Photovoltaics for vapor compression refrigeration
Scientists in China have developed a PV-driven direct-drive refrigeration system for electronic device cooling. The proposed system has so far provided low exergy levels, but its costs are much lower than those of conventional vapor compression refrigeration technologies.
Sinovoltaics updates financial stability ranking of PV module manufacturers
The latest Sinovoltaics financial stability report ranking lists Tainergy, Eterbright, First Solar, Era Solar, and TSEC as the top five module makers. There was a slight reshuffling in the top ten, and seven new manufacturers were added to the ranking.
VSole presents wall-mount residential hybrid inverters
Indian manufacturer VSole has introduced single-phase hybrid inverters 3 kW to 6 kW with power output ratings. The inverters reportedly allow uninterrupted power to the connected loads, with a UPS-level switching time of four milliseconds.
The Hydrogen Stream: EU hydrogen tender ends with bids below €0.50/kg
The European Commission has selected the winners of European Hydrogen Bank’s first auction, with bids coming in below €0.50 ($0.54)/kg, while Chile and Namibia have revealed new hydrogen plans.
Chinese PV Industry Brief: GCL Technology posts 2023 revenue dip
GCL Technology says revenue and profits fell in 2023 due to losses on certain assets, higher financing costs, and an uptick in R&D spending.
Italy’s EU-made PV incentives raise specter of Chinese opposition
A World Trade Organization (WTO) official and several Italian lawyers recently spoke with pv magazine Italy about the timing of a potential Chinese legal challenge against Italy’s new solar measures, which exclusively provide incentives for high-performance PV modules produced in the European Union.
The case for utility-scale storage in the Middle East
In a recent chat with pv magazine, Yasser Zaidan, senior sales manager for the Middle East at JinkoSolar, described the trajectory of the large-scale storage business in the main markets of the Middle East.
Belgian grid operator releases tool to help residential PV system owners detect inverter failures
The so-called “network checker” will allow residential PV customers in Belgium to check if there have been any inverter failures in their local area. It comes after Belgian grid operator Fluvius launched a compensation scheme for those who are not reconnected within 30 working days of a curtailment.
NREL interactive chart of solar cell efficiency now including ‘hybrid tandems’
The new cell category includes perovskite/silicon, perovskite/CIGS, III-V/silicon and perovskite/organic tandem PV devices. It will list the absolute record efficiency for all-perovskite, two-terminal tandems regardless of the number of junctions.
Climate change to drive value of rooftop solar
University of Michigan researchers have found that the value of rooftop solar will increase by between 5% and 15% by the mid-century across a range of US cities under moderate climate change, and by up to 20% by the end of the century.
