Solar energy has many commercial, industrial, and residential uses. This type of energy can be used for heating, cooling, mechanical propulsion, and providing power for equipment and machines. Solar energy can also be used to provide light for home and business use. Solar lighting comes in many forms and can be an economical way to illuminate the exterior of your home or office building. Keep reading to find out more about how solar lighting works and how it can help you save money and protect the environment.
Solar lighting comes in many forms, but in its basic form, it consists of a light or lamp that looks similar to a light that runs on electricity. Inside the light are several components that help to make solar lighting possible. These components include an LED light source, solar cells, one Nicad battery, a controller board, and a photoresistor that can determine when it is dark out. All of these components work together to produce solar lighting.
The way solar lighting is produced involves the use of solar cells. Solar cells contain silicon and create an electrical charge with the addition of phosphorus and boron. This continued process creates energy. In a solar lighting component, there are usually four solar cells because one solar cell cannot create enough energy to provide proper lighting. The solar cells are wired to the Nicad battery so that the battery charges during the day and stops charging at night. The battery can store energy during the day that is later used for illumination purposes. Once nightfall comes, the solar cells no longer produce energy, so the photoresistor activates the LED component of the light and solar lighting is produced.
There are several benefits of solar lighting when applied to residential and commercial properties. One benefit of solar lighting is that it is a very economical way to illuminate the outside of your home or business. Because the photoresistor does not activate the LED until darkness falls, the light is not constantly on and using energy. It’s more economical to use solar lighting because a solar light uses energy from the sun to produce energy for light. There is no electricity used, which means that extensive use of solar lighting can help cut your utility costs. Another benefit of using solar lighting is that you can help to protect the environment. When you use solar lighting, you are using a renewable energy source, which means that you don’t have to worry about using up a natural resource. Solar lighting is also a very clean method of energy production. There are no harmful byproducts or pollutants released into the air and water supplies, making solar lighting a safe choice.
Like any lighting method, solar lighting does have a few disadvantages. Because solar lighting relies on solar cells for the production of energy, these lights have a very small potential for illumination. They are not ideal as main sources of outdoor light. Solar lighting is better used for marking walkways and paths to prevent people from getting off course and injuring themselves. If you want to illuminate the entire exterior of your home, other lighting options would provide more light. Another disadvantage of solar lighting is that solar lighting units are still considered to be expensive, even though they have come down in price from when they were first introduced.
Because solar lighting involves the use of solar cells and Nicad batteries, the cost per light is fairly steep. If you have the money and are able to purchase several solar lights at $10 to $20 each, then you may recoup your investment in reduced utility bills. However, solar lighting users must understand that solar lights do not provide a lot of illumination and may not be worth the steep investment if they are only to be used once in a while.
