hi - have got quotes for 6.6kw solar (18 panels) - our consumption 20-25kwh per day. looking for value for money soln. On my north facing, pool heating is there so combination of west and east was considered as suitable location for panels. However, on my west roof, half the roof is shaded due to tree next to the house. The shading doesnt has much bearing in summer however will likely have material impact in winter/autumn including some on east side.
Two installers I spoke to suggested going for solar edge or optimisers to provide for the shading. I was thinking of having two separate strings so that the panels on the east can generate in the morning and the panels on west in the afternoon.
After reading the blog on solar edge - requiring minimum 6 panels not to be in shade - am not sure my above configuration of 2 separate strings for east and west works.
Open to suggestions on layout of panels and whether solar edge/enphase/tigo optimiser will work better.
