New algorithm to detect shadows in rooftop PV systems
Dutch scientists have developed a new algorithm to isolate shadow-related PV system malfunctions and estimate potential energy losses caused by shadowing.
Video: Singapore Solar Exchange CEO discusses polysilicon prices in 2023
Sakura Yamasaki, the founder and CEO of Singapore Solar Exchange, speaks to pv magazine about China’s recent decision to launch the trading of industrial silicon futures, following a year of high polysilicon prices. Yamasaki discusses the potential impact on polysilicon prices in China, the outlook for domestic price stabilization and risk mitigation, and what this might mean for the global solar industry in 2023.
Hanersun releases 695 W TOPCon solar module with 22.37% efficiency rating
China’s Hanersun has unveiled its HItouch 6N module series, which is based on n-type TOPCon tech, 210 mm wafers, and half-cut cells. The monofacial and bifacial modules feature power outputs ranging from 605 W to 695 W and efficiency ratings of 21.38% to 22.37%.
Techniques to build thermally co-evaporated mini perovskite solar panels
Scientists in Singapore have reviewed all thermal evaporation techniques for the production of perovskite solar cells and modules. Despite limitations, the new methods could lead to high production throughputs and more efficient products.
US startup to build 100 MW solar plant with modules on ground
Erthos claims that with its new installation method, solar facilities could occupy just one-third of the surface covered by conventional PV plants, potentially reducing installations costs by up to 20%.
