Solar lighting technology has undergone a rapid evolution throughout the years, which has significantly improved its energy conversion efficiency. Solar streetlights are becoming increasingly popular throughout the world, owing to their cost-effectiveness and compact designs.
Currently, there are two types of solar street lights available in the market – traditional street lights and all-in-one integrated LED street lights. Both of these consist of a lighting source, battery, charge controller, and solar panel. Before investing in either type, it is essential to understand the differences between the two and how the latter can be more beneficial.
What Is Integrated Solar Street Light?
An all-in-one integrated solar street light is a new generation solar-powered street light, with all components integrated within a single unit, unlike conventional solar lighting systems. It is becoming increasingly popular owing to its lightweight construction, smart features, and compact, stylish design.
Features And Advantages Of Integrated Solar Street Light
- Light Source
Solar LED street lights typically use one of two light sources – Light Emitting Diodes or LEDs and High-Intensity Discharge, or HID lights. All-in-one integrated street lights use the former since it is more beneficial.
LED lighting systems are highly efficient as compared to their alternatives, which in turn helps in the conservation of energy. In addition, LEDs are equipped with heat resistance which enhances their durability.
Due to advancements in lighting technology, modern LEDs can sustain around 200 lumens per watt. This means that these light sources can not only provide better illumination but can also reduce maintenance costs.
- Advanced Lithium-Ion Batteries
All-in-one solar street lights utilize lithium-ion batteries, as opposed to conventional solar street lights. These batteries can store more energy and can function in low temperatures of up to -30 degrees Celsius.
Since lithium-ion batteries are more efficient and can store more energy, they are perfect for use on cloudy or rainy days. Therefore, all-in-one LED solar street lights are perfect for use in areas where temperatures are hard to predict. The high-capacity lithium-ion batteries are used to ensure that the street lights last for six to eight years at the least.
- Smart Features
All-in-one solar street lights utilize either poly-crystalline or mono-crystalline solar panels. The conversion rate of the former is lower in comparison to the latter. To maximize the efficiency of the entire unit, smart features like dimming and motion sensors can be easily integrated into these street lights.
The design of all-in-one solar street lights is such that other features like CCTV cameras, time control sensors, motion control sensors, USB interface, and APP control, among others.
Structure Of Integrated Solar Street Light
The main components of an all-in-one solar street light include an integrated lamp and a lamp pole. The integrated lamp consists of a high-efficiency solar panel, high-brightness LED chips, sensors, an MPPT intelligent controller, and an anti-theft installation bracket.
Some integrated solar street lights may include other components as well, such as CCTV cameras or time control sensors. The lamp pole and exterior of the street light are water-proof. They are made of long-lasting alloy materials and so, do not corrode easily under extreme weather conditions.
Working Principle Of Integrated Solar Street Light
An all-in-one solar street light converts solar energy into electricity via its solar panels. During the day, when there is ample sunlight, the solar panels harness the sun’s energy and store it in the battery.
Once the battery is completely charged, it is automatically disconnected from the solar panel with the help of an intelligent controller to prevent it from overcharging. At night, the energy stored in the lithium-ion battery is used to power the LED light.
Unlike conventional street lights that run on electricity or traditional solar lights that stay lit the whole night, an all-in-one LED solar street light has much more to offer. An all-in-one solar street manufacturer may also integrate smart features like automatic dimming, motion sensors, and pre-set time controls, depending on lighting demand in various areas.
Why LEDs For All-In-One Solar Street Lights?
Solar energy and LED light sources are akin to a match made in heaven since they complement each other’s best attributes. While HIDs and other lighting types like CFL, HPS, or metal halide work with solar energy to an extent, LEDs are an unmatchable pair.
- Use Of DC Power
For older lighting sources, a converter or ballast is required to make the light operational. This ultimately leads to a loss in energy, which has to be compensated with a larger solar panel and battery.
Since LEDs operate on DC power, which is the battery’s natural output, an extra converter or ballast is not required, allowing the street light to operate more efficiently at a lower wattage. In fact, LED light fixtures provide the best Lumen per watt ratio.
- Better Light Output And Visibility
LEDs have a better light output compared to their alternatives, and they also produce much better lighting in a larger range of colors, from warm white to bright white light. This makes LED streetlights ideal for various environments.
In addition to better light output, bright white LEDs have a better CRI or color rendition index. This means they can provide better visibility at night, ensuring drivers can drive safely. It also makes solar street lights ideal for installation in remote areas where electricity may not be available.
Best All-In-One Solar Street Light
As mentioned above, all-in-one solar street lights offer several benefits. They are energy-efficient and environment-friendly as they do not require electricity to function. Their sleek, compact design also ensures that it is aesthetic, easy to install, and easy to maintain. Compared to normal street lights, they do not require trenches to be installed.
The risk of accidents is also minimal since these street lights use LEDs that provide better visibility and brightness at night. This ensures both pedestrian and vehicular safety at night and in remote areas.
All-in-one street lights can provide an efficiency of up to 200 lumen/watt, meaning that 80% of energy can be conserved compared to street lights that run on electricity. Since solar street lights operate off-grid, they operate at zero cost.
The best all-in-one street light will depend on several factors such as budget, the area where it is to be installed, size, durability, brightness required, and features. Other factors to consider while selecting all-in-one street lights include certification, quality, customization, safety, as well as technology.
All-in-one LED streetlights are undoubtedly the future of outdoor lighting systems as they are green, support the principles of sustainability, and are efficient. They can also be integrated with smart features like motion sensors and dimmers to maximize their efficiency.
No matter the type of all-in-one integrated LED solar street light that is selected; the benefits are several. These can be installed anywhere, be it a remote area or one with harsh weather conditions.
