Even though the house is facing South, the 8 x 100 watts panels are not producing that much power early morning and late afternoons. During winter months the output was around 500-700 watts most sunny days. The average daily power output hovered around 3.5-4 kW daily. Now that the summer is coming and the sun is higher I noticed 2-3 panes are getting partially shaded in the early mornings and late afternoons and the power is dropping dramatically to 120-150, why is there such a high drop? There are 2 arrays of 4 panels each in series/parallel going to a Victron charge controller, shading happens on 2-3 panels on the top array closer to the house (back porch) facing south early mornings and late afternoons so at least 5 panels are not shaded . I could move the panels but they are pretty much out of the way where they are. Shouldn't the output be higher, maybe around 300-400? I can understand that the sun movement during the day will affect output but I don't think it should be so low while 5 panels are getting full sun light, the shading is partial I would guesstimate 15% on each panel. Could the shaded panels be bringing the output that low?
