How does shading affect solar panel performance, and how can it be minimized?

Shading can significantly reduce the performance of solar panels. Because PV cells are connected in series, shading on a single cell can lower the output of the entire string. It may also lead to hot spots, which can affect panel durability over time.

To minimize these effects, systems can incorporate technologies such as bypass diodes, microinverters, or power optimizers, which help reduce energy loss and improve system monitoring.
