Dutch startup Solarge has developed a 500 W panel that weighs 50% less than conventional glass-backsheet modules. The new product can be fixed to rooftops with roofing anchors, which eliminates the need for ballast, according to the manufacturer.

The result was confirmed by Germany’s Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE). The cell was fabricated through a low-temperature co-evaporation method for the growth of the light-absorbing CIGS semiconductor thin film.

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.

Manufacturer Sunlight plans to invest €30 million to add 1.3 GWh of annual production capacity of lead-acid products by the third quarter of next year. The company will also devote €20 million to expanding its lithium-ion battery assembly lines.

A Dutch research group has shown that south-oriented solar parks offer better environmental conditions for soil and vegetation than east-west oriented facilities. According to their findings, a distance between panel rows of at least 1.5 times panel height is crucial to favor ideal plant growth and soil functioning.

Oceans of Energy is planning to deploy a 3 MW off-shore floating PV array in the North Sea.

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.

Scientists in the UK have explained the mechanism behind chlorine used to boost the efficiency of cadmium telluride thin-film solar cells. With new understanding of the chemical processes at work in the manufacturing process, the group hopes to be able to push for cell efficiencies beyond 25%.
