How Do Solar Lights Work | Spotlights or Floodlights

The radiant heat and energy emitting from the sun are known as solar energy. Over the years, people have found ways to harness that energy and use it for their own good. Solar energy is an excellent way to achieve a lot of things. It not only serves as a great power source for lights, but it can also be used with cookers and heaters.

To put it simply, Solar lights use the energy from the sun and convert it into electricity using the solar panel that comes with the unit. The solar panel consists of photovoltaic cells. These cells have the capacity to absorb sunlight and store it for later conversion and use.

The photovoltaic cell is the main component of this entire process. In the presence of sunlight, the cell excites the electrons present in the layers of silicone and chemicals. As we know, electrons are negatively charged particles, and when excited, they move to the positive spaces of the cell.

Then the electron stream is transferred in the form of direct current through the wires of the cell and travels to the battery. The function of the battery is to contain the electricity until you need to use it. Since everything is automated, you do not need to worry about an on or off switch. Do you know how does flood light works?

When the sun goes down, this process of energy conversion stops as the cells stop receiving sunlight. Usually, both solar flood lights and spotlight have a photoreceptor attached to the unit. The job of the photoreceptor is to detect the presence of the sun or any other form of light.

At this time, the LED in the unit lights up, getting the signal from the photoreceptor, and you get light. When the sun comes up again, the lights turn off automatically and start converting and storing energy. This entire process repeats on a daily basis with solar lights, whether it is a led flood light, solar flood light or a spot light.

Now that you know how a solar light works, it might be worthwhile to take a look at some of the benefits. 

Eco-Friendly

The best reason to go with solar lights is that it is environmentally friendly. Spotlights or floodlights, whatever it is; you would have to spend a decent amount for installation and purchase. But when you think about how much you save on electricity; the start-up cost is negligible. They are suitable for anywhere like poolside area, massive parking lot, outdoor playing ground, etc. Furthermore, since the energy is renewable, you do not need to worry about running out of power.

Durability

Despite the popular belief, solar lights are, in fact, quite durable. The panels themselves are protected against any weather conditions. You also get protective back panels to further enhance the durability of the units.
