Rooftop solar demand outpacing EU member states readiness, says report

EU member states must play catch up to the growth and demand for rooftop solar or risk the area’s solar potential not being realised, according to a new report from the Climate Action Network (CAN) Europe. CAN Europe’s Rooftop Solar PV Comparison Update builds on its 2022 report into the EU’s rooftop solar market and …

Longi introduces HPBC photovoltaic modules with 22.8% efficiency

Chinese solar module manufacturer Longi has unveiled two new modules based on its proprietary hybrid passivated back contact (HPBC) cell technology. The company has yet to explain exactly what HPBC is, but it is believed to be an extension of p-type interdigitated back-contact (IBC) technology that combines the structural advantages of PERC, TOPCon, and IBC solar. Additionally, BC technology …

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 …

Make PV modules as cheap as possible, but not cheaper

The dream of solar cell and PV module manufacturing outside of Asia has become increasingly distant. A combination of falling PV module prices and China’s PV module manufacturers allegedly sitting on up to two months’ worth of stock is adding to the maelstrom. Plans for GW-scale PV cell and module production facilities in the US and Europe …
