Islamabad, June 29, 2025: Mercedes-Benz has revealed a groundbreaking solar paint technology for electric vehicles (EVs), aiming to extend driving range by harnessing sunlight. This innovation could add up to 20,000 kilometers of range per year in optimal sun-rich environments like California.
Integrated Solar Paint Technology
At just 5 microns thick and weighing 50 grams per square meter, the paint embeds ultra-thin photovoltaic cells directly onto the vehicle’s body. A nano-coated top layer lets 94% of sunlight reach the cells, while allowing any custom car color finish.
Power Efficiency and Performance
With an efficiency of around 20%, similar to rooftop solar panels, the solar layer covers about 11 square meters of the car’s surface. It can generate enough electricity to support 12,000 km/year in Europe and up to 20,000 km/year in sunbelt regions.
Smart Energy Integration
The system includes a micro-converter that boosts the solar energy output to charge the EV’s high-voltage battery, even while parked. Mercedes also hints at vehicle-to-grid (V2G) functionality, allowing unused solar power to be fed back into home energy systems.
Eco-Friendly Manufacturing
Unlike traditional panels, the solar paint uses no silicon or rare earths. It’s applied at room temperature, saving energy during production and reducing the carbon footprint.
Challenges to Mass Adoption
Despite its promise, full-scale production poses hurdles. Vehicle shapes vary, and maintaining efficiency over time requires tough resistance to weather, dust, and wear. Mercedes plans more testing through 2025, with commercial rollout expected by 2040.
The Future of EV Charging
This technology could transform the EV industry in Pakistan and globally, reducing reliance on charging stations. While it won’t replace plug-in charging entirely, it could lower running costs and reduce range anxiety—especially in sunny regions.
