Abstract/Summary:


In this paper we present the analysis of the causes that caused the destruction of photovoltaic modules cover glass in the group of modules randomly located in the photovoltaic field. Operator of photovoltaic system excluded the possibility of damage of these modules by impact of foreign objects because of their location in the photovoltaic field and because of no records of hail or similar events in this area. Damage of the cover glass in analyzed module appears to be adequate of safety glass cracking - uneven web of cracks in the glass with six central location with a different structure cracking. In the three of these areas is possible to find the area with the browning of the surface on the photovoltaic cells main contacts. This article also includes summarization of method which is possible to use for analyses of photovoltaic modules state.
