PVEL reached 1 GW of damaged solar projects tested in the field

PV Evolution Labs (PVEL), US test lab for the global downstream solar industry, has now tested PV modules installed in more than 1 GW of solar projects that were damaged by force majeure events. The company reached this milestone by providing on-site electroluminescence (EL) imaging services for PV modules. EL images reveal latent damage in PV modules that undermines energy yield, safety and financial performance of solar assets over time.
»Field EL imaging techniques assist with quantifying damage at PV systems when they are struck by force majeure events such as wildfires, hurricanes and hailstorms,« said Gary Fleming, Senior Account Engineer of PERse, a managing general underwriter specializing in property and casualty insurance products for renewable energy power production facilities. »Field EL images can guide asset owners and O&M providers as they repair their plants and help ensure the accuracy of insurance claims.«
According to PVEL, the images are like X-rays: they depict internal cell cracks, heat stress and manufacturing defects in PV modules that cannot be seen by eye. Using a specialized near-infrared camera, PVEL technical staff take EL images in the field during the daytime while modules remain installed on mounting systems.
