** The home solar market in Great Falls, SC, is characteristic of a small, rural town. There are no solar installation companies physically headquartered within the Great Falls city limits. Therefore, the market is served exclusively by reputable regional and national companies based in larger nearby hubs such as Columbia, Lexington, and Charlotte. The competition level is moderate, with several strong contenders vying for homeowners in the area. The average quality of service is high, as the companies that expand their reach to smaller towns tend to be well-established and credible. Typical pricing for a residential solar system in South Carolina is competitive, with average gross costs ranging from $15,000 to $25,000 before applying the 30% federal tax credit and any local utility incentives. Homeowners in Great Falls benefit from South Carolina's net metering policies and the state's former solar tax credit, which has now expired but helped build a robust installer network.

Get answers to common questions about home solar services in Great Falls, South Carolina.
For a typical 6-8 kW system in Great Falls, the gross cost before incentives ranges from $18,000 to $28,000. Crucially, South Carolina homeowners benefit from the 30% federal tax credit and the state's 25% tax credit (capped at $3,500 or 50% of tax liability), which together can reduce your net cost by over 50%. Additionally, South Carolina offers a full property tax exemption for the added value of your solar system, protecting you from higher property taxes.
Great Falls' humid subtropical climate provides ample sunshine, with about 215 sunny days per year, which is excellent for solar production. While summer heat can slightly reduce panel efficiency, the long daylight hours still yield high output. The main seasonal consideration is occasional winter cloud cover; however, modern panels are effective in diffuse light, and systems are designed to produce ample annual energy to offset your usage across all seasons.
Prioritize installers licensed in South Carolina with strong local experience, as they will understand Duke Energy's interconnection process and local building codes. Check for certifications like NABCEP and read reviews from nearby homeowners. It's essential to get multiple detailed quotes that specify equipment, production estimates for our climate, warranty terms, and a clear timeline for permits, installation, and the utility approval process.
From contract to activation typically takes 2 to 4 months. The timeline includes system design, securing permits from Chester County, the physical installation (1-3 days), and the crucial inspection and interconnection approval from Duke Energy. Scheduling the final utility meter swap can sometimes cause short delays, but a reputable local installer will manage this process efficiently.
It is extremely rare and costly to go fully off-grid in Great Falls due to our climate; you would need a massive battery bank to cover multiple cloudy days. Nearly all homeowners opt for a grid-tied system with Duke Energy under net metering, which acts as a virtual battery. South Carolina's net metering law requires Duke Energy to credit you for excess power sent to the grid, making a grid connection financially beneficial and reliable.
