Original Abstract

This paper presents results of analyses of the polycrystalline silicon photovoltaic modules with phenomenon emerging recent years on the surface of cells working at least one half of year in duty called as Snail tracks or Snail trails typical by optical color changing on surface in accident shape like trails made by snails. We have undergone these modules extensive testing and analyses. The output operation performed in laboratory by flash tester and also in situ on operation field reveals no significant drop in wattage, and the drop exhibited by a very small number of modules was due to cell breakages in some cases corresponding with the shape of snail trails. We have also focused on thermal analyses of modules which we are bringing in this article.
