A company came home and offer the solar panels installed for $40k. The return in taxes and the savings in electricity bill will pay the $40k bank loan during the next 10 years.
My answer was that if I were 20 years younger, I will do it, because it will be for FREE...after 10 years....because for now instead of paying the electric bill I will have to pay the bank loan. At 57 years old and not knowing if I will stay in MA at my retirement in 10 years, I declined. I decided to continue paying the electric bill. And the future home owner can deal with the solar panels.
My house is well positioned and I already bought the house with a Water Solar Panel Heating System that save me lots of $$$$ because we do not have town gas here.
Cheers

Ps: my electric bill is around $250-275/month with 2 Marine tanks and 3 freshwater tanks. And remember that my heating water house system use more electricit in winter due to a lower sun intensity. But in summer I have the ACs. So one compensate the other on the different season's
