I have solar and lease, couldn't be more happier...
It cost me O out of pocket....
They say if your elect. bill is $150 / month or more, then solar is a good option.( you will need good credit to lease )
I went with Real Goods Solar, if you are interested give them a call, I reccomend them. Edison rates are always going up, with solar you are locked in.
Again if you bill is over $150 / then solar will reduce your energy cost. They look at your edison bill and see what you use for the entire year, then build you a system that will produce that amount of energy.
In my case I had them build a bigger system, then What i was using. And I am paying the same as before and having more energy to use. Hope this makes sense.
