Frequently Asked Questions
The average payback period for a purchased solar system in Delaware is typically between 7 and 11 years.
Yes. Solar panels produce electricity based on daylight, not heat, and they are actually more efficient in colder temperatures. While snow can temporarily cover panels, their dark, angled surface helps it melt and slide off relatively quickly.
It depends on your local municipality. Delaware does not have a statewide property tax exemption for solar, so you should check with your local tax assessor’s office.
