EPEQ Solar Assist from Vanair integrates a factory-installed solar charging system into work truck equipment to offset parasitic electrical loads. The system arrives pre-wired and mounted to equipment before upfit, eliminating additional wiring, labor, and the need for roof-mounted panels. It continuously supplies power to telematics, sensors, security systems, and onboard electronics, helping maintain battery state of charge when the vehicle is off. The solar array uses a patent-pending mounting design and MPPT charging to maximize energy harvest—up to 45% more efficient than PWM systems—while performing in low-light and partial shading conditions. Built to withstand harsh environments, it supports longer battery life, reduces dead batteries and roadside service calls, and helps limit wear on alternators and starters.
