What are the advantages of solar energy compared with other energy sources?
 
As the earth's resources become increasingly scarce, the investment cost of basic energy is increasing, and various safety and pollution hazards can be said to be everywhere. Solar energy as a kind of "inexhaustible and inexhaustible" safe and environmentally friendly new energy source The more important it is. At the same time, with the development and progress of solar photovoltaic technology, solar lighting products have the dual advantages of environmental protection and energy saving. The application of led solar street lighting, solar garden lights, and solar lawn lights has gradually taken shape. Solar power generation has been developed in the field of street lighting. Improving day by day.
 
Solar energy is energy from celestial bodies outside the earth, and most of the energy needed by mankind comes directly or indirectly from the sun. Solar power is a new and renewable energy that can be applied to solar street lights and so on. There are three main sources of existing electric energy, namely thermal power, Hydropower and nuclear power.
 
Thermal power needs to burn fossi l fuels such as coal and petroleum. On the one hand, fossi l fuel reserves are limited, and the more they burn, the less they are, and they are facing the danger of exhaustion. It is estimated that the world's oil resources will be exhausted in another 30 years. On the other hand, burning fuel will emit carbon dioxide and sulfur oxides, so it will cause the greenhouse effect and acid rain, and degrade the global environment.

Hydropower will inundate a lot of land, which may cause damage to the ecological environment, and once a large reservoir collapses, the consequences will be disastrous. In addition, a country's water resources are also limited, and they are also affected by the seasons.
 
Nuclear power is clean under normal circumstances, but in the event of a nuclear leak, the consequences are equally terrible. The accident at the Chernobyl nuclear power plant in the former Soviet Union has caused 9 million people to suffer varying degrees of damage, and the impact has not stopped.
 
While solar energy meets the conditions of new energy, one is that it is rich in reserves and will not be exhausted; the other is that it is safe and clean, and will not threaten humans and damage the environment. Since our country is an energy-scarce country, solar energy is an effective and inexhaustible clean energy and an indispensable and important means to develop a low-carbon economy.
 
So speaking of why solar outdoor street lights are so energy-saving, I have to talk about the working principle of Solar Street Lights Outdoor: in daytime, under light conditions, solar cell modules generate a certain electromotive force, and the solar cell array is formed through the series and parallel connection of the modules, which makes the voltage of the solar cell array. Meet the requirements of system input voltage. Then charge the battery through the charge and discharge controller, and store the electric energy converted from light energy. At night, the battery pack provides input power for the inverter. Through the function of the inverter, the DC power is converted into AC power, which is transmitted to the power distribution cabinet, and the power is supplied by the switching action of the power distribution cabinet.
 
The discharge of the battery pack is controlled by the controller to ensure the normal use of the battery. The photovoltaic power station system should also have limited-load protection and lightning protection devices to protect the system equipment from overload operation and avoid lightning strikes, and to maintain the safe use of system equipment.
