While Brazil wastes billions of real on curtailment, the electricity sector is demanding urgent action on an energy storage capacity reserve auction which is now not expected until 2026. ‘What is missing is the courage to unlock the market,’ said Greener CEO Marcio Takata.

Researchers have simulated 160 cases of PV rooftop installation in southern and northern Italy. Among changing parameters were size and type of the panels, as well as their roof cover rate. The considered albedos were 20%, 40%, 60%, and 80%, representing different types of roof materials.

Researchers in India say that photovoltaic-thermal (PVT) systems offer greater performance stability than conventional PV systems in hot climates. Using irradiance and temperature data, the team applied a Random Forest model that predicted efficiency classes with 97% accuracy.

JinkoSolar expects the PV market transition to last until 2027-28 due to negative power prices and project delays in Europe. In an exclusive interview with pv magazine, Vice President Europe Frank Niendorf says growth will recover as storage and hybrid systems expand and consolidation progresses.

Cornex Chairman Dai Deming discusses battery prices and R&D prospects in an exclusive interview with pv magazine. He says the company’s effective production capacity exceeded 110 GWh in the first quarter of 2025, ranking second in the lithium-ion battery industry.

China Energy Engineering Corporation’s landmark procurement signals a shift toward market-driven energy storage, with bids reflecting aggressive cost-cutting and rising industry consolidation.

Researchers have demonstrated that the theoretical optimal tilt for rooftop solar energy production in low-cost buildings in Nigeria is approximately 5.67°. Their modeling suggests to adopt south-facing roofs for PV generation in the Global South.

The Spanish government has approved legislation to strengthen its electricity system following the major power outage the country experienced in April.

WHES has launched a new series of commercial and industrial (C&I) storage systems with integrated hybrid inverters, offering capacities from 57 kWh to 100 kWh and PV input up to 96 kW. The China-based manufacturer claims the systems support 200% PV overloading.

A research group led by Germany’s Fraunhofer ISE has conducted what it describes as the first empirical study on PV-assisted two-stage HP systems in existing multi-family buildings. Its findings show that substantial PV electricity exports result in greater avoided non-renewable primary energy use.
