Developments in the Sector
To have solar-powered electric cars in Australia, several key technologies and infrastructure developments would need to be implemented and improved:
Efficient Solar Panels: The first requirement is highly efficient solar panels capable of converting sunlight into electricity with minimal loss. These panels must be lightweight and flexible enough to be integrated into the car’s design without compromising performance or aesthetics.
Advanced Battery Technology: Solar-powered electric vehicles would necessitate advanced batteries capable of storing the electricity generated by solar panels. These solar batteries require high energy density, fast charging, and a long lifespan. For example, Solid-state and lithium-sulphur batteries could meet these requirements.
Smart Energy Management Systems optimize the use of solar panel-generated electricity in vehicles for maximum efficiency. They would also manage the battery’s charging and discharging to maximise lifespan.
Lightweight Materials: To maximise the efficiency of solar-powered electric vehicles, lightweight materials such as carbon fibre and advanced composites could be used in their design. Less energy needed to move the car, so more solar power can be used for driving.
Solar Charging Infrastructure: A network of solar charging stations and the solar panels on the cars themselves would be beneficial. These stations could produce and store solar power in large batteries, allowing electric vehicles to charge even when the sun isn’t shining.
Vehicle-to-Grid (V2G) Technology: This enables electric vehicles to draw power from and feed power back into the grid. In the context of solar-powered electric vehicles, this could imply that excess solar electricity generated by the vehicle could be fed back into the grid, increasing the system’s sustainability.
Regenerative Braking: This technology, which is already used in many electric and hybrid vehicles, allows the car to recover energy while braking and recharge the battery. This would improve the efficiency of solar-powered electric vehicles even more.
By implementing and improving these technologies, Australia has the potential to set the standard for the development and adoption of solar-powered electric vehicles. However, significant investment in research and development, supportive government policies, and public acceptance would be required.
