How long do residential storage batteries last?
Multiple factors can affect the lifespan of a residential battery energy storage system. We examine the life of batteries in Part 3 of our series.
Residential battery inverter from the US
US storage system provider NeoVolta has developed a battery inverter that provides 32 A of AC output power. It has a storage capacity of 14.4 KWh that can be expanded to 24.0 kWh with the addition of another battery without the need for a second inverter.
Agrivoltaics for strip farming
Vattenfall is leading a Dutch consortium in a research project to assess whether agrivoltaics is also compatible with strip cropping. The company’s head of Solar Development NL, Annemarie Schouten, spoke with pv magazine about the first 0.7 MW pilot project under development in the northern Dutch province of Flevoland.
Lightyear solar car has raised more than $110m this year
The Dutch start-up behind the world’s first commercial grid-independent solar car has generated significant investment this year. Deliveries of the prototype Lightyear One are now set for next summer.
Recycling solar panels: Making the numbers work
NREL researchers said a profitable and sustainable solar panel recycling industry could establish itself by 2032. Here’s how the numbers work.
Agrivoltaics for viticulture
French specialist Sun’Agri installed a pilot facility on five hectares in southern France in 2018. Its goal is to protect the vines from weather hazards and to improve the quality of the wine by lowering its alcohol content. The first harvest took place in mid-September.
Dutch gas giant begins storing hydrogen in underground salt cavern
Operated by Gasunie, the underground storage facility is located near Veendam in the province of Groningen and should be fully operational in 2026. Tests will be run until spring 2022.
Russian scientists achieve 21.1% efficiency in perovskite solar cell via Mie-resonant silicon nanoparticles
A Russian-Italian research group has developed resonant silicon nanoparticles that are claimed to improve the performance of perovskite solar cells. These particles serve as nanoantennae – they catch light and it resonates inside them, which amplifies the cell’s light absorption.
Hybrid PV-thermal modules providing heat source to brine-water heat pumps
Developed by Dutch company UseAllEnergy, the module is fabricated with a heat exchanger placed on the rear side that works as a heat source for a brine-water heat pump. Thanks to this innovation, the heat pump does not need to get heat from a borehole yet can still generate sufficient thermal energy. The solution is claimed to be easy to install and also to be suitable for retrofits.
Solar-powered delivery van with 400 km range
Swedish start-up Clean Motion is seeking to commercialize an electric delivery van that is also powered by IBC solar modules placed on its roof. The vehicle is claimed to have a 400 km range, of which up to 130 km are provided by the PV array.
