Desert photovoltaic panel cleaning equipment

How to clean photovoltaic panels in desert zone?

An autonomous robotic device has been developed for the waterless cleaning of photovoltaic panels in desert zone. Two helical brushes with opposite helix angles wipe away sand from the photovoltaic panels. Ultrasonic sensors are used for the real-time adjustment of the position, trajectory and speed rate of the robotic device.

What are the problems with PV power plants in the desert?

PV power plants in the desert areas have to endure severe environmental conditions. One of the most serious issues is a dust settlement (soiling). Dust accumulated on the surface of the PV panel can reduce the power output considerably.

How to clean drone-based solar panels?

Optimum cleaning technique suitable for retrofitting onto drones is determined. Significant reduction in the PV efficiency is observed for monthly cleaning periods. Microfiber based-cloth wiper is the most suitable option for drone-based solar panel cleaning among selected methods.

Are waterless PV cleaning techniques suitable for large-scale solar power plant cleaning?

In this study, various waterless PV cleaning techniques and apparatuses are evaluated based on their suitability for retrofitting into UAVs/Drones to be used in large-scale solar power plant cleaning applications.

Does rain remove dust from PV modules?

Rainfall is considered the most effective natural cleaning method for removing dust deposition from PV surfaces. In Belgium and Switzerland, an experimental study of natural cleaning by rain was carried out to investigate the impact of rainfall on the PV module cleaning [16, 17].

Why are solar PV installations growing in desert regions?

In desert regions, PV installations have been increasing in recent years. Desert in the world which almost covers one-third of the land surface is obviously one of the greatest locations for the deployment of large-scale solar PV power plants to fulfill the electricity demands .
