Researchers have modeled a hybrid financing scheme combining contracted and merchant components to improve the bankability of PV-battery energy storage system (PV-BESS) assets, using a Bayesian LSTM forecast integrated with a MILP optimization model to assess performance.

Scientists in China have developed a novel missingness-aware power forecasting method that leverages signal decomposition, multi-scale covariate interaction, and multi-domain collaborative transfer learning. The approach reportedly improves average forecasting accuracy by 15.3%.

The Japanese car maker announced it will show a prototype extendable solar PV rooftop onboard a Nissan Sakura Kei at an upcoming mobility industry event in Japan.

Janta Power closed $5.5 million in seed funding to develop its vertical solar tower, with pilot programs already underway in major global airports like Dallas-Fort Worth and Munich International Airport.

At the Modules and Material Worksop in Konstanz, organized by solar manufacturing engineering company RCT Solutions and ICS Konstanz, experts from the European PV equipment production industry gathered to discuss the current and future trajectory of manufacturing costs, technology advancements and equipment and raw material capabilities. RCT Solutions CEO, Peter Fath, told pv magazine that a European 1 GW module assembly facility using the same supply chain as Chinese Tier 1 counterparts could reach module manufacturing costs of €0.11-0.12/W.

A novel technical textile integrating 150 organic photovoltaic solar PV devices was demonstrated in a pavilion installation at the Dutch Design Week 2025 in Eindhoven, Netherlands this month.

Japan’s SoftBank Corp. has launched a four-year program backed by the New Energy and Industrial Technology Development Organization (NEDO) to advance high-density batteries and high-efficiency solar cells for high-altitude platform station aircraft.

Algerian researchers have built a single-stage solar and battery desalination system for brackish water that uses a hybrid spotted hyena optimizer and maximum power point tracking (MPPT) algorithm to improve efficiency. Simulations and real-time tests showed high performance, steady water output, and low salinity under changing solar conditions.

The Chinese manufacturer debuted split-unit 836 kWh system at SNEC ES+ 2025, targeting flexible, safe overseas commercial deployments.

Australian energy storage manufacturer RedEarth Energy Storage is set to bring its Australian-made vehicle-to-grid electric vehicle charge to market, and has also released two next generation products from its smart energy ecosystem.
