All-in-One Solar Street Light vs Split Solar Street Light

Over the last few years, solar street lights have emerged as a more favored option for roads, parking lots, neighborhoods, parks, campus, and commercial sites. Solar Street Lights can save energy consumption costs from grid electricity, ease installation, and ensure reliable street lighting.

There are two common types of solar street lighting systems to choose from: all-in-one solar street lights and split solar street lights. While they both share the common resource of solar energy, there are differences in their design, installation, performance, and optimal application.

Therefore, the question is whether it is better to have an all in one solar street light or a split solar street light?

The solution depends on the requirements of your project, the installation environment, the lighting needs and budget.

What Is an All-in-One Solar Street Light?

All in one solar street light combines most of the components into one compact unit. The components normally include the solar panel, LED light, lithium battery, controller, and other electrical components, and all of these components are housed together.

In the day, the solar panel harnesses sunlight to generate power, which is stored in the battery. The battery supplies power to the LED lighting system at night.

All in one solar street lights are relatively easy to install because of their integrated design, which means that there is no need for separate battery boxes, cables or external solar panels.

Key Features of All-in-One Solar Street Lights

• Integrated solar panel and LED light
• Built-in lithium battery
• Compact and modern design
• Simple installation
• Minimal external wiring
• Low maintenance requirements
• Suitable for many off-grid applications

Given the size of all-in-one solar street lights, they are particularly sought-after for residential streets, parks, pathways, parking spaces, and small commercial solar projects.

What Is a Split Solar Street Light?

Split solar street light is based on the principle of separating the components of a solar street light. The solar panel, LED lamp, battery and controller are mounted independently and are connected by cables.

The solar panel can be located away from the LED lamp, unlike an all in one system. This allows for more flexibility in determining where and at what angle to install the solar energy collection system.

Solar street lights are commonly used in split applications where the road, highway, large parking lot, industrial lighting, or lighting performance or battery size is a higher requirement.

Key Features of Split Solar Street Lights

• Separate solar panel and LED lamp
• Flexible component placement
• Larger battery capacity options
• Easier customization
• Suitable for high-power lighting
• Better flexibility for challenging installation environments

All-in-One vs Split Solar Street Light: Key Differences

The biggest difference between these two systems is their component configuration.

Understanding these differences can help project owners choose the most appropriate solar lighting solution.

Installation: Which Solar Street Light Is Easier?

As far as installation is concerned, all-in-1 solar street lights typically enjoy the benefit.

The solar panel, battery, controller and LED are all contained in a single package, so the installation will typically consist of attaching the light to an appropriate pole, connecting the components.

This can result in substantial installations time and manpower savings.

Additional installation is needed for split solar street lights. The solar panel must be attached separately and the battery and controller can also be housed in a separate enclosure or mounted elsewhere. Proper installation and protection of cables is also required.

All-in-one solar street lights can be an ideal solution for projects with numerous lighting spots, like residential streets or parking lots.

Performance and Solar Energy Collection

Split solar street lights have more flexibility in collecting solar energy.

The solar panel is separated from the LED lamp, thus installer can mount it at the optimal angle and direction based on the local sunlight conditions. This can be useful for areas where the lamp installation location is not in the ideal sun position.

In all-in-one solar street lights, the solar panel is directly mounted on the lighting unit, resulting in a more compact design. Thus, panel orientation is more related with the fixture orientation as a whole.

For locations with challenging sunlight conditions, a split system may provide greater design flexibility.

Battery Capacity and Runtime

Another key factor to look at is the battery capacity of all-in-one solar street lights and split solar street lights.

Most all in one lamps employ a small efficient built-in lithium battery. They can meet a variety of normal demands — such as lighting moderate loads — in many cases.

The advantage of split solar street lights is that they can use bigger batteries because the batteries don't have to fit in the lamp housing. This makes them more appropriate for applications where they must run for longer periods of time at night, or they must be brighter, or they need to power up for multiple days in a row if the sun is in limited supply.

Split solar lighting systems can provide more flexibility in batteries for example on highways, industrial roads and large public infrastructure projects.

Maintenance and Reliability

All in one solar street lights have less external cables and connections. This can minimise potential failure points due to damaged cable, or water ingress or loose connections.

Their design also ensures they are easy to maintain on a regular basis.

When an internal part fails however, depending on product design, the integrated structure can make it more difficult to replace parts.

Split solar street lights allow individual parts to be easily accessed and replaced. Technicians can check and replace the solar panel, battery, controller, and LED lamp should any one of them malfunction, without having to replace the entire system.

Hence, all-in-one systems are simple whereas split systems are flexible and serviceable.

Cost Considerations

The total cost of a solar street lighting project includes more than the purchase price of the light itself.

You should consider:

• Equipment cost
• Pole and mounting costs
• Installation labor
• Wiring
• Transportation
• Maintenance
• Battery replacement
• Long-term energy savings

All in one solar street lights will help to cut installation cost as it minimizes the need for various components and wiring.

Split solar street lights can be more expensive to install, but can be more cost-effective in larger, or more complex projects thanks to their customizable design.

So, the most affordable product may not be the most cost-effective. A more sensible way is to consider the total cost of ownership (TCO).

Which Is Better for Different Applications?

There is no universal winner between all-in-one and split solar street lights.

Choose All-in-One Solar Street Lights If:

• You need fast installation
• The project has many lighting points
• Installation space is limited
• You prefer a clean and compact appearance
• Lighting requirements are moderate
• You want to minimize external wiring
• You are installing lights in parks, residential areas, pathways, or parking lots

Choose Split Solar Street Lights If:

• You need higher lighting power
• Large battery capacity is required
• Solar panel positioning needs to be customized
• The project is located in an area with difficult sunlight conditions
• You need flexible component selection
• The application involves highways, industrial roads, or large public infrastructure

How to Choose the Right Solar Street Light

Project owners need to consider some technical aspects before buying a solar street light system.

In the first step calculate the illumination level and the power of LED lighting. Pedestrian lighting has different characteristics than highway lighting.

Secondly, assess the solar radiation and the average number of sunshine hours in the area. In areas that get cloudy in the seasons, bigger solar panels and batteries might be needed.

Third, take into account the autonomy days needed. In case the light has to work for a few rainy or cloudy days, a higher energy storage capacity might be needed.

Last, but not least, think of the quality of the battery, LED chips, solar panel, controller, housing and waterproof protection. A solar street lighting should be designed to withstand long-term outdoor exposure.

Conclusion: All-in-One or Split Solar Street Light?

The decision to use an all-in-one solar street light or split solar street light is largely a project-based choice, and not just price.

When simplicity, compactness, ease of installation and low maintenance are desired, all-in-one solar street lights are the solution. An ideal option for residential streets, parks, pathways, parking lots, and a wide variety of small to medium outdoor lighting applications.

Children's street lights are suited to projects with a higher demand for power, larger batteries, flexible positioning of the solar panels and customized set-ups. They are especially suitable for highways, industrial complexes, big roads, and challenging off-grid situations.

To get the best results, the easiest thing to do is to compare solar panel capacity, battery chemistry & battery capacity, LED efficiency, lighting output, operating time, IP rating, warranty, and total project cost, which includes the initial price of the panel, not just the price of the LED.

The advantages of solar street lights lie in their ability to cope with a variety of weather conditions, such as rain, snow, and extreme heat, while functioning effectively in diverse environments, including urban, suburban, and rural areas.The benefits of solar street lights are that they can adapt to various weather conditions, such as rain, snow, and extreme temperature, and are more cost-effective and energy-efficient than traditional street lights.
