What this site does
SolarStateData turns scattered public information into practical state guides, cost estimates, and product research for US homeowners. The aim is to make the financial trade-offs clear before anyone talks to an installer or buys backup-power equipment.
Sources and method
State and market pages use sources such as DSIRE, the US Energy Information Administration, NREL, state public-utility commissions, tax authorities, manufacturers, and published market datasets. Each page identifies its source set and update date.
Figures are estimates, not quotes. Incentives and utility tariffs change, so readers should confirm eligibility with the programme administrator before making a purchase.
Commercial model
Some clearly marked product links are affiliate links. SolarStateData may earn a commission when a reader makes a purchase, at no extra cost to the reader. Commercial relationships do not guarantee inclusion or a positive assessment.
Unless a page explicitly says otherwise, product analysis is based on specifications, documentation, warranty terms, pricing, and owner feedback, not claimed first-hand testing.
