Please use it in the context of enough sunlight or light Do not disassemble, twist, bend Pass Do not use sharp objects cutting surface Keep dry! Do not water or in damp environments How to Use a Solar Power Calculator?: : Use most solar powered calculators like you would any other calculator; direct exposure to light typically doesn't matter Recharge a battery powered calculator by leaving it in a bright location but out of direct sunlight Recognize when you have a true solar calculator. The numbers will fade when the light is blocked and there will often be a noticeable lag between pushing a button and its appearance on a calculator. When using a true solar calculator operate it in a bright location but still out of direct sunlight Clean off the panels occasionally to keep them working well. Dust, dirt and oils from your fingers can cause a significant amount of refraction, and the solar energy is lost. Wipe them off with a paper towel or even the end of a shirt, the plastic covering over the panels will protect them Nearly every basic calculator has a set of solar panels built into it. Even so, these calculators usually come with a battery inside that actually powers the device. These panels help extend the life of the calculator by slowly recharging the original battery. The manufacturer's intention is to make the calculator last long enough that it gets replaced for a reason other than the battery, often being dropped and broken: How Does a Solar Powered Calculator Work at Night? : The process-Many readers may remember sitting in biology class and learning about photo-synthesis. Photo-synthesis is the process where plant-life takes in the rays of the sun and essentially converts that into food or energy. The solar powered calculator works much in the same way in that instead of plant cells, the calculator has the solar panels which consist of solar cells or photoelectric cells. These cells accept the sunlight and, acting as batteries, stores the sun's light and converts it into electricity. This, when you use the calculator, instead of alternate battery current, you are using energy converted from sunlight Night Ops- Fortunately, these cells can store an amazing amount of energy for their size. The drawback, like with a rechargeable battery, is that they must be recharged frequently. In this case the calculator needs to be in sunlight as often as possible in order to maintain a constant supply of electro-power : 1 x PP Case * 1 x Credit Card Solar Power Calculator
