Solar Panel Installation in Hammond FAQs
Is solar worth it in Hammond?
The sun is strong (about 1,360 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 Louisiana 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. Louisiana’s state solar income tax credit has ended (Act 413 of 2017), but home solar equipment is exempt from property tax (R.S. 47:1706).
Do I need a permit for solar panels in Hammond?
Usually yes, and the utility may need to approve solar and batteries. City of Hammond Building Department handles permits in Hammond; see the permit information above.
