Background technique

With the continuous development of social economy, non-renewable energy sources such as traditional oil and coal are gradually decreasing, and the problem of energy shortage is also in front of people, prompting people to continuously develop new energy-saving technologies to make up for this deficiency.

Among the many renewable resources, photovoltaic power generation and wind power generation are the two most promising energy technologies. Solar energy has the characteristics of low energy density and strong randomness. In the utilization of solar energy, it is difficult for a single solar power generation system to provide stable power output. Even if this can be done, a certain price must be paid, that is, to increase the capacity of the intermediate battery device . But the high initial investment is the bottleneck of the utilization of renewable resources. The complementary system of solar energy and battery can provide more stable power output, and can also reduce the capacity of the intermediate power storage system, especially when the solar power generation system stops outputting power due to lack of sunshine at night, the battery device can provide part or even all of the power , also greatly reduces the cost.

However, most of the existing solar street lamps also have unreasonable structures, unreasonable installation configurations, and many inappropriate problems in actual work. For example, there is a wind-solar hybrid street lamp whose battery and control system are exposed, and most of the equipment can be stolen with simple criminal tools. Others use high-power incandescent lamps. This kind of light source can still achieve the use effect when it is used initially, but it shows a strong light attenuation after one or two years, and its glare value is high, which is not conducive to lighting.
