Method for detecting simulation efficiency of solar photoelectric module

Abstract

The invention provides a method for detecting the simulation efficiency of a solar photoelectric module. The method comprises the steps of measuring the actual power generation efficiency of the solarphotoelectric module under an actual use condition; calculating the optimal power generation efficiency of the solar photoelectric module under the actual use condition according to a formula (A), wherein the formula (A) is as follows: QA=S*(F/1000)*[1-C*(T-TS)]; calculating the efficiency ratio of the actual power generation efficiency to the optimal power generation efficiency of the solar photoelectric module according to a formula (B), wherein the formula (B) is as follows: WA=Q/QA; and correcting the efficiency ratio for different illumination intensities based on a correction table to simulate the power generation efficiency ratio of the solar photoelectric module under a standard test condition, wherein QA is the optimal power generation efficiency under the actual use condition, Sis the rated power, F is the measured illumination intensity, C is the power temperature coefficient, T is the actual temperature, TS is the standard temperature, WA is the efficiency ratio of the actual power generation efficiency to the optimal power generation efficiency of the solar photoelectric module, and Q is the actual power generation efficiency.

Description

technical field [0001] The invention relates to a simulation performance detection method of a solar photoelectric module, in particular to a simulation performance detection method that can obtain test results equivalent to those in the laboratory without dismantling the solar photovoltaic module at the detection site and returning it to a laboratory for testing. Background technique [0002] Energy is an important dependent factor in human life. In the history of human development, it is inevitable to think about how to effectively manage the use of energy at any time. Since the industrial revolution, fossil fuels (i.e. oil) have become the main source of energy for human beings. However, with the gradual depletion of oil resources, extreme climate change caused by the greenhouse effect, and the imbalance of the ecosystem, countries around the world are actively developing alternative energy sources, such as solar energy, wind energy, geothermal energy, hydropower, etc., ...
