Abstract

The invention relates to the technical field of solar cells, and in particular relates to a power testing method and system for a special-shaped solar cell module. The method comprises the steps of obtaining the measurement power of the special-shaped solar cell module and a planar solar cell module corresponding to a plurality of light incident angles; calculating to obtain average measurement power of the special-shaped solar cell module and the planar solar cell module; acquiring measurement power of the special-shaped solar cell module and the planar solar cell module corresponding to a preset light incident angle; calculating conversion power by utilizing the average measurement power of the planar solar cell module, the special-shaped solar cell module corresponding to the preset light incident angle and the measurement power of the planar solar cell module; calculating a power attenuation coefficient; and calculating the actual power of the special-shaped solar cell module by using the power attenuation coefficient. According to the method, the correction of the measured power of the special-shaped solar cell module is realized, and the accuracy of the measured power is improved.

Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a power testing method and system for special-shaped solar cell components. Background technique [0002] With the continuous development of science and technology, the demand for energy has increased, and energy depletion has become increasingly prominent. New energy has become a global research hotspot. Photovoltaic power generation has become the most popular green energy due to its non-environmental pollution and inexhaustible supply. [0003] Among them, the most important part in solar power generation is a solar cell module, which is used to convert solar energy into electrical energy. Therefore, the I-V characteristic of the solar cell module is particularly important, and the I-V characteristic of the solar cell module needs to be tested before leaving the factory to calibrate the power of the solar cell module. [0004] In the prior art, I-V testing equipment is g...
