Terms of Service

Last updated 2026-07-08

Acceptance of terms

By accessing or using SolarToolsPro (the "Site"), you agree to be bound by these Terms of Service. If you do not agree with any part of these terms, you should not use the Site.

Description of service

SolarToolsPro provides free, browser-based calculators for home energy, solar, EV charging, battery storage, and related topics. All calculations are performed locally in your browser using JavaScript. The Site does not require registration, does not store your inputs, and does not transmit calculator data to any server.

No professional advice

The calculators and content on SolarToolsPro are provided for informational and educational purposes only. They are not a substitute for professional advice from a licensed electrician, solar installer, energy auditor, financial advisor, or tax professional.

Calculator results are estimates based on generalized assumptions and the inputs you provide. Actual energy production, savings, payback periods, and equipment performance will vary based on factors the calculators cannot fully account for, including but not limited to:

  • Local weather patterns and microclimates
  • Roof orientation, tilt, and shading
  • Equipment manufacturer tolerances and real-world performance
  • Utility rate changes and net metering policy changes
  • Installation quality and workmanship
  • Appliance duty cycles and usage patterns
  • Future electricity price inflation

Accuracy disclaimer

While we strive to keep the calculations, formulas, and reference data accurate and current, we make no warranties or representations regarding accuracy, completeness, or timeliness. The appliance wattage values, electricity rates, and solar panel specifications in our databases are typical values drawn from publicly available sources and may not reflect your specific equipment or local conditions.

Always verify calculator results against multiple sources and consult a qualified professional before making purchasing decisions based on these calculations.

You agree to use SolarToolsPro only for lawful purposes. You agree not to:

  • Use the Site in any way that violates applicable laws or regulations
