How to control photovoltaic street lights？

With the maturity and continuous development of photovoltaic power generation technology, photovoltaic street lights have become commonplace in our lives. Energy-saving, environmentally friendly, safe, and reliable, they bring significant convenience to our lives and contribute significantly to environmental protection. However, for street lights that provide brightness and warmth at night, their lighting performance and duration are crucial.

When customers choose photovoltaic street lights, street light producers typically determine the required nighttime operating time, which can range from 8 to 10 hours. The manufacturer then uses a controller to set a fixed operating time based on the project’s illumination coefficient.

So, how long do photovoltaic street lights actually stay on? Why do they dim in the second half of the night, or even go completely off in some areas? And how is the operating time of photovoltaic street lights controlled? There are several modes for controlling the operating time of photovoltaic street lights.

1. Manual Mode

This mode controls the on/off of photovoltaic street lights using a button. Whether daytime or nighttime, it can be turned on whenever needed. This is often used for commissioning or home use. Home users prefer photovoltaic street lights that can be controlled by a switch, similar to mains-powered street lights. Therefore, photovoltaic street lights manufacturers have developed home photovoltaic street lights specifically designed for use in homes, with controllers that can automatically turn the lights on and off at any time.

2. Light Control Mode

This mode uses preset parameters to automatically turn the lights on when it’s too dark and off at daybreak. Many light-controlled photovoltaic street lights now also incorporate timer controls. While light intensity remains the only condition for turning the lights on, they can automatically turn off at a set time.

3. Timer Control Mode

Timer-controlled dimming is a common control method for photovoltaic street lights. The controller pre-sets the lighting duration, automatically turning the lights on at night and then off after the specified duration. This control method is relatively cost-effective, managing costs while extending the lifespan of photovoltaic street lights.

4. Smart Dimming Mode

This mode intelligently adjusts the light intensity based on the battery’s daytime charge and the lamp’s rated power. Suppose the remaining battery charge can only support full lamp operation for 5 hours, but actual demand requires 10 hours. The intelligent controller will adjust the lighting power, reducing power consumption to meet the required time, thereby extending the lighting duration.

Due to varying sunlight levels in different regions, the lighting duration naturally varies. Tianxiang photovoltaic street lights primarily offer light-controlled and intelligent dimming modes. (Even if rainy for two weeks, Tianxiang photovoltaic street lights can guarantee approximately 10 hours of light per night under normal circumstances.) The intelligent design makes it easy to turn the lights on and off, and the lighting duration can be adjusted based on the specific sunlight levels in different regions, facilitating energy conservation.
