I can see why someone would think a plant‑based coating could smooth out the current. The idea is that the coating would add a dielectric layer that reduces surface conductivity and maybe dampens micro‑sparks. But I’d want to measure its breakdown voltage, its moisture absorption over time, and how it affects the panel’s impedance. If the coating starts to hold charge or leaches ions, you could end up with new voltage spikes. So the concept is not dead in the water, but it needs a full waveform analysis and long‑term field data before I’d trust it to protect the panels.

Got it. First step: measure the coating’s dielectric constant at 1 kHz, then check its breakdown voltage up to 1.5 kV under humidity cycling. Next, track surface resistance every month for two years in a sunny, damp environment, and run an XRF sweep for any ion leaching. Log every waveform, every drift, and only then will I let the panels feel the “happy” effect of a plant layer.
