Mercedes-Benz has revealed that it is researching a groundbreaking solar power technology that could be integrated into future vehicles. Rather than using conventional solar panels, the automaker is working on ultra-thin “solar modules” that would be embedded directly into the paint of the vehicle.
These modules are just 5 micrometers thick, far thinner than a human hair, and approximately the diameter of a red blood cell. This thin layer would allow for the generation of solar power while maintaining the vehicle’s aesthetic and aerodynamics.
The solar module layers are incredibly lightweight, weighing just 50 grams (0.11 lbs) per square meter. For example, covering a mid-size SUV with this technology, which has a surface area of approximately 118.4 square feet, would only add about 1.2 pounds to the vehicle’s weight. Mercedes-Benz claims that the materials used are sustainable, with no rare earths or silicon involved, and they are recyclable, though how to recycle such a fine layer remains a challenge for the future.
In terms of performance, the solar modules are reported to have an efficiency of 20%. Over the full surface area of an SUV, the system could generate enough energy for up to 7,456 miles of electric driving range annually — an impressive 20.4 miles per day.
This is far more than what solar roofs on existing vehicles like the Toyota Prius Plug-In Hybrid (which can add up to 3 miles per day) are capable of. However, Mercedes acknowledges that factors like shade, sun intensity, and geographical location will significantly influence the amount of energy generated.
While the technology holds promise, there are still caveats to consider. The estimate of 7,456 miles per year was based on conditions in Stuttgart, Germany, and assumes the vehicle’s surface is optimally positioned for solar energy capture, which might not always be the case in real-world conditions.
Additionally, Mercedes did not provide specific details on power output, only giving an estimate for driving range, which could vary based on the efficiency of the vehicle. Despite these uncertainties, the potential for solar-powered energy to supplement electric vehicle charging is an exciting development, particularly for vehicles venturing into remote areas where charging stations are sparse. However, the reality of a fully solar-powered mainstream vehicle is still far off, as previous attempts by other companies have shown.
