2025 Solar Panel Incentives in South Carolina: What’s New

South Carolina’s Solar Landscape in 2025

South Carolina continues to shine bright in the solar energy sector for 2025. With the Palmetto State’s abundant sunshine and progressive energy policies, homeowners and businesses across Greenville, Spartanburg, and Anderson have more reasons than ever to consider solar power. This year brings significant updates to incentives, tax credits, and rebate programs that make going solar not just environmentally sound but financially savvy too. As your local solar experts since 1995, we’ve compiled everything you need to know about the latest incentives that can help you save thousands while contributing to a cleaner energy future in South Carolina. In addition to residential options, there are also numerous commercial solar programs in South Carolina that provide businesses with unique opportunities to reduce energy costs and enhance sustainability. These programs are designed to cater to different business sizes and types, ensuring that every company can benefit from the shift to solar energy. By taking advantage of these incentives, businesses can not only improve their bottom line but also demonstrate their commitment to environmental responsibility.

Federal Solar Investment Tax Credit: 2025 Updates

The federal solar investment tax credit (ITC) remains one of the most substantial financial incentives for solar adoption. In 2025, the federal tax credit stands at 30% of your total solar system cost. This means if you install a $20,000 solar system, you could receive a $6,000 tax credit on your federal tax return. What’s important to note for 2025 is that this rate is locked in until 2032 thanks to the Inflation Reduction Act, providing long-term certainty for those considering the switch to solar.

New for 2025 is the direct pay option for non-profits and government entities that previously couldn’t take advantage of the tax credit due to their tax-exempt status. Additionally, battery storage systems now qualify for the ITC even when installed separately from solar panels, opening new opportunities for energy independence.

South Carolina State Tax Credit Changes for 2025

South Carolina continues to offer one of the most generous state solar tax credits in the nation. Residents can claim 25% of their solar system costs as a state tax credit, up to $3,500 per year or 50% of your state tax liability, whichever is less. If your credit exceeds your tax liability, you can carry forward any unused amounts for up to 10 years. In addition to the immediate financial relief, the South Carolina solar tax credit benefits also encourage homeowners to invest in renewable energy, promoting sustainability and energy independence. As more residents adopt solar energy systems, the state can expect a boost in job creation within the green energy sector. Furthermore, these incentives contribute to reducing overall energy costs and enhancing property values for those who make the switch to solar power.

What’s new in 2025 is the expansion of eligibility criteria for this credit. The state has broadened the definition of qualifying solar equipment to include certain types of solar shingles and building-integrated photovoltaics, giving homeowners more aesthetic options while still qualifying for the tax incentives.

Utility Rebates and Programs: New Offerings

South Carolina’s major utilities have introduced new incentive programs for 2025. Duke Energy’s Smart $aver Solar Rebate now offers residential customers $0.50 per watt of installed capacity, up to $5,000. Dominion Energy has launched its new Sun Support Program, providing upfront rebates of $0.40 per watt up to $4,000 for residential systems. These initiatives aim to encourage the adoption of renewable energy sources and reduce overall energy costs for homeowners. For more information on specific offerings, customers can review the duke energy solar rebate details, which outline eligibility requirements and application processes. Additionally, these programs not only benefit individual consumers but also contribute to the state’s overall sustainability goals.

A significant development for 2025 is the introduction of time-of-use (TOU) rate structures by most SC utilities. These new rate plans can substantially increase the value of your solar investment by rewarding energy production during peak demand hours when electricity from the grid is most expensive. When paired with battery storage, these new rate structures can boost your solar savings by an additional 15-20% compared to standard net metering.

Net Metering Policy Updates

Net metering in South Carolina has undergone important changes for 2025. The good news is that the state has extended its net metering program through 2029, ensuring that new solar customers will continue to receive credit for excess energy fed back to the grid.

However, the credit rate structure has been modified. New solar customers will now receive credits at approximately 75-80% of the retail rate, depending on their utility. While this is a reduction from the previous 1:1 credit system, solar installations still provide excellent financial returns when all incentives are considered. Existing customers are grandfathered into their original net metering agreements for 20 years from installation.

Property Tax Exemptions for Solar

Starting in 2025, South Carolina has implemented a new statewide property tax exemption for residential solar systems. This means your property taxes won’t increase despite the added value a solar system brings to your home. This exemption applies to 100% of the value added by your solar system and has no expiration date, providing long-term savings for homeowners.

Commercial properties now benefit from an expanded 80% property tax exemption on the value of their solar installations, up from the previous 60% exemption. This change makes commercial solar more attractive than ever for businesses across Upstate South Carolina.

Community Solar Access Expansion

2025 marks the launch of expanded community solar programs across South Carolina. These programs allow residents who can’t install solar on their own properties (renters, those with unsuitable roofs, or homeowners with excessive shading) to subscribe to a portion of a larger solar array and receive credits on their electric bills.

The new “Solar for All” initiative specifically targets low to moderate-income households, offering subsidized subscription rates and guaranteed savings. This program makes clean energy access more equitable and provides savings opportunities for a broader range of South Carolina residents. Additionally, the initiative aims to create job opportunities in local communities through training programs related to solar technology. By promoting solar panel funding for businesses, it encourages entrepreneurial engagement and supports the growth of green industries. This holistic approach not only enhances energy independence but also stimulates economic growth across the state.

Electric Vehicle Integration Incentives

New for 2025 are incentives that specifically target the integration of solar power with electric vehicles. South Carolina now offers an additional $1,000 state tax credit for installing EV charging equipment powered by on-site solar generation. This creates a powerful synergy for homeowners looking to embrace both solar energy and electric transportation.

Several utilities have also introduced special EV charging rates for solar customers, with significant discounts for charging during solar production hours, maximizing the use of your own clean energy.
