Method and equipment for measuring and monitoring optical performance degradation in photovoltaic cells due to water accumulation.

摘要

The invention provides a method and device for measuring and monitoring the fouling rate of a plate photovoltaic power plant: FIX or mounted on a uniaxial solar tracking system. The invention can also be measured and measured.Comparison Ratio: Optical properties of concrete and different types of photovoltaic glass, whether coated or not. The invention consists of two metal boxes with the smallest number, in which each pair of metal boxes must have the same quantity.1. For a pair of pyran anodes with the smallest two pyran anodes, the torque of each pair of pyran anodes must be the same; for a pair of photovoltaic glasses with the smallest two, the torque of each pair of photovoltaic glasses must be the same; E Inclination change crank. The invention uses the sun as a light source.
