SunPower®

SunPower has been one of the most recognizable names in American solar energy for over four decades. The company's Oregon presence is anchored in the Portland metro area, where it has served residential and commercial customers through a network of authorized dealers and, for a period, through its own direct operations. SunPower's history in Oregon runs deeper than most national brands: in 2018, the company acquired the former SolarWorld Americas manufacturing facility in Hillsboro, just west of Portland, and began assembling its Performance Series commercial panels there with a workforce of roughly 200 employees.

That manufacturing footprint gave SunPower a tangible stake in the Oregon solar economy that few national competitors could match. The company built its reputation on panel efficiency, consistently producing some of the highest-wattage residential modules on the market. For Oregon homeowners dealing with the Pacific Northwest's overcast winters and limited peak-sun hours, that efficiency advantage translates directly into better year-round energy production from a smaller roof footprint.

It is worth noting that SunPower filed for Chapter 11 bankruptcy protection in August 2024, and its assets were subsequently acquired by Complete Solaria for approximately 45 million dollars. The brand has since been relaunched, and warranty obligations on existing SunPower-branded equipment continue to be honored. Oregon customers with SunPower systems installed prior to the restructuring should verify their warranty coverage through the current entity operating under the SunPower name.

Despite the corporate turbulence, the installed base of SunPower systems across Portland, the Willamette Valley, and Central Oregon remains substantial. The company's 4.4-star Google rating across 644 reviews reflects a large and generally satisfied customer pool, though some recent reviews reference communication delays during the transition period. NABCEP-certified installers have handled the company's Oregon projects, and its equipment has historically carried some of the strongest product and performance warranties in the industry.

With a composite score of 77.3 out of 100, SunPower holds the second-ranked position among solar providers in Oregon for 2026.
