Rooftop PV

The Japanese conglomerate has deployed its Panasonic HX hydrogen solution at its facility in Munich. The system uses an AI-based energy management system that reportedly makes battery storage unnecessary.

Australian solar distributor OSW Group has enhanced its free solar, battery design and installation business tool, GreenSketch version 3.0 with new AI-powered features, that simplify and accelerate workflows.

Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE) has developed a new way to quantify PV self-consumption in Germany using national register and grid-operator data, amid a steady rise in onsite use as installations and storage capacity expand.

Following reports of fraudulent solar inspections, Poland’s energy regulator has issued an announcement clarifying who is authorized to conduct such assessments. 

The Japanese electronics manufacturer is testing its glass-based perovskite solar PV technology in office windows made by YKK AP, a construction and building materials company.

Chinese manufacturer Sunman is to build a 500 MW per annum solar module production facility in the New South Wales Hunter Valley after securing funding support from both the state and federal governments.

Australian researchers developed a high-resolution energy modeling framework to assess how PV and batteries can supply 24/7 electricity to heavy industries, considering cost, grid interaction, and load flexibility. They found that, while technology cost reductions help, smart grid integration and flexible industrial operations are far more effective in lowering electricity costs and enabling 100% renewable energy use.

Dongkuk CM has introduced an ultra-high-reflectivity color steel sheet designed to boost the performance of bifacial rooftop PV systems, increasing solar reflectance to 80–85. The new material also offers enhanced corrosion resistance, long-term durability, and added cooling benefits thanks to its advanced plating and dual-layer design, according to the manufacturer.

A coalition of 18 California legislators has formally urged the California Public Utilities Commission (CPUC) to enforce regulations under “Rule 21” regarding the interconnection of customer-sited solar and energy storage systems.

Latest boiler upgrade scheme (BUS) data reveals more than 100,000 applications for heat pump grants have been made since support scheme launched in May 2022. Demand has significantly increased in 2025, and the scheme was expanded in early November to include an air-to-air heat pump grant.
