Lambda Wärmepumpen GmbH said its Eureka heat pump series uses a patented fluid mechanics system that reportedly improves heat transfer by four to six times while maintaining a temperature difference of just 3 K between the air and the refrigerant. Its seasonal coefficient of performance ranges from 4.50 to 6.10.

Croatian power company Hrvatska Elektroprivreda is seeking a developer to build a 56 MW solar power plant tied to up to 200 MWh of battery energy storage. The deadline to submit expressions of interest is May 12.

GCL Technology says its GCL Optoelectronic subsidiary plans a Hong Kong initial public offering (IPO) in 2026, alongside a potential 500 MW factory in the United States and a roadmap for space-based solar.

An international study has demonstrated that utility-scale solar PV paired with hydraulic hydro storage (HHS) could reach an LCOE as low as $0.022/kWh in select U.S. regions. The system could provide GWh-scale, cost-competitive, and highly reliable long-duration storage, capable of powering large commercial districts with minimal environmental impact.

Scientists in Australia claim that TOPCon cells are rapidly closing the open-circuit voltage gap with heterojunction counterparts, now under 10 mV, while offering greater wafer tolerance and high industrial scalability. Despite slightly lower efficiency, TOPCon-based perovskite/silicon tandems can achieve a levelized cost of energy comparable to heterojunction-based tandems due to reduced fabrication costs, according to the researchers.

Chinese power transformer manufacturer TBEA introduced a grid-forming string power conversion system (PCS) for utility-scale storage, renewable energy base projects, and weak-grid applications. The TE435/392K-HV-BL high-power converter focuses on improving power density and grid support. According to TBEA, its fully integrated liquid-cooling design increases volumetric power density by 78% and gravimetric power density by 32% […]

Company statements in a filing with the U.S. Securities and Exchange Commission indicate it will seek an arrangement between itself and creditors that may allow it to survive “as a going concern.”

In an interview with pv magazine, Carolina Novac, Secretary of State at Moldova’s Ministry of Energy explains how the country raised its solar capacity to 1 GW while advancing wind, storage, and regulatory reforms to strengthen energy security and reach 30% renewables by 2030. The Moldovan government is now focusing on scaling BESS, modernizing the power market, and enhancing cybersecurity through stronger policies and international cooperation.

Median solar module pricing in the United States reached $0.28 per watt as the market adjusted to intensified trade enforcement and new Foreign Entity of Concern compliance requirements, according to the Q1 2026 Quarterly Pricing & Domestic Content Report from Anza.

A UNSW-led team found that annealing conditions significantly affect stress, strain, and microstructure in copper-plated heterojunction solar cell contacts, with fast annealing increasing microstrain in both copper and indium tin oxide.
