Solar charging infrastructure arrives (

19 September 2022

(Bsw) More than 25 percent of wall boxes for charging e-cars are already installed together with solar panels and solar energy storage. In addition, a quarter of the Wallbox customers had previously had solar systems in operation. Further insight into the hotly debated expansion of the charging infrastructure in Germany is provided by the new study ‘Installation Radar Charging Infrastructure’, created jointly by the market research institute Eupd Research, the German Solar Industry Association (BSW) and the mobility trade fair Power2Drive.

The study fills a gap that other publications are currently unable to fill: It sheds light on infrastructure expansion and the main challenges associated with it from the perspective of the installers doing the work.

Business area of ​​central importance
The expansion of the charging infrastructure is a business area of ​​central importance for the solar cell industry. The installer survey, on which the survey is based, provides both private and political decision-makers with important insight into the challenges of the developing market (e.g. purchasing, sales channels, training) as well as into the preferences of the implementing actors. “Solar energy from your own roof is already considered to be the cheapest driving power available. Solar energy and electromobility are therefore a dynamic dream couple, which makes more and more people switch to electric cars,” says Bsw CEO Carsten Körnig, emphasizing the synergies between solar energy and electromobility.

Significantly more speed is required
However, in order for further demand for electric cars not to be slowed down, the expansion of the charging infrastructure must also be accelerated significantly. The number of electric cars and available charging points has decoupled in recent years to a ratio of 12:1 by the end of 2021. Current data from the German Federal Motor Transport Authority (Kba) and the German Federal Network Agency (Bnetza) indicate that this trend will also continue in the year 2022, continues. “We need much more speed, especially when it comes to expanding the public charging infrastructure. Politicians should contribute by removing unnecessary market barriers and outdated bureaucracy, for example in procurement and in calibration legislation,” warns Körnig.

The survey results show which factors in this context are decisive for the future business development of plumbing companies and related professions. Eupd study leader Christine Koch: “This includes the availability of the necessary components, fast delivery times, well-founded product information and training, as well as simple procurement.”

Already arrived on the market
According to Martin Ammon, managing director at Eupd Research, the installer survey shows that the combination of ‘PV system + power storage + wallbox’ has already entered the market. Consumers are betting that in the future they will be able to generate their driving force reliably and cheaply from solar energy, with additional solar energy storage optimizing the share of usable solar energy for the electric car.

Power2Drive Europe is the international trade fair for charging infrastructure and electromobility. The fair’s focus under the motto ‘Charging the future of mobility!’ are charging systems and electric cars as well as mobility services. Power2Drive Europe will take place from 14 to 16 June 2023 at the Munich Exhibition Center.
