Disclaimer

PV Yield is an informational calculator. It does not guarantee project performance or investment return.

Solar project outcomes depend on site-specific conditions including shading, module orientation, roof structure, utility rules, tariffs, incentives, permits, metering, equipment selection, installation quality, maintenance, tax treatment, financing terms, and weather variability.

The calculator output is not financial advice, legal advice, tax advice, engineering advice, or an offer to buy or sell any product or service. Users should verify assumptions with qualified local professionals before making decisions.

Weather and geocoding data can be incomplete, delayed, or different from actual site measurements. Tariff defaults are estimates and may not reflect a current utility contract.

Use results as a screening estimate

PV Yield is best used to decide whether a project deserves deeper review. A positive payback or IRR result does not guarantee that a project can be built, connected, insured, financed, or approved by a utility. A weak result can also improve after a better quote, higher self-consumption, revised tariff, storage strategy, or incentive review.

Check local assumptions

Before relying on any output, confirm the project address, roof or land constraints, annual load profile, meter type, export rules, tax treatment, maintenance plan, equipment warranty, inverter replacement risk, and local safety requirements. The calculator cannot inspect a site or know contract-specific conditions.

Users should also compare PV Yield results with installer production estimates and utility documents. Differences are useful because they reveal assumptions that need review, such as weather source, loss rate, tariff credit, annual degradation, or whether costs include permitting and grid connection.
