The Importance of a PV System Washing Program

For the owners of these installations, it is important to ensure that they can capture as much of the sun's energy as possible. In desert conditions and locations close to open land, exposure to the environment creates dust and pollen depositions on the PV panels that degrade the efficiency and energy production of solar systems. Infrequent rain precipitation prolongs this undesirable condition. PV modules produce the most energy when regularly cleaned. The economic impact of dirty PV modules could be particularly significant during the summer season of peak production capability. Impact of PV System Washing Meaningful improvements in the PV performance at four sites were recently noticed after modules washing. The table below shows increased measured efficiency varying from 9 percent to 26 percent. These improvements would be the same for commercial or residential project...
