We recently installed solar collectors on our roof, with Main Solar Solutions. They came and measured our roof, presented us with two proposals (we took the larger one), walked us through the process of dealing with Central Maine Power, then did the installation. Our electric bill has decreased from an average of over $250 per month to most recently $21.55, which is CMP's monthly service charge. All the people we dealt with at Maine Solar Solutions have been courteous, proficient, careful and prompt. Everything happened exactly as they said it would. We were happy to deal with Maine Solar Solutions and are happy to recommend them enthusiastically. Additionally, we are looking forward to receiving the 30% tax credit on our 2024 federal income tax!
