This is clearly some sort of scam, probably an attempt to get personal information. Someone calling himself "Nick" with an obvious Indian accent called this morning and claimed to have a deal for solar energy. He wanted to engage me in a sales-type dialogue but I declined; then he wanted my address, supposedly to send me info about their product/service, but I declined to give him that as well and asked for their web site instead. He said "www.usasolar.com" (a domain name that is currently for sale) and their phone number as "530.274.3671", a number belonging to California Solar Electric Company. I spoke with a representative of California Solar, who confirmed they are a local California company, do not install Solar in my state, and are not aware of the seller who called me. This is for sure some sort of scam, so you should decline to give these guys any personal info or even the time of day.
