solar street light has its particularity, it is necessary to ensure the stability and reliability of the system, solar street

1. Solar cell module The voltage of the solar cell module will decrease with the increase of temperature. Due to the influence of high temperature, the voltage loss of the battery module is about 2V, and the voltage drop of the diode on the charging process controller is 0.7V, so the working voltage is selected. for 18V components. Due to the particularity of solar street light, solar panels are generally installed on light poles. For street light poles, it is generally more than 5 meters and the center of gravity is high. Most of the solar panels are suspended, in order to enhance the whole set of equipment. To resist the wind, generally choose multiple solar panels to form the required component power. 2. The controller The controller is a key component that acts as a manager in the entire street light system. Its function is to manage the battery. A good controller should set various key parameter points according to the characteristics of the battery, such as the overcharge point of the battery. , over-discharge point, recovery connection point and SOC discharge control, etc. When choosing a street light controller, special attention should be paid to the parameters of the controller's recovery connection point. Since the battery has voltage self-recovery characteristics, when the battery is in an over-discharge state, the controller will cut off the load, and then the battery voltage will recover. If the point is not set properly, the lamps may flicker and the life of the battery and light source will be shortened. 3. When choosing a battery (group), it is necessary to consider the impact of the discharge rate on the battery capacity, the impact of temperature on the battery capacity, and the impact of the depth of discharge on the battery capacity. Therefore, a deep-cycle solar battery must be selected. When the battery is connected in parallel, it is necessary to consider the unbalanced effect of each single cell. Usually, the number of parallel groups should not exceed 4 groups. Fourth, the selection of light source The selection of light source is the most critical step for solar street light. At present, there are few light sources dedicated to solar street light. In order to reduce the loss of limited energy, the light source should be DC light source as much as possible. At present, the common light sources include DC energy-saving lamps, high-frequency induction lamps, low-pressure sodium lamps and LED light sources.
