The pros and cons of the various components of the solar garden light will affect the success or failure of the entire equipment

　　The output power of solar cell modules should be determined according to the power of the light source of the solar garden light, the time of use, and the local climate and geographical conditions. During the use of solar cell modules, heat island effects may occur. In order to prevent the heat island effect, the solar cells are generally placed obliquely so that the surface of the solar cell panels cannot be attached with obstructions.　　 A good performance controller should have various protection functions such as controlling battery charging and discharging, temperature regulation, overcharge/discharge protection, short circuit protection, reverse connection protection, etc., as well as automatic switching and time adjustment functions. The controller must also ensure the reliable operation of this system, so that the solar cell modules can intelligently output the maximum power under different temperature and irradiation conditions, so that the lighting system has a higher efficiency.　　Because the battery of the solar lighting system is charged directly by the solar battery, the energy obtained is not stable. All batteries with reasonable capacity and reliable performance must be equipped to ensure that the solar garden lights can work normally. Moreover, it must be able to meet the requirements of night lighting, and be able to store the energy converted by solar cell modules during the day, and at the same time meet the electrical energy required for continuous rainy days and night lighting. Therefore, the capacity of the battery must be reasonable, otherwise the battery capacity is too small to meet the needs of night lighting, and the battery capacity is too large, the battery will be in a state of power loss for a long time, shorten the battery life, and cause unnecessary waste.　　The light source of the solar garden light can be selected from a variety of light sources such as LED light sources, DC energy-saving lamps, low-pressure sodium lamps, etc. according to the actual situation. No matter which kind of light source is selected, its brightness is directly related to the power of the light source, and directly affects the system configuration and investment costs.
