Quick Answer: Solar Permits & Incentives in Kentucky
Local city or county authorities, not a state agency, issue solar permits in Kentucky. Typically, a building permit and an electrical permit are required. The inspection process follows local adoption of the Kentucky Building Code.
Financially, the federal Residential Clean Energy Credit (IRS §25D) covers 30% of total system cost with no cap through 2032. Kentucky offers a sales tax exemption for qualifying solar components, according to the Kentucky Department of Revenue. For cooperative members, the Together We Save program may provide additional rebates. Once operational, net metering allows excess generation to be credited on your utility bill. The Kentucky Public Service Commission (PSC Order 2008-00169) sets the rules for net metering.
| Incentive | Type | Value |
|---|---|---|
| Federal ITC (IRS §25D) | Tax credit | 30% of system cost |
| KY Sales Tax Exemption (IEIA) | Sales tax relief | Varies by project scale |
| KY Sales Tax Exemption (Machinery) | Sales tax relief | Components used in production |
| Together We Save (Cooperatives) | Utility rebate | Varies by cooperative |
| Net Metering | Bill credit | Retail rate for excess kWh |
