Solar Panel Output Calculator
Estimate solar panel energy output from panel wattage, panel count, peak sun hours, and system efficiency.
Frequently Asked Questions
What are peak sun hours?
Peak sun hours (PSH) are the equivalent hours of full sunlight a location receives per day. Typical planning values are often around 3 to 6 hours.
What does efficiency include?
Efficiency can represent wiring, inverter, temperature, soiling, and other system losses. Adjust it for your planning assumptions.
Is this accurate for my location?
No. Results are estimates only. Actual output depends on location, orientation, shading, weather, inverter clipping, and installation details.
