The Japanese manufacturer said its latest power semiconductor module is based on a compact insulated-gate bipolar transistor (IGBT) and is designed for large capacity industrial power converters voltage of 2,300 V.

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.

Greenfuel Energy’s new lithium batteries for residential applications are available in 12.8 V 100 Ah, 25.6 V 100 Ah, and 48 V 100 Ah configurations, with 1 kW to 5 kW of power.

While lithium ion battery prices are falling again, interest in sodium ion (Na-ion) energy storage has not waned. With a global ramp-up of cell manufacturing capacity under way, it remains unclear whether this promising technology can tip the scales on supply and demand.

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.

Pakistan’s National Electric Power Regulatory Authority (NEPRA) approved 221.05 MW of net-metering capacity in fiscal year 2022-23, with a total of 1,596 net-metering licenses issued nationwide.

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.

Researchers in Japan have discovered a stable, highly conductive material that can be used as electrolyte for solid-state lithium-ion batteries. The material’s ionic conductivity is said to be higher than any previously reported oxide solid electrolytes, with a wide operating temperature range.

India’s Shirdi Sai Electricals says it plans to install 10 GW of ingot-to-solar module production capacity and manufacture solar glass by March 31, 2026.

China’s National Energy Administration (NEA) and State Grid Corp. of China (SGCC) may ramp up PV curtailment to clear up space for new renewables projects that are struggling to obtain grid connections. Only up to 5% of PV output can currently be curtailed from solar plants, but the authorities are trying to decide whether to take a greater percentage of generation offline.
