Your application paperwork

Washington's Solar for All program, funded through the federal Greenhouse Gas Reduction Fund, brings the benefits of solar to income-qualified residents. It offers no-cost solar installations for income-qualified single-family homeowners and no-cost community or shared solar participation for renters. The Department of Commerce runs it through selected program partners.

Steps to apply

  1. Confirm you are an income-qualified Washington homeowner (or a renter interested in community solar).
  2. Visit the Commerce Solar for All page to find the current program partners and how to enroll.
  3. Contact a participating partner to check eligibility and start enrollment.
  4. If eligible, the partner arranges the no-cost solar installation.

Documents you will likely need

  • Proof of household income to confirm you are income-qualified.
  • Proof you own and live in the home.
  • A recent electric bill.
  • A government-issued photo ID.

Requirements vary by program and locality. Confirm the exact rules on the official program page. We can help you prepare your paperwork, but you submit it yourself.

Deadline: Enroll within 6 months of system installation
