Using shunts to spot PV module degradation

Scientists in Ireland investigated the effect of shunt resistance on a PV cell’s electrical performance. The group says its finding could potentially lead to the development of models for early detection of various forms of cell degradation, allowing for intervention to repair or replace components before major power losses occur.

GreenH building 1 GW electrolyzer fab in India

The company’s manufacturing plant in Haryana will produce proton exchange membrane (PEM) electrolyzers based on the technology from its Spanish parent firm H2B2 Electrolysis. The plant will start production by October.

TOPCon PV modules outperform PERC by more than 5% in energy yield tests

A study by TÜV Nord in Malaysia shows that the latest generation of tunnel oxide passivated contact (TOPCon) modules surpass their older rivals on energy yield. The researchers compared n-type TOPCon modules with older p-type PERC modules, both manufactured by JinkoSolar over a three-month period earlier this year. The newer product showed an energy yield 5.69% higher than its PERC counterpart.

UK coal-fired power plant site to host 1,040 MW/ 2,080 MWh battery

Independent energy infrastructure developer Carlton Power has secured planning consent for a 1,040 MW/ 2,080 MWh battery energy storage system (BESS). The project is expected to strengthen the resilience of the energy system in northwestern England.

German research institute unveils 99.74% efficient power electronics for solid-fuel heat pumps

Germany’s Fraunhofer Institute for Applied Solid State Physics (IAF) has developed an ultra-efficient circuit topology for voltage converters with an electrical efficiency of 99.74%. The tech could considerably raise the coefficient of performance for electrocaloric heat pumps and the scientists are now considering components based on semiconductor gallium nitride (GaN) for higher power density and efficiency.

Autonomous robots gaining traction with solar installers

Sarcos Robotics and Terabase Energy recently announced key business developments, underscoring how installation robots are increasingly moving from test centers to the field.

Revkor, H2 Gemini unveil plan to build 20 GW HJT perovskite cell, module factory in U.S.

The two companies are targeting to reach an annual production capacity of 20 GW by the end of 2025. Manufacturing activities are scheduled to begin in the second quarter of next year.

Energy communities operating on hydrogen, batteries

Researchers in Spain have studied the impact of hydrogen production and storage technologies in risk management for energy communities with internal price-tariff systems. They found that the optimal involvement in futures markets and spot markets will depend on a community’s risk aversion and self-sufficiency.

ReNew signs MoUs worth $7.8 billion for green energy projects

Power Finance Corp. (PFC) and Rural Electrification Corp. (REC) committed debt funding of $3.9 billion each.
