Charge your car on sunshine, not on the grid

Why Sun System?

Charging at home should be simple, but most installations draw from the grid at the worst possible moment. We design systems that charge more intelligently, not just faster.

Homeowner going through solar savings and energy cost estimates

What you pay

Public charging is expensive, and charging at home on grid electricity at peak times is not much better. Hardly anyone realises how much the time of day affects the cost.

Electric vehicle charging powered by renewable solar energy

When you charge

Charging in the evening falls in peak hours. That is when grid energy costs most, and exactly when most people plug the car in after work.

What you control

Without solar integration you pay whatever your supplier charges at the moment you plug in. No optimisation and no visibility.

Cheap charging is not a matter of luck

Charging an electric car should not double your bill. We design integrated charging systems that use solar generation first and the grid as a last resort: your car runs on sunshine, not on nasty surprises.

Dependence on the grid

Charging from the grid alone means your "fuel" is still priced by your supplier.

Charging with no logic

A basic charger draws power without knowing what it costs.

Invisible extra cost

Charging at peak times can add €60–90 a month without you seeing it.

Equipment that does not talk

Most chargers do not communicate with the panels or the battery.
