Austrian solar developer Sunlumo announced that its full plastic solar collector is now the first 100 % plastic collector from Europe awarded with the Solar Keymark certification.

“This certificate stands for reliable quality and safety,” Sunlumo CEO Robert Buchinger declares. Solar Keymark is a quality certificate for solar collectors and solar thermal systems, that is valid throughout Europe.

To be recorded as bearing Solar Keymark certification, the One World Solar Collector had to pass the full test, as specified in the EN12975 standard in force, and to withstand quality assurance in manufacturing. The pilot series was manufactured by licensee One Sun One World GmbH. Their quality management level meets the requirements of EN ISO 9000. Both the product and the manufacturing process are regularly checked by independent institutions. Every product alteration must be recorded with the institution.

Product design to reduce material input

One of the most distinguished characteristic of polymer collectors is the weight. A normal metal based collector weighs around 15 to 20 kg/m². Sunlumo’s plastic-based One World Solar Collector only weighs 8.1 kg. Among other things, the tests concerned internal pressure resistance, high temperature resistance, internal and external thermal shock, impact strength, heating performance, over-temperature protection, and pressure resistance. It was the first time that an external testing institute officially confirmed the suitability of this new collector.

Turnkey factories for producing polymer-based collectors

Sunlumo issues licenses for the realisation of the innovative One World Solar Collector and also supplies turnkey factories. The factories are available with different levels of automation. Production sites can be customised to clients’ needs, with annual production capacities ranging from 100 to 350 MWth.

For the secure integration of solar parks on a gigawatt scale, grid operators need particularly accurate predictions of power generation. The German-based company energy & meteo systems is already forecasting the generation capacity of large parts of several gigawatt parks and has now also acquired operators of the world's second largest solar park Pavagada in India as customers.

Renewables covered around 52 percent of gross power consumed in Germany during the first quarter of 2020. This all-time high was driven by a combination of one-off events. Preliminary calculations by the Centre for Solar Energy and Hydrogen Research Baden-Württemberg (ZSW) and the German Federal Association of Energy and Water Management (BDEW) yielded this figure. February’s record winds were followed by an unusually sunny March. Power consumption was also down by one percent from the same period last year.

According to the General Administrative Regulation (German: AVV) for the marking of aviation obstacles, infrared light will be mandatory for many wind turbines as additional navigation lighting. The infrared light developed for this purpose by former Reetec, now Robur Wind, has been certified by the responsible authorities.

The smarter E Europe and its four energy exhibitions Intersolar Europe, Power2Drive Europe, ees Europe and EM-Power will not take place this year. On account of the increasing spread of the coronavirus (SARS-CoV-2) worldwide and in response to recommendations from the German federal government as well as the Bavarian state government, the organizers have decided to cancel the exhibitions and the accompanying conferences originally set to take place from June 16–19, 2020. The smarter E Europe will take place again from June 9–11, 2021.
