Solar performance results under trees

[justinm001]

I live in the woods in Ohio and currently no leaves. On my RV I have 18x100w panels, 3x100w in series to my 12V and 5s3p 1500w to my 48v. I'm noticing about a 20% increase in performance in the series vs parallel when under shading. On days when I'm on the road and parked usually under clear sun I'm noticing 17% increase in the 48v system. 8.64kwh vs 1.48kwh (multiplied by 5 7.4kwh). This seems a bit confusing and once I get more results over multiple trips and longer days parked in full sun I'll know more.

The plan was to add more panels while at home in a ground array and utilize my inverter system in the coach to backfeed into my house using ESS and offset some of my home's monthly 3000kwh usage, then unplug and still use like normal on the road. It seems that the solar isn't even close to covering the RVs idle loads.

Any tips on how to setup solar under trees for optimal performance?

Are you factoring in shading associated with roof protrusions, i.e., your 1000 A/C units?

They're above the A/C units and everything else angled slightly facing the sun. Now its warming up I plan on replacing these panels with larger ones I have laying around and finishing both sides angled opposite to eachother.

I get the 20% loss in parallel but I'm surprised in the gain when full sun but could be something else like angle or even charge level or alternator charging while driving. Hopefully I'll have more results and better comparisons just hard to get concrete numbers when I use it 1-2 times a week and random places. Plus the VEdirect cable keeps popping off the 12V MPPT... so some superglue is in order

Hopefully I'll also have the 1000w trailer hooked up soon, just need to figure out where to put everything
