Toyota using Kyocera solar panels
A
The solar panel moonroof option costs $2,076 and has an efficiency of 16.5% but since it does not charge the battery directly and sole purpose of the solar electric system on the Prius is to power the air ventilation system the return on investment on the solar panel moonroof is quite non-existent. I suppose this option is more for show than practicality, wouldn’t you agree? How could have Toyota leveraged the power generated by solar panel moonroof more effectively?
