 The motors used in solar cars typically generate about 2 or 3 horsepower, yet experimental light solar cars may attain the same speed as a typical family car ().To keep the car running smoothly, the driver must monitor multiple gauges to spot possible problems.Cars without gauges almost always feature wireless telemetry, which allows the driver's team to monitor the car's energy consumption, solar energy capture and other parameters and thereby freeing the driver to concentrate on driving.
