FACTORS AFFECTING THE 20W SOLAR STREET LIGHT PRICE

Green Energy mostly comes from the wind, water, and sun. While all three can help, solar energy has gotten the most attention as a practical means to curb energy requirements and protect the environment.

Government initiatives and widespread use of solar illumination technologies, such as solar street lights, are driving the change on a worldwide scale. To reduce greenhouse gas emissions, the global community is concentrating on renewable energy sources. Solar street lights are becoming increasingly popular as a result of society’s insatiable want for green energy. Take a look at the evidence below: By 2027, the global market for solar-powered street lights is expected to be worth $14 billion, with a compound annual growth rate (CAGR) of 14.7% post-COVID as per the Global Industry Analysts.

THINGS AFFECTING THE PRICING OF SOLAR ROAD/STREET LIGHTS

1. THE LIGHT SOURCE

People looking for solar-powered light sources may choose from a number of solutions when they inquire with solar street light vendors.

  • Light bulbs that conserve energy
  • LED lights
  • LED induction lights
  • Light bulbs that use sodium vapor

The LED light is the greatest of these options since its spectrum is the closest to that of the sun. Smart solar-powered LED lights today have greater lumen output while consuming less electricity than earlier. Additionally, LED lighting makes it easy to switch to solar energy. They may thus be the preferable option.

2. BATTERY TYPE

There are two kinds of batteries used in solar lamps.

  • lithium-ion batteries
  • Standardized lead-acid batteries

When comparing the two, lithium batteries offer the following advantages:

  • Improved longevity
  • Better thermal stability (upto 45 degrees Celsius)
  • Periods of charging and discharging might vary ( up to three times more than that of lead batteries)
  • Increased battery life for optimal lighting performance

One thing to keep in mind is that the battery life needs to coincide with the minimum required illumination efficiency. In that case, the street lamp will not give out enough light during the rainy season. Better the stability and battery life, more money it will cost.

3. THE TEMPERATURE AND LATITUDE

At latitudes higher than 15 degrees, the sun’s inclination angle with the ground is more than 15 degrees. Consequently, you should think about solar-powered streetlights with flexible solar panels. Solar panels for roadway lighting shouldn’t be put in a way that they’re facing in the wrong direction, either. Thus, latitude and proper placing are important for more efficiency.

4. THE HEAT DISSIPATION PERFORMANCE

The efficiency with which the LED bulb dissipates heat is also a major component in evaluating its overall quality and price. Dissipation of heat is simply the movement of heat from one place to another. Dissipation, however, can also mean heat loss caused by unfavorable circumstances. Since the life of the semiconductor device in the street lamp is limited if there is insufficient heat dissipation. Anti-ultraviolet and fireproof LED lights are the best option for safe lighting because of their superior heat dissipation properties.

5. THE DEGREES OF LIGHT

Consider the footcandles while shopping for solar street lights. This metric is how bright the ground will be. In a perfect world, the contrast between light and dark would be 4:1; yet, even a 3:1 contrast would be satisfactory. 

6. THE BLACK LAMP CASE’S TEMPERATURE

Since black bulbs absorb a lot of heat, white ones are a better choice. Underexposure can cause the metal casing of a black bulb to reach temperatures of up to 90 degrees Celsius. The battery and LED light source will be ruined by the extreme heat. Therefore, silver is the best choice since it does not fade or heat up while left outside.

7. THE CONTROLLER

These devices, also known as solar controllers, coordinate the activities of solar panels, storage batteries, and loads. When deciding on a controller, an efficient heat dissipation function is essential. Temperature adjustment is another must-have function. Solar batteries may now be protected from overcharging and undercharging due to installing a smart controller. Better still, invest in a solar controller that can be monitored and controlled in real-time via built-in connectivity. With this controller, you can expect top-notch functionality and reliable service for a long time.

You may learn more about the longevity and dependability of a solar street light system by looking into its light source, controller, and lighting fixture material. Depending on how many bulbs need to be changed, there may be an installation fee with 20w solar street light price. Because solar-powered streetlights don’t need regular servicing, you won’t have to spend money keeping them running. Solar streetlights are now available in a wide range, making it possible to choose the perfect option for every application, from decorative lighting to pathway illumination.

Each solar street light has a wattage and lumens rating that can be checked out online, which also decides the pricing of the street light. Before making a final decision on solar street lights, it is a good idea to discuss 20w solar street light price with the retailer and learn about the expected lifespan of the product. It’s impossible to make a poor judgment regarding switching to solar illumination once you know the fundamentals of how solar street lights work and their technical aspects.
