Development of low power laser in-situ thickness measurement for correlating the dust thickness to the PV performance

Maintaining the photovoltaic (PV) panels operating at their optimum performance is a critical objective for energy harvesting. However, dust deposition due to natural, vehicular, and construction work over a period on the panels reduces the performance of the system. The primary goal of this work is...
