Many people know that when traditional street lights cover rural areas, it is extremely difficult to achieve "power supply to every village" through large-scale construction of power grid lines. The challenges of long power supply lines, large power supply radii, and low power supply voltages make electrification projects nearly impossible to advance.Zhengzhou Solar Street LightThere is no need for power generation, so solar street lights in new rural areas have become essential lighting for these rural areas.
Due to the vast area of rural areas, low population density, low electricity consumption, and low energy density, renewable energy sources such as photovoltaics, wind energy, and biogas are naturally very suitable for application in rural environments. It can be said that Zhengzhou solar street lights in new rural areas provide a more independent option for farmers in remote areas. For these areas, new rural solar street lights can be installed anytime and anywhere, are easy to install, and can be used within a few days or months.
Installing solar street lights in new rural areas is both quick and convenient. If electricity can only be used after the national power grid is laid out, when will these remote villages be able to use electricity? It depends on the local long-term planning and budget for long-distance transmission lines, and even on the overall national power planning; farmers in these areas may despairingly wait for years, even decades. It is well known that the working principle of Zhengzhou solar street lights is to receive sunlight during the day, convert it into electrical energy stored in batteries, and discharge it at night to power LED lights. Therefore, whether it supports rainy days is a very important reference factor when configuring solar street lights.
Rainy days refer to continuous overcast and rainy days,Zhengzhou Solar Street Lightwhen they can still light up normally with little or no solar energy replenishment. Not only on these days can solar street lights not function properly. During rainy days, we need customer support. Typically, the default number of days is 3; since the configuration of integrated solar street lights is relatively fixed and determined after multiple tests, it is usually higher by default during rainy days. The number of rainy days determines the size of photovoltaic components and batteries and is an important reference parameter for configuring solar street lights. Therefore, when determining rainy days, it should be based on local conditions. If your area has many consecutive overcast and rainy days, you should appropriately increase by 1-2 days to avoid abnormal working conditions.
What are the purchasing tips for Zhengzhou solar street lights?
1. Consider the system lifespan of the solar street light: There are various factors that affect the lifespan of solar street light products, but generally include LED constant current driving devices and batteries. Only after the lifespan of these two factors has passed will such solar street light products have a longer lifespan. When choosing an LED constant current driver, attention should be paid to the brand and quality of the electrolytic capacitors in the LED constant current source. Of course, LED digital constant current source driving technology does not require electrolytic capacitors; the main materials are semiconductors. Additionally, when purchasing batteries for solar street lights, attention should be paid to the material and model of the battery.
2. Consider the brightness of the entire lamp: Solar street lights do not mean that a higher power source is better. Many manufacturers exaggerate power or purchase low-lumen lamp beads to reduce costs. In fact, to achieve the same brightness, a lower power source is better.
3. We should consider sunny days to withstand long rainy days: Currently, most solar street lights can only withstand 3-7 consecutive rainy days, but some companies are making continuous technological efforts to make their solar street light products withstand bright days during long rainy periods.
