All-in-One vs. Split-Style Solar Street Lights: What to Consider?

All-in-one and split-style solar street lights are the two primary categories in the solar street light segment. Cost, efficiency, and the like are some of the considerations when choosing between them. But what are the specifics behind these factors, and are there any other aspects that should be taken into account? 

This article will guide you through the evaluation process and help you make an informed decision.

All-in-One vs. Split-Style Solar Street Lights: What to Consider?

Below is a quick recap for the definitions of these two types of lights, in case you just stepped into this field and are not acquainted with them.

  • Split-Style Solar Street Lights: These lights feature separate units for the solar panel, light fixture, chargeable battery, and other electronic accessories—connected via wires.
  • All-in-One Solar Street Lights: They are the most recent lighting solutions that integrate multiple components into a single unit. These units typically include all the primary components that can be seen on traditional split solar street lights, as well as other modern advanced devices like motion sensors—all housed within a compact design.

Their Strengths and Weaknesses

These two types of solar street lights do not simply differ in their looks. Both of them hold some strengths and weaknesses against each other.

Split-style street lights generally possess enhanced flexibility and efficiency. This is because their configuration allows for optimal placement of the solar panel to capture as much as sunlight as possible, while the light fixture can be adjusted with a higher level of freedom for effective illumination. Since the battery is separated, the capacity can be upgraded with ease by switching to a large one or stacking another piece. However, such flexibility induces their principal weakness: unfriendly aesthetic appeal.

In contrast, the sleek, compact and elegant look is the sparkling strength of all-in-one street lights, positioning them as an ideal choice for projects seeking to attain a superior aesthetic quality. These lights are designed with the provision of high-quality components, representing the latest advancements in relevant industry segments. Although the components can provide improved performance in both electric and luminous efficiency, their lack of flexibility as compared to their split-style counterparts may not often yield optimal outputs.

As a whole, split-style solar street lights generally hold lower price points than their all-in-one counterparts. Breaking it down, this is not only shown through their material and manufacturing costs but also maintenance expenditures.

Which Type Is the Better Choice for Your Project?

It should be admitted that each of these two types of light offers its own distinct pros and cons. In practical use, you cannot pick all the advantages together to make a dream light. Instead, you should strive to find a comfortable balance by evaluating your particular project needs, the conditions of the climate at the installation site, and your operational plans, aside from the characteristics of these lights.⚠️💡

The Climate Conditions of the Site

In light of the fact that solar street lights operate based on the photovoltaic principle, it is crucial to conduct a comprehensive evaluation of the climate conditions for the site where these lights will be installed.

The climate conditions may involve solar irradiation, temperature variations, precipitation levels, wind speeds and others.

A place with abundant solar irradiation, e.g., Nigeria, contributes more flexibility for the choice in the power rate and size of the panel on solar street lights. But places with rich solar irradiation can sometimes also come with high temperatures, which impacts the efficiency of the panel.

Wind speeds are often an overlooked factor in the adoption of solar street lights. Unlike all-in-one lights, split-style lights, with their components separated, expose more areas to wind load, which in turn can easily result in the light tilting or falling-over while posing safety risks for the vehicles and passengers below. 

Lastly, the prevalence of precipitation, such as rain or snow, must also be taken into account. Make sure the solar street lights are equipped with adequate waterproofing and corrosion-resistant materials. This is crucial for maintaining their functionality and structural integrity in adverse weather conditions.

Local Supply Chains & Post-Sale Services

As the tide of globalization continues to surge forward, developers source the best products for their projects from around the globe. Local supply chains and post-sale services are suggested to get calculated into the cost in order to effectively assess ROI.

Due to the all-in-one design, in which all components are ‘packed’ into a housing, alternatives to faulty components are comparatively not easy to find in the market, given that they are ‘somewhat customized’ in terms of dimensions, electric parameters, etc. The supply chain consideration should be granted a high priority for projects located in a region where the local solar and correlated supply chains are not mature, and local logistics is unsatisfactory.

In comparison, split-style solar powered street lights win this round in regards to maintenance. Basically, as long as the key electric specs match, there are a wide selection of alternatives out there. Because of this enhanced flexibility, operators can also customize their lights post-installation whether for an upgrade or downgrade. More notably, this helps to drive down overall costs.

Thus, in this case, if aesthetic appeal is not your critical factor to consider or say it is comfortably acceptable to compromise on the aesthetics, going for split style solar street lights brings you more goods.


Evaluating the specs of the solar street lights themselves is essential for your procurement process. Here’s an in-depth guide for you if you are concerned about missing something.

But as these lights outperform traditional electronic lights especially in those remote areas where electricity infrastructure is away from satisfaction, it is pretty important to weigh up the considerations outlined in the previous section for an effective investment.
