A solar lamp, also known as a solar light or solar lantern, is a lighting system composed of an LED lamp, solar panels, battery, charge controller,LED controller and there may also be an inverter. The lamp operates on electricity from batteries, charged through the use of solar panel.
Working of Solar Lamp
Solar panel is convert solar energy into electrical energy by Photovoltaic effect. Solar panel provide electrical energy to battery.battery charging is controlled by charge controller.Battery provide electrical energy to LED lamp. This is simple process of solar lamp.
Network of Solar Lightning system
The design of a Solar Powered LED System is basically the same as design for an off-grid solar power system . Here the PV array is used to convert sunlight energy to electrical energy in Direct Current (DC) mode.
Solar Charger is used to control the charging of the battery bank. The battery bank is used to store the electrical energy provided by the PV array, as well as supplying the electrical energy to the load when there is insufficient sunlight for the PV array to generate electricity for the system.
LED Controller plays an important role in this design. Utilizing a PIR Motion Sensor, it controls the light intensity of the LED lamp when there is motion near the structure. When there is no signal from the sensor, the LED lamp will be dimmed at 70% of its light intensity.
When the motion sensor senses movement, it will cause the controller to increase the light intensity of the LED lamp to 100%. Lastly, LED lamp is the load for the system. LED lamp is chosen compared to other types such as vapor or halide because of its low power consumption and higher lifespan.
Benefits of Solar lightning
Solar lights are extremely cost-effective. Many corporations, businesses, cities, etc. have saved thousands of dollars up-front and over time because of no grid-tie connections and no energy bills over time.
Solar lights are more secure—in times of emergency or a power failure, these lights stay on since there’s no connectivity to power grids that are liable to fail.
Versatility. Solar lighting works well for remote areas, cities, construction sites, parks, streetways, and other areas. Some models are portable, so you can move them wherever needed.
No trenching. Solar lighting systems don’t need trenching to connect to power, so the grounds in the area can be kept intact—this is important for parks and protected lands.
No electricity bills. You needn’t worry about lighting bills with solar since the panels draw free electricity from the sun!
Solar energy is one of the cleanest forms of energy. There are no emissions or by-products from generating energy from the sun.

Frequently Asked Question(FAQ)
How many types of Solar lamps?
There are 2 types of Solar lamps. Indoor Solar lamp and Outdoor solar lamp.
How do solar lamps work?
Solar lamps contain solar panels that convert sunlight into electricity, which is then stored in a battery. This electricity powers the light emitting diodes (LEDs) in the lamp, providing illumination.
Do solar lamps work in cloudy weather?
Solar lamps can still work in cloudy weather, but they may not charge as efficiently or provide as much light compared to sunny conditions. It’s important to place the solar panel in a location that receives adequate sunlight.
Which solar panel is suitable for LED street lights?
Both monocrystalline and polycrystalline solar panels are used to support solar street lights. However, polycrystalline solar panels are more in demand because they are cheaper and the efficiency does not reduce with changes in ambient temperature.
What kind of batteries are used in solar street lights?
Lead acid was the popular choice of batteries for solar street light earlier as they were relatively inexpensive and were available for a variety of applications.
What is the lifespan of solar lamp?
The lifespan of a solar lamp depends on factors such as the quality of the components and how well it is maintained. Generally, solar lamps can last anywhere from 2 to 5 years or more.
Are solar lamps waterproof?
Most solar lamps are designed to be weatherproof, meaning they can withstand rain and other outdoor elements. However, it’s always a good idea to check the product specifications to ensure it meets your needs.
Do solar lamps have a switch to turn them on and off?
Yes, most solar lamps have a switch to manually turn them on and off. Some models also come with automatic sensors that turn the light on at dusk and off at dawn.
What kind of maintenance should be done on solar street lights?
Regular maintenance of your solar lamp includes cleaning the solar panel to ensure maximum sunlight absorption, checking and replacing the battery when needed, and keeping the light fixture clean.
