Green Power Development Energy
Jun 08, 2018

Photovoltaic power plant refers to a photovoltaic power generation system that uses solar energy, adopts a power system composed of special materials such as crystalline silicon plates, inverters, and other electronic components, and is connected to the power grid and transmits power to the power grid. Photovoltaic power plants are currently the green power development energy projects that are the most encouraged by the state.

It can be divided into an independent power generation system with a battery and a grid-connected power generation system without a battery. Solar power is divided into solar thermal power generation and photovoltaic power generation. The current period of commercial solar energy refers to solar photovoltaic power generation.

Photovoltaic power generation products are mainly used in three major areas: first, providing power for non-electricity applications; second, solar-powered daily-use electronic products, such as various types of solar chargers, solar street lights, and solar meadows; and the third is grid-connected power generation. This has been widely implemented in developed countries. By 2009, China's grid-connected power generation has not yet begun to be fully promoted. However, part of the 2008 Beijing Olympic Games was powered by solar power and wind power.

Photovoltaic power generation is a technology that uses the photovoltaic effect of a semiconductor interface to convert light energy directly into electrical energy. The key element of this technology is solar cells. After the solar cells are encapsulated and protected in series, a large area solar cell module can be formed, and a photovoltaic power generation device can be formed by combining the power controller and other components.

The solar photovoltaic module converts direct sunlight into direct current, and the photovoltaic strings are connected in parallel to the DC distribution cabinet through the DC convergence box. After the convergence, the inverter is connected to the DC input terminal of the inverter, and the DC power is converted into AC power, and the AC output of the inverter is terminated. Into the AC distribution cabinet, directly into the user side through the AC distribution cabinet.
