This paper discusses the application of flat panel reflectors in conjunction with photovoltaic cell used to power wireless sensor node. The aim of the reflectors is to increase the indoor ambient light energy harvesting efficiency, especially under low illumination levels (<200 lx). The benefit of the reflectors usage is in the reduction of the node cold boot time and increase of the data transmission...
Tracking the maximum power point (MPP) of a photovoltaic array is an essential part of a photovoltaic (PV) system. PV system performance average losses are of about 20%-25% in electricity production. The causes are mismatching losses, partial shadows, variations in current - voltage characteristics of PV modules due to manufacturing processes, differences in the orientations and inclinations of solar...
