| Popis: | 28th European Photovoltaic Solar Energy Conference and Exhibition; 258-262 The SPF certificate “solar glass” was developed in 2002 to guarantee the quality of glazing for the use as transparent cover for solar thermal collectors. More than 200 glass types of the leading manufacturers have been measured and certified in the following years. Although it was explicitly developed for solar thermal applications, it became widely used in the pv-module industry, as well. Therefore, this certificate was adapted recently to the special properties of crystalline solar cells, which are directly laminated onto the glass resulting in a specialized certificate for pv-applications. For the certification different factors are defined in order to classify the tested glass in several performance groups. These are: a) transmittance factor, b) incident angle modification factor and c) photo-degradation factor. The product of these performance factors results in one characteristic number: the glass efficiency factor (GL_PV), giving the influence of the tested glass to the annual electricity production for a typical PV-plant in central Europe (c-Si cells, 30° inclined, south oriented). This factor was determined for several flat and structured glass types with and without antireflective coating. |
