AI tech for DC arc detection in PV systems
Scientists from China have developed a novel system that can detect DC arcs in PV installations through a back-propagation neural network. The novel technique reportedly ensures a detection time of less than 200 ms.
SAJ launches new microinverters with 4 MPPT channels
SAJ’s new M2 microinverters support PV panels ranging in size from 400 W to 700 W. They have a maximum output of 2,250 VA, with four maximum power point tracking (MPPT) channels. The company claims a peak efficiency of 97%.
Chinese authorities complete 50 MW of PV at altitude of 5,000 meters
The Chinese government says the 50 MW Caipeng PV plant has been completed with 40 MWh of battery storage at an altitude of 5,000 meters in Tibet. The project is connected to a new 35 kV transmission line.
The effect of PV plants on albedo, vegetation, land temperature
Scientists have used remote sensing to analyze the effect solar farms have across 116 sites worldwide. They found that the cooling effect is higher during the daytime, with albedo decreasing by 0.016 for most facilities.
Futurasun starts construction of 2 GW back contact module factory in China
The Italy-based solar module manufacturer said it is progressing with its previously announced transition from module manufacturer to a vertically integrated manufacturer with 12 GW of cell capacity. It also said the project to build a module factory in Italy is going through a “complicated process.”
