Solar Panel Charging System

Global First1Column

Converting sunlight into driving energy.

The large solar panel mounted on the vehicle roof generates power for EV-mode cruising. The vehicle’s battery can be charged with sunlight just by parking it outdoors. This power is used for EV-mode cruising, air conditioner operation, and to supply AC100 V external power. While driving, electrical power generated from sunlight is stored in the auxiliary battery (12 V). This helps reduce the load placed on the battery and improves EV-mode cruising range and fuel efficiency. In a single day this system generates, on average, enough power to drive 2.9 km2, and under optimal conditions as much as 6.1 km.

  1. As of January 2017. According to Toyota Motor Corporation.
  2. Calculated taking into consideration amounts of loss of each vehicle system, in accordance with the “2015 Labelling Guidelines” issued by the Japan Photovoltaic Energy Association. Daily sunlight data for the Nagoya area for average years between 1990 to 2009 was used (source: NEDO).
