German automaker presents innovative photovoltaic coating concept, reinforcing its commitment to sustainability and pointing to a future of solar-powered cars.
Mercedes-Benz is once again pushing the envelope in its pursuit of more sustainable and innovative technologies. This time, the German automaker has unveiled a revolutionary concept that promises to change the game: the solar paint, a photovoltaic coating that transforms sunlight into energy. This bold idea not only reinforces Mercedes-Benz’s commitment to sustainability, but also points to a future where solar energy is integrated directly into the bodywork of vehicles.
What is Mercedes-Benz solar paint?
Solar paint is a photovoltaic coating designed to capture and convert sunlight into usable energy. Made with an ultra-thin layer of just 5 micrometers — comparable to the thickness of a bacterium — this technology can be applied to virtually any exterior surface of a vehicle. It is protected by a special layer of nanoparticle-based paint, which allows 94% of the sun's energy to pass through the surface to be captured by the solar modules.
This innovation allows the coating to be lightweight, weighing just 50 grams per square meter, and highly efficient, with a conversion rate of 20%. To give you an idea, an average vehicle with 11 m² of surface covered by this paint can generate enough energy to travel up to 12.000 km per year, depending on the region's solar incidence.

A new step by Mercedes-Benz in solar energy
Mercedes-Benz is no stranger to solar energy. A few years ago, the company partnered with Fraunhofer Institute for Solar Energy Systems ISE to develop a solar roof for the concept Vision EQXX, using silicon cells. But solar paint is an even more impressive advancement. Unlike traditional solar roofs, it is cheaper to produce, does not use silicon or rare earth elements, and is made from non-toxic and recyclable raw materials.
This means that, in addition to being sustainable, Mercedes-Benz solar paint can be an economically viable solution to democratize the use of solar energy in the automotive sector.
Solar paint in action: examples of efficiency
Mercedes-Benz tested the potential of solar paint in two real-world scenarios: Stuttgart, Germany, and Los Angeles, USA. In Stuttgart, where the sun is not as generous as in warmer regions, the technology was able to supply 62% of the energy needed to travel the 52 km per day that a Mercedes-Benz vehicle usually does in the region.
In Los Angeles, with more favorable solar incidence, a car with solar paint can cover 100% of its daily trips using only the energy captured by sunlight.
These results show how solar paint can make a significant difference, especially in regions with high solar radiation, reducing dependence on traditional energy sources and making vehicles more self-sufficient.
Sustainability and innovation go hand in hand
Sustainability is an essential pillar in the development of this technology. Mercedes-Benz emphasized that the solar paint contains no toxic materials and is completely recyclable, standing out as an environmentally friendly alternative to conventional solar modules. In addition, the energy efficiency of the coating contributes to reducing the carbon footprint of vehicles.
Another important point is the flexibility of the application. As the coating can be adapted to different shapes and angles, it offers almost unlimited design possibilities for cars, while maintaining the brand's characteristic visual appeal.
The future of solar powered cars
Although still in the feasibility testing phase, Mercedes-Benz's solar paint signals a promising future for the automotive sector. With it, not only can fossil fuel consumption be drastically reduced, but also the reliance on electrical grids for charging Batteries high-voltage. For consumers, this represents significant long-term savings and a more sustainable driving experience.
This technology could pave the way for applications in other sectors, such as public transport vehicles, trucks and even vessels, further expanding the positive impact of solar paint on the use of renewable energy.
Mercedes-Benz reaffirms its leadership in innovation
Mercedes-Benz has always been synonymous with innovation in automotive market, and solar paint is yet another example of how the brand continues to invest in pioneering solutions.
By integrating technologies such as solar energy, augmented reality and recycled materials into its designs, the company not only reinforces its commitment to sustainability, but also leads the way towards a cleaner, more efficient future.
As we await the next advances in this revolutionary technology, one thing is certain: Mercedes-Benz’s solar paint is a milestone that could transform the automotive industry and inspire other automakers to follow suit. After all, when the sun becomes fuel, the future looks much brighter.
It puts an end to criticism about the difficulty and sustainability of electric refueling. Very good
This is a concept in technology
The whole problem is if you scratch the paint, the power goes out.
