Photovoltaic power generation new energy system

The principle of photovoltaic power generation:

Photovoltaic power generation is a technology that converts light energy directly into electrical energy by using the photovoltaic effect of semiconductor interface. It is mainly composed of solar panels (components), controllers and inverters, and the main components are composed of electronic components. After the solar cells are packaged and protected in series, a large area of solar cell modules can be formed, and then combined with the power controller and other components to form a photovoltaic power generation device.

Advantages of photovoltaic power generation:

Photovoltaic power generation is a power generation method that uses solar radiation to convert into electricity, and its advantages are mainly reflected in the following aspects:

1. Renewable energy: photovoltaic power generation uses solar energy, which is an unlimited renewable energy, and there is no problem of resource depletion.

2. Clean and environmental protection: photovoltaic power generation will not produce harmful substances emissions, environmentally friendly, in line with the concept of green environmental protection.

3. Flexibility: photovoltaic power generation systems can be installed in various sizes and types of places, such as homes, industrial parks, buildings, etc., regardless of geographical location.

4. High efficiency: With the continuous progress of technology, the efficiency of photovoltaic power generation is getting higher and higher, and it can meet various electricity needs.

Application field:

(1) Small power supply ranging from 10-100W, used in remote areas without electricity such as plateau, island, pastoral areas, border posts and other military and civilian life electricity, such as lighting, television, radio recorders, etc.; (2) 3-5KW household roof grid-connected power generation system; (3) Photovoltaic water pump: solve the problem of deep water well drinking and irrigation in areas without electricity.

2. In the field of transportation, such as navigation lights, traffic/railway signal lights, traffic warning/sign lights, Yuxiang street lights, high-altitude obstacle lights, highway/railway wireless phone booths, unattended road shift power supply, etc.

Third, communication/communication field: solar unattended microwave relay station, optical cable maintenance station, broadcasting/communication/paging power system; Rural carrier telephone photovoltaic system, small communication machines, soldiers GPS power supply.

4. Petroleum, Marine and meteorological fields: cathodic protection solar power supply system for oil pipelines and reservoir gates, life and emergency power supply for oil drilling platforms, ocean testing equipment, meteorological/hydrological observation equipment, etc.

Fifth, home lighting power supply: such as garden lights, street lights, hand lights, camping lights, mountaineering lights, fishing lights, black light, rubber cutting lights, energy-saving lamps, etc.

6, photovoltaic power station: 10KW-50MW independent photovoltaic power station, wind (firewood) complementary power station, various large parking plant charging stations.

The combination of solar power generation and building materials makes the future of large buildings to achieve self-sufficiency in electricity, which is a major development direction in the future.

8.
