There's basically two kinds of systems.
Micro inverters or mppt with inverters.
With micro inverters you cannot over provision the panels in a useful way, each panel or pair of panels has a micro inverter.
The mppt plus inverter system you absolutely can do that... but it scales poorly. Shading of a single panel effects the entire string, so the more panels you add to over provision the worse that effect gets.
So yes but actually no.
- dv_dt 1y agoIt seems like there should be some intermediary per panel smart bypass circuit for pairing up with mptt architecture for this to keep system cost down in these seasonal areas. Edit: turns out there are products for mptt strings called power optimizers that seem to help with this very thing I hypothesized.. at least one company offering them is SolarEdge
- buckle8017 1y agoThey're almost as expensive as per panel micro inverters. There's no free lunch here.
