EnergySage is a clean-energy marketplace that helps homeowners explore, compare, and purchase solutions for their homes. Its platform connects customers with pre-screened, certified installers and makes it easier to compare quotes, review financing options, and learn about potential savings and incentives. EnergySage offers support for home solar, including guidance on panels, inverters, installation, and buying or leasing. Homeowners can also compare home batteries, assess backup power needs, and explore battery financing and virtual power plant programs.

Beyond solar and storage, the marketplace covers whole-home electrification, high-efficiency heat pumps, electricity plans, and home electrical services. Customers can find electricians and arrange installation of home EV chargers, with guidance on related costs and electrical panel upgrades. EnergySage also provides educational guides, expert research, market reports, news, and customer testimonials to help people make informed decisions. The company says its marketplace was developed with funding from the U.S. Department of Energy and aims to make clean home energy solutions more affordable and accessible.
