Control tech for modular gravity storage

A group of researchers in China has developed an energy management system for modular gravity storage. Compared to single block gravity storage, the modular counterpart offers more flexibility in output power, ease of mass production of related equipment and better flexibility in the selection of weights.

Longi announces 27.09% efficiency for heterojunction back contact solar cell

Longi has announced the achievement of 27.09% efficiency for its heterojunction back contact solar cell, a result that has been confirmed by Germany’s Institute for Solar Energy Research.

Researchers claim record-breaking 14.46% efficiency for organic PV module

A team of scientists at Germany’s Friedrich-Alexander Universität Erlangen Nürnberg has set an efficiency record of 14.46% for an organic PV module. The performance was certified by Germany’s Fraunhofer Institue for Solar Energy’s PV calibration laboratory.

Master-slave technique for deploying parallel inverters in PV systems

Scientists in Czechia have proposed to use parallel inverters in PV systems to not only reduce instability, but also to increase power yield. The proposed approach reportedly results in higher maximum power point tracking (MPPT) performance.

PEP invests $250 million in electric vehicle charging

Electric vehicle charging in Australia and New Zealand has been given a boost with fund manager Pacific Equity Partners acquiring a majority stake in Australian electric vehicle charging solutions provider EVSE to the tune of $250 million (USD 167 million). The partnership also involves PEP-backed smart metering specialist Intellihub.

Solar bike paths go online in Netherlands

Two new PV bike-path projects are now operating in the Netherlands under an initiative launched in 2018 by Rijkswaterstaat, the Dutch water management agency.

AVL progresses ‘pit to battery’ strategy with vanadium electrolyte manufacturing facility

Construction of Perth-based minerals company Australian Vanadium Limited’s first commercial vanadium battery electrolyte manufacturing plant has been successfully completed as part of the company’s broader value-adding vision.

Waste heat from PV panels used to generate residential hot water

Scientists in the United States has developed a new photovoltaic-thermal system design that utilises parallel water pipes as a cooling system to reduce the operating temperature of photovoltaic panels. The waste heat generated by this process is then used to generate domestic hot water.
