Solar-powered calculators are great to lower your carbon footprint and save money. In this blog, you will discover the power of solar energy in powering calculators, understand how solar-powered calculators work, their power consumption, and solar generator can power a calculator. Besides that, we can explore different types of solar generators offered by BougeRV that can efficiently charge not just calculators but also other small appliances.

Now, let's learn about these eco-friendly, cost-effective solutions and take an important step toward sustainable living.

What Is The Solar-Powered Calculator?

A solar-powered calculator is a compact device that harnesses sunlight to operate. Equipped with mini solar panels in the back of the calculator screen, these calculators convert light directly into electricity for the calculator battery. This means even in indoor environments with sufficient ambient light, these calculators can work perfectly.

Basically, solar-powered calculators don't require traditional batteries to work and hence, they are eco-friendly. It’s also cost-effective as you save on battery replacement costs. Perfectly used in classrooms, offices, or at home, solar-powered calculators are typically designed for simple arithmetic operations. But, you can also find advanced models for scientific or financial calculations.

Solar-power calculators are just one example of how we practical eco-friendly in our daily lives. They help us reduce our carbon footprint and act as an educational tool, demonstrating the practical usage of solar energy. Using a solar-powered calculator, we take a small yet significant step toward sustainable living!

How Do Solar Powered Calculators Work?

Solar-powered calculators use solar power instead of electricity. The operating of a solar-powered calculator uses the photoelectric effect, which includes electron emission when the light strikes the solar cells.

When the calculator is exposed to sunlight, the light photons hit the solar panel, causing electrons in the solar cells to be knocked loose. These loose electrons generate an electric current that powers the calculator. The excess electricity generated by this process doesn't go to waste either.

It's stored in rechargeable batteries within the calculator. These batteries act as power stations, ensuring the calculator continues to work even when there's no available sunlight.

How Much Power Does A Solar-power Calculator Use?

A solar-powered calculator, as an energy-efficient gear, uses very minimal power. The power consumption depends on the calculator's wattage and the duration you use it. Here, we list different types of calculators' wattage and how much power they need as follows–whether it is a basic model, a scientific calculator, or a more complex graphing calculator:

  • On average, a solar-powered calculator is around 0.02-0.35 Wattage. This means it needs 0.1 to 1.75 Wh when the gear is used for 5 hours.
  • A scientific calculator, with its advanced functionalities, requires slightly more energy. The Wattage of Wattage of scientific calculator is 0.35W and typically consumes 1.25 Wh over 5 hours.
  • In contrast, a graphing calculator, known for its higher processing power, has Wattage up to 0.35W and uses 1.75 Wh in the same duration.

Can Solar Generators Charge A Calculator?

Yes, A solar generator can power various devices including a calculator. It comes with solar panels that convert sunlight into electricity and power stations that store the electricity for later use.

Interestingly, it's worth noting that a solar generator creates far more power than what a typical calculator requires. As mentioned earlier, calculators have very low energy needs. On the other hand, a solar generator, even a small portable one, produces power in the range of tens to hundreds of watts. So you potentially power 100+ or 1000+ calculators with a single solar generator at the same time. That being said a solar generator provides ample power for low-energy devices.

“This box is amazing. I used it to DJ at my niece's bday party recently. It ran off one solar panel alone, all night, all my amps and powered speakers. It still had the same amount of juice after running for 3 hours after dark, as it did before I plugged in the panels. Also, we use it every weekend when we camp, to power the camp fridge. I've also run an induction cooktop off it and cooked with it. Why are you still reading? Go buy this thing!”----Jacob

“Ordered this power station late last year. It has worked flawlessly and I would recommend it. It is great for small loads (under 700watts), is lightweight, and works great for off-grid power during camping.”----Ken

Solar Generator For Calculator vs. Solar Powered Calculator

Both solar-powered calculators and solar generators for calculators save energy and help reduce your carbon footprint. However, using a solar generator for calculators is an even better solution to some extent.

A solar generator can charge a calculator for a long time. And it can run other study devices such as phones, laptops, lamps, iPad, etc. as well as small appliances. Given that you go camping a lot or live in a rainy area, it’s better to have a solar generator for the calculator. However, to choose between, let’s delve into the pros and cons of solar-generator for calculators vs. solar-powered calculators.

Solar Generator For Calculators

Solar generators combine solar panels and portable power stations to charge devices. The best thing about the solar power generator is that it allows you to power other study and work devices like laptops, phones, etc.

BougeRV is one of the top solar brands that provide efficient solar panels and power stations.

Higher initial investment. Solar generators of higher capacity are expensive compared to solar-powered calculators.

Solar Powered Calculator

Solar power calculators are highly efficient and durable. They harness sunlight to perform various functions, making them environmentally friendly. These include standard calculators for basic mathematics, financial calculators for computing interest and mortgage rates, scientific calculators popular among students, printing calculators that can perform basic functions and certain financial formulas, and graphing calculators used for creating charts and graphics.


  • Portable and convenient
  • Affordable.


  • Take a long time to fully charge.
  • May not work efficiently during cloudy days.
  • May not work or study at night. Solar-powered calculators may not work without a rechargeable battery at night or indoors without sunlight.

What Size Of Solar Generator Should I Buy For A Calculator?

Supposed you eventually decide to own a solar generator to charge a calculator, what size of solar generator do you need?

As we said, the average solar calculator consumes 0.02W-0.25W. A small solar generator is completely enough to power a calculator. For example, using a compact BougeRV 286Wh Power Station With 130W Solar Panel Kits, the working time of the solar calculator at 0.25W is

286Wh*85%/0.25W=972.4H (constant energy consumption rate of 85% when the device is in charge)

However, in case you use a solar generator powering a calculator and arrays of appliances or devices simultaneously, a solar generator with a higher capacity will be a better choice. By calculating the total power consumption of your calculator and devices, you can easily clarify how big a solar generator you need! Here, BougeRV created a useful solar calculator online that helps!
