Various vehicles, including EVs, hybrids, and traditional gasoline-powered cars, have previously featured solar cells installed on their roofs. However, these cells are typically rigid, prone to breakage, and limited in flexibility.
Mercedes’ innovative solar paint boasts a thickness of only 5 micrometers and a weight of 50 grams per square meter. It can be applied to any material and surface, including wheels, curved fenders, and hood creases.
Although the solar paint can be customized in any color, darker shades are preferred due to their light-absorbing properties. Mercedes engineers have confirmed an efficiency rating of 20%, aligning with current solar cell standards for vehicles.
The energy generated by the solar paint can be stored in the vehicle’s high-voltage battery, providing a continuous power supply regardless of the vehicle’s operational status.
According to Mercedes’ analysis, an average Los Angeles driver covers 29 miles daily, while an EV equipped with the solar paint could potentially generate up to 34 miles of energy per day.
Mercedes has described the solar paint as a paste-like substance, but the application method remains undisclosed, ensuring a unique and precise integration process.
