Before any plans are finalized, a thorough site assessment of your Charlestown NH property accounts for roof orientation, shading, your household's energy usage, and your long-term goals. Each solar energy system is tailored to those specific conditions.

Every step of your installation in Charlestown is managed for you, from permitting through final grid connection. Bergeron Mechanical Systems coordinates the work from start to finish, so you never have to navigate the process on your own.

For Charlestown homeowners in rural areas where grid service can vary, solar battery backup offers real, practical value. Store the energy your panels generate during the day and use it when you need it, independent of what the utility grid is doing at any given moment.

Pair your solar energy system with Mitsubishi Electric mini-splits to reduce your dependence on both the grid and fossil fuels for home heating and cooling. The combination is especially effective for Charlestown New Hampshire homeowners working toward year-round energy independence.

Highly recommended for heat pumps. From initial meeting with Monique we were given information and advice to get the best option for us. The installation team of John, Mitchell, Nils, and Lincoln were efficient and professional. They took care in our home and were friendly and helpful.
