Currently, many old urban and rural streetlights are aging and in need of upgrading, with solar streetlights being the mainstream trend. The following are specific solutions and considerations from Tianxiang, an excellent outdoor lighting manufacturer with over a decade of experience.
Retrofit Plan
Light Source Replacement: Replace traditional high-pressure sodium lamps with LEDs, which can nearly double the brightness.
Controller Installation: A single-lamp controller enables 0-10V dimming and remote monitoring.
Solar System Retrofit: Use an integrated solar streetlight, integrating solar panels, batteries, LED lamp heads, and controllers for an independent power supply.
Precautions
1. Evaluate the Reusability of the Old Lamps
Retain the original lamp poles (check for load-bearing capacity and stability; no need to re-cast the foundation) and the lamp housing (if the LED light source is intact, it can continue to be used; if the old sodium lamp is replaced with an energy-saving LED light source). Remove the original mains power supply lines and distribution box to reduce resource waste.
2. Installing Core Solar Components
Add solar panels of appropriate power (monocrystalline or polycrystalline panels, depending on local sunlight conditions, with angle adjustment brackets) to the top of the pole. Install energy storage batteries (lithium or gel batteries, with a capacity tailored to the lighting duration requirements) and a smart controller (to manage charging and discharging, light control, and timer functions) at the base of the pole or in a reserved bay.
3. Simple Wiring and Debugging
Connect the solar panels, batteries, controller, and lighting fixtures according to the instructions (mostly standardized connectors, eliminating the need for complex wiring). Debug controller parameters (e.g., set the lights to automatically turn on at dusk and off at dawn, or adjust the brightness mode) to ensure proper daytime energy storage and stable nighttime lighting.
4. Post-Installation Inspection and Maintenance
After installation, inspect the mounting of all components (especially the wind resistance of the solar panels) and regularly clean the surface of the solar panels. This eliminates the need for utility bills and only requires maintenance on the batteries and controller, significantly reducing long-term costs. This system is suitable for renovations in rural roads and older residential areas.
This renovation can save thousands of yuan in electricity bills annually and reduce carbon emissions. While initial investment in solar panels, batteries, and other components is required, solar street lights offer long-term economic benefits. Converting 220V AC street lights to solar ones is feasible, but it requires comprehensive consideration of various factors and adherence to safety regulations. Consulting with professionals is essential. Tianxiang, an outdoor lighting manufacturer, is happy to provide you with conversion solutions.
