Sean HeberMe everyday now that I have solar panels:
Jamie@bigzaphod Tell me about it! This large tree reduces my output on every sunny day during the winter, just when I need it most. The tree is mine, but to fell a mature Ash tree in pursuit of a "green" lifestyle would be absurd.
Andy FletcherYou might consider optimisers on the panels to keep the system working under shading.
Alternatively split the array into short strings to limit the impact of a couple of shaded panels.
@X31Andy @bigzaphod Thanks Andy. I went with the second option. I was negotiating with my DNO for 3 years. So had been monitoring the shading where the proposed shed was to be. There are 54 400W panels, split into 6 strings of 9. 4 strings on the roof, 2 on the front. Split to mitigate a crossing shadow. Shed was built for PV, south facing, 20 degree roof for summer, vertical panels for winter. Just added a post about it :-

Attached: 3 images We fitted solar thermal (hot water) panels when re-roofing in 2006. They've been great and very cost effective. Added solar PV around them in 2011. In 2023, using over 10 years import/export data I calculated the optimum extra PV/batteries needed to satisfy most of our power needs and covered a shed in PV. The shed is south facing with a 20 degree roof. The vertical panels help in winter.
