Solar Energy, Small Hydropower, and Geothermal Tax Credit (Corporate)

Value:Up to $3,500

South Carolina businesses are eligible for tax credits on the equipment and installation expenses of a new renewable energy system or energy-efficient building materials. Qualifying technologies include solar, hydroelectric, and geothermal as used to generate electricity or for heating/cooling. All system components are also eligible for credits. The credit is valued at 25% of costs up to $3,500 per property and $5,000 per company. To claim the credit, interested businesses should obtain the proper paperwork from the South Carolina Department of Revenue.

Santee Cooper - Rooftop Solar Rebate Program

Value:Up to $6,300

Residential and small commercial Santee Cooper customers may be entitled to rebates on new rooftop solar panels used for photovoltaic energy. Installations must be performed by a participating contractor and meet certain performance and safety standards. Additional information is available from the Santee Cooper website.

ConserFund Loan Program

Value:Varies

ConserFund is a loan initiative overseen by the South Carolina Energy Office. Loans support state/local agencies, public colleges and schools, and nonprofits in making energy efficiency improvements, including installing new renewable energy devices. Qualifying projects include building retrofit work, geothermal pumps, solar panels, or biomass systems. The available principal per loan varies from $25,000 to $500,000 depending on the nature of the project. The borrower has six months to begin installation from the time of the loan's disbursement. Qualifying public-sector borrowers may have 30% of their loan principal automatically forgiven.

Net Metering

Value:Varies

South Carolina electric customers using an interconnected solar or wind energy system may enter net metering agreements with their utility. Any system rated for under 20 kW (residential) or 1 MW (nonresidential) qualifies. The utility will install a bidirectional meter onto the system to measure net excess generation (NEG) sent back to the grid. Customers will receive energy bill credits for the NEG they generate at a fixed avoided-cost rate. Excess bill credits that remain at the end of the year will be paid as a lump sum. Additional information is available from individual utilities. Utilities may set their own net metering terms within a certain domain.

South Carolina Municipalities - Green Power Purchasing

Value:Varies

In 2001, Santee Cooper established a Green Power Program allowing residential customers to purchase renewably-sourced energy at $3 for a 100 kWh block. Commercial customers may purchase 200 kWh blocks at $6. Any customer-member of a South Carolina electric cooperative, as well as customers in Georgetown, may participate. Additional information is available through the Santee Cooper website.

State Building Energy Standards

Value:Varies

New government buildings in South Carolina are subject to green construction requirements. Generally, new occupied state facilities should meet or exceed the standards for LEED Silver certification. Buildings receiving two Green Globes may also meet the standards. By 2020, existing buildings should take measures to cut energy consumption by 20% from a 2000 baseline. Exceptions apply to buildings of certain types, as well as any project where it is determined that project costs would exceed gained energy efficiency. Additional information is available from the South Carolina Energy Office.

Interconnection Guidelines

Value:Varies

Distributed generation and grid interconnection practices have been standardized in South Carolina since 2006. New renewable energy systems in the South Carolina Electric and Gas, Duke Energy, and Progress Energy service areas will be organized into three regulatory tiers based on capacity. A system's tier will determine available permitting processes, fees, review turnaround time, and safety/performance standards. The state requires all interconnected systems to have multiple external disconnect switches. Non-residential system owners are required to carry at least $300,000 of liability insurance on their system.

Renewable Energy Manufacturing Tax Credit

What impacts the cost of solar panels in Williamsburg County, SC?

Your Energy Needs - The cost per watt is decreased with larger solar panel systems, even though the initial cost is greater. Setting up a solar panel system that can cover the electric bill is advantageous to consumers because of the money saved.

Make & Model - Similar to many other products, there are different makes and models of solar panels and mounting equipment on the market. Your contractor’s potential system preferences make it more important to select a reputable installer. Higher quality makes and models often provide a more positive long-term experience for buyers.

Solar Panel Type - Monocrystalline panels are generally accepted as the standard in the industry, and deservedly so. Even though they are more expensive, they generate more energy. The majority of installers work with panels constructed from this material.

Your Property - No two homes or properties are the same. Elements such as trees, uneven ground, or additional obstacles might complicate the installation process. These days, the majority of solar installers can assess your home with satellite images and factor in these considerations in the preliminary cost estimate.

Labor Rates - Various wages are offered to employees by various companies, and these expenses are transferred to the consumers. Higher wages frequently lead to companies getting better reviews for their work and customer service.

Permitting & Interconnection - Local permitting and utility interconnection fees, which differ by region, will influence your final installation cost. Experienced local installers will incorporate these numbers into your first quotes to avoid any surprises.
