Louisville/Jefferson County Solar Panel Installation Incentives & Rebates | 2025

The REAP Grant can potentially cover between 80% and 100% of the installation costs for solar energy or wind turbines for rural small businesses and agricultural businesses. If you feel you might be eligible, try our REAP Grant eligibility tool to confirm your qualification.

Homeowners can benefit from a 30% federal income tax credit for installing residential solar panels, making solar power a feasible option in much of the country. A number of state and local programs are set up to enhance the adoption of solar energy.

There are 6 solar incentive and rebate programs in Kentucky, provided by different utilities and governmental agencies.

Tax Exemption for Large-Scale Renewable Energy Projects

Value:Varies

Beginning in 2007, companies operating in Kentucky may be entitled to corporate sales or income tax exemptions on new energy efficiency or renewable energy investments. A complete sales tax exemption may apply to any materials or equipment a company uses to make improvements. Certain employees whose jobs were created as part of the improvements may write off a 4% wage assessment on their own income taxes. A minimum investment of $1 million is required. New solar facilities should be rated for at least 50 KW, while systems using other renewable technology should be rated for at least 1 MW. Additional information is available from the Think Kentucky website.

On-Farm Energy Efficiency Grant Program

Value:Varies

The Office of Agricultural Policy, a unit of the office of the Kentucky governor, oversees the County Agricultural Investment Program (CAIP). Farmers may be eligible for program grants to fund energy efficiency improvements. Eligible projects for grant funding include new implements, insulation/weatherization, lighting, HVAC, windows, roofing, and smart thermostats. New solar thermal/PV systems and wind turbines may also be eligible. Equipment and building materials must meet certain state efficiency standards. Interested farmers may apply at any time and will be considered for the upcoming program year. Additional information is available from the OAP website.

Net Metering

Value:Varies

Kentucky requires private electrical utilities in the Commonwealth to collect renewable energy credits through net metering arrangements with their customers. Any solar, wind, biomass, or other renewable energy system rated for under 45 kW should have a bidirectional meter equipped to measure net excess generation (NEG) sent back to the grid. Customers will be compensated at a rate set by the state utility regulator. As of 2021, the rate per kilowatt hour is 9.746 cents. Systems entering a net metering contract must comply with certain IEEE and UL standards. Utilities reserve the right to restrict NEG exports to keep the grid stable. Additional information is available from the Kentucky Public Service Commission website.

Incentives for Energy Independence

Value:Varies

Various tax incentives are available in Kentucky to encourage renewable adoption research and adoption in the Commonwealth. New renewable generation farms, such as those using solar, wind, or biomass technology, may be totally exempt from state income tax, entity tax, and sales/use tax. Employees maintaining the systems may be entitled to tax credits equal to a 4% wage assessment on employers. Exemptions or special assessments are determined on a case-by-case basis and will last for up to 25 years. Certain administrative fees payable to the Kentucky Economic Development Finance Authority may apply. Additional information is available from the Think Kentucky website.

Energy Efficiency Loans for State Government Agencies

Value:Varies

The Green Bank of Kentucky (GBKY) received seed funding from the 2009 federal stimulus package. Currently, the Bank offers revolving loans to commonwealth government agencies for sustainability projects. Agencies may select from three different loan options. In each case, repaid principal will immediately "revolve" to support subsequent borrowers. SELF loans may fund any energy efficiency improvements or renewable energy investments that will reduce consumption by 20%. Available principal ranges from $50K to a maximum of $225K. Hybrid loans offer principal from $50K to $600K. These loans require energy audits before project work begins, the cost of which may be covered by loan funds. Agencies have the burden of procuring contractors and new equipment/materials. ESPC loans are designed for comprehensive or large-scale industrial improvements. Loan principal starts at $600K with no maximum. The applicant must use a recognized Energy Service Company or Energy Savings Performance Company for the work. Additional information is available from the GBKY website.

Interconnection Standards

Value:Varies

Distributed generation and interconnection have been standardized by the Kentucky Public Service Commission since 2009. Each energy system connected to the commonwealth grid will be assigned to a numerical "level" based on rated capacity. Systems at each level must follow recognized standards such as those set by IEEE or UL. Interconnection fees and application review turnaround will depend on the system's level. Customers must carry at least minimum liability insurance coverage on their energy system, and they may be required to install disconnect switches or other safety features by their utility. However, they will own any renewable energy credits they generate and may sell them to the utility at their discretion.

What impacts the cost of solar panels in Louisville/Jefferson County, KY?

Your Energy Needs - Even though larger solar panel systems are more expensive initially, the average price per watt reduces as the system size increases. Consumers often find that setting up a solar system to fully cover their electric bill is a smart choice, leading to the most savings.

Make & Model - There are a variety of makes and models of solar panels. The contractor’s preference for brand makes it essential to select a recommended installer. Better makes and models typically provide an enhanced long-term experience for the buyer.

Solar Panel Type - There's a good reason why monocrystalline panels are now considered the industry standard. They have a higher price, but they produce more energy. Many solar panel installers prefer this type of material.

Your Property - No two properties or homes are identical. Rough terrain, trees, or additional considerations can increase the difficulty of the installation. Solar installers today frequently utilize satellite imagery to evaluate your home and factor in these factors into the preliminary cost estimate.

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

Permitting & Interconnection - Local permitting and utility level interconnection fees differ by area and will affect your final install price. That said, reputable local installers will be able to incorporate these numbers into your initial quotes so there are no surprises.
