Power your future with OnSite Energy

Our customers rave about our exceptional service and seamless solar installations—don’t just take our word for it, see what they have to say!

Given the uncertain availability and rising costs of fossil fuels, we believe solar energy is the way to help transition from oil, gas, and coal to clean energy. While the initial price might seem high, with the incentives and years of low to zero power bills, it is well worth the investment the long term, especially given ongoing increases in the economic and environmental costs for electricity generated by fossil fuels.

We picked OnSite Energy to do our solar installation because they were highly rated, they are a B Corporation, and we appreciated our initial conversations with their staff. We couldn’t be more pleased with the folks we worked with at OnSite from the people in the office to the crews on the ground. The planning, installation, and performance of the system have all been great. We give them our highest rating and we recommend them to folks we talk with who are interested in solar energy.
