A German PV system owner has developed a simple solution intended at preventing the birds from nesting under the modules.
A Swiss start-up has created a containerised movable PV system that is designed to be easily relocated to allow the use of solar energy in locations where a fixed installation is not an option. The solution is based on a racking technology which can include two racks able to host up to 30 solar panels.
The 100% solar-powered boat will be tested in a 9,000 nautical mile expedition from Chile to Australia that is set to start in December. The vessel is equipped with an 11 kW PV system built with heterojunction modules provided by Russian manufacturer Hevel Solar.
The 50 kW version of the new inverter features an efficiency of 98.6% and a European efficiency of 98.1%. It can be deployed with a decentralised approach, next to the PV modules, or centralised, at the grid connection point.
Spanish PV project developer Gransolar is planning to build a large-scale green hydrogen production plant in the Port of Almería, in southern Spain.
A prototype of a cement-based battery has been developed in Sweden for potential applications in buildings. Its creators claim it could become a solution to store electricity from rooftop PV and they do not exclude that it could also be used for the storage of large-scale renewables.
Production on the new module, called Q.Tron, is expected to begin this year. The product is described as an evolution of the company’s Q.antum cell technology.
The most powerful of the two products has a power output of up to 380 W and an efficiency of 20.4%. For both panels, the temperature coefficient is -0.37%. The German manufacturer said the modules are produced at its manufacturing facility in Dresden.
Graphite’s pivotal role in electric-vehicle battery technology is coming under increasing scrutiny. Graphite is almost exclusively produced in China, and while the processing of the mineral poses serious environmental issues, the alternatives appear costly. Ian Morse looks at what’s next for critical graphite supplies.
Hydrogen and hydrogen-based fuels will not be able to move forward fast enough to replace fossil fuels and tackle climate change, according to a German-Swiss research team that claims direct electrification alternatives are cheaper and easier to implement. The scientists cite too-high prices, short-term scarcity and long-term uncertainty, as the main reasons for their skepticism, which has caused a stir in academic circles.
