Suniva has agreed to supply domestically manufactured solar cells to Heliene under a three-year sourcing contract, for integration into its solar modules.

The International Renewable Energy Agency (IRENA) says developers installed 345.5 GW of solar throughout the world in 2023. China mainly drove the surge, accounting for nearly three-quarters of all new renewable energy, but IRENA says more equitable growth will be needed to hit 2030 deployment targets.

The monthly charge would be assessed regardless of any energy conservation efforts or solar production at home. Eighteen California Congressional representatives wrote a letter to the Public Utilities Commission warning the proposed charge would harm low- and middle income residents and “undercut investments in renewable energy.”

US-based Thornova said its new panel features a power conversion efficiency spanning from 22.4% to 23.2% and a temperature coefficient of -0.29% per C. The company is a subsidiary of China-based manufacturer Sunova Solar and is currently planning a cell and module factory at an unspecified location in the United States.

Retail giant Walmart has signed a number of new agreements with solar developers across the United States, furthering its position as a corporate leader in PV adoption.

Enapter has secured four new orders for its AEM Nexus 1000 megawatt-class electrolyzer, while Fraunhofer IWU says it has started working on electron beam welding technology to overcome the speed limitations of laser beam scanner welding.

The US Department of Energy (DoE) has announced up to $22 million in funds under its Renewable Energy Siting through Technical Engagement and Planning (R-STEP) program.

Researchers in the U.S. have repurposed a commonplace chemical used in water treatment facilities to develop an all-liquid, iron-based redox flow battery for large-scale energy storage. Their lab-scale battery exhibited strong cycling stability over one thousand consecutive charging cycles, while maintaining 98.7% of its original capacity.

Maxeon said it has achieved a 24.9% efficiency rating for a full-scale Maxeon 7 solar panel using its IBC technology. The US National Renewable Energy Laboratory (NREL) confirmed the result.

There may be a global solar boom but a drastic revision of California’s net metering program has ruptured the industry overnight and is affecting everyone from installers to financiers to makers of power electronics.
