Since the input energy of the solar photovoltaic power generation system is not stable enough, it is generally necessary to configure the battery system to work, and solar lamps are no exception, and the battery must be configured to work. Generally, there are lead-acid batteries, Ni-Cd batteries, and Ni-H batteries. Their capacity selection directly affects the reliability of the system and the price of the system. The selection of battery capacity generally follows the following principles: first, on the premise that it can meet the night lighting, the energy of the solar cell components during the day should be stored as much as possible, and at the same time, it should be able to store the electrical energy that meets the continuous cloudy and rainy night lighting needs. If the capacity of the battery is too small, it cannot meet the needs of night lighting or continuous use; if the capacity of the battery is too large, and the battery board cannot provide enough charging current, the battery is often in a state of power deficit, which affects the life of the battery and causes waste at the same time.
Solar lighting products have the advantages of energy saving and environmental protection. Of course, the load should be energy-saving and have a long life. We generally use LED lamps, 12V DC energy-saving lamps and low-pressure sodium lamps.
Most lawn lamps use LED as the light source, the LED has a long life, can reach more than 100,000 hours, and has a low operating voltage, which is very suitable for use in solar lawn lamps.
Garden lights generally use LED lights or 12V DC energy-saving lamps. The voltage of DC energy-saving lamps is DC, which is convenient and safe without inverter.
Street lamps generally use 12V DC energy-saving lamps and low-pressure sodium lamps. Low-pressure sodium lamps have high efficiency but are relatively expensive, and are used less frequently.
