AMG Advanced Metallurgical Group has energized its first hybrid storage system based on lithium-ion batteries and vanadium redox flow batteries in Germany. The system reportedly combines the advantages and electrochemical properties of both storage technologies.

Scientists in Thailand have used microwaves to separate broken glass from PV panels. The process can be performed at temperatures ranging from 45 C to 55 C.

Toshiba and Marubeni have revealed plans to build commercial projects based on thermal storage technology using rocks. They have set up a demonstrator with 100 kWh of storage capacity and a relatively high heat storage density.

Italian scientists have looked at how non-linear degradation curves could affect the profitability of large-scale solar projects. They found that full substitution of the modules after 10 years could be justified if the performance loss rate was higher than 1% per year.

Sunova Solar is offering five versions of its new solar panels, with power outputs from 555 W to 575 W and efficiencies ranging from 21.4% to 22.2%. They have a temperature coefficient of -0.31% per degree Celsius.

The Turkish government has published long-awaited rules for energy storage in its official journal. Local solar association Günder said the first projects will be approved in the middle of 2023.

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).

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.

Winaico’s new PV modules are based on monocrystalline half-cells and a 10-busbar design, with a power conversion efficiency of 21.0%.

The Romanian government has reportedly rejected almost all permit requests for large-scale solar projects. Law firm Vlăsceanu, Nyerges & Partners claims that the authorities are misinterpreting new rules designed to streamline the permitting process for small projects and support solar on agricultural land.
