What is the Delaware Low To Moderate Income Solar Grant Program...

The DNREC Low- to Moderate-Income (LMI) Solar Pilot Program is meant to bring renewable energy to a segment of the Delaware population that has historically been underserved by existing state programs and incentives.

Grant funding is available to promote the use of renewable energy in Delaware for low- and moderate-income households. The LMI program will be used to develop a statewide solar program that will provide services for low- to moderate-income homes regardless of their electric utility service territory.

How Much Can You Save With Delaware Solar Grants?

Delaware Solar Grants can cover a significant portion of your solar installation costs, making going solar more affordable than ever. Depending on your system size, eligibility, and available state incentives, homeowners can typically save between 70% and 100% on their solar installation. These grants are designed to reduce upfront expenses, maximize long‑term energy savings, and make clean energy accessible for Delaware residents.

How to Apply for Delaware Solar Install Grants

To qualify for Delaware Solar Grants, applicants must meet the eligibility requirements of one of the two available income‑based programs. Each program provides a different level of financial support, ensuring that solar energy remains accessible to households across the state.

If you qualify for the Low‑Income Program, your solar installation may be covered at 100%, meaning your system is installed at no cost to you. This option is designed to remove all financial barriers and allow qualifying homeowners to transition to clean energy without any upfront investment.

If you qualify for the Moderate‑Income Program, the state will cover approximately 70% of your total installation cost. This substantial incentive significantly reduces your out‑of‑pocket expenses and makes solar energy an affordable, long‑term solution for reducing utility bills.

Both programs are structured to help Delaware residents access reliable, renewable energy while maximizing savings and minimizing financial burden
