Electricity bills are used to estimate the potential savings from solar energy, and Energy Sage has been found to offer customers substantial savings over more conventional products. Users can comparison shop and select the system that fits their needs best.
EnergySageĮnergySage, a previous Incubator awardee, allows homeowners, businesses, or nonprofit organizations to estimate their energy savings from solar, and connects them with prescreened installers who can provide estimates specific to the user’s address.
