Floating PV for water pumping, desalination
An irrigation community has built a 786 kW floating solar array on a small water reservoir in Murcia, Spain. The facility will provide power for a solar water pumping system, a desalination unit, and the community itself.
NREL updates interactive chart of solar cell efficiency
The US National Renewable Energy Laboratory (NREL) has released a new, interactive version of its research cell efficiency chart for a range of PV technologies.
Longi claims world’s highest efficiency for silicon solar cells
Longi said it has achieved a 26.81% efficiency rating for an unspecified heterojunction solar cell, as confirmed by Germany’s Institute for Solar Energy Research Hamelin (ISFH).
Elusive longevity
The expected lifetime of PV inverters is significantly shorter than that of modules. In many projects, inverter replacement is included in financial calculations from the start, despite the high costs. Research is being conducted into the causes of faults to develop more durable inverters and components. But plant design can already improve the lifespan of inverters in use today, reports pv magazine Germany’s Marian Willuhn.
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.
