The Renewable Energy Test Center (RETC) raised the issue of ultraviolet-induced degradation of the trending technology in its PV Module Index 2022.

An international research team has presented all possible system designs and applications for photovoltaic-thermal (PVT) technology. Their review includes conventional PV-T collectors, air-based systems, liquid-based installations, water-based collectors, refrigerant-based systems, heat-pipe-based technologies, dual air-water systems, building-integrated PVT arrays, and concentrated PVT collectors.

Mauritian researchers have developed a solar tracker prototype that increases current by around 37%. The device uses a simplified and mechanical tracking system.

Data from the Australian Bureau of Statistics has shown that while renewable generation in Australia has increased significantly year on year, the country’s progress towards net zero is stymied by the failure to reduce consumption.

While many forecasting tools have been developed to improve forecasts of renewable generation, their accuracy is limited by the inherent predictability of the data used – that is, how predictable the renewable resource is in different regions and times of the year. University of Adelaide researcher Sahand Karimi explains why predictability matters and how considering it can save consumers and investors millions of dollars.

Australian researchers have developed a novel adaptive decentralised control strategy for electric vehicle (EV) integration, incorporating both microgrid and EV-side conditions into the primary frequency control. They have proposed new indices to evaluate the charge and discharge capabilities of EV batteries, as well as the satisfaction levels of EV owners.

Fraunhofer ISE scientists have optimised a technical concept for a hydrogen plant at sea. They claim that their design is “technically and economically viable.”

Dutch scientists have reported higher degradation risk for n-type TOPCon cells with EVA encapsulant due to potential moisture degradation. Front-side metallisation makes n-type cells more vulnerable than p-type cells, according to damp heat tests.

The debate continues over whether super-sized, high-power solar modules are a good thing for the industry and they appear to be here to stay. Vicente Parra and James Whittemore, from Enertis Applus+, consider the pitfalls to avoid when designing high-power solar projects.

The New South Wales government has tapped the ACE Energy consortium as the “first ranked proponent” to fill the network operator role for Australia’s first coordinated renewable energy zone that will host at least 3 GW of solar, wind and storage capacity.
