joey_tribbiani Posted February 1, 2020 Report Share Posted February 1, 2020 I have considerable doubts about calculating the power of the MPPT. In my opinion, the problem exists when there is a shadow on the PV installation. In the pictures below, a situation in which, despite the total shade of the modules, the installation produces about 400 W. Such an anomaly occurs for most of the days I am analyzing. On some days it looks more correct (photo no. 3). I often make comparisons with large shading (about 8%) between systems with and without optimizers and the conclusions from each such comparison are that it is not worth paying more for the system e.g. SE because actually according to your program the differences are small in the annual yield. Please explain why the program is so optimistic about uneven shading of several or even all PV modules. Quote Link to comment Share on other sites More sharing options...
