Solar power generates proven, predictable and economical energy and new innovations have made solar PV power plants easy to deploy, integrate and maintain. Areas with large solar energy potential are among the dustiest in the world. At first glance, solar would be a natural fit in many of these environments but humidity, airborne dust, and wind of these regions often bring high soiling rates that can accumulate to reduce performance by up to 10% per month on average, where soiling can be a major loss factor that affects the energy yield for PV plants especially in humid and dusty climates. Therefore, to achieve the desired performance ratio and obtain stable generation, mitigation solutions are proposed to overcome dust issues that affect the performance of PV plants. This makes PV module cleaning a key component for long-term plant performance and sustainable profitability. In this paper, a review of the mechanisms and mitigation solutions to overcome soiling on solar installations using real-world testing and verification is investigated with emphasis on dry type cleaning methods. © 2014 IEEE.
