Terms of Service

Last updated: October 19, 2026

By using SmartSolarSizer ("the site", "the calculator"), you agree to these terms. If you don't agree, please don't use the site.

1. What this tool is

SmartSolarSizer is a free, informational calculator that estimates solar panel count, inverter sizing, system cost, and payback period based on figures you enter and standard industry sizing formulas. It is a planning aid, not an engineering design, a quote, or professional advice of any kind.

2. Accuracy disclaimer

Results are estimates only. They rely on typical appliance wattages, standard system-loss assumptions, and the sun-hour, cost, and tariff figures you select or enter — actual results depend on your specific roof, shading, equipment, local regulations, and installer pricing, all of which can differ meaningfully from these estimates. Always confirm final system specifications with a licensed solar installer before purchasing equipment or signing a contract. We make no warranty, express or implied, that the calculator's output is accurate, complete, or fit for any particular purpose.

3. Not professional advice

Nothing on this site constitutes electrical, engineering, financial, or legal advice. Electrical work, including inverter and solar installation, should be carried out by a qualified, licensed professional in accordance with local codes.

4. Third-party installers

SmartSolarSizer does not connect you with installers or share your details with them. If you choose to contact an installer using our results, we don't guarantee the quality, pricing, or availability of any installer, and any agreement you enter into with one is strictly between you and them.

5. Acceptable use

You agree not to misuse the site — including attempting to disrupt its operation, scraping it at a disruptive rate, or using the contact form to send spam or false information.

6. Limitation of liability

To the fullest extent permitted by law, SmartSolarSizer and its operators are not liable for any direct, indirect, incidental, or consequential loss arising from your use of, or reliance on, this site or its calculator results — including any purchasing decision made using the estimates it provides.

7. Changes to the service

We may modify, suspend, or discontinue any part of the site at any time without notice.

8. Changes to these terms

We may update these terms periodically. Continued use of the site after a change constitutes acceptance of the revised terms.

9. Contact
