Chinese researchers have proposed a new methodology for designing utility-scale solar power projects in mountainous regions. They simulated a 386.4 MW solar farm near Pu’er, a city in southern China located 1,037 meters above sea level.

Japan’s Ministry of Land, Infrastructure, Transport and Tourism (MLIT) has started accepting submissions for new road-surface PV technologies, with field verification planned in pedestrian areas at roadside stations to test performance and electricity use ahead of societal implementation.

AirWater and Luxor Solar K.K. have launched a 178 kW vertical PV system at a Tottori parking lot, operating under an on-site PPA. The Verpa-based system, a first for the San’in region, maximizes space, avoids snow damage, and reportedly delivers power equivalent to rooftop solar installations.

Chinese module manufacturer Longi says its Hi-MO 9 series with HPBC 2.0 cells achieved watt-for-watt power gains of 1.21% to 3.92% in real-world tests across multiple countries and climates, lowering the levelized cost of electricity (LCOE) compared with mainstream tunnel-oxide passivated contact (TOPCon) modules.

Solar and storage industry leaders from China and Europe gathered in Germany this week to advance cross-border partnerships, launch a bilateral storage collaboration platform, and coordinate strategies for scaling PV and battery deployment amid surging demand, grid pressures, and intensifying market competition.

India added 6.1 GW of open-access solar capacity in the first nine months of 2025, a 13% increase from the same period in 2024, according to the Mercom India Solar Open Access Market Report.

Researchers in China developed a new compressed air energy storage system that uses flooded roadways in abandoned coal mines to store compressed air and heat for nighttime power generation. Simulations show the design can achieve 71.5% thermal efficiency, stable performance, and higher energy density at greater depths, with minimal long-term impact from air leakage.

The Japanese electronics manufacturer is testing its glass-based perovskite solar PV technology in office windows made by YKK AP, a construction and building materials company.

The Southern Johor Renewable Energy Corridor (SJREC) forms part of a $6 billion project developing a 2,000 kilometer-squared hybrid solar and battery energy storage system zone set to connect South East Asia.

A TÜV Nord-certified white paper demonstrating JA Solar’s DesertBlue module series says the modules, which are specifically designed for desert regions and wastelands, transcend industry benchmarks and offer an optimized levelized cost of electricity.
