How Does Solar Lighting Work?

The world is pushing for more renewable energy to avoid the adverse effects of climate change. According to World Energy, just the average global solar radiation per year can produce just as much energy needed as 140 m3 of natural gas, 200 kg of coal, or a barrel of oil. This means, under the right optimisation process, solar energy can indeed replace modern energy sources we have today.


Solar LED lights


Solar LED lights are incredibly efficient in the same way standard solar energy is efficient. In addition, solar LED lights are entirely off-grid and incorporate battery technology.

If we’re to talk about the basics, it’s evident that solar LED street lights work by utilising solar energy – however, it doesn’t stop there. These street lights depend on photovoltaic cells, which are responsible for absorbing solar energy during the daytime. These cells convert solar energy into usable electrical energy that can power the lamps during nighttime. This process repeats daily and can become a sustainable energy source for the streetlight while the sun is up.

Solar LED street lights rely on the photovoltaic process, which allows the solar cell to convert sunlight into usable electrical energy. Sunlight is converted when negatively-charged electrons push solar energy into positively-charged spaces in the cells. This process allows solar energy to transfer into the electrons – becoming direct current electricity. Wires from the solar cell are then connected to the battery to transfer the new direct current electricity from sunlight.

It’s when night arrives that the solar cell will stop the conversion process as sunlight disappears. Photoreceptors will help shut the solar cell down when there’s not enough sunlight to convert. This is when the battery will start supplying power to the LED lamp via wiring.

Solar LED street lights work in all areas, making them ideal for areas with limited access to power. In addition, the portable and environmentally friendly nature of a solar LED street light can make them an excellent replacement for ordinary street lights and a good option for areas with no access or limited access to an electrical grid.
