7 handy solar gadgets that run on solar energy

7 handy solar gadgets that run on solar energy

Solar gadgets are environmentally friendly and also very practical: You don’t have to constantly change batteries and you can charge your electrical devices independently of sockets – and it’s even free of charge. We have put together a small selection of seven useful solar gadgets for you.

Garmin Fenix ​​7 Solar: Smartwatch with solar boost

Smartwatches are extremely practical everyday helpers, but due to their small batteries, they have to be plugged in relatively often – especially when tracking activities.

The smart watch Garmin Fenix ​​7 Solar therefore uses a built-in solar panel that increases battery life. If the wearer is outdoors for 3 hours a day with a brightness of 50,000 lux, the battery life is extended: from 18 to 22 days if only the basic functions are used, and from 57 to 73 hours if the GPS tracker is permanently switched on . On a bright sunny day it can get as bright as 100,000 lux, so it doesn’t need that much light.

In addition to the additional battery life, the Garmin Fenix ​​7 Solar also offers all the important functions that other smartwatches offer: smartphone notifications, measurement of various health data, activity tracking, contactless payment and much more.

Cheaper alternative

If the Garmin Fenix ​​7 Solar is interesting but a bit too expensive for you, then the Garmin Instinct Solar is a good alternative. Here you can find our test of the solar-powered fitness tracker.

the Eufy SoloCam S40 relies on the power of the sun to secure your home. The surveillance camera is equipped with an efficient solar panel that supplies it with electricity. A few hours of sunlight are enough for the security camera to be operational. And if the weather doesn’t play along, the integrated battery supplies the cam with energy.

The surveillance camera records all activities around your home in sharp 2K resolution. The artificial intelligence of the cam recognizes when people walk into the field of view and notifies you. On the other hand, passing animals or falling leaves do not trigger an alarm. The integrated headlight shines with a bright 600 lumens. The Eufy SoloCam S40 can be integrated into smart home systems and is compatible with the Google Assistant or Amazon Alexa.

The basic principle of solar power is simple: the sun shines on solar cells and these then generate electricity. But how does the physics behind photovoltaics actually work and what can the electricity generated be used for? The step-by-step instructions for the deal with these questions Cosmos Solar Bots.

A solar gear serves as a drive for the versatile solar bots. As far as the shape is concerned, you can really let off steam – eight different robots can be built with the set: beetle, racing car, dinosaur and five other exciting figures. Children between the ages of eight and twelve learn about technology and physics in a playful way.

A power bank always helps us when our smartphones run out of power and there is no socket in sight. But what if we are on the road for so long that the power bank is also completely empty at some point?

In such cases, it is practical if the power bank is recharged using solar energy – like the Xlayer Power Bank Plus Solar. The power bank has a capacity of 15,000 mAh, which means that it can also fully charge smartphones with larger batteries at least twice.

If that’s still not enough, it’s worth laying the power bank in the sun from time to time or attaching it to your backpack with a carabiner on trips, for example. So it slowly but steadily recharges itself. Thanks to the integrated LED, you can also use the power bank as a flashlight in the dark.

Facts about photovoltaics in Germany

In a recent study (August 2021) that Fraunhofer Institute for Solar Energy Systems ISE compiled some interesting facts about photovoltaics in Germany. Did you know that …

  • In 2020, 9.2 percent of gross electricity consumption in Germany was covered by photovoltaics (PV)? These are 50.6 TWh (terawatt hours)
  • PV power over on sunny days two-thirds can cover our current electricity consumption temporarily?
  • At the end of 2020, 2 million PV modules were installed in Germany, with a total nominal output of 54GW [Gigawatt] to have?

If you regularly use a wireless keyboard, you won’t be able to avoid an occasional battery change or battery charging. With the Logitech K750, however, replacing the battery is a thing of the past, because the chic wireless keyboard is completely powered by solar energy. Two solar panels above the keys ensure that the keyboard is supplied with enough power.

And this does not even necessarily require sunlight, because other light sources are sufficient to generate electricity via photovoltaics. In a well-lit office or study, the keyboard’s battery is already charged via normal lighting. When fully charged, the battery lasts a good three months, even in dark rooms.

Thanks to the flat keys, the Logitech K750 also offers a comfortable typing experience and can be used with almost any laptop, notebook or desktop PC via the USB 2.0 receiver.

One of the major uses of solar energy is the generation of light. That’s no wonder, because after all, LEDs get by with very little electricity and can be made to glow for a relatively long time with tiny solar panels. And hobby gardeners have been using this for many years to stylishly illuminate their gardens.

Solar lights for the garden come in a wide variety of sizes and shapes: there are spheres, cubes, plug-in lights for flower beds, animals with glowing eyes, illuminated flower pots, and so on. But solar lights are not only decorative.

In combination with motion detectors, they ensure that paths or front doors can be illuminated at night. The sun supplies the power for the LEDs during the day – completely free of charge.
