Colorado Solar For All
Colorado Solar for All
Funding to expand solar energy and save Coloradans money.
The Colorado Energy Office (CEO) is designing the Colorado Solar for All (COS4A) income-qualified program to significantly benefit Colorado residents by lowering energy bills. This initiative will accelerate the adoption of three different solar installation types: single family rooftop, multifamily rooftop solar and community solar (for residential subscribers), ultimately contributing to increased energy independence and financial savings for households through expanded access to solar energy across the state.
Background
The Colorado Energy Office won an award of $156 million from the United States Environmental Protection Agency (EPA) through its “Solar for All” competition, which was established by the federal Inflation Reduction Act of 2022. The program will work with competitively selected, industry-leading partners to deliver, install, operate, and manage solar assets. The program will help expand widespread adoption of rooftop solar in Colorado, moving the state closer to the goal of 100% clean energy by 2040 while improving air quality, lowering energy bills, and increasing energy independence.
The program is currently in development and CEO will continue to keep the public and other partners up-to-date. Be sure to sign up to our COS4A newsletter and check this website for the latest information.

COS4A Programs
Single-Family 100% Subsidy
The Colorado Solar for All Single Family 100% Subsidy Program (SF100) will provide solar at no cost to qualified households with full ownership transferred upon installation. The program will serve approximately 976 low-income homes across Colorado’s 64 counties. Due to limited funds, income qualification alone does not guarantee participation in the program. Read more about eligibility in the Information for Coloradans section.
The Request For Applications (RFA) for public and/or nonprofit weatherization providers to administer SF100 is now open! Applications close October 10, 2025.Learn more about the Single Family 100% Subsidy Program
