Optimisation of PV Cleaning Practices: Comparison Between Performance Based and Periodic Based Approaches by ALHAJERI, RASHED ABDULLA

“…Although the biggest costs involved in this technology is the installation/capital costs, the subsequent running costs (although less than traditional sources of energy) such as cleaning and maintenance can increase or decrease the feasibility of these panels. Soiling, which is the deposition of materials (usually dust) that obstruct solar radiation falling on the panel and is one of the major factors of production losses in PV panels, and thus managing it will result in a positive economic and technical impact on PV plant feasibility. …”

Performance of Monofacial and Bifacial Silicon Heterojunction Modules under Desert Conditions and the Impact of PV Soiling by Amir A. Abdallah (11183642)

“…Moreover, the bifacial module was found to be less sensitive to the PV soiling than the monofacial module. The results showed that the frequency of module cleaning could be reduced for the bifacial module compared with the monofacial module, resulting in a remarkable decrease in the module cleaning cost and PV site Operation and Maintenance cost.…”
