New documents reveal U.S. government found two cases of communications in Chinese inverters that differed from official documentation. The discrepancies were deemed “non-malicious” and “non-intentional” by investigators.

UL Solutions has released design standards for balcony solar, also known as plug-in pv, along with whitepaper highlighting three main risk categories of balcony solar in the US consumer market.

Ohm analysts tracked over 150 actions taken by utilities, regulators and legislators in 2025 and noted a 153% year-over-year increase in residential battery enrollments, with ample room to grow.

The collaboration will integrate Leap’s distributed energy platform with EG4’s hardware ecosystem, which the companies say will allow homeowners to monetize their energy storage systems through automated grid services while maintaining backup reliability.

U.S. scientists used density functional theory to reveal how sodium ions are stored in nanoporous carbon anodes for sodium-ion batteries, identifying dual ionic and metallic storage mechanisms within the pores. Their findings provide practical design guidelines to improve battery voltage, safety, and commercial viability for stationary energy storage.

An international research team has developed a new two-dimensional perovskite interlayer based on a co-crystal engineering strategy for more robust perovskite films. It demonstrated improved performance in small area perovskite solar cells and, in a 48 cm2 module, contributed to retain 95% of initial efficiency after 5,000 h.

Company also seeks terrestrial applications for its lightweight, flexible modules.

Power control and energy management systems (PCS and EMS) are powerful tools that will enable the next generation of electrical systems, and the way they are featured in the 2026 NEC is a testament to the ways they can unlock the capability of distributed energy systems and more fully utilize the capacity of electrical infrastructure.

The Kauaʻi Island Utility Cooperative in Hawaii, which deployed storage before grid-forming inverters became available, became a test case for diagnosing grid issues that can arise with older grid-following inverters, and how grid-forming inverters can stabilize a grid.

A new Perspectives research study on the future of the global PV supply chain outlines how module prices, performance, and lifetimes could evolve over the next 25 years. The work reflects a collaboration among leading solar research institutions worldwide. One of the study’s authors, the director of the Fraunhofer Institute for Solar Energy Systems (ISE), told pv magazine that solar module and cell efficiencies could exceed 35% by 2050, with panel prices expected to drop by a factor of two.
