Empowering Trucks with Solar Energy

Page last modified
April 11 2024

SolarOnTop is a cutting-edge onboard solar technology designed specifically for trailers. By harnessing solar energy, you empower your trucks and achieve a significant reduction in fuel consumption, from 1,000 to 3,000+ liters annually, while reducing carbon emissions by 3 to 9 tonnes of CO₂ per year. SolarOnTop is a game-changer in the transportation industry.

Equipped with flexible solar panels, a lithium battery, and energy management system, SolarOnTop ensures an uninterrupted power supply even during nighttime or cloudy weather conditions. SolarOnTop provides clean electricity to the truck while driving, reducing the load on the diesel engine. It also charges electrical appliances (liftgates, electric pallet jacks, forklifts, tail lifts, movable floors...) in trailers. When parked, it powers cabin electronics like HVAC, lights, and entertainment systems.

Embrace sustainability and say goodbye to soaring fuel and maintenance costs while maximizing your return on investment by adopting SolarOnTop.
