Definition of Solar Street Light
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.
What is solar panel and how it works?
Solar Panel is also known as Photovoltaic Solar Panel, made using smaller units of silicon. This is called a solar cell, which converts solar energy into electrical energy. Silicon is a semiconductor inserted between conductive layers in a solar cell.
How solar panels work? The process of solar paneling starts during the day time when proper sunlight is there. The sun rays fall on Solar PV Panels that are installed on your rooftop, and photovoltaic refers to the scientific process by which solar energy gets converted into electrical energy.
There are several silicon cells within each PV panel, and these cells react with photons (unit of light), which come from the sun to produce DC (Direct Current) or electricity. The direct current (DC) then travels into an inverter that converts it into AC (Alternating Current), which further used in your home, office, playgrounds and many other places. After this, AC current transfers to the distribution network in your home, which is capable of powering electrical appliances of your house. When Solar Panels produce more electricity than your home is using, the extra electricity gets shifted or stored in the grid. And, you can avail of the benefits for the extra electricity that your solar panels generate. Moreover, solar panels are available in different sizes and price ranges.
Solar Panel Price in India

There are different categories and pricing of solar panels in India available with SolarClue, and according to those classifications customers can choose their items. They also can compare solar panel prices and select the best one which suits their budget.
Working Principle of Solar Panels
Solar Panels work on the principle of the photovoltaic effect, which is a method of producing direct current electricity based on the principle of the photoelectric effect. Photovoltaic directly converts solar energy (sunlight) into electricity. When certain materials expose to sunlight they absorb photons and then release free electrons, and this phenomenon is called the photoelectric effect.
Solar cells or photovoltaic cells are used to convert sunlight into direct current (DC) electricity. Though a single photovoltaic cell does not produce enough amount of electricity, hence several photovoltaic cells are mounted on a supporting frame and electrically connected to form a photovoltaic module or solar panel. The current or electricity that solar panel system provide is dependent on the effectiveness of sun rays.
Types of Solar Panels
Solar Panels are classified into two types such as Monocrystalline Solar Panels and Polycrystalline Solar Panels.
Monocrystalline Solar Panels:
Monocrystalline Solar Panels are made using extremely pure mono (single) silicon crystal that helps in converting solar energy into electricity. Monocrystalline solar panels are suitable for easy installation in smaller areas, which requires a reasonable price. However, the monocrystalline solar panel installation is ideal for a larger area, but it makes it expensive. Users will be able to get the most electricity output according to the monocrystalline panels used.
Polycrystalline Solar Panels:
Polycrystalline solar panels are made using poly (multiple) silicon crystals and known as the most commonly used type due to price and efficiency. The cells used in Polycrystalline are a small amount of quantity that makes the Polycrystalline Solar Panels a bit less efficient. For this reason, users can install a large number of polycrystalline panels to generate electricity to meet their consumption needs. As compared to Monocrystalline Solar Panel, Polycrystalline Solar Panel is considered the commonly used type as they maintain a good balance between pricing and effectiveness.
Difference between Monocrystalline and Polycrystalline Solar Panel
The difference between Monocrystalline and Polycrystalline solar panels is the advanced technology that has made them practically interchangeable. Owing to the manufacturing process and robust technology, Monocrystalline Panels are quite expensive as compare to Polycrystalline Panels. The monocrystalline solar panel comes with black and dark blue color, whereas polycrystalline panel appears in the blue mottled.
Monocrystalline Solar Panels are more efficient than polycrystalline solar panels thus, you can use slightly more power in the same size and space of monocrystalline panels. But polycrystalline panels need more equipment to produce the same amount of electrical energy as monocrystalline. For this reason, the solar panel cost is less for polycrystalline. Interested buyers can purchase any solar panel through online and also by visiting stores.
When it comes to temperature, Monocrystalline panels handle the heat slightly better than polycrystalline solar panels. This temperature difference can be noticeable especially in extremely hot areas such as deserts, as compared to residential regions. Last but not least, monocrystalline can perform in a better way even on hazy skies than polycrystalline panels.
A solar battery is simply a
battery charged and stored with solar power or energy and discharges power or
solar electricity when needed. Solar batteries are rechargeable and used in
off-grid PV systems to store excess electricity for future use. Some categories
of solar battery banks use wet cells, whereas others use sealed or gel cell
batteries and both the categories of batteries have their different
requirements in terms of temperature, mounting, and ventilation.
