Calculateur de Solar Panel Output
Estimate daily solar energy from panel watts, sun hours, and system efficiency.
Formula and method
This calculator computes Daily energy directly in your browser without sending data to an external server.
Mathematical formula
- Daily energy:
watts × panels × sun × efficiency ÷ 100 ÷ 1000
Variables and parameters
- Panel watts (watts): default value 400 W.
- Panels (panels): default value 10.
- Sun hours (sun): default value 4.5 h/day.
- System efficiency (efficiency): default value 80 %.
Some formulas are undefined for certain input combinations (such as division by zero or logarithms of non-positive numbers). In those cases the live tool displays an alert instead of NaN.
