Innovative Low Cost Cleaning Technique for PV Modules on Solar Tracker

This paper presents an innovative low cost cleaning technique for photovoltaic panels on a bi-axial solar tracking system from Helioslite. This competitive solution exploits the motion of the tracker and the gravity effect. The cleaning tests were carried out and validated using an optimal design of the cleaning system prototype. These have been achieved using a locally developed prototype of the Helioslite bi-axial tracker. As a perspective and before proceeding to the realization of the cleaning system in real dimensions, other tests should be conducted in order to ensure the effectiveness of this innovative cleaning system.
