My electric isn't that high, usually averages between $150-180. It would cost me $30k to install solar panels on the ground. I've spoken to others with them on their roofs. Heard horror stories when needing new asphalt shingles, they can't get anyone to remove the solar panels, and then reinstall them back. Others claim the panels cause roof leaks after a few years. Others have told me some chinese made panels loose their ability to produce the same amount of electricity as new once they get dirty, requiring you to go up on the roof to clean them.My electric bill has been $300 plus a month. With the panels paid off it will drop to about $130 on a bad month.
