Description

Technical Field

[0001] This utility model relates to the field of photovoltaic testing equipment technology, specifically a performance testing device for a farm photovoltaic system. Background Technology

[0002] Farm photovoltaic systems integrate solar photovoltaic systems with planting and animal husbandry on a farm, providing low-cost power generation for the farm's production and operation. Due to the farm environment, photovoltaic panels are easily shaded by some plants or blocked by fallen leaves, causing some cells to malfunction. This results in uneven heating of the photovoltaic panel surface, and excessive temperature differences can cause some panels to burn out, producing dark spots, which in turn affects the lifespan and conversion efficiency of the photovoltaic panels.

[0003] Therefore, in farms with abundant vegetation, it is necessary to frequently inspect the photovoltaic panels to promptly identify and remove any obstructions. Performance testing is also required to locate and repair any damaged panels.
