Mercedes-Benz presents a vision that transcends the aesthetic: a paint that converts solar light into energy.
The German manufacturer has showcased some of its most promising initiatives aimed at transforming the automotive industry. Among these, one technology stands out, focused on electricity generation directly from the vehicle’s bodywork, marking a significant step towards integrating renewable sources into electric transportation.
Mercedes-Benz’s proposal consists of an innovative solar coating that works as a special paint for electric cars. This material, applied as a layer on the exterior surfaces, converts solar light into energy, adapting seamlessly to any design or inclination of the bodywork, making it highly versatile.
Benefits of paint that converts solar light into energy
In addition to its functionality, this coating offers significant benefits in sustainability and economy. It is made from accessible and non-toxic raw materials, avoiding the use of rare earths and silicon.
According to the manufacturer, its production process is more cost-effective compared to conventional solar panels, and its design facilitates recycling, positioning it as a practical and ecological solution for the future of electric mobility.
The solar paint designed by Mercedes-Benz represents a significant advance in sustainable technology by using innovative materials that differ from those used in conventional solar panels. This coating is manufactured without using rare earths or silicon, making it not only less harmful to the environment but also facilitating its recycling process.
Its ultralight and compact design, with a thickness of just five micrometers and a weight of 50 grams per square meter, does not compromise its energy generation capacity. With an efficiency of 20%, this solution is ideal for maximizing the use of solar energy without adding significant weight to the vehicle.
A step towards sustainability with solar paint
The practical capacity of this technology is illustrated with a specific example: a bodywork equivalent to 118.4 square meters, like that of a medium SUV, could generate enough energy to cover up to 12,900 kilometers per year under optimal conditions.
The solar paint incorporates photovoltaic cells that generate electricity to directly power the high-voltage battery or drive the vehicle’s propulsion system.
This innovative system remains active at all times, even when the car is turned off, allowing for maximum utilization of solar light to increase autonomy and reduce dependence on charging stations.
Factors influencing energy production
The energy production through this solar paint depends on various factors such as the intensity of solar light, shadow conditions, and geographical location.
According to an analysis conducted in Stuttgart, Germany, local drivers who travel an average of 51 kilometers per day could cover 62% of this distance solely with the solar energy generated by the paint. This represents a significant reduction in the need for conventional electrical charging.
In cities with higher solar incidence, the potential of this technology is expected to be even greater. Mercedes-Benz estimates that, under optimal conditions, the solar paint could provide enough energy to cover 100% of daily journeys.
Thanks to its bidirectional charging functionality, the excess energy generated could be redirected to power the household grid, adding sustainable value to the use of this innovation. This advancement not only redefines how electric vehicles manage their energy but also presents an opportunity to optimize energy resources in various regions worldwide.
