Based on our experience, I strongly recommend Maine Solar Solutions. They were knowledgeable, helpful, and professional throughout the entire process, and the level of service was really excellent. Our system required a transformer upgrade -- that's something CMP has to do, and they delayed a long time in doing it. Maine Solar has no control over that, but pretty much the instant CMP was finished upgrading the transformer, Maine Solar came over on very short notice to turn on our system. If I haven't explained this well enough, here's the bottom line: Maine Solar Solutions went above and beyond to get our system up and running.I can't say too much about the system itself yet, as it was just turned on this morning, but all of our panels are operational and currently generating some power even on a cloudy December morning. But based on the service we've gotten so far, if we do encounter any problems or issues in the future, I'm pretty confident that Maine Solar Solutions will do whatever they can to resolve them quickly. All in all, I'm very satisfied, and would definitely recommend them!
