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.
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.
Photovoltaic signboard with 18.5% efficiency
Dansk Solenergi, a Danish building-integrated PV specialist, has launched a round, 95 W solar module that works as a PV signboard. Its 35 solar cells, which remain hidden behind an image of Earth, have an efficiency of 18.5%.
Weekend read: Solar tops the bill
The US Inflation Reduction Act of 2022 sets aside $369 billion to decarbonize the economy and respond to climate change. pv magazine USA’s Anne Fischer and Ryan Kennedy report on the boost the landmark legislation is expected to provide to solar and battery deployment and manufacturing.
Virtual power plant to trade grid-stability services in New Zealand
New Zealand’s solarZero says it aims to provide fast, sustained reserves with its virtual power plant (VPP) of 10,000 household battery systems. Meridian Energy, meanwhile, has secured approval for a 100 MW battery energy storage system – the country’s largest such system to date.
Neighborhood battery plan to maximize solar benefits in Australia
The government of the Australian state of Victoria has unveiled an ambitious plan to install 100 battery energy storage systems by the end of 2026, as part of a broader strategy to support the rollout of more rooftop solar.
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.
Hydrogen-producing rooftop solar panels nearing commercialization
KU Leuven researchers have developed rooftop panels that capture both solar power and water from the air. Like traditional PV modules, hydrogen panels are also connected, but via gas tubes instead of electric cables. The researchers are now preparing to bring the tech to the mass market via a spinoff company.
Rooftop PV performance during heatwaves
Chinese researchers have assessed the impact of residential rooftop PV arrays on energy use and surrounding air temperatures during extreme heatwaves. They found that panels with higher conversion efficiencies achieved the best results.
