Solar Energy Partners

Solar Energy Partners has built a focused Upstate South Carolina residential solar practice from a permanent Greenville office at 355 South Main Street, and the company's combination of premium-tier equipment and recent third-party recognition earned it the third spot in our 2026 ranking. The broader Solar Energy Partners organization was incorporated in 2017 with corporate offices in Smyrna, Georgia, and the Greenville location operates as a fully staffed field office serving the Upstate, the I-85 corridor, and adjacent counties. The South Carolina office holds full General Contractor and Electrical Contractor licensing for the state, and the company carries an A+ rating with the Better Business Bureau.

What stood out to our research team is the equipment specification. Solar Energy Partners is a Maxeon Preferred Partner, which means homeowners get access to the Maxeon residential solar cell — historically the same cell technology that anchored the original SunPower premium product line — paired with Enphase microinverters or SolarEdge string inverters depending on shading and array geometry. The company is also Tesla Powerwall Certified, a FranklinWH Certified Installer, a SPAN Authorized Installer, and an Enphase certified partner. Their NABCEP-board-certified team and Solar Stack and Schneider certifications round out a credential stack that is genuinely above the South Carolina market average.

On the recognition side, Solar Energy Partners holds the EnergySage Elite Installer designation and was named the 2026 EnergySage Installer of the Year, an award based on verified-customer review aggregation across the EnergySage Marketplace. Their EnergySage rating sits at 4.8 out of 5 across 19 verified reviews, and customer comments consistently cite responsive ownership, clean installations, and willingness to revisit site design when shading or roof complications surface.

That said, this is a younger operation than the two installers above it, and our research team did identify mixed feedback around project-timeline management — including one documented case of a roofing-subcontractor handoff that stretched into a multi-month delay. Prospective customers should ask directly about realistic install timelines, in-house versus subcontracted roofing work, and the warranty terms that flow through from Maxeon and the inverter manufacturers.

With a composite score of 71.2 out of 100, Solar Energy Partners holds the third-ranked position in South Carolina for 2026.
