Stochastic optimization for PV-powered EV charging stations
Scientists have developed a new optimization approach that combines both day-ahead optimization and real-time optimization to improve operations of PV-driven EV charging stations. The framework is based on the autoregressive moving average and the Latin hypercube sampling models.
Xpanner launches robotic automation kit to retrofit solar pile drivers
The U.S. startup offers a new kit to integrate robotic automation with existing equipment.
The Hydrogen Stream: Japanese researchers develop low-temperature hydrogen battery
Institute of Science Tokyo researchers proposed a battery with magnesium hydride (MgH2) as the anode and hydrogen (H2) gas as the cathode. Meanwhile, researchers at Chung-Ang University proposed chloride-resistant ruthenium (Ru)-based nanocatalysts for direct electrolysis and hydrogen production from seawater.
IPVF testing new perovskite solar PV testing platform from Ecoprogetti
The French research institute has added to its perovskite solar cell and module pilot line an Ecoprogetti integrated testing platform that combines a solar simulator with advanced electroluminescence (EL) analysis.
BYD unveils 14.5 MWh storage system, world’s largest yet
China’s EV giant has unveiled the 14.5 MWh DC “Haohan” single-unit DC block with record-breaking capacity to challenge next-generation energy storage market.
Tiny pinholes can lead to device failure in perovskite solar cells
Researchers in the United States have found microscopic pinholes in perovskites are responsible for the breakdown of such solar cells when under reverse bias conditions. They say the findings should push scientists and engineers to prioritize the production of pinhole-free films to make perovskites more robust and stable.
China polysilicon prices climb 50.7% from July low despite growing inventories
In a new weekly update for pv magazine, OPIS, a Dow Jones company, provides a quick look at the main price trends in the global PV industry.
Hail damage to solar projects: 1% of filed claims, but over 50% of total losses
Hail damage has become a real headache for project developers in the United States, where growing deployment has increased exposure to weather-related risk. As project owners seek to limit the impact of hail on their bottom line, innovations in tracking systems and insurance can help.
AlphaESS releases liquid-cooled ESS for commercial, industrial use
The Chinese storage manufacturer said its new energy storage system has a capacity of 261 kWh per cabinet. It can be expanded up to 50 units in parallel, scaling to multi-MWh projects.
Making the business case for solar-plus-storage with heat-pumps in Japan
A Japanese research team has evaluated the affordability of photovoltaic-battery systems featuring heat-pump water heaters and air conditioning units across nine regions of Japan. They analyzed three price policies and two loan types, identifiying a tradeoff between net demand and cost according to the capacity of the solar-plus-storage system.
