March 24, 2026 Vincent Shaw GCL Optoelectronics, a unit of GCL Group, has secured a 1.2 MW commercial procurement project for perovskite tandem modules launched by Huaneng Clean Energy Research Institute, a key research arm of China’s Huaneng Group, according to a tender document published on Huaneng Group’s e-commerce platform on March 18. GCL Optoelectronics was named the sole winning…
Researchers in China have shown that integrating energy tower heat pumps with evaporator-side boilers, air source heat pumps or solar systems can significantly improve winter heating efficiency and economic performance in commercial buildings. Of the four configurations tested, the evaporator-side boiler and solar-assisted systems delivered the highest performance and energy savings, providing a sustainable, low-carbon alternative to conventional heating.

Researchers from the University of Ulm and the Friedrich-Schiller-Universität Jena have built a molecular system that captures solar energy in a water-soluble redox copolymer, stores it for several days with a charging efficiency of more than 80% and releases it when necessary as hydrogen with a conversion efficiency of 72%. March 24, 2026 Pilar Sanchez Molina Image: Elvira Eberhardt, University of Ulm By pv magazine España A research team from the University of Ulm and the Friedrich Schiller University Jena has developed a molecular solar battery that stores photovoltaic energy and releases it on demand as hydrogen – even in…
Job postings on Tesla’s website outline its 100 GW ambition and follow reports that the company is in talks with Chinese companies to purchase equipment worth $2.9 billion for solar energy production. March 24, 2026 Patrick Jowett Tesla is moving forward with its plan to deploy 100 GW of solar energy production on US soil by the end of 2028. The ambition is outlined in job vacancies available on Tesla’s website. A listing for a staff production development engineer in solar energy manufacturing based in Fremont, California, says the company wants to fill the role to “select and develop new…
The French energy regulator plans to link PV support to storage, as negative energy prices rise and solar revenues decline. March 24, 2026 Gwénaëlle Deboutte By ESS news The French Commission de Régulation de l’Énergie (CRE) is proposing changes to the rules for supporting large-scale photovoltaic installations, with the aim of encouraging the development of projects that combine solar energy generation with energy storage. The national energy regulator said the proposed adjustments, which apply to installations above 100 kWp, are part of a broader effort to improve the efficiency of public spending and better align the renewable energy sector with…
Tokyo’s power grid, like all other transmission system operators in Japan, has faced economic constraints as growth in solar power production outpaces the flexibility of the country’s largest regional electricity market. March 24, 2026 Brian Public Tepco power grid instructed sustainable producers to reduce production on March 1, 2026, from 11:00 AM (JST) to 4:00 PM, citing high solar power generation, low weekend demand and zero available inter-regional export capacity. It was the first time the utility had ever ordered economic containment. “The start of curtailment in the Tepco area is of great significance because it shows that even in…
By Brad Kramer March 24, 2026 By Martin Pochtaruk, CEO of Héliene | There are many reasons to be optimistic about the solar market and the future of domestic clean energy production in the United States right now. Solar continues to enjoy broad public and bipartisan support. More importantly, energy remains the cheapest form of energy, making it an economic choice even under rhetorical headwinds. And solar energy’s potential to meet rising energy demands and surpass older generation sources has been demonstrated time and time again, it’s a fact. Of course, there are still some sources of uncertainty and volatility…
The UK Government has today introduced new rules to implement the Future Homes Standard (FHS), which requires all new homes in Britain to be built with on-site renewable generation.The government expects that this will mainly be solar PV on roofs. The mandate to update England’s building regulations also includes improved insulation and heat pump installations.If confirmed last summerThe FHS will state that if developers cannot meet requirements to install rooftop solar PV coverage equal to 40% of a building’s floor area, a “reasonable amount” of coverage is still required. It was expected that the standard would come into effect in…
The US energy storage market reached a record 18.9 GW of battery energy storage system (BESS) installations in 2025, up 52% from 2024, according to the latest report.US energy storage monitor’ report released today by the American Clean Power Association (ACP) and sector analyst Wooden Mackenzie. A solar and storage project in Arizona, currently in the process of adding BESS. Credit: McCarthy Building Companies In the fourth quarter of 2025 alone, 5.8 GW was installed. Utility-scale installations accounted for 4.9 GW of that total, up 31% from the previous year. New operations were spread across 13 different states, showing market…
In an interview with pv magazineJay Johnson, the CTO of US cybersecurity company DERSec, explains that PV systems face cybersecurity risks that extend far beyond inverters, as evidenced by a December attack on Polish solar power plants, where wiper malware targeted substation equipment rather than the inverters themselves. Vulnerabilities often lie in backhaul communication channels such as APIs and mobile apps, making layered defenses, network segmentation and vigilant monitoring essential to protect distributed energy resources. March 24, 2026 Emiliano Bellini While solar inverters are widely believed to be the main target of cyber attacks, the threat landscape for solar PV…
