HOW IT WORKS
How vehicle solar works
Solar panels on the vehicle roof generate electricity and feed it directly to the battery via the charge controller. This reduces alternator load, so the engine burns less fuel to power onboard systems.
Below you can see how the system works, how it is installed, and recommended solutions for trucks, buses and trailers.
FUEL SAVINGS
Where do fuel savings from vehicle-mounted solar come from?
Not from changing routes.
Not from changing driver behaviour.
Not from replacing the engine.
In a conventional vehicle, the alternator charges the battery and is driven by the engine. This means the engine burns diesel to produce electricity for the vehicle’s electrical systems.
Solar changes this dynamic. During daylight hours, the panels generate electricity and store it in the battery. This stored energy powers onboard systems as required, reducing how often the alternator needs to draw power from the engine.
In a conventional vehicle, the alternator charges the battery.
The alternator is driven by the engine.
The engine burns diesel to produce that power.
Solar changes that dynamic.
Solar does not replace the alternator — it takes over much of the battery charging work during daylight hours.
The battery stays at a healthier state of charge
The alternator runs less often and at lower output.
The engine spends less time burning fuel to generate onboard electricity.
Less alternator load = lower fuel consumption and reduced mechanical strain.
