Photovoltaic street lamp system is a kind of lighting system using solar energy to generate electricity, which has the advantages of environmental protection, energy saving and reliability. The following is the design scheme of photovoltaic street lamp system for reference:

1. Selection of photovoltaic panels: Select high-efficiency photovoltaic panels, such as monocrystalline silicon or polycrystalline silicon panels, to ensure the maximum conversion efficiency of light energy.

2. Battery selection: Choose a deep cycle battery suitable for the solar photovoltaic street lamp system to ensure the long life and stable performance of the battery.

3. Controller selection: Choose a solar controller with intelligent control function, which can automatically adjust the brightness of the light according to the light intensity, and has the functions of overcharge, overdischarge and short circuit protection.

4. Selection of lamps: LED lamps with high efficiency and energy saving are selected, which have the characteristics of long life, high brightness and low energy consumption, and are suitable for the lighting requirements of solar photovoltaic street lamp system.

5. Bracket selection: Choose a stable and reliable bracket to ensure that the photovoltaic panel can work normally and adjust the angle to obtain the best solar energy conversion efficiency.

6. Energy storage selection: Select appropriate energy storage devices, such as supercapacitors or energy storage batteries, to ensure continuous power supply at night.

7. System layout: According to the actual situation, reasonably arrange photovoltaic panels, batteries, controllers, lamps and other equipment to ensure the overall performance and beauty of the system.

8. System monitoring: installing a remote monitoring system can monitor the working state of the photovoltaic street lamp system in real time and find and solve problems in time.

9. Maintenance: regularly maintain the photovoltaic street lamp system, such as cleaning photovoltaic panels, checking battery status, replacing lamps, etc. To ensure the normal operation and service life of the system.

In a word, the design of photovoltaic street lamp system needs to consider many factors such as photovoltaic panel, battery, controller, lamps and so on to ensure the efficient, stable and reliable operation of the system. At the same time, reasonable layout and maintenance should be carried out according to the actual situation to improve the overall performance and life of the system.
