efficiencey of a solar energy,system involve in solar energy & the cost involve in solar energy.?

Answer 1

Where I live many people have solar systems because no electricity. System includes solar panels, Batteries, Generator, and electronic controllers / chargers. Cost for an average house is about $20,000 - $30,000. System will most days provide for an average house electrical, but not heat or cooling unless you add an expensive ammonia air conditioning system. Must run generator on cloudy days and be careful with all electrical use.

If you have power and your electrical company allows, you can just have solar panels and controllers and supplement your system and cut you usage of electrical company. Can save money, but payback is very long.

Bottom line is solar works, but not cost-effective in most areas. Only cost-effective where sun shines most of the time. There are some good sites on the net that explain.

Answer 2

I built a large solar panel and put it in operation in the Ecuadorian jungle . There are several problems .First they need to be mounted very secure because there is a huge surface area . a 60 mph on that surface area will make them fly all over the jungle. second is isolation from each group so that is a hale stone breaks one it will not short out the hole panel and go up in smoke.They are expensive for the power they produce.
