About SunPower Builders
SunPower Builders is one of the longest-operating solar companies in the Philadelphia region, founded in 1972 and based in Collegeville, Pennsylvania. The company has worked in the solar and residential construction industries for over 50 years, supplying and installing photovoltaic systems, solar hot water systems, and pool heating systems for homes and businesses across southeastern Pennsylvania.
The company takes a design-build approach to solar projects, integrating solar energy systems with broader home improvement and green building services. SunPower Builders installs panels from SunPower and REC with Enphase and SolarEdge inverters and offers battery storage from Enphase and Tesla. The company handles system design, permitting, installation, and post-installation support.
SunPower Builders holds a 5.0 rating on Houzz and positive reviews across Angi and EnergySage. The company’s half-century of experience in both solar and general construction gives it a unique advantage in handling complex roof configurations and structural considerations that newer solar-only firms may lack. Customers value the company’s craftsmanship and deep technical knowledge.

William G.
SunPower Builders installed a 10 kW system on our home. Going solar was one of the smarter decisions we've made — the system is paying off more than we estimated. The team's decades of experience really shows in the quality of work.

We chose SunPower Builders for their long track record in the Philadelphia area. The design maximized our roof space and the installation was clean and professional. Great attention to detail throughout.
Steven M.
Solid installation and good system performance. The project timeline was a bit longer than initially quoted, but the end result was worth the wait. The team clearly knows what they're doing after 50+ years in the business.
