Sun Home helps homeowners understand which electrification upgrades make sense first, so the home becomes more efficient before layering in solar and storage.
Solar & battery storage—after your home is efficient
The smartest way to go solar is to fix energy waste first. Once your home is insulated, weatherized, and electrified, you need fewer panels and can get more value from battery storage.
Sun Home helps you determine when solar and storage make sense—after capturing all available efficiency incentives.
