Solar Panel Installation in Mount Prospect FAQs

Is solar worth it in Mount Prospect?

The sun is strong (about 1,070 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 Illinois 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. Illinois has no state solar income tax credit that we found; its state help is the Illinois Shines payment, utility rebates and a property tax valuation rule (35 ILCS 200/10-10).

Do I need a permit for solar panels in Mount Prospect?

Usually yes, and the utility may need to approve solar and batteries. Village of Mount Prospect Building and Inspection Services handles permits in Mount Prospect; see the permit information above.
