Abstract

AbstractEfficiency of solar PV system decreases due to factors like dust accumulation and bird dropping which limit its performance by lowering the transmissivity. This decrement in efficiency is significant and can be observed in large arrays used for commercial purpose. In order to solve this problem of efficiency decrement, removal of these materials is necessary on regular basis. Many types of cleaning mechanisms are available to clean the solar panels in commercial applications; however, there is need for a more affordable system for residential applications. In this regard, work is taken up to design and simulate the structural components of an automatic solar PV panel cleaning mechanism which is structurally stable, durable and affordable for cleaning of residential PV panels. The system is designed in SOLIDWORKS to analyze its working process properly, and the components are designed and simulated in ANSYS workbench separately. The analysis mainly covers the threaded rod and rubber wiper, and the total torque requirement for the system has been estimated. This solar PV panel cleaning mechanism can be programmed with microcontroller and dust detecting sensor to make the system fully automatic.KeywordsPV panel cleaning mechanismDust cleaning mechanismStructural componentsThreaded rodSOLIDWORKSANSYS
