What is a solar power energy?
Normal energy resources can’t produce electricity independently. For example, water is essential for nuclear power generation. However, the solar energy is eco-friendly energy that can produce electricity purely from solar and photovoltaic power generation facilities without needing additional resources.
Solar energy is used in various forms. The most commonly use is the solar power generation, which uses solar cells to generate electricity.
Solar photovoltaic system configuration
To convert solar energy into electrical energy, we need the solar photovoltaic power generation systems. The solar PV system is structured differently depending on how it will be used. It is designed with various facilities such as solar panel, inverter and so on, according to the purpose of installation such as a off-grid power plant, a grid-connected power plant and grid-support.
Main equipment of solar PV system
Photovoltaic panels: The panel composed of solar photovoltaic cells converts solar energy into electricity (DC electricity) and is designed according to the capacity or the installation place.
Inverter: It’s a device which can convert converted DC electricity into alternating current electricity for family use.
Utilization of solar power generation system
Solar photovoltaic systems have many forms. The solar photovoltaic energy, such as large-scale solar power plants, small-scale solar power plants, solar power plants for family use, stand-alone solar power plants, streetlights and bus stations etc., is required for the infrastructure in our life. The solar power generation system is designed according to the type such as module, inverter, grid connection/, battery and monitoring system.
Advantages of solar energy
The electricity produced by solar photovoltaic power generation is a sustainable energy, and it is convenient energy that requires a little maintenance. It is an important energy source for the future with low impact on the surrounding environment and economic feasibility. The advantages of solar energy are summarized as below.
Sustainable eco-friendly energy
As long as the sun is rising, this solar energy can be used continuously and it is renewable. The sun does not produce any carbon dioxide and air pollutants for producing the electricity.
Maintenance convenience
Solar energy systems require little maintenance. Once a photovoltaic system is installed with a photovoltaic panel, electricity is automatically generated, and then you only have to check the status of the power generation through the monitoring system.
Influence on the surrounding environment
Photovoltaic panels don’t generate any noise and electromagnetic waves and the impact on the surrounding environment is very small.
Economic feasibility of solar energy
With the continuous development and the drop of prices on solar panels, the electric unit price generated by solar energy is becoming cheaper.
