THE POWER OF THE SUN

Solarly.ch electric motor is powered by batteries which are loaded continuously by solar the panels installed on the roof of the bridge.

The electricity produced by the photovoltaic cells goes through batteries before being directed to a chopper which supplies the engine through a regulator that allows to adjust the intensity and the polarity of the current delivered to the engine for to modulate the speed and direction of rotation.

E-POWER AND SPEED CONSUMPTION

By good weather in summer and at a speed of approx. 6-7 km/h the electricity provided by the solar panels is quite sufficient for the motor power supply. At this point the boat imoves only by solar energy and has an autonomy proportional to the quantity of sunlight + the reserve of power loaded in the batteries.

The capacity of the batteries is largely sized to ensure a comfortable autonomy in navigation.

At a max. speed of 10.7 km/h, autonomy is reduced to approx. 3 h / 32 km.
At 9 km/h autonomy is nearly 6h00 / 54 Km.
A 7 km/h autonomy passes to nearly 12h / 84 Km.

Even by cloudy weather, depending on the amount of light received, the boat can move at 3-4 Km/h without using the power of the batteries.
The maximum speed  (10.8 km/h depends on the shape of the hull, the more the hull is tapered, the better the performance.

By intense sunlight and at a speed of approx. 5.5 - 6 km/h autonomy is infinite, as long as the sun shines high in the sky.

For example it should be posible to go from Vevey to Geneva (65 Km according to the shortest line) in about 10h 30.
