Do you know these basic knowledge of photovoltaic?

1. What is photovoltaic?

In 1887, Heinrich Hertz first discovered the photoelectric effect, in which certain substances produce a voltage when exposed to sunlight. The unit of voltage is the volt, so this phenomenon is also known as the photovoltaic effect, referred to as "photovoltaic".

2. What is photovoltaic power generation?

People use these special substances to make photovoltaic modules, components are exposed to sunlight in the material will produce the flow of electrons, through the manual guidance to produce direct current, and then through the inverter inverter conversion, into alternating current into the user and the grid, the conversion process from light energy to electrical energy is usually called "photovoltaic power generation".

In popular terms, photovoltaic power generation refers to the use of solar radiation directly into electricity generation, photovoltaic power generation is the mainstream of today's solar power generation, so now people often say that solar power is photovoltaic power generation.

3. What is distributed photovoltaic power generation?

Photovoltaic power generation is divided into centralized and distributed.

Centralized means concentrated solar power generation in a large site. For example, installing photovoltaic panels the size of hundreds of football fields on a desert to generate electricity.

Distributed photovoltaic power generation refers to the installation of photovoltaic power generation systems on the roofs, walls, open Spaces and other scattered places of buildings, and the electricity is directly supplied to nearby users, and the excess electricity is stored for backup or sold to the national grid.
