Actually, solar people don't call that much anymore. There are new energy saving products on the market that are being pushed hard., such as double-pane windows, energy efficient house paint, etc. etc.
8/07/15 9:42 PDT Suddenly receiving multiple calls from "Riverside CA". Based on other recent reports, will guess probably scammers. Will continue to ignore these calls. There was a sort of message. Some fool expecting a response to his hello from my voice mail.
