Q:Where to buy cheap solar panels?
Grimcho..I'm going to give you a secret that no-one I know of has ever spoken of..Call Your local railroad maintenance yard and/or your local oil production company..I know your probably in another part of the world where this will not apply but here its like this.. BNSF changes out every 2-5 years their 00w 24v panels...they still have a good 5years of lifetime..Oil companies change them out on their well sites every 2 years 2x 60w 24v (actually they are 2 +2vdc grids series) now if your in Italy sorry this didn't work but if your in New Mexico ..they are in Santa FE...also they have way good batteries that are wet cell and run about 600$ each that they just dump many times on the guy for asking..try it....From the E....
Q:What is the cost of Solar Panels?
That okorder.com/
Q:solar panel design question?
Because we and the trees are trying to solve a different problem. We want electricity, a tree wants light (and some heat) for photosynthesis. In getting the electricity we use Silicon for solar panels. (Sometimes Gallium Arsenide). And we exploit the same thing in Silicon that allows them to be computer chips. The fact that they conduct differently when voltage is applied. But for a solar panel that is done essentially in reverse. We GET a voltage difference (electricity) from shoving energy through it. Look up junction bias on google or yahoo for explanation. But the DESIGN problem is: You have to couple these panels together the right way - according to their bias. You can't string them up willy nilly. There is a pattern. And when one breaks in this pattern. (I mean when the actual panel cracks, which they do easily as they are brittle). It can change the overall bias. This can make even be worse than if it was removed, it can actually fight against the working ones. The efficiency is there in arranging them like a tree, but the practicality of maintenance would be daunting.
Q:Solar panel for your home?
it all depends on how much electricity you use for heating/cooling and cooking.......if you just need lights, TVs etc then you could get away with about $5-8,000 US for a system depending on how far north you live.....to go completely off the grid is near $25,000 by the time batteries and inverters and all of that is figured in....
Q:Does anyone know a company that will make custom solar panels?
Make okorder.com
Q:Can I install solar panel straight to battery on my truck?
If you were going to do that it would have to be the right size solar panel and you would need a solar battery charger so it doesn't fry your car battery
Q:Please differentiate b/w mono & poly crystalline silicon solar panels.?
how much does these pannels way and which are the most efficient?
Q:How much is the average solar panel?
You are way out of your depth if your report for science class is supposed to be knowledgable. First of all, Solar panels alone will NOT be enough to charge the battery bank, which you don't even mention in your quesiton. Secondly, the only way to have a usable 2 VDC system is to use a wind generator to keep the batteries charged to capacity and, as a plus, they will work at night. A 65 Watt ARCO Solar Panel is about $300 and you need to figure your power by the Wattage Rading for the particular panels . You also need to add in the cost of a 2VDC to 0VAC invertor, monitoring panels etc.... AND... just how big is the ROOF of the house you are planning to use.? This is an area of involved study and it's a bit more than what you are imagining for your high school science class report.
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:Charging batteries with a solar panel?
can I use a 2volt .5 amp solar panel on a 2 volt battery in a boat that i use for trolling motor and if I can can I leave it hooked up when using the trolling motor ? Plus how long would it take to charge a half drain battery with this panel??
