[QUOTE="bladerunnerpv, post: 551842, member: 35385"] Had a bit of free time recently to play with easy-pv 3D, so put together my house situ. As you can see (1st pic) , not the clearest of surroundings. (mine is the one with the red gable end and panels on the roof - gable end is approx S-facing, tall trees are to the west) The roof lines to the south are not so bad, The real irritation is the deciduous tall trees to the west which have an impact. I reckon about 1/2 hr sunlight lost in mid October (see pix, roof ones are west-facing), but it also affects the summer as the sun transits much of the way across them, interrupting some evening generation, maybe 1-2hrs In your experience of shading does this shading from trees look like a case where I'd really need and benefit from solar optimisers or enphase micro optimisers? Or is it more likely not to be cost-effective, with Enphase at £150ea that's £1500 vs a £500 solis PV inverter, so it would need to regain £1000 over 10yrs to make it worthwhile, unless there was another benefit like making panel changes easier, or facilitating addition of 6x south facing panels at a later date thanks for taking a look [/QUOTE]
