Can I retrofit solar lighting to my existing street lighting columns?

In recent years, solar street lighting has become an increasingly attractive solution in the UK, offering numerous benefits such as cost savings on trenching, quick fixes for temporary lighting applications, and energy savings. Solar technology ticks many sustainability boxes. When combined with the reuse of existing street lighting infrastructure, it aligns with the principles of the circular economy, helping to preserve natural resources and enhance cost-effectiveness.  

However, while retrofitting solar lighting to existing columns is a viable option for many projects, it’s essential to assess it’s suitability based on two critical questions: 

1. Will the existing column withstand the extra weight of the solar system? 

A solar lighting system adds additional weight and wind loading to the column. Therefore it’s crucial to ensure that your current column is designed, manufactured and rated to withstand these extra demands. If your existing column is robust enough to accommodate the increased weight and wind forces, retrofitting solar lighting is feasible. However, if the column lacks the necessary strength, it will need to be replaced to support a solar luminaire and panels.

2. Is the existing column in a shadow-free area with direct sunlight? 

Solar street lighting relies entirely on sunlight to function optimally. Therefore, the solar panel must be installed in a location free from shadows, with direct exposure to sunlight and with no obstructions, such as trees. If your existing column is situated in such an area, retrofitting solar lighting is viable. However, if the column is shaded, the solar lighting system may perform inefficiently or fail to operate altogether. In such cases, alternatives to solar should be considered. 

If you answered “yes” to both questions, retrofitting solar lighting to your existing column is indeed possible. We offer easy-to-install solar street light retrofit kits with short lead times, designed to mount onto existing columns offering an environmentally friendly, off-grid solution to replace mains-powered streetlighting.

If you answered ‘no’ to one or both of the above questions, we recommend reconsidering the use of your current column for solar retrofitting. Our Solar Lighting Buying Guide provides valuable guidance, listing all the essential information to consider from any solar lighting manufacturer or distributor.
