Increase APU Efficiency with Solar Panels

Decrease APU Runtime by up to 30%

Solar panels allow the APU to have healthier batteries, minimizing the engine runtime necessary and ultimately driving down fuel and maintenance expense for an outstanding ROI. ThermoLite® solar panels help lower operational costs by reducing diesel APU run time by 20-30%, extending battery life to five+ years, and helping match APU and tractor preventive maintenance.

Support for tractors and electric APUs

Reduce costly downtime and support sustainability plans with  a ThermoLite® solar charging system.  Solar power offers a host of benefits for tractors with an APU or utilizing electric APUs.  Solar improves the overall health of tractor and APU batteries, increasing electric component runtime and reducing the reliance on tractor charging and idling, saving fuel and maintenance expense.
