In fact, what should be paid attention to when choosing the battery capacity of solar street lights? How to choose? Let the solar lamp factory lighting answer for everyone below. On the premise of being able to satisfy the lighting at night, the energy of solar cell modules during the day should be stored as much as possible, and at the same time, it should be able to store the electric energy needed for lighting at night on cloudy and rainy days for several days. The capacity of the solar street lamp battery is too small to meet the needs of night lighting. The battery is too large. On the one hand, the battery is always in a state of power loss, which affects the battery life and causes cost waste. The battery should match the solar panels and street lights. A simple method can be used to determine the relationship between them. The solar cell power must be more than 4 times higher than the load power for the system to work normally. The voltage of the solar cell must exceed the working voltage of the battery by 20~30% to ensure that the battery is normal. The battery capacity must be more than 6 times the maximum daily consumption of the load. Knowing the selection method of solar street lamp battery, you can match the best configuration when purchasing solar street lamp, so that the life time of solar street lamp can be guaranteed.
