Water-spray cooling system improves PV module efficiency by 28% in arid setting
Researchers have developed a smart water-spray cooling system for PV panels that activates only when temperatures exceed a set threshold, boosting efficiency while minimising water use in arid conditions. The system raised power output and reduced module temperatures, offering similar efficiency to continuous cooling but with far lower water consumption, pump operation, and costs.
New method to predict solar module lifespans under sand erosion
A team of researchers in Algeria has designed a new testbed and a novel acceleration law that accounts for both wind speed and sand density. The new methodology was tested on four PV modules and showed lifespans of up to 47 years in terms of sand impact.
China hits 277.17 GW of new PV installations in 2024
China’s cumulative installed solar capacity hit 886.66 GW at the end of 2024, with 277.17 GW of new annual installations, up 45.48% year on year. The deployment surge exceeded forecasts, setting a new historical record for PV installations.
GoodWe unveils hybrid inverters for homes with weak wireless service
