• Why Pick Us

Our Credentials

It takes a lot to succeed in the Solar Industry for 19 years.

We are proud of the reputation we have built.

Better Business Bureau

The last thing we like to hear from customers is that they had a bad experience with another solar company. Solar is a competitive market and there are many companies out there who are in it for the wrong reasons. Third Sun Solar has been a member with the BBB for 18 years, an A+ rating, and many reviews from happy customers. 

5 NABCEP Solar PV Installation Professionals

NABCEP (North American Board of Certified Energy Practitioners) is the “gold standard” certification in the solar industry. Third Sun is proud to have 5 Certified Installation Professionals on staff.  Third Sun Solar President, Geoff Greenfield, is the Vice-Chair of the NABCEP Board of Directors. 

Benefit Corporation

We operate with a triple bottom line commitment to people (our employees and their families, our clients and residents of the communities where we do business), planet (we appreciate the wonders of nature and believe that a habitable planet is worth fighting for) and profit (generating capital to keep increasing our impact and revenue to share among our team and partners).

Amicus

Amicus is a purchasing cooperative made up of friendly solar installers. This cooperative model allows Third Sun Solar, an average sized regional solar business, to negotiate equipment purchases as though it were a $500 Million company.  Membership in Amicus Solar allows Third Sun Solar to achieve scale while still maintaining the speed and nimbleness, as well as the “family business feel” of a smaller local company.
