4 panels in North have shade till about midday. The problem is my building is on a slope lower than my neighbors so the only option i have is to move them upwards which will solved it.

5 panels max it seems on that roof section

String 1 (north) 6x415w (Voc 47.8v Imp 10.56A) String 2 (northerly Western direction) 6× 415 w (same as above) String 3 (northerly Western direction) 5 x 460w (Voc 49.5v Imp 11.05A) String 4 (Same as string 3). There is also an option for the panels on this string to fit a small section on the northern section towards east (nne 10 deg)

Thanks buddy, I forgot to add one more thing. I'm in the process of adding more panels and need some info in terms of how this will impact mppt performance. I currently have 6 panels on the north side (string 1 mppt 1) and 6 panels on on north west side (string 3 mppt 2). These are 415w panels. I managed to source 460w panels and plan to shift the current string 3 to string 2 so that the 415w panels are on the same mppt. Likewise the 460w will be split into 5s in string 3 and 4 each. How will this impact the performace of mppt 1 that has string 1 and 2 facing different directions or is it not an issue? Similarly with string 3 and 4. Thanks

Never heard of a solar optimizer. I'm planning on adding more panels to compensate for this low production in winter. With regards to the sunsynk 8kw inverter, what happens when you exceed the Ac load? My installer never add my geyser (150l with 3kw element) to the inverter fearing that I may damage the inverter. How true is this? Also has anybody tried mounting those solar trackers (single or dual axis type) for better solar efficiency? I have some concrete roof which I think this may work well with. Any thoughts?

Thanks. Now I don't feel so bad. Your maximum efficiency is close to mines as well.

So you saying I can overspec on panels to compensate for the lower efficiency in my case? Its such a pleasure to have full time power in this city which is constantly plagued with outages.

Thanks for this info.

Western roof. No shade on this one.

Northern Roof. With the sun angle changing, my neighbors carport is causing some shading for half the day. Seems like I need to shift those panels higher.

Thanks guys. Will send the pics later when I'm up there. Yes its dual Mppt inverter (sunsynk 8kw) with each set on each. The panels are arranged in series on each.

Good day all, Just need some advice on my solar setup which was installed recently in the Pietermaritzburg Kzn region. I have 6 panels (415w each) mounted on my north side roof and 6 panels (415w each) on the westerly side closer to north. Now the issue I found is that I am not receiving the total possible production from this setup. In fact the total I noticed was 3.5kw which is a good 1.5kw roughly shy. Is this seasonal related because the sun is shining well these days however the angle of the sun has altered itself as oppose to summer? If you guys have some recommendations let me know. Thanks
