During the winter seasons, there is not only the challenge of removing snow downfall on PV solar cell roofs in order to maximize the solar energy efficiency, but it is also to indicate when the effect of snow significantly affects the operation in order to decide to take an action. Up to know, the study of the optical properties of snow have been examined, including shading patterns on photovoltaic solar panels. However, while the snow cover might reduce electricity, it might not have been significant effect due to the lack of solar radiation in the Nordic countries. In this paper, the authors have focused to propose an experimental methodology to analyze the effect of the thickness of the snow on a PV regulator response based on the frequency, statistical and production analyses in a simple PV solar cell module. In order to study the effect of the electrical production in relation to the thickness of the snow and light conditions, a set of experiments were proposed with the LEGO® PV system.
