Long Term Testing over 6 Years on Crystalline Silicon Solar Modules with Snail Trails

Review of technology specific degradation in crystalline silicon, cadmium telluride, copper indium gallium selenide, dye sensitised, organic and perovskite solar cells in photovoltaic modules: Understanding how reliability improvements in mature technologies can enhance emerging technologies

“…These are performance risks. Consequently, some reports indicate that the impact of snail trails on PV performance is negligible, 36 but other studies conclude that output energy produced by PV modules can be reduced up to 20% due to snail trails. 37,38 It appears that in the latter case, positive correlations between the occurrence of snail trails and power loss were misinterpreted as causal, whereas instead they have a common origin (moisture ingress, leading to more problems than snail trails alone).…”
