We used SunBug to have roof panels installed a number of years ago. They were recommended by some friends and were great.

We haven't paid an electric bill since and actually just received a Christmas card from them. Highly recommended.

They came out to take some measurements, look at our attic, review past electric bills and then discuss panel options and costs. They were very relaxed and helpful.

The install took 2 days and included a few posts to add support to the roof. The cost was around 15k.

We were able to take advantage of a federal credit, state credit and were able to get in on the Solar Renewable Energy Credit so each quarter we can sell a megawatt to an aggregator and get paid a few hundred dollars. This is in addition to the credit we've amassed due to producing more than we use, net metering is amazing.

Interest rates for solar loans were capped around 3% at the time but we were able to get 1.5% by calling a few banks.
