As a manufacturer that has been deeply involved in the field of solar lighting, street lights are what we deal with most every day. But street lights are not just a pole and a lamp standing on the roadside, there are a lot of interesting knowledge behind them. Today, let's talk about the details of solar street lights that you may not have noticed from the perspective of manufacturers.
1. The "super long standby" secret of solar street lights
Many people think that solar street lights rely on "weather for food", but in fact, its intelligent control system is the hero behind the scenes. On sunny days, solar panels charge and batteries store energy; on rainy days, the system automatically adjusts the brightness or switches to energy-saving mode to ensure that it will not "strike" for 5-7 consecutive days. Today's lithium battery technology can even allow street lights to last longer in extreme weather - of course, we recommend that you don't always test its limits.
2. Why are some street lights "brighter at night"?
Traditional street lights run at full power as soon as it gets dark, while solar street lights are more "smart". Through human body sensing or traffic monitoring, it can maintain low brightness when no one is around, and instantly brighten when it senses movement. This "on-demand allocation" design saves electricity and prolongs life. Manufacturers call it "not wasting every ray of sunlight."
3. The "hidden skills" of street light poles
Do you think that light poles are just for support? Today'ssolar street light poles may be "multi-functional warriors": integrated Wi-Fi, surveillance cameras, environmental monitoring sensors, and even electric vehicle charging piles. As a manufacturer, the most common customer request we hear is: "Can you add another XX function?" - Of course, the premise is that the budget and the load-bearing capacity of the pole body allow.
4. Will it "turn off" in winter?
Customers in the north are always worried about winter efficiency issues. In fact, solar panels work more efficiently at low temperatures (semiconductor characteristics are afraid of heat but not cold), but snow coverage will affect charging. Our solution is: increase the inclination design to let the snow slide naturally, or use double-sided power generation panels - even the light reflected by the snow on the ground is not spared.
5. Installation Mistakes That Manufacturers Are Most bothered By
In after-sales cases, 80% of the problems are caused by installation:
The solar panel faces north (it should be due south!);
There are big trees next to it and they still complain about insufficient charging (shadows are the natural enemy of photovoltaics);
The street lights are installed under the eaves to "protect against rain" (but they also protect against sunlight)...
So, the first page of our current product manuals is printed with the bold "Three Principles of Installation Location": No obstruction, no obstruction, and no obstruction.
6. The economic account behind the environmental account
Customers often ask: "How much more expensive is solar street light than city electricity?" If you only count the initial cost, it is indeed higher. But after counting the 5-year electricity bill, cable laying fee, and later maintenance fee, solar street lights are more cost-effective. We have a project that replaced 200 traditional street lights, saving more than 30,000 yuan in local electricity bills per month - this does not include the "disturbing cost" of digging roads and repairing cables in the middle of the night.
As a manufacturer, street lights in our eyes have never been cold industrial products. From windproof level testing when selecting materials to customizing color temperature for different regions (for example, white light is suitable for mosquito repellent in tropical regions), every detail is answering a question: how to make technology more considerate to life.
Next time you pass by a solar street light at night, you might as well look up - what lights you up is not only the electricity converted from sunlight, but also the wisdom of an entire industrial chain.
