What are Solar Lights? And How do they work?


What are solar lights:

In scientific terms 'Solar Lights' are portable light fixtures which includes LED lamps, photo-voltaic solar panels and rechargeable batteries. In simple terms solar means the sun and lighting means to provide light. So, solar light is the light which is produced with the help of sun's energy.

A solar light uses energy from the sun to produce light. (Solar light can also refer to natural light coming from the sun.) There are inexpensive lights that you can place outside.

Tapetum India Solar was founded with the objective of promoting energy-efficient solar LED lights.  Tapetum is an ISO 9001:2015 and ISO 10002:2004 certified company and is now a leader in distributing cost-effective solar-powered lighting solutions to individuals and dealers. The products sold by Tapetum are durable and designed to meet global standards. Each product undergoes meticulous testing and inspection by the in-house quality experts before being distributed.

How Do Solar lights work?

Solar lights work on the principle of photovoltaic effect. Solar panels absorb sunlight with the help of solar cells and convert this solar energy into direct electrical current which is stored into solar batteries via a charge controller for later use. A single solar cell is capable of producing a maximum of 0.45 volts and the current generated depends on the size of the cell and the amount of sunlight striking the solar panel.

When the sun is out, a solar panel takes the light from the sun and produces electrical energy. 

The energy can then be used immediately or stored in a battery. The goal of most solar lights is to provide power at night, so they will definitely contain a battery, or be capable of attaching to a battery.

Solar panels are wired directly to the battery through a charge controller, which protects the battery by preventing the backflow of current through the solar cell at night and regulating the voltage. Solar cells stop the conversion process and stop producing power at nighttime. When there is no sufficient sunlight to convert, photoreceptors on the light sense it and start supplying power to the LED. The photoreceptor shuts off the light automatically at daybreak and this process gets repeated on a daily basis.

How Do Solar lights Turn On At Night?

A photoreceptor on the light detects when it's dark and turns on the light, which is usually made up of several light-emitting diodes (LEDs). The battery then supplies electricity to the light throughout the night. This process repeats on a daily cycle.
