Manufacturing

Indian solar company Saatvik Solar’s new facility in Haryana is equipped to make mono PERC, half-cut, multi-busbar technology, to produce high-efficiency PV modules with 530-610Wp of power output.

In 2002, the Fraunhofer ISE patented the HERIC circuit for highly efficient inverters. Since then, the institute says, it has recorded out-of-court settlements in seven patent infringement lawsuits against companies from China, Taiwan and Germany.

Perovskite-silicon tandem cells offer one of the surest pathways to much higher solar efficiencies, one that has moved close to commercialisation in the past few years. Much of the work getting to this stage has naturally focused on developing a viable perovskite top cell. Optimisations to the silicon layer underneath, however, will also be important to the overall device function and efficiency. Scientists in Germany examined five different silicon cell concepts similar to those in mass production today, finding that with a few optimisations these could reach efficiencies up to 30.4%.

Developed by French start-up Ecosun, the trailer is equipped with 15 solar panels with output of 360 W and batteries with a storage capacity of 23 kWh. It can be used for construction sites, military camps and water pumping systems.

Researchers in Portugal have tested how vanadium redox flow batteries can be integrated with rooftop PV to balance the system load to ensure firm power output. They proposed a 5 kW/60 kWh battery configuration for a 6.7 kW building-integrated PV microgrid. According to their findings, the battery can be used in different energy management strategy scenarios to better complement solar photovoltaic generation.

U.S.-based hydrogen vehicle maker Hyzon has announced Melbourne will soon be home to its Australian headquarters as part of a newly formed partnership with RACV, which will see the pair develop a purpose-built facility for Hyzon out of RACV’s Noble Park operation in the city’s south east.

Designed by Chinese provider Mibet, the mounting structure can be used for different crop types. The system offers a tilt angle of up to 30 degrees and can host either framed or frameless solar modules.

On the company’s Q4 earnings call, the world-leading EV manufacturer again prioritised delivering cars over growing low-margin energy storage products, while solar products were barely noted. Both verticals grew though, solar by 68% and storage by 32%.

Australian financial institution Bendigo and Adelaide Bank has turned to solar PV to improve its bottom line with a 200 kW rooftop system installed atop its major corporate site in Bendigo in regional Victoria.

An international research team has investigated how solar could be combined with thermoelectric coolers (TECs), which are small solid-state heat pumps used either for heating or for cooling. A system was built with six solar panels, an air duct system, four batteries, a charge controller, TECs, an inverter, heat sinks, a test chamber, and condenser fans.
