We used SunBug Solar. Our friends used them and highly recommend them. We've sent many of our friends to them, they were terrific.

They came out to do a quick assessment of the roof, shade, attic, electrical panel capacity and discuss our expectations for how much of our electricity we wanted the system to cover. They were also helpful with how it works in MA, the state of the Solar Renewable Energy Credit (srec) program and also the MA Dept. Of Energy Resources (DOER).

They came back with a couple quote options and we haven't regretted it once.

This was a while ago so things may have changed but I know net metering is still happening. SRECs may not be but I believe there is still a renewable energy credit program. There's likely a federal and state tax credit as well and it all helps get the total cost down.

When we got them MA had capped interest rates on solar loans around 3% but we called a number of banks and secured a loan at 1.25%.

We also have zero shade on our roof so we have great production. They have paid for themselves. SunBug should also be able to give you an estimate for your return on investment.
