A brief introduction to the current situation of rural solar street lights by Henan street light manufacturers.
1. The color of rural solar street lights is dim.
Many unscrupulous businesses in the market, in pursuit of profit, falsely report the configuration of solar street lights purchased by contractors, using inferior products to replace good ones, reducing the output power of photovoltaic panels and battery chargers. This results in the actual lighting effect of solar street lights being less than ideal and the color being dim. Additionally, the common LED processing chips used have high light loss and low lumen values, leading to even dimmer colors.
2. Short application cycle; many rural solar street lights have already stopped lighting.
Some manufacturers use batteries with a low cycle count, resulting in a short application cycle for rural solar street lights. Moreover, the normal lifespan of batteries is around five years. If areas that installed solar street lights five years ago do not have project funds to replace the batteries, then the solar street lights will stop working.
3. High theft rate of solar batteries.
In previous years, rural solar street lights mostly used gel batteries buried underground, which had a high second-hand recycling price and were easy to steal. Currently, lithium-ion batteries are used, installed at the top of lamp poles, making theft more difficult since gel batteries have a higher theft rate compared to lithium-ion batteries.
Henan street light manufacturers: How to choose solar street lights.
1. Purchase according to the actual installation area.
Photovoltaic panels with high conversion rates and stable technical parameters are suitable for southern regions with more rainy days and relatively less sunlight; photovoltaic panels with lower conversion rates are more suitable for areas in the central and western regions with ample sunlight. Therefore, in areas with excellent sunlight conditions, there is no need to equip monocrystalline silicon panels for solar street lights, which can reduce installation costs to some extent.
2. Purchase according to working voltage standards.
Solar photovoltaic panels are arranged in series and parallel; series affects working voltage while parallel affects current. As the required voltage and current differ, the size of the solar photovoltaic panels will also vary.
The electricity stored in the battery is provided by the solar photovoltaic panel. For normal battery charging, it is necessary to ensure that the voltage of the solar photovoltaic panel is about 1.5 times that of the battery voltage. For example, to charge a 6V battery, an 8V-9V solar photovoltaic panel is needed; for a 12V battery, a 15V-18V solar photovoltaic panel is required.
3. Purchase according to required power.
The size of solar photovoltaic panels is also affected by their own power; the utilization coefficient power of photovoltaic panels is about 127WP/square meter. The larger the area, the greater the output power. Generally, the power of solar photovoltaic panels should be about 3-5 times that of lamp source output power; in areas with abundant sunlight and short lighting time, it should be around 3-4 times; conversely, it should be around 4-5 times.
