There are two types, one that can be installed with batteries and the other that relies solely on light. If your solar calculator cannot be installed with batteries, it can only rely on light to provide power. It cannot be used without light. .
Of course there are differences in quality. For example, if the quality is better, just a little light is enough~
What should I do if the reflection of the solar computer slows down
Originally, we called it a dual-powered calculator, but I discovered that if my calculator's solar panel was backlit, the numbers would not display clearly, if at all. I simply removed a solar panel. and I installed it on another calculator without exposing it to the sun, just the sun to the light.
Even if it is a brand new 5# dry cell, if the solar cell is not working, you will not see the chifres on the screen if you connect the positive and negative poles of solar energy. the new cell dries in parallel, nothing will happen. But if there is no dry cell, there will also be a solar cell.
The solution to the slow response of the solar computer is as follows:
1. Replace the battery. If the battery charge is too low, the solar calculator may react slowly. You can fix this problem by replacing the battery with a brand new one.
2. Clean the calculator. Dirt such as dust and grease can build up on the calculator's keyboard and screen, which can affect how quickly it responds. You can use a soft cloth to gently wipe the keyboard and screen to ensure they stay clean.
3. Replace the solar panel. If your solar calculator does not operate properly for an extended period of time, the solar panel may bebe defective. You may consider replacing the solar panels so that the calculator can work properly.
4. Reset the calculator. Sometimes a solar calculator may malfunction for some reason, in which case you need to reset it. On most calculators you can find a clear or reset button which, when pressed, can return the calculator to normal.
