Build a conservative planning estimate for system cost, tax-credit eligibility, depreciation value, and payback. Final economics require a site, utility bill, tariff, and tax review.
Commercial solar is modeled at $1.10-2.55/W before project-specific incentives. This planning calculator starts with no bonus eligibility selected and lets a user add prevailing-wage and domestic-content eligibility only when the project can document those requirements. It uses state-average rates and tax assumptions, so the result is not a quote, guaranteed savings figure, or statement of cash required at installation.
Start with conservative eligibility assumptions, then select only the tax-credit requirements your project can document.

This calculator provides a preliminary planning estimate based on average pricing, production, state electricity rates, and tax assumptions for 2026. It is not a quote. A decision-grade analysis requires the site's utility bill and tariff, usable roof or land, structural conditions, interconnection scope, financing, and documented incentive eligibility.
