A machine learning model uses cloud type and cloud cover to predict rapid changes in surface solar irradiance, including short-term “ramp” events that affect grid stability. When tested across 15 global sites, it showed strong generalizability, with most locations matching or exceeding the original model’s predictive performance, though extreme climates performed less consistently.

Eight US solar manufacturers have filed an anti-circumvention complaint with the US Department of Commerce, alleging that solar cells and modules assembled in Ethiopia using Chinese-origin components are evading existing antidumping and countervailing duty orders on Chinese solar products.

A Cornell University research team developed a control framework that simultaneously considers past and future conditions when determining solar panel tilt angle. The researchers told pv magazine it is designed to be plug-and-play, allowing for software developers and solar operators to incorporate their optimization algorithms directly into the framework.

Amazon has conducted a six-month field trial of a rooftop heat pump system developed by U.S. startup Transaera at one of its logistics facilities. The system uses metal–organic framework (MOF)–based dehumidification to remove moisture from outdoor air before cooling.

U.S. researchers have developed an IR-CW laser-based method to remove backsheets from end-of-life silicon solar modules without damaging the glass or wafers, using controlled heating of the silicon–EVA interface through the front glass. The process enables clean mechanical delamination with preserved device performance and offers a lower-energy, lower-cost alternative to conventional thermal or chemical recycling methods.

Strategic agreement will see California-based renewables developer ramp up sodium-ion battery deployment. Deal follows Alsym Energy entering 8.5 GWh partnership with iron flow battery business ESS.

The OFW Solar Project in Virginia submitted an application to connect to powerlines run by the wrong power company, instead of a second set of nearby transmission lines, necessitating a total restart of the PJM interconnection process that could push construction back to 2032.

The automotive giant has formally unveiled Ford Energy, its new battery energy storage subsidiary, alongside initial details of its flagship grid-scale energy storage product.

Insurers tell pv magazine that severe convective storms (SCS) drove $60 billion in insured losses in 2025, a mounting toll that has become the primary force tightening capacity and raising prices across the solar energy insurance market.

Severe shortages of power transformers are stalling grid expansion as developers face skyrocketing prices and four year wait times for critical equipment.
