Monocrystalline solar modules more resistant to hail than polycrystalline panels

An international research team has developed a new experimental setup to conduct hail impact tests for solar modules. The setup consists of an air compressor, pressure chamber, launcher barrel, and ice ball speed measuring apparatus. The latter is based on an adjustable barrel, and solenoid valve ensuring precise testing in controlled conditions. The scientists explained …
