Thanks...So we can form our own opinion...can you post some numbers as to your cost and your ROI or pay back estimate?
Yes, I hope to talk to some installers this week.
My first cut on this is it is not a good investment if the installation costs are more than about 20 percent of the total.
On a grid system, you don't have to have batteries or battery maintenance.
In Southern Arizona, I figure you get about the equivalent of six hours of full output per day, about 360 days a year, so we are nearly the best solar power place on earth.
I suspect the cost of "certified installers" will about offset the subsidies, and that might make it a worthwhile investment.
In the last 20 years, solar cell prices per watt have dropped about 70 percent. If they continue to do so, 20 years from now they will cost about 50 cents a watt. They would be a great investment at that price.
