IEC Issues New Standard for Testing Resistance of Solar Modules to Heavy Snow

The International Electrotechnical Commission (IEC) has issued a new standard – the IEC 62938:2020 – to test the resistance of solar photovoltaic modules to large amounts of snow piling up on their surfaces. The IEC defines the test standard as a method for determining how well a framed PV module performs mechanically under the influence of inclined non-uniform snow loads.

IEC Adopts Standards for Standalone Solar Energy Kits

… In January, IEC Technical Committee 82 voted unanimously to approve publication of Technical Specification 62257-9-8, which contains quality standards for pico-solar products and solar home system kits with PV modules rated up to 350 watts. These standards are an updated version of the Lighting Global Quality Standards, developed by the World Bank Group and used widely around the world. Together with the corresponding test methods (IEC/TS 62257-9-5), these quality standards form the foundation for quality in the off-grid solar sector.

Staying afloat, whatever the weather

… “It’s an environment that can be highly corrosive, there is a lot of vibration with the waves, and the whole thing is moving with waves and the wind,” says Sinapis. “The type of conditions we see in our test array go well beyond the current IEC standards. We think there should be reevaluation of these standards, and some parts added for floating PV systems specifically.”

… “We have observed that the cables in a few sections in our test bed lead to lower insulation resistances, which in turn cause the inverters to temporarily not connect the array for safety reasons, i.e. due to suspected leakage currents,” says Thomas Reindl. “This may be due to the high moisture content around the insulation of the cable. We are also involved in the IEC standards committee for PV systems (TC 82 WG 3) to utilize the findings from our test bed to develop system-level standards for FPV, to the benefit of the whole PV community.”
