Every time you are asked if you are willing to use solar energy as a source of electricity, the first thing that goes through your head is probably the large photovoltaic solar panels. But in reality, the use of solar energy has already been present in our daily lives for many years. The best example is the solar calculator, a small device that appeared two decades ago, and since then, it has been almost essential in any office or home.
If solar energy is infinite and accessible to everyone, why do we continue to use batteries and conventional electricity? Many people will say that technological progress is not yet enough for this clean energy to reach all pockets. But it is also because we are not willing to change our economic model or our way of life.
In the 21st century, the buy, throw and buy way of life has become a serious problem in society and our linear economy model carries worrying consequences. We are so used to having running water and electricity in the home that we have rarely asked ourselves where it comes from or its environmental footprint. In recent years, the rise in the price of oil and electricity, the increase in the level of pollution, and the serious consequences of global warming have made us think more and more about the sustainability of the current economic model.
We started buying electric cars, we started saving electricity, we started saying no to plastics, we started consuming more local products, we started asking what the circular economy is. For this reason, we have dedicated this article to compiling a series of solar devices that can be tremendously efficient in their domestic functions. They not only help us save electricity consumption but are more respectful of the environment.
It is one of the most present solar devices in our day and day. Solar calculators work with small solar panels and sensors. Some are dual-powered with backup batteries.
These devices are essential in any home. Its solar panel can absorb all kinds of natural and artificial light.
Outdoor Solar Lamp
You can find different models both in the form of a spotlight, lantern, glass jar, pendant lamp, table lamp, and in the shape of a brick. They are a good option to replace any type of electric outdoor lighting.
The vast majority of solar chargers are designed for emergency situations or outdoor activities. However, they are an environmentally friendly alternative to conventional chargers. They are ideal for small electrical devices such as mobile, tablets, or laptops.
Solar radios usually have several built-in functions. They have lights and an SOS alarm and serve as a charger. In some cases, it has a crank lever with which the power can be generated manually.
Instead of a boiler or electric heater, a solar thermal collector and a water storage tank are installed outside the house or building. Its use is very common in developing countries.
Pool Water Heater
It is a system designed to heat water using only solar energy. The result can be as good as an electric pump by increasing or maintaining the water temperature. The models are very varied, adapting to the needs of the user.
As children, we have all played with the magnifying glass and the sun’s rays at some time. Well, there are solar cookers that are based on the concentration of radiation, achieving a focus for cooking food. Its use is widespread throughout the world, and there are projects that promote its use, especially in emerging countries.
They work without electrical connections and are ideal for the garden. It is a very sustainable way to have outdoor showers near the pool or the beach.
Similar to solar street lights, there are surveillance cameras that work with solar energy through the incorporation of a solar panel and an internal battery. It works independently of electric light.
In addition to these solar devices, you can also find a wide variety of inventions that are powered by solar energy, such as laptops, plugs, headphones, sunglasses, and bags. We must also add the advances of solar cars and drones, among others.
And you, the next time you go to buy an electrical appliance for the home, are you going to consider these more ecological options?
