Toyota’s new Prius has come up with an updated model by using Kyocera Corp's solar panels which are mounted on the roof. The cells used are polycrystalline Si solar cells which is a cheaper option compared to other solar cells. In total, the solar panel is composed of 36 cells arranged in six rows and six columns. Each cell is half the size of the standard 15 x 15cm cell. With a cell conversion efficiency of 16.5%, the maximum output of the entire panel reaches fifty-odd watts. The portions where three bus bars are believed to exist were covered with a black component. Electricity generated by the solar cells directly drives the ventilation fan.

The "solar panel moonroof" option, which integrates a solar panel and a sunroof, is priced at $2,076.
