Lighting fixtures eats a big chunk of one’s average electricity bills. There’s light in every room of the house and they are usually turned on for several hours each night and sometimes, even when it’s daytime. Because of this, many property owners are choosing to invest in lighting fixtures or systems that wouldn’t cost them a lot of money. One of these options is solar lights.
Solar Lights
Solar lights are an environmentally friendly substitute to traditional lighting fixtures or systems.
Solar lights work due to the photovoltaic effect. The photovoltaic or solar cell is the most important part of a solar light. This is the feature that converts sunlight into direct electrical current. A solar cell is composed of multiple layers of crystalline silicone and various chemicals that create layers of negatively-charged electrons and positively-charged spaces. When sunlight passes through the solar cell, it stimulates the negatively-charged electrons and pushes them into the positively-charged spaces.
The positively-charged spaces then transfer the electron stream as a direct current of electricity through wires implanted into the solar cell to a battery where the electricity is stored until it’s needed. The battery then charges throughout the day as sunlight continues to be converted to electricity.
During nighttime or when natural light fades, the solar cell stops converting sunlight as it weakens and eventually disappears. A photoreceptor on the light detects when it’s dark and automatically turns on the light, which is usually made up of several light-emitting diodes or LEDs. The battery then supplies electricity to the light throughout the night or as long as it’s dark. When daylight reappears, the photoreceptor shuts off the light and the whole cycle begins again.
