EnergySage is a clean-energy marketplace that helps homeowners compare options, connect with qualified professionals, and make informed decisions about electrifying their homes. Its services include comparing quotes from pre-screened solar installers, exploring solar panels and inverters, and reviewing financing choices, incentives, and potential savings. Homeowners can also compare home batteries, request installation quotes, and learn about backup power, battery costs, and virtual power plants.

Beyond solar and storage, EnergySage supports broader home electrification with personalized plans and information about heat pumps, energy efficiency, electricity plans, EV chargers, and other electrical services. The platform offers guides, cost comparisons, market reports, news, and expert research to help customers understand technologies and available options. EnergySage also works with utilities, government entities, trade organizations, corporations, installers, and community programs to expand access to clean-energy solutions.

Its marketplace was developed with funding from the U. S. Department of Energy, with the stated mission of making clean home energy more affordable and accessible
