"Tokyo, Japan, July 4, 2019―NEDO, Sharp Corporation (Sharp), and Toyota Motor Corporation (Toyota) announce today a plan to commence public road trials from late July 2019. The trials aim to assess the effectiveness of improvements in cruising range and fuel efficiency of electrified vehicles equipped with high-efficiency solar batteries." "......To facilitate the execution of this trial, Sharp modularized its world-class, high-efficiency solar battery cells*1(conversion efficiency of 34 percent-plus*2), previously developed for a NEDO-led project*3, to create an onboard solar battery panel. Toyota installed this panel on the roof, hood, rear hatch door, and other parts of its "Prius PHV" and produced a demo car for public road trials. By enhancing the solar battery panel's efficiency and expanding its onboard area, Toyota was able to achieve a rated power generation output of around 860 W*4, which is approximately 4.8-times higher in comparison with the commercial model Prius PHV (equipped with a solar charging system). In addition to substantially boosting its power generation output, the demo car employs a system that charges the driving battery while the vehicle is parked and also while it's being driven, a development that is expected to lead to considerable improvements in electric-powered cruising range and fuel efficiency. BEV-mode cruising range equivalent to 44.5 km [27.65 mi] * Maximum amount of charge generated by the solar charging system while the vehicle is parked or being driven, converted into travelling distance according to the JC08 Japan test cycle. Calculated based on the Japan Photovoltaic Energy Association Labeling Guidelines (FY2016), taking into account the various losses incurred in onboard systems. Solar radiation amount calculated based on the daily data of the average year between 1990 and 2009 in the Nagoya district (source: NEDO). https://global.toyota/en/newsroom/corporate/28787347.html?adid=ag478_mail&padid=ag478_mail /this sounds a little too good to be true. Anyone with solar knowledge want to give an opinion?
