Method for detecting the degree of soiling of PV modules |
摘要 |
A method for detecting the degree of soiling of PV modules of a string comprises the following steps: determination of the deviations of the string power output values from a calculated reference value over the last year; calculation of a historical trend line from the deviations; determination of a maximum difference between the trend line and the deviations; calculation of final deviations of the power output values through subtraction of the maximum difference from the trend line; and determination of the degree of soiling through subtraction of the final deviations from the deviations. |
