The power of sunlight is about 500W per square meter and the total of fluorescent lamps is only tens of watts. The radiant power is small and the power per unit area is poor. Even if it can be charged, you have to wait until the year of the monkey to be full. It is known that the common solar calculator does not have a charging function, because it uses 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 the battery power is not used at this time. General solar panels, light from the sun, incandescent lamps, halogen lamps, fluorescent lamps and other light sources can generate electricity. Because the power of the solar computer is extremely small, the current required is also extremely small. Therefore, as long as there is very weak light, the solar-powered computer can work.
It’s not all light. Normal photocells only respond to visible light. Infrared and ultraviolet light are not. not enough. Common solar calculators do not have a charging function, because they use ordinary silver oxide button batteries inside, which are not rechargeable batteries.
