The Lightyear One is expected to reach a WLTP range of 725 kilometres when it is launched in 2021 \u2013 of course, the vehicle is not yet homologated at this point. According to the developers, the solar roof should provide enough energy to cover an average of 70-90 per cent of the annual mileage. However, Lightyear is assuming short car journeys, which average about 40 kilometres per day. On sunny days, the solar cells in the Lightyear One are expected to generate electricity for up to 33 kilometres \u2013 so under optimal conditions, the calculation works out. On cloudy days, in winter or simply when the car is parked in a garage, the solar power share will decrease considerably.<\/p>\n
Electric buses or electric trucks with their larger batteries can use considerably more solar cells. However, their daily mileage is usually much higher. Research is also being conducted in Germany on solar modules in electric commercial vehicles. In the ‘Lade PV’ charging project<\/a>, four industrial companies and two Fraunhofer Institutes want to demonstrate the marketability of photovoltaic applications in freight transport. “We not only want to develop the technology but also show that trucks can cover over five per cent of their propulsion energy with solar energy,” says project leader Christoph Kutter. “4,000 to 6,000 kilometres additional range per year is mathematically possible.”<\/p>\n“By stepping up our collaboration with Lightyear we are creating an entirely new market for \u2018lossless\u2019 high power back-contact technology \u2013 with the potential to change the face of clean mobility and make a big impact on climate change,” says Pascal de Sain, Vice President of DSM Advanced Solar. Martijn Lammers, Lightyear’s strategy chief and co-founder, adds: “By scaling up the accessibility of our solar technology through our partnership with DSM, we can accelerate the mass adoption of electric vehicles by making them sun-powered.”<\/p>\n
Koninklijke DSM is a chemical company based in Heerlen. Originally founded as a mining company (DSM stands for Dutch State Mines), the company produces industrial chemicals, pharmaceuticals and food supplements, among other things, and has also been working in the field of sustainable living for several years.<\/p>\n
