** The home solar market in Union, South Carolina, is characteristic of a smaller, rural city served by larger regional and national providers. There are no major solar installation companies headquartered directly within the city limits of Union. Therefore, the market is dominated by established companies from Greenville, Spartanburg, and Columbia, as well as national players like Tesla who operate via centralized scheduling. The competition level is moderate, with several reputable companies vying for business in the broader Upstate SC region. This is beneficial for consumers, as it encourages competitive pricing and service quality. The average quality of providers available to Union residents is high, as they must meet state licensing and insurance requirements. Typical pricing for a residential solar system in South Carolina ranges from **$15,000 to $35,000+** before incentives, heavily dependent on system size (typically 6kW to 12kW for an average home) and the inclusion of battery storage. The federal solar Investment Tax Credit (ITC), which currently allows for a 30% tax credit, significantly reduces the net cost. South Carolina also offers a state tax credit and property tax exemption, making solar a financially attractive option for many homeowners in the area.

Get answers to common questions about home solar services in Union, South Carolina.
For a typical 6-8 kW system in Union, the average gross cost ranges from $18,000 to $25,000 before incentives. Crucially, South Carolina homeowners benefit from a 25% state tax credit (on top of the 30% federal tax credit) and property tax exemption for the added home value from solar. You should also check with Union County or your specific utility for any additional rebates.
Union's climate is excellent for solar, with ample sunshine averaging over 210 sunny days per year. While summer offers the most peak production, our mild winters with infrequent snow mean panels can generate meaningful power year-round. Seasonal shifts in the sun's angle and occasional summer cloud cover are factored into professional production estimates.
Prioritize installers licensed in South Carolina with strong local experience, as they understand Union County's permitting process and Duke Energy's interconnection requirements. Check for certifications like NABCEP, read local reviews, and insist on multiple in-home consultations to compare system designs, equipment quality, and warranty terms specific to our area.
From contract to activation typically takes 2 to 4 months. The timeline includes system design, securing permits from Union County, Duke Energy's interconnection agreement, the physical installation (1-3 days), and finally the county inspection and utility's "Permission to Operate" approval. A reputable local installer will manage this entire process for you.
Standard grid-tied systems shut off during an outage for safety, unless paired with a battery backup. For severe weather like summer thunderstorms or hail, panels are rated to withstand impacts (typically hail up to 1 inch in diameter at high speed). Your installer should ensure proper mounting to meet local wind codes and may recommend comprehensive insurance coverage.
