How to handle partial shading on panels in a patio setup?

Minimizing the impact of partial shading on small solar arrays

Partial shading reduces output and can create disproportionate losses if panels are wired in series. Design and equipment choices mitigate these effects.

Mitigation strategies:

• Use microinverters or power optimizers that allow each panel to operate independently
• Arrange panels to minimize shading from surrounding structures or plants
• Choose panels with good shade tolerance and bypass diodes

Reorient panels where feasible and trim nearby vegetation. For modular patio setups, place panels with the cleanest sun exposure individually wired to maximize combined output.
