Solar Powered Calculator: Can Solar Generator Power A Calculator

With the demand for sustainable options growing, there is a boom in solar-powered devices. Solar-powered calculators are fascinating devices that utilize the sun’s energy to function. Most solar calculators have a small solar panel on top of it that collects energy. An average calculator consumes around 0.02 - 0.35 watts of solar power.

You can charge it using Jackery Solar Generators that are portable, safe, and quiet. From low-power-consuming to high-power-consuming appliances, you can charge anything with the robust solar generators from Jackery. In this guide, we will reveal what a solar-powered calculator is, how it differs from solar generators, and much more.

What Is a Solar-Powered Calculator?

A calculator solar-powered using the sun’s energy is gaining popularity, as it works solely using renewable and clean energy. They are a reliable choice for classrooms where students require these tiny gadgets to perform various mathematical calculations.

A solar panel is attached behind the calculator screen to convert sunlight into electricity and power the calculator’s battery.

Replacing traditional gadgets with solar-powered calculators will not only help alleviate the electricity bills but will also promote sustainable living.

How Does A Solar Powered Calculator Work?

Solar calculators are much like traditional calculators, but they use solar energy instead of electricity. The working of a solar-powered calculator focuses on the photoelectric effect, which includes electron emission once the light strikes the solar cells.

The excess energy generated is usually stored in rechargeable batteries. These power stations ensure continuous electricity supply to the calculators when sunlight is unavailable.

How Much Energy Does A Solar Powered Calculator Need?

The solar-powered calculator's energy consumption depends on the device’s wattage and the length of time you use it. This is because watts measure the power rate at which the work is done, while voltage is the pressure at which electricity flows from the source to charge the calculator.

You can calculate the watts by multiplying amperes with volts. Usually, the amps and volts used by the calculator are available on the backside of the device.

Solar Powered Calculator FAQs

What size of solar generator do I need to power a calculator?

Calculating the size of a solar generator is simple if you understand how many watts the calculator consumes. As we have discussed, a solar calculator consumes around 0.02W to 0.25W. Therefore, a small solar generator would be sufficient to charge the calculator for long hours.

Here we calculate how long a Jackery Solar Generator 240 can power a 0.25W calculator.

Working Time = Capacity in Wh * 0.85 / operating wattage of the device.

Working Time = 240 * 0.85 / 0.25 = 816H.

Jackery Solar Generator 240, with a battery capacity of 240Wh, lets you charge calculators, laptops, LED lights, fans, and other small appliances.

How to choose the best solar-powered calculator?

Below we include a few important things to consider while choosing the best solar-powered calculator.

  • Solar Panel Size:Ensure that the solar panel size is longer, so it can generate more power.
  • Type:Always ensure the solar calculators feature replaceable batteries if you plan to use them for the long run.
  • Price: The cost may vary depending on the features and type of solar calculators. Estimate the amount you are willing to spend on the calculator before you start shopping.
  • Calculator’s Size:Most solar calculators are small and portable, while larger ones are difficult to carry. Depending on your power needs, you can choose the right size calculator.

How long does it take to charge a solar calculator?

Generally, a calculator requires 20 hours of direct sunlight to fully charge.

Is a solar-powered calculator worth it?

Though solar-powered calculators are eco-friendly, they are not as efficient and reliable as solar generators. Having a solar generator means you can charge most devices using solar energy.

You can consider investing in Jackery Solar Generators that are portable, safe, and reliable charging solutions. It can help you power most study and work devices, ensuring you never run out of power.
