Anyone who consistently thinks through the transformation of energy supply to climate-friendly technologies must not stop at the transport sector. On the contrary: globally, large parts of CO2 emissions are still attributable to transport. There is still a lot of untapped potential for climate protection – and photovoltaics plays a central role in this. In private transport, pure battery technology is increasingly establishing itself as an efficient and technologically mature form of drive. However, the electrification of car fleets only makes ecological sense if the vehicles are “refuelled” cleanly with solar power or other renewable energies.
So if you consistently rely on green electricity for electromobility, you can exploit further synergy effects with the car itself. The batteries in the vehicles, which now have capacities of up to 100 kWh, can also be used as mobile power storage units. More and more car manufacturers are enabling their vehicles for so-called bidirectional charging. Here, the car owner or a network operator with data access to the vehicle can decide when and whether a full battery should be used, for example, to compensate for local green electricity bottlenecks in the low-voltage range. This technology can also make a lot of sense economically. In the future, electricity prices may also fluctuate significantly at different times of the day due to fluctuating demand. Coupled with intelligent software, it will be possible to decide when the batteries in vehicles should take up solar power and when they should feed it back into the local grid. Ultimately, solar electromobility is a classic win-win situation for the climate, the energy turnaround and securing affordable, individual mobility in the 21st century.
