There is a level indicator on the display screen that shows the power level generated by the solar panel. Under good conditions, there is sufficient power generated to charge the batteries and power the radio. The built in rechargeable battery pack is charged whenever the solar panel receives direct sunlight. Once fully charged, the low power consumption of solarDAB allows the batteries to power the radio for up to 27 hours without the need to recharge them. The radio can then be used away from sunlight or mains electricity until recharging becomes necessary.
