Solar Lights: What Are They And How Do They Work?

September 15, 2020

Lighting can make a difference in any space, but they can sometimes be inefficient. Lighting outdoors can be just as important as indoor lighting and needs to be chosen wisely to fit your needs. While traditional on/off switch lights have been a popular choice for a long time, the benefits of solar lights have appealed to many. Solar lights are an efficient and cost effective way to add outdoor lighting to your home or business. So, what exactly are solar lights? And, how do they work?

What Are They?

Solar lights are just as they sound, they are lights powered by the sun. Solar lights are often used outside to collect solar energy during the day and use that energy when it turns dark at night. Many of these solar lights turn on automatically and are on all night, but some use motion sensing technology to only turn on when it detects motion nearby. One of the greatest benefits of solar powered lights is that they are self sufficient and require little maintenance. While you may need to clean them sometimes, you do not need to frequently need to replace batteries or turn them manually on and off. Overall, solar lights are energy efficient and super convenient for the owner. 

How Do Solar Lights Work?

These amazing lights are so convenient and work so well, but how? Solar lights work by collecting the energy from the sun into the photovoltaic cell or “solar cell.” This solar cell is the darker part of the light that may have thin lines running through it. This cell is made up of silicone that is in a crystalline structure. The cell is made up of areas of negatively charged particles and areas or positively charged particles. As the sun’s rays are shone onto the solar cell it gets the electrons into an excitable state and is passed along into positive areas and then through a channel such as a wire to the holding cell. As the electrons continue to build up throughout the day they are collected into a holding area to then be used once it is night time. Solar lights have been inspired by the way plants harness energy from the sun. Overall, the science and technology of solar lights has made them possible to positively impact our lives on a daily basis. 

Where To Put Solar Lights

Solar lights can be put in many places. If you wanted to get wild and crazy you could place them around your entire yard, but there are some more practical places you could put them. When choosing where to put your solar powered lights you have to keep a few things in mind. Number one is that you need it to be in a spot that gets a lot of sunlight. Without adequate sunlight your solar lights will not get adequate charge and will not be very bright and may not even put on. Another thing to keep in mind is that it is providing light to an important area, but it is not getting in the way. You want the light to be in a safe location where it will light your path, but not be a tripping or fall hazard. Below are some common places that solar lights can be placed. 

Walking Path

Walking up to your house at night can be scary if you do not have a light to guide your way. You may trip and fall on something that you didn't know was there, like the soccer ball you told your child to put away earlier. Solar lights are perfect to place along a walking path to brighten up the path and prevent any unwanted accidents. In addition to being a safety precaution, it is also a design element of your home to highlight its features, even at night. A great option for the walking path is a LumiGuard™ Pro Solar LED Security Light from Boundery. This is a motion sensing light that can be mounted to a post in front of your house to light the way as you walk by. Walking path lights are perfect for right by the door or to lead you or your guests into the safety and comfort of your home. 

Garden

People put hundreds of dollars into their gardens and is a large addition to the curb appeal of any home. Just because it is dark outside doesn’t mean you should not be able to enjoy it. Adding a solar powered light to your garden can power up during the day to showcase your beautiful landscaping at night. In addition, if you decide to use a motion detecting solar light it can turn on if any critters come in the garden at night deter them from coming back and to notify you that something has been detected. Using solar lights in the garden has multiple purposes and is a smart way to include solar lighting around your home. 

On The Stairs

LED stair lighting has been shown to increase the safety of walking up and down the stairs and are recommended as the light of choice. Walking on the stairs without adequate lighting can lead to falls, trips, and ultimately injuries. This is especially true if you are outside and the surface is uneven or slippery from precipitation. Adding the Boundery solar LED stair lights can automatically add lighting to your outdoor stairs at night time so that you can feel safe moving about your grounds. This is perfect for those late nights sitting out on the deck or porch just spending time with the family and can make the experience even more carefree. Outdoor solar stair lights are a game changer for night time visibility. 

Basic photovoltaic cells were created in 1954 by Daryl Chapin, Calvin Fuller, and Gerald Pearson. Since then solar cells have been integrated into many things from solar pool heaters to an automatic solar light. With constant creativity and innovation these solar lights were made possible to be your security and increase safety around your home. Now that you know what they are and how they are made, how will you integrate them best into your life?
