Method:
Recovered energy = current daily generation × entered soiling loss.
Monthly and annual values are calculated using the electricity value entered above.
If a cleaning cost is provided, simple payback compares that cost with the estimated monthly value of recovered generation.
This is an estimate. Actual cleaning benefit depends on how dirty the panels are, rainfall, tilt, cleaning effectiveness and how quickly soiling returns.
