"We chose Invaleon because our salesman, Charles Roche, made it a no-brainer. He was able to answer all our questions, and walk us through the loan process and the State incentive program. Charles was not a pushy salesman, but a matter-of-fact person. I would happily use them again. Our system outperforms the estimates by a long shot. In the year 2020, we paid a grand total of -$1,610. That's right, we get paid by the electric company for our extra output and we make a profit."
