Complete Guide to Solar Energy in Indiana
Your complete resource for solar energy. Everything you need to know about solar laws, solar costs, solar financing, and solar installation in Indiana.
Why Indiana is Excellent for Solar Energy
Reliable Solar Potential
Indiana receives 186 sunny days per year, which is enough to support strong residential solar production when systems are properly sized and positioned. Long summer daylight hours and steady year-round solar exposure make Indiana a practical solar market for homeowners looking to reduce utility dependence.
Rising Electricity Costs
Residential electricity prices in Indiana reached 16.19¢/kWh, making solar more attractive as monthly utility bills rise. For households with higher daytime usage, rooftop solar can deliver meaningful long-term savings and greater protection from future rate increases.
Valuable State Tax Benefits
Indiana offers a property tax exemption for qualifying renewable energy systems, helping homeowners avoid higher taxes on the added value solar can bring to a property. The state also exempts qualifying solar system components from gross retail tax, which can improve project economics.
Clear Solar Access Rules
Indiana recognizes solar easements and also limits how HOAs can restrict solar through H.B. 1196. While most new systems no longer receive traditional retail-rate net metering, homeowners can still benefit from solar by designing systems around self-consumption and Indiana’s excess distributed generation rules.

Important 2026 Updates
Solar Economics Changed After the Federal Credit Ended
The Residential Clean Energy Credit expired for expenditures made after December 31, 2025. Even without the former federal credit, solar can still make sense in Indiana because of rising electricity prices, state-level tax treatment, and the state’s growing installer market.
Net Metering Has Shifted to Excess Distributed Generation
Traditional retail-rate net metering has largely been phased out in Indiana under Senate Bill 309. Most new customers now receive utility-specific compensation under excess distributed generation rules, while some earlier customers remain grandfathered under older timelines.

Federal Tax Credit Expired
The federal residential solar tax credit is no longer available for new post-2025 residential installations. Homeowners in Indiana now need to evaluate solar primarily based on electricity savings, tax treatment, system design, and local utility compensation rules.
Solar Easements & HOA Protections
Indiana law recognizes solar easements and provides added homeowner protection through H.B. 1196, which limits how HOAs can restrict solar panel installations. Homeowners should still review association rules and placement standards before installing.
Property Tax Exemptions & Export Rules
Indiana also provides a renewable energy property tax exemption and a gross retail tax exemption for qualifying solar system components. Exported electricity from most new systems is handled under excess distributed generation tariffs rather than full retail net metering.
