tecnun Posted November 22, 2021 Share Posted November 22, 2021 Hello,We've been encountering some severe electrical losses in several 1V tracking mode Utility Scale PV farms, where pitch is a little tight (less than 5 m).For instance, at 5,5 m no electrical shading losses are founded, but at 4,9 m we found a huge drop in PR due to >5% electrical shadings. Does it make sense?Could it be due to an incorrect backtracking algorithm? What we would expect is an angle shorten during the morning and during the evening like the simple drawing we are attaching.If we simulate it in 2H instead of 1V there is no such electrical shadings, we attribute it to the bypass diode effect, what we find it cool, but in tracking mode we should not expect it. If the backtracking applies there will be a gaining drop but no so accused as it is reflected now with such a severe electrical drop.Is there some explanation to this effect?Best.
