- Enter the System efficiency.
- Click Calculate Result to compute the final value.
Formula / Calculation Method
The mathematical operation applied is:
Result = kwh/30,kw=daily/(sun*(eff/100))
Worked Example
Calculation scenario based on standard inputs:
Inputs:
- Monthly energy use: 10 kWh
- Peak sun hours / day: 10 hours
- System efficiency: 10 %
Calculated Result:
- Main Result: 0.33 kW
- Daily energy target: 0.33 kWh
- Recommended system: 0.33 kW
Understanding the Result
The result estimates system performance or sizing. Real-world efficiency is influenced by physical variables such as friction, shading, temperature, and wear-and-tear.
Common Use Cases
- Sizing hardware for a new installation or purchase.
- Estimating payback periods and operational fuel/energy costs.
