As communities strive to create safer outdoor spaces for relaxation and recreation, one technology has emerged as the front-runner in delivering the best overall value when it comes to safety in public spaces at night: solar lights.

By capturing the sun’s free electricity, solar lighting fixtures offer numerous advantages over traditional mains powered lighting. In this article, we will explore why solar lights are the future of security in public spaces, examining some of the key benefits, safety enhancements, and potential for integration into smarter connected cities.


Outdoor Public spaces offer a fantastic opportunity for communities to partake in all sorts of community events, exercise, and outdoor activities, but after dark safety can quickly become a concern for residents and the local council who’s responsibility it is to plan these spaces. Properly illuminated areas deter criminal activities, promote safety, and enhance the overall quality of public spaces. However, traditional lighting methods have limitations in terms of energy consumption, cost, and environmental impact. Solar lighting is one of the best ways of providing an alternative solution that addresses these issues while offering a range of additional benefits.

The Importance of Safety in Public Spaces

Public outdoor spaces, such as parks, parking areas, and pathways, are essential for community gatherings, recreational activities, and daily commuting. Ensuring the safety of these spaces is crucial for the peace of mind of residents and visitors alike. Adequate lighting plays a vital role in deterring crime, reducing accidents, and fostering a sense of safety and security.

Traditional Lighting vs. Solar Lights

Traditional lighting systems are dependent on the electricity grid, which can result in high energy costs. Additionally, the installation of mains lighting can be more complex and requires extensive ground, work, cabling, trenching connection costs which can make it a very expensive proposal. In contrast, solar lights operate independently of the electrical grid, instead charging from renewable energy from the sun. This fundamental difference offers several advantages that make solar lights an attractive option to improve public safety in outdoor spaces.

Advantages of Solar Lights

Energy Efficiency

Solar lights transform sunlight into electricity through photovoltaic cells, which offer the most energy efficient option for outdoor lighting. This choice bypasses the carbon emissions and energy consumption associated with mains powered lights. The decision to use solar lights not only contributes to a more sustainable and greener environment, but it also represents the cutting edge of energy efficient design. This makes solar lights the optimal choice for those seeking to minimise the carbon footprint of their projects.

Cost Savings

Although solar lights might require a higher upfront investment compared to traditional lighting, they present substantial cost benefits over time, making them a financially smart choice. Plus, solar public lighting has no operating costs as they do not require electricity from the grid. Plus, they require minimal maintenance, resulting in reduced cost of ownership over their lifespan.

Environmentally Friendly

Solar lights boast a remarkably small carbon footprint, positioning them as a green alternative in the realm of lighting solutions. They harness the clean, renewable energy of the sun, sidestepping the need for electricity generated from fossil fuels. This inherent use of solar power means that they actively reduce greenhouse gas emissions, a key contributor to climate change.

But their environmental impact goes beyond their own operations. The carbon emissions offset by solar lights can help balance out emissions produced by other projects or elements within a development. For instance, if a construction project involves elements that do produce carbon emissions, the introduction of solar lighting can help to mitigate that impact, reducing the overall carbon footprint of the project.

This makes them not only an environmentally responsible choice, but also a great tool for landscape architects and local government planners to help their clients achieve their sustainability goals.

Easy Installation and Maintenance

Installing solar lights is very simple compared to traditional lighting systems. They do not require wiring, trenching, power connection or even an electrician present to install allowing for flexible placement by. Moreover, solar lights require minimal maintenance, with Green Frog Systems solar products only needing occasional cleaning of the solar panel and periodic battery inspection every 5-10 years (depending on the install locations and the battery type in your product)

*Worth Noting– cheaper solar lighting products can have a lifespan as short as 1 to 2 years at which time they require complete replacement as they are often not serviceable. This can significantly add to the cost of a project having to hire skilled labour and elevated work platforms for access to then replace and dispose of failed units. Talk about bad news for the environment!

Green frog systems will always recommend investing in a quality product that is durable enough to endure the environmental conditions and a quality build that will remain reliable in the long-term.

Enhanced Safety with Solar Lights

Solar lights enhance safety in public spaces through their bright illumination. Well-lit areas discourage criminal activities by increasing visibility and creating a sense of security. Furthermore, solar lights can be strategically placed in areas prone to accidents or criminal behaviour, further deterring potential wrongdoers.

Improved Accessibility

Public spaces should be accessible to everyone, including individuals with disabilities. Solar lights can be equipped with motion sensors, ensuring that areas are well-lit when people approach. This feature improves accessibility for visually impaired individuals, providing them with a safer and more inclusive environment.

Solar Lights and Crime Prevention

The presence of well-lit areas has been proven to reduce crime rates significantly. Solar lights contribute to crime prevention by illuminating public spaces and making them less attractive to potential criminals. With their independent power source and bright illumination, solar lights play a crucial role in creating safer communities.
