Some friends mentioned how to realize the solar remote monitoring power generation system? This is also widely used in outdoor monitoring applications. Today, Beijing Zhaofengyuan Technology Co., Ltd. will take you to find out.
One, what is solar energy
Solar Energy generally refers to the radiant energy of sunlight, which is generally used to generate electricity in modern times. Since the formation of the earth, organisms have mainly survived by the heat and light provided by the sun. Since ancient times, humans have also understood that the sun can dry objects and use them as a method of preserving food, such as salt production and salted fish. However, with the reduction of fossil fuels, solar energy is deliberately developed further. There are two ways to use solar energy: passive utilization (photothermal conversion) and photoelectric conversion. Solar power is an emerging renewable energy source. In a broad sense, solar energy is the source of many energy on the earth, such as wind energy, chemical energy, potential energy of water, and so on. In billions of years, solar energy is an ideal energy source that is inexhaustible and inexhaustible.
Solar energy is both a primary energy source and a renewable energy source. It is rich in resources, can be used free of charge, does not require transportation, and does not pollute the environment. It has created a new life style for mankind, bringing society and mankind into an era of energy conservation and pollution reduction.
Two, The composition of solar power supply system
The solar power generation system is composed of a solar cell group, a solar controller, and a battery (group). If the output power is AC 220V or 110V and needs to be complementary to the mains, it is also necessary to configure an inverter and a smart switch for the mains.
1. solar cell arrays are solar panels
This is the core part of the solar photovoltaic power generation system. Its main function is to convert solar photons into electrical energy, thereby promoting the work of the load. Solar cells are divided into monocrystalline silicon solar cells, polycrystalline silicon solar cells, and amorphous silicon solar cells. The monocrystalline silicon battery is more durable than the other two types, has a longer service life (generally up to 20 years), and has high photoelectric conversion efficiency, making it the most commonly used battery.
2. solar charge controller
Its main job is to control the state of the entire system, and at the same time protect the battery from overcharging and overdischarging. In places where the temperature is particularly low, it also has a temperature compensation function.
3. solar deep cycle battery pack
storage battery, as the name suggests, is to store electricity. It mainly stores the electrical energy converted from solar panels, generally lead-acid batteries, which can be recycled for many times.
In the entire monitoring system. Some equipment needs to provide 220V, 110V AC power, and the direct output of solar energy is generally 12VDc, 24VDc, 48VDc. Therefore, in order to provide power to 22VAC and 11OVAc equipment, a DC/AC inverter must be added to the system to convert the DC power generated in the solar photovoltaic power generation system into AC power.
