What is Solar Traffic Lighting 

As traffic flow continues to grow, the need for efficient and reliable traffic signal systems has never been greater. Solar traffic lighting provides a practical solution, using solar energy through photovoltaic (PV) panels to convert sunlight into electricity and operate independently of the main power grid. 

These systems incorporate AGM batteries and charge controllers to store and regulate energy ensuring consistent performance in permanent, temporary, and remote locations. As a result, they offer a cost effective, low-maintenance and environmentally responsible alternative for  modern traffic controls, while continuing to operate during power outages. 

Unlike mains powered systems, solar traffic lighting relies on stored renewable energy rather than grid electricity, helping to reduce both operational costs and environmental impact across urban and rural environments.

How Solar Traffic Lighting Works

Solar traffic lighting systems operate through a simple and efficient process. Photovoltaic panels capture solar energy and convert it into electricity, which is then stored in batteries via a charge controller. This stored energy powers LED signals, ensuring consistent visibility both day and night.

Designed for reliability, these systems continue to function in low-light conditions and during periods of limited sunlight, making them well-suited to the UK climate. Their primary purpose is to support safe and effective traffic management by ensuring that signals and signage remain clearly visible in all weather conditions.

Where Is Solar Traffic Lighting Used?

Solar traffic lighting is widely used across a range of applications where access to mains power is limited, costly, or impractical. Common use cases include:

  • School crossings and pedestrian areas – particularly with Belisha beacons

  • Temporary roadworks and construction sites

  • Rural and off-grid road networks

  • Urban sustainability and energy-saving initiatives

These applications benefit from quick installation, reduced infrastructure requirements, and reliable performance without ongoing electricity costs, making them ideal for both temporary and permanent traffic management solutions.

Types of Solar Traffic Lighting

At Portland Traffic, solar lighting solutions are designed to suit different applications, from pedestrian crossings to illuminated signage.

Zebstar Solar
Zebstar Solar is a fully engineered, solar-powered solution designed for off-grid Belisha beacons. It is ideal for locations where access to mains power is difficult or costly. The system features a 93-watt cylindrical solar panel, optimised to perform efficiently in low-angle winter sunlight, and is paired with an AGM battery to ensure reliable, year-round operation.

Solar Hydra
Solar Hydra is designed to illuminate traffic signs up to 750 mm in accordance with E2 UE3 standards. It delivers reliable, consistent performance using a 93-watt cylindrical solar panel that captures low-angle sunlight while simplifying installation and reducing the risk of setup errors.

Both systems use battery storage to ensure continuous operation, bridging the gap between energy generation and usage while maintaining visibility at all times.

Benefits of Solar Traffic Lighting

Solar-powered traffic lighting offers several key advantages:

  • Cost efficiency – eliminates the need for trenching, cabling, and ongoing electricity costs

  • Environmental sustainability – uses solar energy to reduce carbon emissions

  • Energy independence – operates without reliance on the mains power grid

  • Easy installation – quicker to deploy with minimal disruption

  • Improved safety – ensures consistent visibility in all conditions

  • Low maintenance – designed for long-term, reliable performance

Solar vs Mains-Powered Traffic Lighting

Choosing between solar and mains-powered systems depends on the project requirements.

Solar traffic lighting:

  • No ongoing electricity costs

  • Faster, less invasive installation

  • Ideal for remote or temporary locations

  • Supports sustainability targets

Mains-powered lighting:

  • Continuous and stable power supply

  • Suitable for high-demand, permanent infrastructure

  • Requires cabling and professional installation

  • Ongoing energy and maintenance costs

For many applications, particularly in off-grid or cost-sensitive environments, solar solutions offer a more flexible and efficient alternative.

Why Choose Solar Solutions Over Mains-Powered Systems 

Solar traffic lighting is particularly effective in environments such as school crossings, rural roads, and temporary works, where quick deployment and reliability are essential. By removing the need for mains infrastructure, these systems help reduce installation time, lower costs, and support more sustainable road safety solutions.

If you’re looking to reduce installation costs or deploy reliable lighting in remote or off-grid locations, solar traffic lighting offers a practical solution.
