Customer ServiceThe greatest contributor to insured losses on solar PV systems worldwide is severe hail. Severe hail events are forecasted to increase in frequency over time, emphasizing the increasing importance of designing and preparing for solar PV resilience to hail. Many areas are prone to hail events, and the level of risk a site faces may not be intuitive.
In particular, hail damage seriously affects photovoltaic systems. The severity of hailstorms as well as impact responses are important factors in mitigating loss, so the first research area that needs to be addressed is the resistance of photovoltaic modules to hail.
In the event of a hailstorm, photovoltaic modules in their hail stow position (inclined with their normal vector as perpendicular as possible to the hail direction), have a lower exposed surface area than modules not moved to a specific stow position. Consequently, the former receive less hailstone impacts than the latter.
The visual and electroluminescence images of damage to the solar panels after hail impact are shown in Fig. 9 (a, b). In the visual images, we can only observe the cracks generated on the glass of photovoltaic panels. This dispersion indicates the scattering of glass in various directions resulting from the impact.
It can lead to severe damage, as shown in Fig. 1, due to a hailstorm in 2014 in Brisbane (Australia) with a nominal hail size of 25 mm. Some studies have been done to investigate the effect of hail loads on the performance of PV modules by simulating hails using pressurized mechanisms.
Quantification of the effect of hail load on electrical properties of the solar module was done through a solar flash testing apparatus, developed at UET Peshawar as per IEC 60904-1 standard [ 33 ]. In this test, the module was exposed to sunlight (Solar Irradiance Level 800–815 W/m 2) at cell temperature of 25 °C.
