What SolarSizr provides

SolarSizr offers free online calculators and related information for planning DIY and off-grid solar systems. The calculators run in your browser and are provided for general informational purposes only.

Estimates, not professional advice

All results are planning estimates based on standard, published formulas. They are not engineering, electrical, or professional advice, and they do not replace local electrical codes, product specifications, or the judgment of a licensed electrician or installer. You are responsible for verifying any figure before you buy equipment or build a system. Incorrect wiring, fusing, or sizing can be dangerous.

No warranty

The Site and its calculators are provided "as is" and "as available", without warranties of any kind, express or implied, including accuracy, fitness for a particular purpose, or uninterrupted availability. We do not guarantee that results are error-free or suitable for your specific situation.

To the fullest extent permitted by law, SolarSizr and its operator are not liable for any loss, damage, injury, or cost arising from your use of, or reliance on, the Site or its calculators. Your use of the Site is at your own risk.
