The main advantages of being designed as a solar battery are:
1. The calculator consumes too little power, and almost all calculators do not have a backlight, and must be used in a light environment. The weak solar power panel is enough to support.
2 Use ordinary (replaceable ) Compared with battery calculators, solar calculators require only one investment, which is also a design advantage in the eyes of users. If ordinary batteries are used, only button batteries can be used with the thickness of the calculator. At this time, different users’ habits will lead to There is a huge difference in battery life (the calculator is not separated from the cashier with the left hand vs. the elementary school student who only cheats with the calculator at the end of the period).
This uncertainty in battery life leads to:
1. no one knows when the calculator will be It will run out of power (if the power is displayed, it will waste display space, and add more programs/hardware to detect the power).
2. Button batteries are not sold everywhere, and it is not very convenient to replace them. There are always a large pile of them at home It seems stupid, and improper recycling is not environmentally friendly. It can be seen that the design of using ordinary batteries is not helpful to the original intention of the calculator itself as a “convenient and reliable” tool. So add a little on the calculator The (very low cost) solar panels are cheaper and more convenient and more environmentally friendly than ordinary batteries.
