A solar street light is an effective outdoor lighting source operated through the use of solar energy. Solar Street Light is a recent technological innovation for lighting solutions, powered by photovoltaic (PV) panels. The PV panels having rechargeable batteries are fixed on the lighting structure or in the pole to provide power supply to the solar LED street light or street lamp during the night.
The solar panels or PV panels are designed in such a way to feed natural light source or sunlight. This enables the street light to provide sufficient light during the night, or cloudy days even for a couple of days when the sun’s energy is not available. People are switching to solar street lights these days due to several causes such as lesser maintenance, environment-friendly, eliminates your carbon footprints contribution, and handy solutions to lighting problems. Even solar street lights in India is also popular only because of these reasons. SolarClue is an online platform where people can find several solar street light manufacturers to purchase their preferred street light at different pricing portfolios.
Components of Solar Street Light
Solar Street Light is manufactured using five components, such as Solar Panel, Lighting Fixture, Rechargeable Battery, Controller, and Pole.
Solar Panel or PV Panel: - It is the main component of the solar street light that helps to convert solar energy into electricity. The solar panel is divided into two different types, mono-crystalline, and poly-crystalline.
Lighting Fixture: - Lighting fixtures like LED is another component used in solar street light that helps in providing much higher Lumens (total amount of visible light from a lamp or light source) with lower consumption of power. The primary benefit of an LED fixture is to consume energy consumption of about 50% lesser than the HPS fixture.
Rechargeable Battery: - It is used in collecting electricity from solar panels and stores it during the day time to provide power supply to the fixture during the night. Gel Cell Deep Cycle Battery and Lead Acid Battery are two different types of rechargeable batteries.
Controller: - It is also a crucial element of a solar street light. A controller is a vital part that decides when to switch on or off the charging battery and lighting system.
Pole: - It is an essential part of a solar street lighting system. Pole is built-in supporting the fixtures, panels, and batteries as they get mounted on the top of the pole.
Types of Solar Street Lights
There is a total of four types of solar street lights available in the market.
1.Off-Grid Split Type Solar Street Light System
2.Grid-Tie Solar Street Light System (Grid-Tie Single Inverter, Grid-Tie Micro-Inverter)
3.Solar & Wind Hybrid Solar Street Light System
4.All-In-One Solar Street Light System
Working Principle or Functionalities of Solar Street Light
The optimum functionality of solar street light is to offering lightning solutions at night for several streets and by using natural energy called sunlight. A solar street light is generally functioned by PV solar cells that convert the energy of sunlight into electrical energy by the use of the semiconductor material of the device. This entire process of energy conversion (called a photovoltaic effect or Photovoltaic cells) is used in storing solar power in batteries during the day and provides proper light at night with illumination reduced to 10lux.
After this, the solar cells board is used to open the circuit voltage of about 4.5V. Then the charging and discharging controller is used to protect the battery and detects movement of the voltage value. This entire process is the working principle of solar street lights.
Advantages of Solar Street Light
•The operation cost is inexpensive as the solar street light independently works
•Known as a pollution-free source of producing electricity to offer lighting solutions
•It is used not by utilizing any external wires hence, negligible chances of occurrence of accidents happened
•It has lower chances of overheating
•Easy accessibility of smart street light in remote areas because the parts of this lighting system carry easily.
