Planning estimates, not guarantees
Every calculator on Solar Metrix produces a planning estimate. It is built from the numbers you enter, historical weather data and labelled assumptions. It is not a measurement of your roof, a quote from an installer, a structural certificate or a promise that a system will produce a particular amount of energy.
Actual results can differ materially because of shading, dust, soiling, module quality, inverter efficiency, cable losses, installation workmanship, equipment failure, grid outages, weather, temperature, tariff changes and how you use electricity.
No financial or investment advice
Payback, ROI, battery economics, loan and EV comparisons are educational models. They are not financial advice, an investment recommendation, a credit decision or a guarantee of savings. Tariffs, subsidies, net-metering rules, taxes, financing costs and equipment prices can change after you run a calculation.
Before borrowing money or signing a solar contract, confirm the figures with your lender, a qualified financial adviser and the installer. A payback that looks attractive with one tariff assumption may be unattractive with another.
No engineering or safety certification
Roof space, string sizing and battery backup results are preliminary planning outputs. They do not confirm structural capacity, wind loading, waterproofing, fire setbacks, cable ampacity, breaker ratings, earthing, inverter compatibility or grid-code compliance.
Do not use a calculator result as an installation instruction. A qualified engineer or licensed installer must approve the structural, electrical and safety design for your property and your local code.
Data and third-party sources
Weather, geocoding, map and analytics data come from third-party providers. We do not control their accuracy, coverage or availability. A weather dataset is a historical record, not a forecast. A geocoder may return a nearby point rather than your exact roof. If a lookup fails, the calculator may fall back to a regional or latitude-based estimate, and it will say so where possible.
Where a calculator uses a default assumption — for example system losses, soiling, battery efficiency or tariff escalation — the default is a planning value, not a measurement. Replace it with your own datasheet or bill value when you have one.
External links and installer listings
Links to installers, manufacturers, map providers, payment brokers and AI tools are provided for convenience. A listing or link is not an endorsement, certification or guarantee. We do not control the content, pricing, availability or privacy practices of those third parties. Check their credentials and terms before sharing data or money.
Accuracy and corrections
We try to keep formulas, assumptions and references accurate, but errors are possible. If you believe a result is wrong, email privacy@solarmetrix.app with the page URL and the inputs you used. We review credible reports and update the page when a correction is warranted.
Limitation of liability
To the fullest extent permitted by law, Solar Metrix is not liable for loss or damage arising from reliance on a calculator result, a guide, an installer listing or a third-party link. You use the site at your own risk and remain responsible for your own decisions. Nothing in this Disclaimer excludes liability that cannot lawfully be excluded.
