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 …

Longi announces 27.09% efficiency for heterojunction back contact solar cell

Chinese solar module manufacturer Longi has achieved a power conversion efficiency of 27.09% for an HBC solar cell. Germany’s Institute for Solar Energy Research (ISFH) has confirmed the result. Longi said the result was enabled through a new laser graphical process that costs less than conventional high-cost photolithography processes. “This substitution has effectively reduced the cost of the BC …
