Utility rules and programs for Lafayette
Duke Energy Indiana and Tipmont Rural Elec Member serve Tippecanoe County, so which rules apply depends on your address.
| Utility | Type | Solar export rule |
|---|---|---|
| Duke Energy Indiana, LLC | investor-owned | Duke credits exported solar power under its Excess Distributed Generation rider at 1.25 times its average market price for the prior year (IURC approved it July 6, 2022); Solar United Neighbors lists about 5.5 cents per kWh for 2026, but we could not read Duke’s own tariff, so confirm it. Power you buy still costs the retail rate. |
| Tipmont Rural Elec Member Corp | member-owned cooperative | Tipmont is a rural electric cooperative and sets its own solar export rule; we could not confirm it. |
Program details are from each utility’s own pages (read October 2026). See the Indiana incentives table for statewide credits and a status for every program.

Solar Panel Installation in Lafayette FAQs
Is solar worth it in Lafayette?
The sun is strong (about 1,160 kWh a year per kW, our estimate), but export credits are low, so solar pays most when sized to what you use at home or paired with a battery. See the Indiana incentives for the state credit.
Is there a federal solar tax credit in 2026?
No. The federal 25D credit ended for expenditures after December 31, 2025. Indiana has no state solar tax credit that we found; the only state-level break is a solar property tax deduction claimed on State Form 18865 with your county auditor.
Do I need a permit for solar panels in Lafayette?
Usually yes, and the utility may need to approve solar and batteries. City of Lafayette Office of the City Engineer (Permits) handles permits in Lafayette; see the permit information above.
