What is Solar Light?
Solar lights are an innovative product that integrates all solar components into just one solution. There is a highly efficient solar panel, several LED bulbs, a rechargeable solar battery (lithium-ion), a mounting structure, and other small solar accessories. These lights are significantly more efficient and reliable in operation as a family of next-generation solar luminaires that work on the photovoltaic effect. Solar lights work independently without a grid and don’t require heavy wirings, making them extremely safe and convenient
The solar light has a compact design to let you handle it most efficiently. There are many advancements in solar light technology in the last few years. Every technological breakthrough has improved the efficiency and reliability of these lighting. The popularity of these lights is getting increase day by day because of their wide applications and huge benefits. Solar lights can be used at any place whether as an interior or as an exterior.
How does solar light works?
As the name suggests, solar lights run on solar energy. To generate this solar power, a solar panel is connected to the solar light. The panel absorbs the sunlight during the daytime and convert that sunlight into electrical energy which is stored in a solar battery. At night time the solar light starts automatically and consumes the electricity already stored in the solar battery. In the daytime, the light turns off and starts again battery charging. The system continues its same cycle on daily basis for years and years throughout its lifetime.
Let’s understand it technically. When the sun goes down, the solar panel will no longer generate electricity and so the battery will stop charging. There is an inbuilt charge controller which detects this moment and gives the signal to the light to switch it on. Firstly, the light starts at 30% of power in eco mode. When the Dusk-to-Down/PIR sensor detects a movement, it activates the light to full power at 100%. After any movement is not detected for at least 20 seconds the light power will reset to 30% brightness. The next day when the sun starts to shine, the solar panel starts to give a signal to the controller and the light will be switched off automatically.
Types of Solar Light
Solar lights are no longer limited to the sides of the roads, thanks to advancements in solar technologies. Now you will get to see many types of solar lights. Whether it is your home, any institute, bus stand, or airport, you will find solar lights installed everywhere. After all, how many types of solar lights are there, which are being used everywhere. Let’s know about the types of solar lights.
Solar Street Light

Solar Street lights are also known as stand-alone or battery-based street lights. In solar street lights, solar panel and solar LEDs are integrated on a pole. The main work of the solar panel is to convert sunlight into electricity by using a photo-voltaic effect. A normal size solar street light can cover around a 10 to 15-meter area for illumination.
There is a wide range of solar street lights available in the market such as 9 watt, 12 watt, 15 watt, 18 watt, and 24 watt street lights. These lights are an economic and eco-friendly method of illumination.
Solar Home Lights

Solar home lights are a modern way to power your home. In a home solar lighting system, the solar panel is mostly get installed on the roof of a home. In day time solar panel will generate electricity and store it in the solar battery. This stored power can be used when there is no grid or your solar panel is not generating electricity during the night or cloudy days. Unlike other traditional exterior lights, these solar lights need no complicated setup.
Just like solar street lights, solar home lights are also available in various capacities and ratings. The home solar lights are available in 18 watt, 20 watt, 30 watt, 75 watt capacities. You can install any capacity solar home lighting system at your home as per your need or power requirement.
Solar Garden Light
Solar garden lights are the best way to give your garden a designer look and make it attractive. There is no restriction to use solar light anywhere. Just like solar lights can be used in homes, similarly, solar lights can also be used in gardens. You often see solar lights installed in gardens.
Solar garden lights on one side will provide a low-cost illumination and on the other hand, it also increases the beauty of your garden. These lights are charged in the daytime and automatically powered up at night. A solar panel that comes along with the solar garden light will generate electricity in days and during nights the light will power up by using the same solar power/electricity.
Solar Lamps & Lanterns
Solar lamps are also a popular type of solar light. These lights come with an inbuilt solar battery that can be charged with solar power. These are very attractive lights and also easy to lift and carry. Even though it may be small in appearance, but in terms of power backup, it is not less than anyone. Solar LED lamps, solar camping lanterns, hand crank solar lanterns, solar outdoor lamps, and solar cabinet lanterns are all types of solar lanterns or solar lamps.
Solar Emergency Light
Solar emergency lights are designed with a feature of low power consumption. This feature helps these lights to provide at least 5 to 7 hours of power backup for emergency purposes. Solar emergency lights are a user-friendly solar product that can be turned on and turn off very easily.
Solar emergency lanterns are the best power backup option during electricity cuts and limited exposure to sunlight due to monsoon or bad weather. This solar light also can be used in extremely problematic situations like natural calamities and disasters where there is no option of power connectivity.
