Yes. A solar calculator is a calculator that can be used under light or in the sun without batteries. The solar panel can still be used if there is not much water in it. After the water enters, you can wait for the water vapor inside to dry to see if it can still be used. If it is still unusable after the water vapor has dried, the circuit board should be replaced.
Can solar calculators be charged under fluorescent lights?
Solar calculators can be charged when placed in the sun, otherwise they would not be called solar energy. 1: Determine whether the internal battery is a rechargeable battery or a regular battery 2: Whether the battery is charged by solar energy and the battery is used to power the calculator, or whether the battery and solar energy can power separately the calculator, and Solar energy is usefulized for emergency purposes. 3: If so, the silicon photovoltaic cell should only be placed under ordinary light. It is only used as an auxiliary power supply for the battery. There are also single silicon photovoltaic cells that can power the computer. normal use. Without this type of battery, it cannot be used if the regular battery is discharged.
Common solar calculators do not have a charging function because they use ordinary silver oxide button batteries inside, which are not rechargeable batteries. It can only use solar panels to power the calculator circuit when there is strong light, and does not use battery power at the moment. General solar panels, sunlight, incandescent lamps, tungsten halogen lamps, fluorescent lamps and other light sources can ggenerate electrical energy.
