All Types of Solar Street Lights Review

Choosing a suitable solar-led street light for outdoor lighting projects is quite challenging especially if there are too many solar street lamp styles to choose from in the market. Other than that, the price of these solar street lights ranges from tens of dollars to hundreds of dollars or even more expensive. The cheap types are sometimes for household use, while the high-quality ones are for engineering use. Your goal now is to choose a solar street light suitable to your project and budget. But, how do you do that? Don’t worry we got your back. Through this article, we will help you choose the best solar street light for your solar street light project without spending beyond your budget.

Outdoor Solar Street Lights Classifications

In appearance, we can divide solar street lights into integrated solar street lights, all in two solar street lights and split solar street lights.

All-in-one street lights are also called all-in-one solar street lights, which means that all components are made in one shell. The advantage of the integrated solar light is easy to install. Semi-split solar lights are solar panels installed separately, and other accessories are all in one shell.

According to the quality, the solar lighting system can also be divided into a low-voltage system (3v) and a high-voltage system (12/24V). 3v solar lights are usually used in cheap low-wattage retail solar lamps. High-quality solar street light projects usually require a 12/24V system.

Outdoor Solar Street Lights Classifications

In appearance, we can divide solar street lights into integrated solar street lights, all in two solar street lights and split solar street lights.

All-in-one solar street lights are recognized as the new generation of integrated solar LED street lights, which means that all components are made in one shell. Its advantage is, it is easy to install and ship. Due to the limitation of the size, the best power of integrated solar lamps is under 80W.

Semi-split solar lights are solar panels installed separately, and other accessories are all in one shell. This kind of solar light has adjustable solar panels. Additionally, we can install semi-split solar lamps with higher power outputs than integrated solar lights, such as 100W.

Split solar street lights mean the solar panel, battery, and LED light fixtures are all installed separately. We can install the biggest power solar panel to get the brightness of solar street lights, 150W 28000lm for example.

3V 12V 24V Solar-Powered Street Lights

According to the quality, the solar lighting system can also be divided into a low-voltage system (3v) and a high-voltage system (12/24V). Usually, the 3v solar lights are used in cheap low-wattage retail solar lamps. On the other hand, high-quality solar street light projects usually require a 12/24V system.

Four Mains Solar Light Components

The picture above is the circuit diagram of all solar lights. As you can see, all solar lights must contain four components: solar panels, batteries, controllers, and LED lights. Let’s take a quick overview of each important component of solar light.

The solar charge controller is used to control the coordinated operation of these three components: solar panel, battery, LED, and other accessories. It is generally divided into PWM controllers and MPPT controllers. In rainy weather, the MPPT controller’s efficiency is higher compared to the PWM controller. For more information about solar light controllers, click here.

The battery is the energy storage component of the solar lamp system. At present, most solar light batteries are lithium batteries. Lithium batteries can be divided into LiFePO4 and LiMn2O4. We can say that battery is the most important part of solar lights. For engineering projects specifically, the cost of the battery takes part nearly ¼ to ⅓ the cost of the whole solar lights.

Solar panels are components for generating electricity. In fact, most solar street lights have monocrystalline solar panels. For further information about the solar panel, click here.

LED lights are now known as the third-generation LED light source. The fact that LEDs have a high luminous efficiency is precisely what makes solar street lighting much less expensive. At present, specifically in 2022, the luminous efficiency of LED chips can be as high as 200 lumens per watt. To learn more about outdoor solar light design and proposal, click here.

How to Choose the Best Solar Street Lights/Types of Solar Street Lamps Reviews

To make it easier for you to choose the best solar street lights, we have listed several popular solar outdoor street lights and evaluated them from different aspects, including brightness, lighting time, and lifespan. These are the following:

Cheap Price Solar Road Lamps

• Price: $30-$100
• Lighting time:  3/10
• Lighting Span: 3/10
• Brightness:      3/10

In the market, these types of solar lights are labeled 100W to 400W. However, the real lead power ranges from 5 to 25W. Additionally, all of the solar lighting parts are cheap and can only last for two years. This kind of lamp basically uses a 3V low voltage system. It is popular among home/house lighting, community, and country road. Typically, these lamps are sold in regions like Southeast Asia, Africa, and South America.

• Price: $10-$30
• Lighting time:  3/10
• Lighting Span: 3/10
• Brightness:      2/10

In the market, these types of solar lights are labeled 30W to 200W. But the real LED power ranges from 3W to 10W. The application place and target countries of this type of solar lamp are similar to the above type of solar lights.

High-Quality Solar-LED Street Lamps for Engineering Projects

• Price: $50-$500
• Lighting time:  8/10
• Lighting Span: 8/10
• Brightness:      8/10

This is the most popular solar street light which is called the “all-in-one solar street light“. The real lead power of this type can be 5W to 100W. Additionally, the application place of this type can be government solar street lighting projects and parking lot lighting. In fact, we did the projects in the USA, Australia, Dubai, and Spain.

• Price: $50-$500
• Lighting time:  8/10
• Lighting Span: 8/10
• Brightness:      8/10

These lamps are also used in high-quality solar lighting systems. Regardless of cost, it is still similar to integrated solar streetlights in terms of brightness, lighting duration, and lifespan. As a matter of fact, our customers in Europe and North America also prefer this kind of solar light design.

How to Customize the Design of Solar-LED Street Lights

So, how do we design and customize Solar-LED Street Lights? If you want to know the answer, read the following:

The picture above is a sample of a solar street light project we made according to customer needs in Texas, USA. (Click here to see more of our custom solar light projects)

If it is a customized design solar street light, firstly, we will consider the installation location. For example, in small roads or communities with little traffic, the requirements for lighting time and brightness do not need to be too high. The main road with large traffic flow requires strict lighting brightness and lighting time (To learn how to improve the lighting time of solar street lights, click here).

Secondly, we will determine the lumen value of the LED light according to the height and brightness requirements of the street light pole. Note that this is in lumens, not watts. Because the direct parameter that determines brightness is lumen value, not wattage. And we will use LEDs with high lumen efficiency as much as possible to save the cost of solar panels and batteries. If the project requires, we will provide the Dialux Simulation (To view more of our lighting design drawing service, click here).

In the third step, we will determine the size of the solar panel and battery according to the power and lighting time of the led street light. The battery generally uses a lithium battery, which is small in size and light in weight. Lithium batteries and solar panels are also the two most expensive components of solar lamps.
