Zucchetti unveils 5 kWh high-voltage battery for three-phase storage applications
Zucchetti’s new battery features a nominal capacity of 5.12 kWh and a nominal voltage of 400 V. It says it is suitable for C&I and residential PV systems.
Assessment of hydrogen-induced contact resistance in TOPCon solar cells
Researchers have looked at how hydrogen-induced contact resistance could help to reduce changes in series resistance, in either TOPCon or PERC solar cells. They said degradation occurs purely at the n-type silicon-to-silver (Ag) contact on both cell architectures.
All-perovskite tandem solar cell with 27.4% efficiency, high voltage
A US-Canadian research group has built an all-perovskite tandem PV device with a record-breaking open-circuit voltage of 2.19 eV, which they achieved by reducing recombination at the electron transport layer.
Denmark, Sweden, Finland could add 12.8 GW of solar by 2030
The Nordic region is set to become a European renewables powerhouse, according to Rystad Energy. It says Finland, Sweden and Denmark could collectively install up to 12.8 GW of new solar by 2030.
Sun-tracking floating solar islands from Portugal
Portugal-based Solaris Float has developed a swiveling floating solar platform with one- or two-axis tracking. It has installed its first project on a lake in the Netherlands. The project consists of 130 PV modules on a single-axis tracker, with an installed capacity of 50.7 kW.
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.
BayWa, Velux sign Europe’s first agrivoltaics-linked PPA
Germany’s BayWa r.e. and Denmark’s Velux have announced the first agrivoltaic corporate power purchase agreement (PPA) in Europe. BayWa will build two solar parks in Spain to power Velux’s operations, with capacities of 60 MWp and 56 MWp. One of them will partly be an agricultural PV project.
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.
Italy’s Key Energy positions agrivoltaics, utility storage as new market drivers
The latest edition of Key Energy, Italy’s top solar event, shows that the nation is once again poised for growth. It also shows that incentive schemes can turn agrivoltaics and large-scale storage into market drivers like rooftop and ground-mounted PV.
JinkoSolar claims 23.86% efficiency for n-type, TOPCon monocrystalline panel
JinkoSolar’s newest PV module has an efficiency rating of 23.86%. It is based on its TOPCon mono cell tech, which achieved a record efficiency of 26.1% in October, as confirmed by TÜV Rheinland.
