Novel soiling loss measurement system for PV installations
An international research group has developed new technology to measure soiling losses in PV installations, by using a simple pocket light. They said the new system offers similar performance to their reference devices.
Is hydrogen about to have its solar moment?
As Longi and other solar manufacturers kick off massive growth in hydrogen generation capacity, expect large price decreases resulting from steep learning curves, echoing the rapid advances experienced by the solar power industry since the 1970s.
Roadmap to achieve CIGS solar modules with efficiencies above 20%
Japanese scientists have described the steps that need to be taken to improve the average efficiency of CIGS solar modules, from around 18.5% at present to more than 20%. They presented all of the critical technical factors that are currently holding the tech back from broader market adoption.
Hydrogen, carbon prices and electricity markets
The hydrogen economy, particularly green hydrogen, has a long growth path ahead.
New algorithm to identify underperforming strings in PV systems
German researchers have created an algorithm to predict and identify string yield losses or underperforming strings without additional weather data. It could be used to inspect modules, strings, arrays, inverters, and transformers.
US battery maker unveils solid-state storage systems for residential applications
Amptricity has emerged from stealth mode with plans to manufacture solid-state batteries for residential and commercial installations.
French startup reveals rooftop system with PV panels, mini wind turbines
French startup Unéole has developed a rooftop system that combines solar and silent wind turbines. It claims its system can produce 40% more energy than standalone rooftop solar arrays. It is now testing the device, with plans to commercialize it by 2023.
Ernst & Young again ranks India as world’s most attractive solar market
India is the top market for solar investment, according to the latest edition of Ernst & Young’s renewables attractiveness index. Spain, Germany and the United States are the top three markets for corporate power purchase agreements (PPAs).
Tipping point for African C&I solar
With installers who cater to African businesses making the headlines this year, Jasper Graf von Hardenberg – whose C&I solar business was recently bought by Shell – explains here how the story of the continent’s commercial and industrial (C&I) solar segment was far from an overnight success.
World’s first utility-scale, rock-based storage facility goes online in Italy
Enel is testing a 24 MWh thermal energy storage system that could be used for seasonal renewables storage. The facility uses rocks that store excess energy as heat, then releases that heat to generate steam for electricity.
