What kind of business hides their name at all costs? They are fraudsters. Do not call them. They aren't from APS or any government agency. Their flyer claims "qualified" houses get solar at no cost, the next sentence days they'd save 21% to 34% off their bill. Knowing how dishonest they are, it's probably no more than 20% which is nothing. $20 off a $100 winter bill? Not worth the hassle and dealing with a shady business
This number is included as a survey or interest contact for rooftop solar on a fake, government looking door hanger saying people are qualifying for no cost solar, and a roof surveyor will be in the neighborhood looking for qualified homes/customers. The premise of the door hanger is false and misleading. It's a scam and a sales tactic.
