Energetica modules give high-performance e-mobile charging park in Germany the power they need.

The aim of the project constructor Opel Energy was to create a charging park that would be the first of its kind in Germany: The electric vehicles were to be refueled exclusively with solar energy generated on site.

For this purpose, drivers currently have ten charging stations at the Wiesbaden/Mainz retail park, each with two charging points.

Around 80 percent of the energy used for this can currently be generated on site. If Opel Energy and plant operator Sun2Charge have their way, it should soon be 100 percent, at least in the sunny summer months.

Energetica has delivered 2,300 of its robust, high-performance “workhorses”, namely the Classic M HC 380 solar modules, with a total output of 874 MWp. They produce around 900,000 kWh of solar power per year. That’s enough for around 5 million kilometers driven by car.

The charging park is designed as an “energy island” and is self-sufficient: the electricity is not fed into the public grid, but stored on site. Two battery inverters with a total output of 560 KW direct the solar energy into battery storage with a capacity of 660 KWh, enough to supply around 100 two-person households with electricity for a day. This also guarantees charging of the car at night or in the event of a power failure.

The figures also speak for themselves in other respects: 14 solar inverters with a connected load of 780 KW are doing their job. 1.5 km of energy cables, 1 km of data cables and 16 km of PV cables were installed.
