When considering adding solar technology to existing street lights, many individuals are motivated by factors such as cost savings, environmental impact, and the feasibility of retrofitting existing infrastructure to incorporate renewable energy solutions.

What is Hybrid Solar Street Lighting?

Hybrid Solar Street Lights is a groundbreaking solar lighting system that integrates high-charging capacity solar panels with a grid supply as a backup. These innovative lights are the first of their kind, featuring a battery storage system without the need for an inverter. They offer a modern alternative to traditional street lighting, such as high mast or pole-mounted lights.

Equipped with solar panels, these lights harness solar energy during the day, which is then stored in the battery for nighttime use. Additionally, the hybrid solar street lights are connected to the external power grid, serving as a backup power source. When battery power is low, the system seamlessly switches to grid power, ensuring a reliable and consistent light supply. This advanced technology is ideal for illuminating streets and highways at night without relying solely on grid electricity.

The system’s programmable settings allow the lights to shine as needed, enhancing their cost-effectiveness. The design includes prewiring, eliminating the need for intensive wiring work and further reducing setup costs. These lights utilize energy-efficient LED technology, providing bright illumination and capable of continuous operation for over four days.

Beyond lighting, the stored energy in the batteries allows these hybrid solar street lights to serve as emergency power sources. The heavy-duty battery and sturdy construction make them reliable backups during power outages caused by storms or other events. The hybrid solar street lights feature a battery with a 12.8-volt capacity, ensuring dependable performance.

The Benefit of AC-Solar Hybrid System Lights

Cost Savings

• Reduce Electricity Bills: By integrating solar power with grid electricity, AC-Solar hybrid systems significantly reduce electricity bills. The reliance on solar energy during peak sunlight hours minimizes the use of grid power, leading to substantial cost savings over time.

• Utilization of Existing Poles: AC-Solar hybrid systems can be mounted onto existing street light poles, eliminating the need to purchase new poles. This not only reduces upfront costs but also preserves the aesthetic and continuity of the street lighting layout.

• Minimal Wiring Requirements: Retrofitting existing poles with hybrid systems typically requires minimal wiring modifications. The existing wiring infrastructure can often be utilized, reducing the need for extensive rewiring or trenching. This streamlines the installation process and minimizes labor costs.

• Simplified Installation: By leveraging the original poles and wiring, the installation of AC-Solar hybrid systems becomes more straightforward and cost-effective. Installers can focus on integrating the solar panels, battery storage, and control systems into the existing infrastructure, reducing both time and expenses associated with new construction. (The premise is that the pole has the load-bearing capacity and the local wind is not strong, because the new street light increases the weight of the battery and controller)
• Reduced Disruption: Retrofitting with hybrid systems minimizes disruption to the surrounding area compared to installing new poles and wires. There’s no need for extensive excavation or disruption to the landscape, leading to lower associated costs and fewer inconveniences for residents and businesses.

By leveraging existing poles and wires, AC-Solar hybrid systems offer substantial cost savings in addition to their energy efficiency and sustainability benefits. This makes them an attractive option for municipalities, businesses, and communities looking to upgrade their street lighting infrastructure without incurring significant upfront expenses.

Environmental Impact

AC-Solar hybrid systems contribute to a lower carbon footprint by harnessing clean, renewable solar energy. This helps reduce greenhouse gas emissions and promotes environmental sustainability.

Retrofit Feasibility

These hybrid systems can be easily retrofitted to existing street lighting infrastructure, eliminating the need for complete replacements and making upgrades both practical and economical.

AC-Solar hybrid systems bring significant benefits to original wiring infrastructure when retrofitting existing street lights. These systems are designed to seamlessly integrate with current wiring, minimizing the need for extensive rewiring or modifications.

By using pre-existing wiring for the grid connection while adding solar panels and battery storage, the installation process becomes simpler and more cost-effective. This not only reduces labor costs but also shortens the installation time, allowing for a quicker transition to a more sustainable lighting solution.

Moreover, the hybrid system enhances the durability and efficiency of the original wires by reducing the overall load and wear, as the solar component shares the power supply burden with the grid.

Technical Guidance

With straightforward installation and minimal wiring requirements, AC-Solar hybrid systems offer a user-friendly solution for upgrading traditional street lights to incorporate solar power.

Regulatory Compliance

AC-Solar hybrid systems are designed to meet local regulations and standards for public lighting, ensuring compliance while benefiting from renewable energy sources.

Reliability and Performance

The combination of solar and grid power in hybrid systems ensures consistent and reliable lighting. Solar energy provides primary power, with the grid serving as a backup to maintain performance even during periods of low sunlight.

Investment and Return on Investment (ROI)

Long-term savings on energy costs and maintenance offset the initial investment in AC-Solar hybrid systems. Lower initial investment costs enhance the ROI compared to a solar system, the reduction in electricity bills, and the extended lifespan of LED lighting technology. Using a backup electrical power solution means that you can design a smaller battery. In this case, you will spend less money on the product itself.

Energy Independence and Reliability

These systems reduce dependency on the local power grid, providing a reliable lighting solution even during power outages. This independence is particularly beneficial in areas prone to grid failures.

It can ensure the normal operation of the lighting system in any weather, even on continuous rainy days when the charging efficiency of the solar panels is low. It has excellent performance in application scenarios that require normal lighting operation 365 days a year.

Project Planning

For communities, businesses, and municipalities planning lighting upgrades, AC-Solar hybrid systems offer a versatile and future-proof solution. They combine the benefits of solar energy with the reliability of grid power, making them ideal for sustainable development projects.
