How do solar lights work

If you didn’t know by now, solar energy is the energy of solar radiation that we notice in the form of heat and light. The sun is by far the largest source of renewable energy on Earth, and renewable energy is considered to be energy derived from direct or indirect solar radiation because it does not disturb the natural balance between matter and energy. By using photosynthesis, nature easily stores solar energy in the form of plant mass.

History of solar energy use

Ancient civilizations used solar energy much more in their homes than we do in an era where technology is continually advancing. Ancient Egyptians, Chinese, Greeks, Romans have been using solar energy since ancient times by orienting their homes south, giving them more natural sunlight and warmth in their homes in the winter. It is no coincidence that Roman baths necessarily had large windows just on the south side. Ancient civilizations clearly knew factors such as solar orientation, thermal mass, and ventilation.

What are solar lights

Solar lamps are specific in that they do not consume electricity, but have a battery that is recharged during the day with the help of sunlight. This way, you will not incur additional costs, especially for paying electricity. Thanks to the power of the sun, your backyard will be beautifully lit. Because solar lamps do not consume electricity, one of the most significant advantages of this lighting method is that no electrical wiring is required.

How to use solar lights

The instruction manual you will get by purchasing solar lamps will explain in detail how to best accumulate energy during the day, and where it is best to keep solar lighting fixtures. For example, using solar lamps you can illuminate trees upwards, you can illuminate flower beds or statues, or create a beautiful glow on the surface of the water in a garden fountain. You can also beautifully decorate the terraces with solar lighting, but so that the lamps do not dazzle anyone, and you can do this by setting the lamps high enough. The ideal is the use of solar lamps with a sensor, that is, a flight controller, with which we can adjust the brightness – from bright to dim and romantic.

With sun and science to the solar light

Have you ever wondered how solar lights actually work? Since the most crucial part of sunlight is a photovoltaic or solar cell, it is because of that cell that solar lights work. The photovoltaic effect made this possible. The task of a solar cell is to convert sunlight into electricity. If you didn’t know, a solar cell is made up of leeches of crystal silicone and chemicals that create negatively charged electrons in layers and positively charged spaces. Sunlight passes through the solar cell; it excites negatively charged electrons and pushes them into positively charged spaces. The positively charged spaces then transmit electron current as a direct current of electricity through the wires embedded in the solar cell to a battery in which electricity is stored until needed. During the day, the battery in the solar lamp recharges as sunlight converts to electricity. As the evening approaches and the sun sets, the solar cell stops converting sunlight.

There is a receptor in your solar light that has the ability to detect when it’s dark, and at that moment, your solar lamp lights up and illuminates the space in which it is placed. The light consists of several LEDs. At night, thanks to a rechargeable battery during the day, your solar lamp will illuminate your garden. This process is repeated daily. During the day, sunlight is converted to electricity. It recharges the battery in a solar lamp, and during the night, the battery supplies electricity to the light until it is used up. When the sun comes out, the photoreceptor turns off the light, and the battery starts charging again. In the months when the sun is strongest, your solar lamp battery will charge the fastest. Avoid placing solar lamps in places where trees and tall shrubs shade during the day. During winter, the solar lamp will not be as functional as in summer because the sun is not so strong in those months where days are shorter and nights are longer—less sunlight, less energy that can charge a battery in a solar lamp. If you live in places where there is a lot of snow, keep in mind that snow can block the solar cell and thus prevent the battery from charging.

What if your solar lights are working

  • See on the switch if your solar light is on at all.
  • If you have just purchased and installed a solar light, make sure you have removed the pull tab.
  • Try to adequately cover the panel (it must be completely dark), so you can test the light.
  • You need to clean your solar panel on a solar lamp thoroughly. If you don’t know how to do that, educate yourself on how to clean solar lights.
  • You need to position the solar lamp, so it does not stand in the shade.
  • If you feel something is wrong with a battery in a solar lamp, try inserting the most common batteries to check the functionality of the solar lamp. If it works with ordinary batteries, then the problem is with the battery in the solar lamp.
  • Some solar lamps charge the fastest by pushing the switch off. Try this procedure and do not light your lamp for the next 72 hours.
  • If none of the above helped you, contact the person or shop that sold you that solar lamp.

If you want to decorate your yard with beautiful lighting, solar lamps are always the right choice. Look at the market for the best outdoor solar lights. Keep in mind that your solar lights will not last forever, but inquire how long the solar lights last. Plan ahead where you can put your new solar lamps in the backyard to keep you happy while you enjoy being outdoor in the evenings.
