I used Maine Solar to put in an array about 5 years ago. We looked at ReVision and Assured too. Forgot why we didn’t go with Assured, but ReVision was booked out 3 months while MSS could do it in 3 weeks. They were a tad more expensive but not outrageously so.

We’ve since had them out twice to deal with issues caused by faulty inverters from SolarEdge. Both times they were really helpful and worked to get to the bottom of the issue. We’re now on our third inverter from SolarEdge, but that’s not MSS’s fault.

Would definitely recommend them.
