DHL Express, a provider of international express shipping services, is installing solar panel units on trucks in its U.S. pickup and delivery fleet. The goal of this solar installation is to reduce fuel consumption in markets throughout the country, according to a company release.

Equipping 67 of DHL Express’ medium- and heavy-duty trucks with Trailar solar technology is expected to reduce CO2 emissions by 1,000 kg per year for each vehicle, according to DHL, while lowering fuel and maintenance costs.

The solar system generates electricity from sunlight, and will be used to charge the battery and to power liftgates and other ancillary equipment. DHL shared that this reduces the load on the alternator and, as a result, fuel consumption.

“We’re aiming to improve the lives of people where they live and work, using cleaner pickup and delivery solutions – such as electric vehicles and cargo cycles, and now augmenting our truck fleet with this innovative solar solution,” said DHL Express U.S. CEO Greg Hewitt. “This is another strategic step in our drive forward to decarbonization, and over time reducing all logistics related emissions to net zero by 2050.”

An integrated telematics system provides detailed information on the efficiency of the entire system through web-based reporting, including battery health, charging of ancillary equipment, overall fuel, and C02 savings and more. 

With continuous battery management via the Trailar Smart Charge Controller, solar energy is used to maintain battery levels at the most optimum level, even when the vehicle is off. This constant care of the battery and reduction in alternator wear has a direct impact in reducing overall vehicle maintenance costs, according to DHL.
