of the panel has any shade whatsoever. For best results use motor drives to keep it in that position as the sun moves across the sky. For overall maximum versus time, you need to be near the equator. Solar cells have a high internal resistance, so for maximum power transfer, you need a load of that same resistance. A good charge controller will use DC-DC converters to provide that load. .
