Sun Solar Panels
SOLAR PANELS (sun enerjy)?
I have a question about solar panels. What are the benefits of this system if I installed in my home. for example i know it produces electricity but does it do anything else? How many panel would you guys think I would need for 2000 sq ft. do you know if it produces hot water?
Thanks for your help
First, solar panels come in two basic types – photovoltaics, which produce electricity (the black cells you normally think of), and solar thermal, which heats water (or some other fluid). It’s one or the other, you could install both if you want that. Solar thermal is cost effective today, depending on how you currently heat your water. (The hot water could also be used to create electricity, like in a steam turbine, generally done in larger power plants).
Photovoltaics are more expensive, but coming down in price every day. To know how many panels you need, you first have to determine how many kWH your house uses, and do you want to be completely off the grid (which would also require large batteries), or just reduce your electric bill.
