My neighbor is getting solar panels installed by a company out of Houston. Apparently the company here is pretty rigid in there practice. He wanted a couple extra panels on a different side to charge the batter back up generator. A couple things are interesting, once the panels are installed you no longer pay the eclectic company you pay the solar panel place for 20 years at a locked in rate. The amount of panels depends on your average electricity use over a year. The last thing is that the back up generator/battery storage will is to run the a/c/heat in the event of a total power outage. the panels run everything else for a defined period, which i don't know what that is. I guess if you are going to live there for 20 years, then what happens to your insurance, then consider hail....i don't know what do you all think of the Solar installation?
