  • APV-RESOLA – Agrophotovoltaic - A Contribution to Resource-Efficient Land Use

    © Fraunhofer ISE

    Concept of an APV system.

    The costs of ground-mounted PV systems continue to fall. Experts forecast that in about five to eight years, such PV installations will become cost-effective even without the financial support of the Renewable Energy Act (EEG). Decreasing costs spurn on new types of business models for land use and as a result new challenges arise. Increased competition for land use, for example, can cause the rental price for land to rise. The innovation group APV-RESOLA is therefore developing and investigating a new type of PV system that ensures the coexistence of agriculture use and electricity production on the same piece of land. | Duration: 03/2015 - 01/2021

    Prototype of a coil (Ø approx. 70 cm) for wireless energy transfer between stationary charging station and electric vehicle.

    The energy transformation and the accompanying electrification of the transport sector require increased interconnection of the energy systems. High availability in the grid is of great importance when integrating electric vehicles as intelligent consumers and storage devices into the energy industry. Within the scope of the »BiLawE« project, a bidirectional inductive charging system and its economic integration into the electricity grid are realized. New sensors for live object detection, efficient inductive energy transmission (up to 11 kW), and maintenance concepts address the increased requirements on integration into the (semi) public sectors. | Duration: 01/2016 - 06/2019

    Row of thermal solar connectors on a flat roof in the building area Freiburg-Gutleutmatten.

    During this project, the decentralized integration of solar thermal energy plants into a heat supply concept based on a cogeneration unit is examined. The operation of the cogeneration unit is optimized for the best possible interaction with the power grid and the local heating network for a minimization of distribution loss. The central objective of the project is to implement and review the concept and operations management in the demonstration project Freiburg-Gutleutmatten and subsequently derive generally applicable regulations for the long-term utilization of solar thermal energy in comparable residential areas, especially in light of massively changing energy supply structures. | Duration: 06/2013 - 04/2018
