Self-sufficient solar parking lot in Dresden

The first self-sufficient parking lot is located on Scharfenberger Straße in Dresden. It has six parking spaces shelves under a solar carport with charging options and 42 additional parking lots. The internet of things platform of the Dresden-based company Kiwigrid, in conjunction with a Solarwatt photovoltaic system, ensures that solar modules, electricity storage, charging stations and the public grid communicate with each other. The charging stations and the LED lighting system are supplied solely with solar energy.

In the ideal case, this system can autonomously cover its own energy consumption completely with solar energy. Power from the grid is only used when the self-generated solar energy is expended. "This intelligent combination of renewable energy generation, electricity storage and the grid is an important step on the way to a more environmentally friendly energy and transport world," says Solarwatt CEO Detlef Neuhaus.

Intelligent city of the future

"Parking spaces that allow the charging of electric vehicles to 100 percent from solar energy are a component of the intelligent city of the future. Together with our partners from Dresden, we will show how they work and what potential they can bring to a city like Dresden, "explains Kiwigrid CEO Matthias Hertel.

Even surrounding buildings benefit from solar

During the year, the photovoltaic system in the parking lot generates more energy than it needs. However, it is not planned to feed the surplus energy into the public grid. On the contrary, the solar power will be consumed on site in order to relieve the grid. In the future, adjacent buildings can as well benefit from the environmentally friendly solar power. (HCN)
