“…As they proposed weekly cleaning for PV modules in the steppe climate, there is a timetable for cleaning the power station modules by the use of weekly water jets. Using the excellent guidance of Mani and Pillai will prevent and mitigate the effect of soiling on the PV modules [9,31].…”

“…In comparison to soiling rate studies, there are only a few scientific reports on common cleaning economics and costs with regard to PV soiling. 9,22,51,[115][116][117][118][119][120][121][122][123][124][125][126] The outcomes of these studies are difficult to compare, as they mostly report on soiling economics for a particular site (sometimes without optimization), use complex model approaches that are not easy to reproduce or are based on limited or outdated data. Therefore, information on cleaning costs has been compiled from industry partners and stakeholders, indicating huge differences between the different countries and different sites and plant sizes (see Figure 2C).…”

Soiling consists of the deposition of contaminants onto photovoltaic (PV) modules or mirrors and tubes of concentrated solar power systems (CSPs). It often results in a drastic reduction of power generation, which potentially renders an installation economically unviable and therefore must be mitigated. On the other hand, the corresponding costs for cleaning can significantly increase the price of energy generated. In this work, the importance of soiling is assessed for the global PV and CSP key markets. Even in optimized cleaning scenarios, soiling reduces the current global solar power production by at least 3%-4%, with at least 3-5 billion V annual revenue losses, which could rise to 4%-7%, and more than 4-7 billion V losses, in 2023. Therefore, taking into account the underlying physics of natural soiling processes and the regional cleaning costs, a techno-economic assessment of current and proposed soiling mitigation strategies such as innovative coating materials is presented. Accordingly, the research and development needs and challenges in addressing soiling are discussed.

“…In a different approach, the levelised cost of energy (LCoE) was used to evaluate the cleaning cycle of thin film and monocrystalline collectors in a coastal region in Chile [28]. The result indicated that an annual rate of 12 times increased the performance rate by 8% in comparison to three times annually thereby obtaining an improved LCoE of $0.011/kWp from $0.1556/kWp.…”

The effect of installation azimuth angle in the optimization of the cleaning cycle of a solar photovoltaic plant was experimentally investigated in this study. The optimum cleaning cycle was determined using Particle Swarm Optimization algorithm cognizance of the fact that different orientations have different soiling rates. Soiling rates on three different azimuth configurations were experimentally investigated and an exponential soiling loss model was developed for each configuration for use in the optimization problem. Azimuth angle differences of ±12.5% were found to have a significant influence on soiling of as much as 28.29% for the selected location. The North of North West configuration was found to be optimal as opposed to the generally accepted North configuration for maximum energy generation at a minimum cost of energy. This configuration generated 0.87% more energy at unit energy cost of $0.093 compared to the North configuration which had a minimum cost of $0.113. The optimized cleaning cycles were 35 days for the optimal configuration while the North configuration had an optimized cleaning cycle of 28 days. A 17.7% difference in the cost of energy was recorded due the influence of soiling. The study revealed that for minimizing the unit energy cost, it is necessary to take into effect the influence of soiling.
