Detailed Profile
SunPower serves the South Carolina market from their North Charleston operations, bringing 19 years of presence in the Palmetto State. South Carolina offers one of the stronger state solar incentive packages in the Southeast, with a 25% state tax credit, sales and property tax exemptions, and net metering, making it an attractive market for quality installers.
What earned SunPower the top ranking in South Carolina was their established brand and 4.3-star rating from 465 reviews. While the rating is lower than some competitors, SunPower's proprietary high-efficiency panels, 25-year warranty, and NABCEP certification provide a level of product quality and long-term assurance that smaller local companies struggle to match.
The company helps customers maximize South Carolina's state tax credit and other incentives. Their presence in the Charleston market gives them familiarity with the coastal building codes and humidity-related considerations specific to the Lowcountry.
With a composite score of 76.6, SunPower is our top-ranked solar company in South Carolina for 2026.
