Affiliate Disclosure

NorthSolarCalc links out to EnergySage, a solar installer quote-comparison marketplace, from the calculator and several region pages. We have no referral partnership, affiliate agreement, or commercial relationship of any kind with EnergySage (or with any other company), and we have not registered as a publisher on Impact.com or any other affiliate platform. Clicking through those links earns NorthSolarCalc no commission.

We link to EnergySage because it is a well-known, free-to-use marketplace for comparing solar quotes — a useful next step for readers who want real, local quotes. We would link to it either way; no commercial relationship guarantees or influences the recommendation.

Our calculator's numbers (system size, gross cost, incentives, payback, savings) are computed the same way for every state and province — see our methodology. We do not accept payment from any installer or marketplace to alter their standing, visibility, or the figures shown to you.

The only revenue this site currently earns is display advertising (Google AdSense), once approved. If that ever changes — for example, if we enter a referral arrangement in the future — we will update this page and label the affected links before it takes effect.
