=+24. By their nature, deserts are typically exposed to large amounts of solar radiation. Thus, such regions seem to be prime locations for harvesting solar energy through the installation of photovoltaic modules. These modules rely on an optical system to collect sunlight, often through some lens, so an important factor to consider would be the effect of desert sandstorms on lens performance. The authors of “Sandblasting Durability of Acrylic and Glass Fresnel Lenses for Concentrator Photovoltaic Modules” (Solar Energy, 2012: 3021–3025)
