Diesel Locomotives and Trucks

There can be a significant Return on Investment (ROI) by installing solar power. 


Diesel locomotives

For example, installing solar on a diesel locomotive means that staff no longer have to regularly run the diesel engine, or attach a mains battery charger, to recharge flat batteries if the locomotive has not used for several weeks.  

Solar charging reduces diesel consumption, extended the battery life, and improved productivity.

Trucks and trailers

Solar power on trailers and sleeper cabs provide an off-grid, independent power source that can top-up the battery bank to ensure ample power is available to power lights and monitoring equipment. 

Telematics can drain a starter battery.  Solar power can ensure optimal charge can be maintained during periods of trailer inactivity so batteries remain topped-up. A few watts up to multiple kW systems are possible. 

Longer battery and alternator life provide further return on investment as well as eliminating service calls for jump-starting.  Solar panels can help keep batteries charged for truck and trailer refrigeration, liftgates, pallet jack chargers, safety lights and trailer tracking and telematics, even when the trailer’s untethered. 

Solar is particularly good for leasing companies and fleets that drop trailers periods of time.

Adding an inverter can provide a safe supply of AC power.  Solar panels also provide driver comfort without idling, allowing noiseless sleep and allows the refrigerator to remain on in the sleeper when the driver’s off the truck for an extended period.
