The solar cell made by the solar photovoltaic effect principle receives solar radiant energy and converts it into electric energy output. It is stored in the battery through the charge and discharge controller. At night, the illuminance gradually decreases to about 101ux, and the solar panel open circuit voltage is 4.5V. Left and right, the charge and discharge controller detects this voltage value and then operates, and the battery discharges to the lamp cap. After the battery is discharged for 8.5 hours, the charge and discharge controller operates and the battery discharge ends. The main function of the charge and discharge controller is to protect the battery.
The battery design capacity calculation is simpler than the peak wattage of the solar module.
According to the above calculation, the daily power consumption of the load is 12. 2AH. In the case of full battery, you can work 7 rainy days in a row, plus the work of the first night, battery capacity:
12. 2 × (7 + 1) = 97. 6 (AH), the choice of two 12V100AH ​​batteries can meet the requirements.
Solar LED lighting system controller
The main function of the solar charge and discharge controller is to protect the battery. The basic functions must have overcharge protection, over discharge protection, light control, time control and anti-reverse connection.
The general parameters of the battery over-charge and over-discharge protection voltage are shown in Table 1. When the battery voltage reaches the set value, the state of the circuit is changed.
At present, the initial investment in solar LED lighting is still a major problem that plagues us. However, the solar cell's luminous efficiency is gradually increasing, and the price will gradually decrease. Similarly, the LED light efficiency in the market is rapidly increasing, while the price is decreasing. Compared with the renewable, clean and pollution-free solar energy and the environmental protection and energy saving of LED, conventional fossil energy is becoming more and more tense, and it will cause increasingly serious pollution to the environment after use. Therefore, solar LED lighting as an emerging outdoor lighting, showing us will be endless vitality and broad prospects.
