Energy Vault completes 25 MW/100 MWh gravity-based storage tower in China
Energy Vault has started commissioning a 25 MW/100 MWh energy storage tower adjacent to a wind power facility near Shanghai.
Lightweight solar panel provides solution for rooftop installations
Australian installer UV Solar has rolled out a new frameless solar panel that manufacturer GoodWe says is 60% lighter than conventional PV modules, making it ideal for rooftops that are unable to support traditional PV and racking.
Redarc unveils 150 Ah lithium battery
The Alpha 150 battery, produced in the Netherlands by Australian electronics manufacturer Redarx, has a lifespan of more than 5,000 cycles and a continuous discharge rating of 200 A.
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.
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.
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.
Australian team claims 99% recovery rate with solar recycling process
Engineers at the University of New South Wales (UNSW) have developed a new, more effective method to recycle end-of-life solar panels. The technique allows them to quickly and efficiently separate 99% of PV cell component materials.
