Semi-automated cleaning systems help to raise the yields of solar parks, large-scale rooftop installations or solar carports. And that even in regions where water is scarce – as demonstrated by a project in Jordan.
If you want to save on electricity costs – with or without PV – you should first eliminate devices and appliances that use too much of it. These include standby devices, incandescent light bulbs and water heaters.
The results of the annual and other cleaning sessions need to be logged in your installation’s documentation. At the end of the cleaning, you should recalibrate the yield data.
