A call for grant proposals has been promised this month, with the bloc’s executive yesterday firing the gun on a separate exercise related to cross-border EU energy infrastructure projects.

The frameless design of the 50 kW facade was made possible by a concealed suspension technology that, according to its creators, eliminates the need for additional edging at the edge of the module. The installation was built with 135 W CIGS solar modules.

Switzerland-based Energy Pier has developed a new concept for hybrid-wind solar projects located along highways. The proposed solution combines a rooftop PV system with small scale wind generators that are installed on both sides of the supporting pillars of the system.

Scientists in Germany developed a new process for manufacturing battery electrodes, that they say could be both more cost effective and environmentally friendly compared to current technologies. The technique could be applied to a range of different battery materials/chemistries and its creators say they are in discussion with a number of battery cell manufacturers regarding pilot production.

Called SolFlex, the frameless panel is based on 22%-efficient solar cells and is designed for high, one-sided heat load. The standard product measures 100x100x2.9cm, weighs in at 3.4kg, and has a power output of 170 W.

German solar company Polarstern sees many performance-enhancing effects when photovoltaic systems are combined with green roofs. These are provided by cooling, dust absorption and reflective behavior, which are favored by the plants on the roof.

Designed by German provider IBC Solar, the mounting structure can accommodate modules with lengths from 1,500 to 2,100mm and widths from 980 to 1,150mm. It comes with floor rails with pre-mounted construction protection mats and integrated cable ducts for up to 28 6mm² cables.

In the first seven months of the year, the country deployed 3.2 GW of PV, which compares to 2.8 GW a year earlier.

A number of Fraunhofer institutes in Germany want to make green hydrogen more cost-competitive and are working to identify the best and most economical processes for the production of electrolyzers. They intend to build a digital library of future-proof electrolyser manufacturing processes with which the investment costs and even the return on investment can be determined in advance depending on the planned production volume.

The panel is based on 14.9%-efficient organic PV cells with a surface of 1.1 cm2 that the same research group unveiled in September 2020. The solar cells were interconnected using laser structuring.
