What is the least expensive and efficient residential solar energy system one can install?

Question

I just got an estimate of about $37,000, and that was after rebates and tax credits. And I would still have a sizeable PG&E bill. And would it save to install yourself?

Answer 1

Least expensive?   Probably replacing old windows with double pane ones that are larger and allow more light into your building.   If too much heat is the problem, still put in the windows, but add shades to block out the sun during the hottest times of the day.   There's more than one way to use the suns energy, and you might as well cut out the middleman.

Answer 2

how about a nice solar powered attic fan?

Answer 3

You know I bought 3 small security lights that run on light and they did not work so I am holding off on the big system. Plus PG&E is so expensive compaired to other companies.

Answer 4

Right now solar is NOT affordable.

Soon it will be.

NanoSolar is now starting to manufacture solar energy at 5 cents a kilowatt.

It will take years but when it comes out the price will drop dramatically.

Answer 5

One possible alternative is the link below. It is promoted by Ed Begley(Not sure of spelling). They install a well designed system at basically no up front cost. You then pay them for only the energy the system produces The rate you pay is exactly the same rate you are now paying, and they guarantee the same rate for like 20 years.

The idea is you pay no more than you do now, and when the electric company raises, you stay the same. You paid no up front money, but can start reducing your CO2 output now.
