What Are SOLTECH Products?

SOLTECH products are solar-powered traffic safety systems designed to improve visibility, guide driver behaviour and reduce risk in high-traffic and high-exposure environments. They are used to manage vehicle movement, highlight hazards and support safer pedestrian interaction across a wide range of commercial and public sites.

Each system is developed to respond to specific operational challenges, whether that involves reinforcing speed compliance, increasing awareness in low-visibility conditions or providing clear guidance in complex traffic areas. Solutions are available as standard configurations or can be engineered to suit site-specific requirements and performance criteria.

This flexibility allows SOLTECH systems to be applied across council, infrastructure and commercial projects where consistent performance, adaptability and long-term reliability are essential.

Solar Radar Speed Signs

Radar speed signs offer effective visual enforcement of designated speed limits, typically installed in areas where speeding vehicles pose a risk to pedestrians. The Solar Radar Speed Limit Sign uses ultra-bright, high-quality, long-life LED technology to dynamically display the speed limit. Its low power consumption is efficiently supported by solar energy. A Bluetooth app (Android) allows users to control the full dot-matrix display, adjust the posted speed limit between 0 and 99 km/h and perform system analysis. Once set, the radar detects oncoming vehicles and displays their speed. Available in fixed, relocatable or portable versions.

Solar Traffic Light System

The Solar Traffic Light System enhances pedestrian safety by managing vehicle traffic at pedestrian crossings and indicating when it is safe or unsafe to cross. This system operates similarly to standard pedestrian crossing and traffic light systems but without the need for complex wiring or trenching to run power. It is entirely powered by a high-quality solar powerbank mounted on the same post as the pedestrian sign and activation button or PIR sensor.

Solar-Enhanced Road Signs

Enhancing road signs with solar LEDs is a straightforward and effective method to boost message visibility and improve safety for both pedestrians and vehicles. This technology uses a pair of synchronised, ultra-bright, reflective-backed LEDs that operate day and night, visible from up to 1,000 metres away. A solar panel connected to a high-quality LiFePO4 battery provides up to 72 hours of LED operation on a single full charge.

Solar Stop Signs

Solar LED Stop Signs capture drivers’ attention with integrated LEDs that animate upon activation or operate continuously 24/7. They are designed for potential collision points to visually reinforce the stop message. When activated by vehicle or pedestrian interaction, the text “STOP” animates. Optional high-intensity, animated edge-lit LEDs further emphasise the message in high-risk areas.

Solar Lighting Designs provides engineered solar lighting and traffic safety systems that eliminate trenching, reduce installation costs and deliver reliable off-grid performance. As a manufacturer, supplier and installer, the company delivers complete solutions from design through to installation and support. Its systems include solar-powered traffic signs and fully customised solutions built for Australian conditions and long-term use.

We offer a comprehensive range of solar-powered road safety products that are designed to enhance safety and traffic management in a variety of settings. These products include solar radar speed signs, which display real-time vehicle speeds to help reduce speeding and encourage safer driving behaviour. Our solar radar speed signs are ideal for use on highways, school zones or residential areas where it is critical to monitor and manage speed. Additionally, we provide solar-enhanced road signs that offer improved visibility compared to traditional road signs. These signs are perfect for indicating important traffic information, such as hazard warnings, road closures or directional signage.

Other essential products in our range include solar over-height warning systems, which alert drivers to low-clearance bridges or structures, reducing the risk of accidents in commercial areas, industrial zones or construction sites. Our solar high water warning systems are particularly beneficial for flood-prone areas, warning drivers of high water levels and preventing them from driving through flooded regions. We also offer solar variable speed limit signs, which automatically adjust speed limits based on traffic conditions or weather, improving safety and ensuring that speed limits are always up to date. Lastly, our solar road markers help clearly define lanes, intersections or parking areas, especially at night or in low-visibility conditions. All of these solar-powered traffic and safety products are energy-efficient, cost-effective and environmentally friendly, making them ideal for areas with limited or no access to electrical infrastructure.

Solar-powered road signs significantly improve road safety by providing constant illumination and clear visibility of important road information. Unlike traditional signs, solar-powered signs are brighter and more visible, ensuring that vital information such as speed limits, traffic hazards and road changes is clearly visible to drivers at all times. This is particularly important in areas where visibility may be compromised due to poor weather conditions, night-time driving or heavy traffic. The increased visibility of solar road signs helps drivers make safer decisions and reduces the likelihood of accidents.

