This is a cold call from Enver Solar who tried to scam me into buying solar with fake promises about non existant rebates.  They also tried to sell me new windows!  Really....you go from selling windows to solar in a second?  You obviously can't be very good at either in my opinion.   Do not do business with these crooks and do not answer their calls.  Very pushy and aggressive people who don't want to take no for an answer.
