  "description": "<p>Photovoltaic modules can experience damages of varying severity in the case of heavy hail storms. In the&nbsp;worst case, complete&nbsp; glass and solar cell breakage results in efficiency and security losses of the affected&nbsp;modules which therefore have to be replaced. However, there is a strong need to inspect the remaining&nbsp;modules directly in the field in order to assure no hidden damage. Three&nbsp; hail-affected photovoltaic plants&nbsp;in the south of Austria were investigated first with common standard methods like analysis of the&nbsp; plant&nbsp;monitoring data and thermography. Then, these plants were additionally investigated by novel nondestructive&nbsp;methods. With&nbsp; the aid of two innovative characterisation tools, outdoor electroluminescence&nbsp;and UV-fluorescence imaging, hail-induced damaging&nbsp; of solar cells can be detected even when the&nbsp;solar glass of the modules withstood the mechanical impact of the hailstorm and no&nbsp; damages are visible&nbsp;to the naked eye or well recognizable by thermography. The non-destructive, easy to handle and fast&nbsp;characterization technique UV-fluorescence imaging allows the detection and visualisation of hail&nbsp;induced cell damage.&nbsp; Modules&nbsp;showing partial cell breakage and/or micro cracks e as proven by outdoor&nbsp;electroluminescence measurements e and lead&nbsp; to a reduced electrical performance can be unequivocally&nbsp;identified.&nbsp;</p>",
