Solar & Battery Guide Editorial Team
Our editorial team researches home solar, batteries, utility rules and incentives from primary sources such as the IRS, DOE, NREL, EIA and state utility regulators.
Articles and calculators on this site are written and checked by the Solar & Battery Guide editorial team. We do not install or sell solar, and we do not accept payment from installers or lenders for coverage. Every guide lists the official sources it relies on with the date we checked them, and every calculator shows its formula and assumptions. When rules change, as the federal residential credit did at the end of 2025, we update the affected pages and note the change. Read our editorial policy and methodology for details. Named expert reviewers will be listed here when they join.
