Optimization technique to extract unknown PV system parameters from manufacturers’ datasheets
Developed by an international research team, the proposed methodology can reportedly be used with all kinds of solar panels and under different environment conditions. It relies uniquely on the specifications of the modules’ datasheet, temperature and insolation intensity.
The impact of nonuniform soiling on PV system performance
A UK-Saudi research group has investigated the impact of uneven soiling on PV modules and has found that it can lead to enhanced performance losses due to different operational effects at intra-cell level. The academics conducted a series of experiments on a residential rooftop in Muscat, Oman, throughout 2021.
Vehicle-integrated photovoltaic system for medical support
A spinoff of Germany’s Fraunhofer Gesellschaft has developed a compact vehicle-integrated PV system integrated with medical support equipment to provide off-grid, off-road mobile healthcare in rural communities. The PV modules with integrated energy management system supply all the electricity required for maintaining a cold chain for vaccines, medicines and samples.
Chinese PV Industry Brief: Datang to procure 16 GW of solar modules
Datang has kicked off the procurement process for 16 GW of solar modules, including 13 GW of tunnel oxide passivated contact (TOPCon) panels, 2 GW of passivated emitter and rear cell (PERC) modules, and 1 GW of heterojunction products.
Perovskite-perovskite tandem solar cell based on tin-lead top device achieves 28.20% efficiency
Developed by a research group in China, the two-terminal all-perovskite tandem device utilizes a 23.11%-efficient single-junction top cell relying on an optimized Sn-Pb perovskite material. The perovskite-perovskite cell was also able to retain 95.7% of the initial efficiency after being stored in a glovebox for 2,200 h.
Shirdi Sai Electricals targets 10 GW of ingot-to-solar module capacity
