I wish they would stop calling me. I block them and they still call with a different number. I have solar on my home and when they are told they say I don't have enough. How do they know. Yes, we do save. Our electric bill is only a couple of dollars a month and we still conserve energy. What they don't tell you is if/when you have the cost added on to your property tax your property tax bill will jump up to $17,000 a year. Just got ours and nearly fell over.
