  • Method and apparatus for estimating generated energy of solar cell
    Patent number: 6278954
    Abstract: The temperature correction coefficient in a formula for estimating the generated energy of a solar cell is corrected in the negative direction as the mean monthly ambient temperature increases. For an amorphous silicon solar cell, the generated energy is expected to be smaller than the actually generated energy. To prevent this, a correction coefficient which increases as the mean monthly ambient temperature becomes high is calculated on the basis of the mean monthly temperature at the solar cell installation site. The generated energy is estimated from the mean solar radiation at the installation site, the calculated correction coefficient, and the rated power of the solar cell. With this arrangement, the generated energy of an amorphous silicon solar cell or a photovoltaic power generation apparatus can be more accurately estimated on the basis of the installation site.
