Power from the sun

Fraunhofer-Institut für Solare Energiesysteme ISE


The Fraunhofer Institute for Solar Energy Systems ISE conducts research on the technology needed to supply energy efficiently and on an environmentally sound basis in industrialised, threshold and developing countries. To this purpose, the Institute develops systems, components, materials and processes in the areas of the thermal use of solar energy, solar building, solar cells, electrical power supplies, chemical energy conversion, energy storage and the rational use of energy.

The Institute's work ranges from fundamental scientific research relating to solar energy applications, through the development of production technology and prototypes, to the construction of demonstration systems. The Institute plans, advises and provides know-how and technical facilities as services.

Polymer Materials Make Solar Thermal Systems More Sustainable – Researchers Prove Environmental and Economic Potential
Feb 25, 2015

Within the ExKoll project, the Durability Analysis Group at Fraunhofer ISE investigated the economic feasibility of polymer collectors and performed life-cycle analyses. The experts found that in comparison to standard flat collectors, mass-produced polymer collectors perform better economically and ecologically.

Hybrid Storage Offers Great Potential

Fraunhofer ISE has successfully tested a new concept called “hybrid storage.” In an agent-based operating system (ABOS), thousands of batteries and heat storage systems are aggregated to a virtual storage system. As decentralized control systems the agents coordinate the individual local storage operation. The storage capacity is aggregated for an integrated distribution grid operation. The agent-based operation-system has been developed and tested within the SmartEnergyLab at Fraunhofer ISE.

Solar energy emerging as cheapest power source in many parts of the world

February 24, 2015

According to a study by the Fraunhofer Institute for Solar Energy Systems ISE commissioned by Agora Energiewende, solar energy will become the cheapest power source in many parts of the world. By 2025, solar power in sunny regions will be cheaper than power from coal or gas.
