Theoretical Limits of Internal Shading Effect on Electricity Production of Rooftop PV Plants
Original language description
This paper deals with a problem of internal shading within roof-top PV plants based on c-Si technology. The internal shading results from limited spacing between parallel rows of PV modules and represents the situation when a row of modules is shaded bythe previous one. A procedure to determine theoretical limits of internal shading effect for a typical roof-top PV plant is presented. The procedure is based on the concept of average clear sky day specified for every month, for which a difference in daily electricity production between shaded and unshaded module is calculated. Finally, knowing the monthly distribution of equivalent clear sky days, the effect of internal shading is determined.
