New mounting system for rooftop PV, from Austria

The mounting structure relies on a 5.8m long support rail that does not lie on the roof but is connected directly to a purlin placed below with self-drilling support screws.

Solar module for east-west installations on flat rooftops

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.

Mapping the future of cleaner transportation

Eight key developments are accelerating the advancement of electric vehicles. These range from the improvements in cost and performance of electric vehicle (EV) batteries to hydrogen-powered vehicles.

Minimum solar panel row distance crucial for good soil, vegetation conditions, in solar parks

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.

A new spin on battery manufacturing

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.

Hybrid wind-solar for highways

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.

Ayana Renewable partners Norway’s Greenstat on India’s hydrogen mission

The Bengaluru-based solar and wind energy developer has signed a Memorandum of Understanding with Greenstat Hydrogen India to collaborate on developing projects for green hydrogen production in India.

Flexible solar panel for vehicle-integrated applications

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.

Foldable solar panel for disaster prevention

The portable module has a foldable design with a four-panel structure and a power output of 100 W. It also incorporates a Suncast module that indicates the best height and tilt angle it must have to ensure optimal yield.
