Installation of Residential Solar System

The system has been completed and approved for grid connection. Our smart meter monitor shows good solar output during the hours, sometimes even when there are cloudy periods. We’re awaiting our first bill to get first results.

Wonderful solar experience and partnership

I selected WindFree Solar from a lengthy review of multiple installers, and WindFree stood out in how quickly they were ready to proceed and financing. Their team walked me through each step and were able to move quickly, and my system was up and running! After comparing experiences with friends with other installers, I'm very grateful for the level of communication and advocacy through the process I received with WindFree, and I confidently recommend them to friends.

Professional and as promised

Top notch installation, knowledgeable and responsive team. The Windfree solar team kept us in the loop every step of the way. They were professional and other than having solar panels you would never know they were at the house. Highly recommend the Windfree solar team.

A breeze to do business with

Windfree Solar was so comfortable to work with. They were informative and patient in explaining the steps in the process of getting my home set up with solar. From beginning to end, and with patient ongoing support, they have been true professionals, from sales to on time, courteous installation to ongoing support. I'm very pleased with this company and I highly recommend choosing Windfree.
