What is this calculator?
Estimate daily panel energy from capacity and effective sunlight.
What can you use it for?
Use it for practical planning, conversions, measurement or checking the result described here. Estimate daily panel energy from capacity and effective sunlight.
How to use it
- Enter panel capacity (kw).
- Enter peak sun hours per day.
- Enter system yield factor (%).
- Select Calculate (or Generate for random tools).
- Read the answer and any additional results below the form. Check the units and the limits of the method.
Formula and method
The formula uses the units and definitions shown above. Each input is substituted before the arithmetic is evaluated; the calculated output is rounded for display.
Worked example
Panel capacity (kW): 5, Peak sun hours per day: 5, System yield factor (%): 80. The result is 20 kWh/day (result).
Assumptions and limits
User-entered sunlight and system losses. No location weather forecast.
