Get answers to common questions about home solar services in Marietta, South Carolina.
For a typical Marietta home, a 6-8 kW solar system costs between $15,000 and $25,000 before incentives. South Carolina offers a 25% state tax credit (capped at $3,500 or 50% of tax liability) on top of the 30% federal tax credit, significantly lowering your net cost. Additionally, you can benefit from net metering with Duke Energy, which is the primary utility serving the area, allowing you to earn credits for excess power sent to the grid.
Marietta's climate is favorable for solar, with ample sunshine averaging over 210 clear days per year. While summer heat can slightly reduce panel efficiency, the longer daylight hours in summer lead to peak production. Seasonal variations mean you'll generate more in the sunny, long days of spring and summer than in the shorter, cloudier winter days, but the system is designed to produce a reliable annual average.
It's crucial to choose an installer licensed in South Carolina with extensive experience navigating Duke Energy's specific interconnection and net metering requirements. Look for a provider with a strong local reputation, physical presence, and familiarity with Greenville County's permitting process. Always verify they are certified by the North American Board of Certified Energy Practitioners (NABCEP) and check reviews from Upstate SC homeowners.
From contract to activation, the process typically takes 2 to 4 months. This timeline includes system design, securing permits from Greenville County, Duke Energy's interconnection approval, installation, and the final inspection. Delays can occur during the utility approval phase, so working with an experienced local installer who knows how to efficiently manage this process is key.
Yes, tree shading is a common concern given Marietta's wooded, suburban lots; a professional site assessment will determine if trimming or selective removal is needed for optimal sun exposure. Many homes in the area have architectural shingle roofs, which are ideal for solar mounting, but installers must also assess roof age and structure. Local installers are also adept at designing systems that can withstand the occasional severe thunderstorms and hail experienced in the region.
