Solar Lights are the future. Imagine making literal electricity out of the sun and using that electricity to power lights that turn on at your will. That’s what Solar Lights are.
But how do they actually work?
Solar lights work because of the photovoltaic effect. The solar cell is the part that converts sunlight into a direct electrical current. During the day, sunlight is converted to electricity and stored in the battery. At night, the battery supplies the electricity to the light until it is all used up or the photoreceptor shuts off the light.
The battery charges throughout the day as sunlight continues to be converted into electricity. When evening approaches, the solar cell stops converting sunlight as it weakens and disappears. A photoreceptor on the light detects when it’s dark and turns on the lights, which is usually made up of several light-emitting diodes (LEDs) This process repeats on a daily cycle and charges the battery until daylight reappears or the light shuts off as daylight reappear.
There are many advantages of Solar Lights such as:
- Renewable Energy Source
- Inexpensive Cost
- Reduces Electricity Bills
- Low Maintenance Costs
- Uses a Lot of Space
- Technology Development
Since you will be meeting some of your energy needs with the electricity your solar light has generated, your energy bills will drop. The actual solar light will also be quite inexpensive as it won’t be that large. Among all the benefits of solar panels, the most important thing is that solar energy is a completely renewable energy source. We literally cannot run out of solar energy, unlike some other sources of energy. Solar energy will be accessible as long as we have the sun, therefore sunlight will be available to us for at least 5 billion years!
The use of solar energy is going to positively affect everyone. Next time you are looking to light up an area, whether it is your backyard or a large parking lot, look into solar lighting as your first option and make a positive impact on both the environment and the area you are lighting.
