Fine Print and Sources
Screening estimate only. These tools use only the values you enter and simple planning math. A licensed electrician or battery installer is authoritative for final capacity, backup panel design, and installation. Confirm the numbers with a professional and get written quotes.
This is an estimate, not a quote. Get written quotes from installers and confirm current incentives at the source. The federal residential clean energy credit rules changed after 2025, so do not assume a percentage applies to a battery placed in service today. Check the IRS page, DSIRE, and your utility.
