About the project

The number of electric vehicles is growing rapidly in Europe and more charging stations and power for charging will be needed. As a result, this will increase the load on the grid. One solution to this is to establish a so-called “Smart grid” which combines electricity use with locally produced solar electricity.

The batteries in the electric vehicles then have the possibility to store solar electricity and relieve the electricity grid when needed. A consortium with participants in Sweden and Norway are now implementing the demonstration project Solarcharge 2020 under the EU ERA-Net Smart Grid Plus program.

In the project, electric vehicle charging and adjacent solar power production will be investigated. Systems for solar charging will be built in full scale in Uppsala and in Tromsø, Norway. The goal is to demonstrate and to evaluate various strategies for large-scale solutions where electric car charging is matched with local production of solar electricity. In addition to increased production of renewable energy, the solution has potential to reduce the load on the power grid. A common requirement specification will be developed to make it easier for municipalities and businesses to buy equipment and technology for the solar charging system. The specification shall be validated for use in most European countries.

The project was initiated by Solelia Greentech AB and implemented in a project consortium with Norwegian and Swedish actors, Uppsala Municipality, Uppsala Parking company (Sweden) and Troms Fylkekommune (Norway). Uppsala University and UiT the Arctic University of Norway will employ a number of researchers for detailed systems analysis of how solar energy is produced and consumed in the systems and how the results and the technology can be scaled up for future large-scale expansions. The Solarcharge 2020 project will be carried out in six phases and will be completed in 2018.

“As solar power production increases, the question of how to positively affect grid variations becomes increasingly critical to grid stability,” says Per Wickman, CEO of Solelia Greentech AB. “This project shows that new high-quality solar electricity supplied to the power system can be used where it is most beneficial, helping maintaining a stable grid.”
