Researchers in Portugal found that Iberian heatwaves can cause sharp but short-lived PV yield losses, mainly during peak temperature hours due to module heating and inverter derating.

China's battery cell manufacturing capacity could exceed projected global demand by 2030, according to a new Carnegie Endowment report, which recommends selective cooperation with Chinese companies to reduce supply chain risks.

S&P Global Energy’s 2026 Tier 1 Cleantech Companies list recognises leading suppliers across solar, inverters, wind, battery energy storage systems, and introduces a new battery cell category, using expanded criteria that include market leadership, sustainability, and financial resilience. The update comes as cleantech markets diverge, with solar facing oversupply and margin pressure while battery storage demand accelerates, prompting manufacturers to diversify and adapt to evolving market and regulatory conditions.

Daikin has unveiled an inverter-driven rooftop heat pump offering 7.5-ton to 10-ton capacities and cooling efficiencies of up to 22 IEER. The system uses difluoromethane refrigerant and reportedly achieves a coefficient of performance of up to 3.85 at 8.3 C

Enercity is building a 50 MW power-to-heat plant in Hanover to support its coal phase-out, decarbonize district heating, and absorb surplus renewable electricity. The facility will expand the utility's flexibility by converting excess power into heat for the district heating network and storage systems.

Reden has halted solar module production at its Roquefort-sur-Soulzon facility, citing mounting cost pressures and competition from Asian manufacturers. The closure marks another setback for French solar manufacturing, leaving Voltec as the country's only remaining PV panel producer.

An international research team developed a triple-junction all-perovskite solar cell using a graphene oxide (GO)/self-assembled monolayer (SAM) bilayer contact strategy to overcome SAM-related charge extraction losses and improve interface quality.

The Chaos Computer Club has identified a security vulnerability affecting photovoltaic installations that use Hoymiles inverters.

Avaada Electro Ltd, the solar PV manufacturing arm of Avaada Group, has operationalized the first 3 GW phase of its 6 GW high-efficiency n-type TOPCon solar cell manufacturing facility in Butibori, Nagpur.

Brazilian solar installer Alba Energia is using smart power controllers combined with Aneel's simultaneity rules to overcome reverse power flow restrictions and enable larger distributed solar arrays. The approach allows PV system owners to maximize on-site solar generation while keeping grid exports within utility-approved limits.
