How It Works
Shading has a disproportionate effect on solar panels because panels in a string are limited by their weakest cell. Even 10% physical shading can cause 25-35% output loss with traditional string inverters. Power optimizers or microinverters isolate each panel so shading only affects the shaded panel, reducing losses to roughly 1:1 with the shaded area.
