The ReFlex project aims at developing a replicability guideline for the deployment of technologically feasible, market based and user-friendly solutions for smart grids with a high level of flexibility. The focus was put on smart grid pilot projects with high level of renewable energy production, which are effectively and efficiently used locally through mixes of measures from voltage regulation, demand response, energy management and storage. Drawing on the learning experience among ReFlex partners, replicability-guidelines were elaborated to support the demo regions and the wider group of European smart grid stakeholders in deploying and advancing their smart grid initiatives. The project released the ReFlex Guidebook, a document that includes guidelines for the replicability of solutions for flexible smart grids. Weiterlesen

The Swiss company Insolight is taking a whole new approach to creating high-efficiency solar modules for the rooftop market. Its patented optical system concentrates light onto an array of tiny spacegrade multi-junction photovoltaic cells. While today’s rooftop standard modules typically show an efficiency of 17-19%, Insolight’s pre-production module has been validated at an impressive 29% by the Universidad Politécinica de Madrid (IES-UPM), two years after a first record on a lab prototype. The company based at the EPFL Innovation Park has taken a decisive step towards industrialization with its first pre-production full-size series, cost-effective and compatible with existing assembly equipment.
