Estimates only — not a quote. The figures produced by this calculator are preliminary estimates generated from the limited inputs you provide and general assumptions. They are not an engineered proposal, a price quote, a guarantee of savings or tax-credit value, or a commitment of any kind. Actual system size, costs, savings, incentives, and tax outcomes depend on a detailed site assessment, your utility rate structure, your organization's tax position, and applicable federal and state rules, which change over time.
Tax credit, safe-harbor, and incentive figures are illustrative and depend on your eligibility and circumstances. Better Tomorrow Solar does not provide tax, legal, or financial advice; consult your own qualified advisors. A binding scope, pricing, and any deposit or escrow terms are established only through a separate written agreement following an engineering review. † A note on units: “ton” throughout this calculator refers to a metric ton (1,000 kg / 2,204.62 lbs) — the standard unit used by the EU carbon market and in every calculation here. It is heavier than a US short ton (2,000 lbs).
