Mining major Anglo American has struck a deal with Stanwell to power its Australian operations with 100% renewable energy from 2025 onward as part of a 10-year power supply deal.

The Industrial Technology Research Institute (ITRI) and United Renewable Energy (URE) have developed a solar panel that can be easily dismantled to simplify the recycling process. They claim that 96% of the materials in the panel can be recovered, including all of the solar cells and front glass.

The SisAl Pilot project produces solar-grade silicon from Spanish quartz without using coal and with zero CO2 emissions. The company behind the project claims that the process is cheaper and more sustainable.

With installers who cater to African businesses making the headlines this year, Jasper Graf von Hardenberg – whose C&I solar business was recently bought by Shell – explains here how the story of the continent’s commercial and industrial (C&I) solar segment was far from an overnight success.

PG&E has secured approval to set up a vehicle-to-grid (V2G) export compensation mechanism for commercial EV charging customers in California. Sono Motors is debuting its Sion solar electric vehicles in the US market, while Toyota and Jera are installing innovative second-life battery systems in Japan.

The US National Renewable Energy Laboratory (NREL) says in a new report that PV module lifetime extensions should be prioritized over closed-loop recycling to reduce demand for new materials.

A new study of the environmental impacts of renewable energy finds significant opportunities for solar to reduce its impacts in various categories, including human health, resource depletion, and environmental damage. The study notes in particular that more work is needed to establish a comprehensive reuse and recycling network for end-of-life PV products.

A team of researchers from the University of New South Wales (UNSW) has proposed a novel cost-effective way to recycle silicon solar panels. Their process consists of module deframing, laminate shredding and material concentration using electrostatic separation, reducing their original weight by 2% to 3%.

With the last incumbent to enter and leave the revolving door of UK prime ministers having caused alarm by reportedly preparing plans to effectively ban big solar on farmland, Harald Överholm, CEO of clean energy company Alight, says politicians need to put discredited arguments behind them and get on with the urgent business of shoring up energy security.

German company Mefa Befestigungs- und Montagetechnik has developed absorbers made of polypropylene that are intended to simplify the use of brine heat pumps. The novel technology should make it possible to combine multiple heat sources, including water, earth, air and also ice storage all within a single system.
