How our content is created

Our guides are researched from manufacturer specifications, published industry pricing data, utility and permitting publications, and licensed-contractor sourced input where available. Content is written in plain language and reviewed for accuracy before publishing.

How we evaluate sources

We prioritize primary sources — generator manufacturers, code and permitting bodies, and utility companies — over secondary aggregation. Where cost or timeline figures come from industry-wide averages rather than a specific verified project, we say so.

Prices are estimates

Any price range shown on this site is an estimate for general planning purposes, not a quote. Real project costs vary by equipment choice, home electrical panel condition, site accessibility, and local labor rates.

Permits and requirements vary

Electrical and generator permit requirements differ by state, county, and utility provider. Always confirm current requirements with your local permitting office and utility company before starting work.

Verify contractor credentials

We encourage every homeowner to independently verify a contractor's license, insurance, and standing with their state licensing board before signing any agreement.