Another way solar-powered road signs enhance safety is by providing real-time information. For example, solar-powered variable speed limit signs can adjust the speed limits based on current traffic conditions, weather or even the time of day. This dynamic approach to traffic management ensures that drivers are always informed of the safest and most appropriate speeds for the conditions at hand. Furthermore, solar-powered road signs operate continuously, day and night, without the need for an external power source. This ensures that important messages are always visible, even in remote areas where electricity may not be available. By improving road visibility and driver awareness, solar-powered traffic signs contribute to safer driving conditions for both motorists and pedestrians.

Yes, many of our solar-powered road safety products can be fully custom manufactured to meet the unique needs of your project or location. Whether you require custom signage for specific traffic management purposes or need special features like flashing lights, dynamic speed limits or integrated lighting, we can design a solution tailored to your requirements. We understand that every road, intersection and traffic scenario is different, and as such, we offer a range of customisation options to ensure that our solar-powered traffic systems fit perfectly with your project needs.

For example, solar radar speed signs can be customised with specific speed limits, colours and messages tailored to your location. Similarly, our solar-enhanced road signs can be designed with different graphics, colours and symbols to suit the requirements of a particular road or commercial zone. We can also provide solar road markers that can be customised to enhance night visibility in high-risk areas such as curves, intersections or pedestrian crossings. Additionally, we can integrate solar-powered road signs with existing CCTV systems or smart traffic management solutions to provide real-time monitoring and data collection. Our team works closely with local councils, construction companies and commercial clients to ensure that each solar-powered road safety product is optimally designed for the environment and the specific safety needs of the area.

There are numerous benefits to using solar-powered traffic signs, which make them an excellent choice for public safety and traffic management. One of the most significant advantages is their energy efficiency. Solar-powered road signs rely on renewable energy, meaning they do not require electricity from the grid. This reduces energy consumption and cuts down on electricity costs, providing a cost-effective solution for municipalities, construction sites and commercial properties. They are also eco-friendly, as they help reduce the carbon footprint by using clean, renewable energy from the sun.

Another major benefit is the low maintenance required for solar-powered traffic signs. Unlike traditional signs, which may need regular wiring, repairs or power supply adjustments, solar road signs are designed for durability and can operate without significant upkeep. The solar panels that power the signs are designed to last for many years, typically 10-15 years, with minimal cleaning needed. Additionally, since they operate independently of the power grid, solar-powered road signs can be installed anywhere, even in remote locations, where traditional power infrastructure would be costly or difficult to implement. These signs provide continuous operation regardless of external power availability, ensuring they are always operational and reliable.

Yes, solar-powered road and safety products are specifically designed for remote locations, where access to mains power is either limited or unavailable. These off-grid solutions offer a reliable and self-sufficient way to install traffic signs, speed signs and other safety products without the need for electrical wiring or connections. Since solar-powered traffic systems rely on solar panels to capture energy from the sun, they operate completely autonomously, providing an ideal solution for areas such as rural highways, construction sites, remote towns or campsites, where power supply is limited or non-existent.

Installing solar traffic products in these areas is both cost-effective and environmentally friendly, as it eliminates the need for expensive infrastructure and ongoing electricity costs. The solar panels can charge during the day, and the lights or signs will operate at night, providing reliable illumination and alerts regardless of access to mains power. Whether you need solar road signs in a flood-prone area, solar speed signs along a remote highway or solar warning systems in a construction zone, these products offer a perfect solution for remote or off-grid locations. They are designed to withstand harsh weather conditions and continue functioning in even the most isolated environments, making them a reliable choice for all your road safety needs.

Installation is typically faster than traditional lighting because solar systems do not require trenching or electrical connections. Standard applications such as solar road safety signs can often be installed quickly with minimal disruption, while larger or custom systems may take longer depending on scope. The self-contained design allows for efficient deployment across most sites.

Solar bollard lights require minimal maintenance due to their self-contained design and durable components. Basic upkeep usually involves occasional cleaning of the solar panel and periodic inspections to ensure performance. Like other solar-powered road signs, they operate independently of the grid, reducing ongoing costs and servicing requirements.

Solar Lighting Designs provides a 2-year warranty covering faulty workmanship or component failure not caused by external factors. Support is available across design, installation and ongoing system performance. This applies across all systems, including solar LED traffic signs and customised installations.

Solar Lighting Designs services projects across Australia, with locations in Brisbane, Melbourne, Sydney and Perth.
