esmail-kassir Posted September 18 Share Posted September 18 I have 4 x 580W Jinko bifacial panels, and I typically generate around 13 kWh during the day, with a peak of about 1950W. Recently, I’ve noticed very low production after 4:00 PM due to shading from the water tank on the neighboring building’s roof. Lately, I’ve observed a rise in voltage after 6:00 PM. Could this be due to the consistent albedo effect across all panels as the direct sunlight fades? If so, how can I take advantage of this phenomenon? Note #1: You won’t see any production after 6:00 PM on the chart because the grid becomes available, and the inverter switches to grid power. Note #2: you won’t see production if tge battery is becoming full and no loads The situation here is that electricity is cheap but only available for 1 hour and then off for 5 hours, so inverters are usually configured to use utility power when it’s available Quote Link to comment Share on other sites More sharing options...

Mauritius B Posted September 20 Share Posted September 20 The low production due to partial shading can be mitigated with optimizers installed on the affected panels. Quote Link to comment Share on other sites More sharing options...
