Mercedes-Benz EQXXAptera Sol, Lightyear One, Sono Motors Sion…There were many willing applicants among car manufacturers democratize the solar roof for electric cars.

At Fisker, we believe in it!

The technology, it would seem, is a “trick”, which, nevertheless, was to improve the overall characteristics of the car. Either by giving it a few precious kilometers of additional autonomy, or canceling the loss of autonomy associated with the use of equipmentnt and on-board electronic organs. But Lighter went bankrupt, Sono Motors abandoned the Sion projectAND Hyundai only offers this feature as an option on its IONIQ 5. As far as Mercedes-Benz is concerned, the EQXX was only a concept car, and this principle has not yet been implemented on a production model… Who is left?
Starting with small niche builders, the most convincing technology was developed by Fisker. This American manufacturer, previously known for its Karma electric sports car, is returning to motor racing as before with models that run exclusively on batteries. It is called a model that marks its update The Ocean is a large family SUV assembled in Graz, Austria, whose first deliveries to France have recently begun..

Really effective?

It presents its high-quality finish Extreme AND Solar Sky Roof which, according to the brand, would allow recover approximately 1,500 miles (2,400 km) per year in ideal sunny conditions. But in reality and according to experts, the voltage and amperage of such a system do not allow to significantly increase the autonomy. For example, we can’t expect a car to recover from a breakdown using only the power of the sun, enough electricity to be able to hit the road again…
However, this system has two advantages: first, it allows prevent the loss of autonomy associated with the use of multimedia, ventilation, lighting and electric seats Example. On the other hand, for almost the same reasons, having it on a glass roof allows you to achieve better filter the heat entering the cabin, and therefore also use less air conditioning. Despite its promising beginnings, the sunroof today seems to have become a kind of gadget aimed at niche customers.

Not quite a leap forward for the technological advancement of electric vehicles…
