Technology and R&D

The Chinese manufacturer’s new battery energy storage system consists of an inverter ranging in size from 5 kW to 13 kW and a storage system of 10 kWh to 30 kWh. Up to five units can be connected in parallel.

It will be integrated with Fraunhofer ISE’s micro-CPV module technology, with 36.5% efficiency. A first prototype will be installed in Spain before the end of 2024.

Scientists in Finland have built a perovskite solar cell with a bio-inspired coating that reportedly improves light transmittance while providing self-cleaning properties. The film was able to improve the device efficiency by up to 6%.

In Germany – but not only there – there is a heated debate about the pros and cons of a capacity market. The German Renewable Energy Association is against it, and recently the German New Energy Industry Association, the DIHK and the EEX energy exchange have also taken a clear stance: Germany does not need a “power plant subsidy program.” In this article, four experts explain why battery storage can also play an important role in a capacity market and make recommendations on how the design of the market can help avoid mismanagement, wrong incentives and unnecessary costs.

The grid needs to modernize to meet a booming demand for electricity, which is only predicted to grow even further in coming years. IEC Standards are key to help with the transition.

French solar equipment supplier Monabee is expanding its range of solutions with two batteries – a physical and a virtual one, which can maximize the self-consumption of electricity produced by solar panels.

Chinese researchers claim to have developed an “ultrastable” perovskite solar cell based on a two-dimensional, Dion-Jacobson phase perovskite. The device was constructed with blade coating technology and is scalable, according to its creators.

The Chinese company said its new GT1 product is made out of hot-dip galvanized Q235B steel and can withstand wind speeds of up to 60m/s.

In its latest monthly column for pv magazine, IEA-PVPS provides a comprehensive overview of the state-of-the-art practices, best practices, and recommendations for managing reactive power amidst the growing integration of distributed energy resources (DERs). The article describes the regulatory frameworks and practical applications, underscoring the essential role of reactive power management in maintaining a stable and efficient power grid.

Scientists in Malta have created an after-market cooling solution that can be fitted to existing standard PV modules. The system is based on a water chamber placed at the backside of the module and can reportedly provide a net electrical energy gain of more than 9%.
