Case Clean Motion

Clean Motion has developed the ultra-light electric vehicle Zbee with the goal to create a vehicle using little resources, both at production and usage, without compromising safety or design. Solar panels would give the possibility to use solar energy to recharge the vehicle's battery, which would increase the possible driving distance before need of conventional battery charge.
Midsummer solar panels are flexible both by being bendable and possible to manufacture in different size and voltage configurations. Also, the CIGS cells on thin stainless steel substrates together with the plastic material layers give resistant light-weight modules.

Clean Motion and Midsummer have worked together to provide ZBee with solar cells that charge the battery. Standard 6" solar cells in a solar panel shaped like a "W" allowed mounting onto the double-curved roof. The tests conducted in Sweden showed that solar energy increased the mileage with 5 km/day, which is 10% increase. On the southern latitudes and with optimized PV area and electronics, mileage would increase further and some users would thus not even need conventional battery charging.

Development will continue, to improve integration and performance, since the initial Zbee project demonstrates that solar cells have the potential to replace conventional battery charging. As well as that Midsummer solar panels are well suitable to be customized for different applications.
