PV module

The PV module used in the tests is the Solon P160/6, which is produced by the company SOLON Photovoltaik GmbH. The module consists of 50 (5×10) stk. polycrystalline 6” (150×150 mm) cells, [6]. The total solar cell area is 1.125 m2. Figure 1 shows a picture of the PV module used for the experiments.

The total measures of the PV module are 793x1593x5 mm (width x height x thickness) without frame. According to the product information from the manufacturer the rated maximal power of the module, Pmax, moduie, is 160 Wp (±3%), normalized 142 W/m2 under standard test conditions. The efficiency of the cells is 14.2 %, whereas the module efficiency is 12.5%. The front glass is a 4 mm ESG white glass.

First a number of efficiency measurements were carried out with the PV module. Then the outer surface of the glass cover of the PV module was equipped with an antireflection treatment by SunArc A/S. Finally; a number of efficiency measurements were carried out with the PV module with the new glass surface.
