Overcapacity hammering solar stocks
BloombergNEF Senior Analyst Jenny Chase and Aurora Energy Research Renewables Lead Rebecca McManus speak with pv magazine about financial market trends for solar companies and the role of overcapacity as a driver of turbulence in the industry.
Liquid hydrogen test flight could enable long-distance flights
H2FLY claims that a recent three-hour test flight, entirely powered by liquid hydrogen, could lead to sustainable long-range flights fuelled by liquefied, cryogenic hydrogen. Solaris, meanwhile, has started selling hydrogen buses in Italy.
How long do residential solar panels last?
Multiple factors affect the productive lifespan of a residential solar panel. In the first part of this series, we look at the solar panels themselves.
REC launches 470 W heterojunction solar panel with 22.6% efficiency
REC has developed a new series of heterojunction solar panels with efficiencies up to 22.6% and an operating temperature coefficient of -0.24% per degree Celsius.
How to build, finance product stewardship scheme for solar panels
Researchers in Australia have provided a series of recommendations to set up regulatory frameworks for PV module recycling and reuse. They said that, as a rule of thumb, landfill bans, tracking of the panels’ serial numbers, and a clear definition of ownership should always be included in the legislation for end-of-life solar products.
Shell looking to sell Sonnen
Shell, which acquired Sonnen four years ago, is now actively seeking a majority shareholder for the Germany storage system specialist.
China solar module prices dive to record low
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.
Nextracker unveils three next-gen solar racking products
Australia’s most popular mounting solution brand, US company Nextacker, has released a hail stow-ready rack, a terrain following tracker and an irradiance-tracking yield optimiser.
Anode-less redox flow batteries capable of fast cycling
Researchers in the US have demonstrated that replacing the planar lithium anode in a redox mediated lithium-sulfur redox flow battery with a high surface area scaffold enables 10 times faster cycling, up to 10 mA cm−2, without short circuit or voltage instability.
The case for hard carbon-based sodium-ion batteries
Researchers in China have summarised the technical issues hindering the development of hard carbon, which is regarded as the most promising anode for high-performance, commercial sodium-ion batteries.
