Researchers in Canada have created an experimental workbench for aboveground compressed air energy storage. Experimental data calibration reportedly ensured model accuracy with a mean absolute percentage error below 4.0%.

The Spanish company said that its new tracker “is designed for maximum adaptability to any terrain.” It works with all PV modules.

Although local defects in chloride-iodide-based perovskite are hard to avoid due to ion migration, a group of scientists have now found a way to passivate them. They used different combinations of 4-chlorobenzylammonium chloride and 4-chlorobenzylammonium bromide on top of the hole transport layer and reached up to 15% improvement in efficiency.

US-based Bluetti has developed a new energy storage system (ESS) that offers up to 154.8 kWh of storage and 60 kW of output by connecting up to three systems in parallel. It includes an inverter and a voltage controller with up to seven batteries.

Researchers have developed a novel deep-learning method to predict ultra-short-term PV power, using an optimization method that is based on the behavior of dung beetles. The proposed approach reportedly performed better than seven other conventional prediction methods over a 1-year period.

The Chinese company said that, under a new agreement, it will collaborate with Xinjiang Silk Road to produce high-efficiency HJT PV modules. It will supply silicon wafers, cells, modules, and more.

A research group has proposed a novel method to control ramp rates in power networks. Its control optimization is based on weather, load and production forecast data. The scientists simulated the operation of the proposed technique and reached a ramp rate reduction of up to 76.2%.

Metrel, a Slovenian measurement equipment supplier, says its new electrical installation safety tester can assess systems with a maximum voltage of up to 1,500 V and a maximum short circuit current of 40 A.

The Swiss manufacturer said the cell was developed in partnership with Echion Technologies, which supplied the niobium-based active anode material. It has greater energy density and faster charging compared to LTO technologies.

An international team of scientists have combined cyclic-olefin copolymers with a powder of aluminum oxide to create a filament that can be used by a 3D printer to create anti-reflective covers for PV modules. The proposed innovation can reportedly improve PV cell efficiency by over 25%.
