Are solar calculator results financial advice?

No. All calculator results are estimates for educational and planning purposes only. They are not financial, tax, legal, or investment advice. Always verify important solar decisions with a licensed installer and qualified tax professional before proceeding.

How accurate are SolarToolsOnline calculators?

The calculators use standard industry formulas and are designed to be accurate under typical assumptions. Real-world results may vary due to local utility rate changes, shading, actual panel performance, and other site-specific factors. Use results as a starting point, not a guarantee.
