At the end of July 2019 in Japan will start tests of an electric vehicle Toyota, equipped with highly efficient solar panels Sharp. The company already has a Prius PHV with optional panels on the roof, but thus derived energy is only enough to charge auxiliary devices. The novelty solar cell 4.8 times more powerful and provide an increase to the reserve at the level of 56.3 km.
As the press service of Toyota, the prototype for road testing equipped set of photovoltaic panels, which are placed not only on the roof, but also on the hood and tailgate. As a result the power was increased to 860 watts, and the efficiency exceeded 34 percent. For comparison, the serial PHV Prius with an optional solar panel, the figures are 180 watts and 22.5 percent, respectively, and at the time of the motion energy is not accumulated, in contrast to the experimental instance. If you compare added to the reserve, then the day in the Parking lot of a solar panel prototype will provide 44,5 km, and the commercial version is 6.1 km.
For developing highly efficient modules, answered Sharp. The company assured that the energy collected by these panels will be enough to increase the reserve of electric vehicles on the 56.3 kilometer. These are just preliminary calculations, and real data of Toyota and Fujitsu intend to obtain during testing of the prototype on the roads.
At the end of June were presented One Lightyear electric car on solar batteries which can be charged independently. This liftback is equipped with four electric motors and a set of batteries, allowing to drive without charging about 725 miles on the WLTP cycle. The developers claim that in clear weather the solar panel allows the car to 20 000 “free” kilometers per year.
