“…The severity of the dust problem arises and increases due to the lack of natural cleaning methods like rainfall and shortage of water resources. Cleaning of the PV panels at such huge plants could prove to be costeffective and effort oriented, since it requires huge amounts of water and workforce; on the other hand, it is difficult to find an abundance of clean water in the MENA region countries and some countries in Asia [100].…”

This paper presents a comprehensive review regarding the published work related to the effect of dust on the performance of photovoltaic panels in the Middle East and North Africa region as well as the Far East region. The review thoroughly discusses the problem of dust accumulation on the surface of photovoltaic panels and the severity of the problem. Moreover, a survey of the most advanced cleaning techniques is presented, and their applicability is evaluated. There are plenty of techniques that have been used to remove the dust accumulated on the surface of PV panels, and these include manual and self-cleaning methods. However, it is concluded from the presented review that there is a strong need for developing new cleaning methods especially for the Middle East and North Africa region, which do not consume water and have low capital and operational costs with less human intervention, especially for hot, arid, and dusty regions.

The continuous increase in the world's population and the fact that humans spend most of their day in indoor environments has increased the demand for energy. The rational consumption of electricity, especially lighting and its provision in buildings using various strategies, has become an important topic on the minds of many researchers and developers. In recent years, with the increasing the awareness of sustainable development due to economic and social conditions, daylight is seen as an effective way to save the energy, reduce significant pressures on existing energy infrastructure and reduce the environmental impact. The use of daylight in buildings by different sunlight applications/systems, whether traditional or innovative, is more than just an alternative or supplement to electric lighting, as it has many benefits in terms of economic, environmental, and health. Traditional applications are divided into three strategies: general, improving, and developing. The interior spaces of multi-story buildings (i.e., taller and deeper) are often not illuminated by natural light during the daytime, due to the distance from these spaces to the nearest traditional general application through which daylight must enter. Innovative Daylighting Systems (IDS) or remote source systems have been developed to transmit daylight into the building core (i.e., inaccessible places or rooms) and windowless areas or parts so they can be called Structure Core Daylighting Systems (SCDS). Eighteen SCDS/IDS were reviewed and discussed in the form of a comparison between them in terms of their components, historical progress, installation locations, and a brief description. The study focused on the systems that had already been commercialized or at least produced a large-scale prototype that had been installed in a real structure over the past five decades. Although SCDS/IDS are technically powerful enough to provide illumination for remote spaces, there are some important shortcomings that have hampered or prevented their widespread use, such as the extremely high-cost, efficiency for some of them, utilization difficulties, and application limitations. In addition, the equilibrium between the cost of their components and their performance efficiency is one of the great fundamental decisions that an engineer designing for these systems must make. Finally, the paper presents the latest design approaches that have been developed to overcome their identified shortcomings.

“…M.S. Mayhoub et al [83] proposed a method of cleaning, since IDS is mostly composed of mirror or glass materials, the accumulation of dust and dirt can also lead to a decrease in optical efficiency and glass transmittance. The recommended cleaning methods are air blowing, high pressure water flow, dragging brush cleaning, soft brush to rotate on the surface of the collector, spraying water, and wiping.…”

A Review of Daylighting System: For Prototype Systems Performance and Development

Daylighting systems make daylight illuminance possible, and the development of prototype daylighting systems can provide more efficient daylight illuminance. The purpose of this article is to review the development and performance of prototype daylighting systems in the last decade. The passive and active daylighting systems are listed separately and divided into the four categories by the presence and absence of hybrid. Each prototype daylighting system was evaluated in terms of cost and daylight performance and as well as their novel optical design. We evaluated the architecture and daylighting principles of each system by reviewing individual prototype daylighting systems. The cost of prototype systems still poses a challenge to development. How to use passive or active systems in different environments and whether or not electrical lighting assistance is needed is a controversial issue. However, active daylighting systems equipped with solar tracking systems are still mainstream. This research is a valuable resource for daylight researchers and newcomers. It is helpful to understand the advantages of various prototype daylighting systems and commercial daylighting systems that have been developed for many years; moreover, it is also possible to know the research directions suggested by the prototype daylighting systems. These will be of further use in developing innovative and better daylighting systems and designs.
