What is industrial and commercial rooftop distributed photovoltaic power generation

Author:


Energy is becoming an increasingly important issue of concern to the world. New energy such as solar energy has received more and more attention because of its renewable and clean characteristics, and photovoltaic power generation is an important form of large-scale use of solar energy.

As early as 1839, French scientist Becquerel discovered that light can produce potential differences in different parts of semiconductor materials. This phenomenon came to be known as the photovoltaic effect, or simply the photovoltaic effect. In 1954, American scientists Chabin and Pilson first manufactured practical monocrystalline silicon solar cells at Bell Labs in the United States, giving birth to practical photovoltaic power generation technology that converts solar energy into electricity.

Today, I will talk to you about photovoltaic power generation...

PV power generation concept

Photovoltaic power generation is a technology that uses photovoltaic special effects at semiconductor interfaces to directly convert light energy into electrical energy. It is mainly composed of three parts: solar panels (components), controllers and inverters, and the main components are composed of electronic components. After being connected in series, solar cells can form large-area solar cell modules through packaging protection, and then form photovoltaic power generation devices with power controllers and other components.

The working principle of photovoltaic power generation.

The main principle of photovoltaic power generation is the photoelectric effect of semiconductors. The photoelectric effect is a phenomenon in which light causes potential differences between inhomogeneous semiconductors or different parts of semiconductor bonding to metals. The first is the process of turning photons (light waves) into electrons and light energy into electrical energy, and the second is the process of forming voltage.

Market application.

In the "13th Five-Year Plan for Solar Energy Development" (hereinafter referred to as the "Plan") released by the National Energy Administration, it is proposed to vigorously promote rooftop distributed photovoltaic power generation and continue to build distributed photovoltaic application demonstration areas. Obviously, rooftop distributed photovoltaics will become an important direction for the development of photovoltaics in the future.

Commercial rooftops have always been the darling of the photovoltaic industry. The use of idle commercial roofs to build photovoltaic projects refers to the installation of photovoltaic power plants on the roof of factories or buildings to generate electricity, and the power generation can be used by itself, or it can be sold to the state on the grid, and the idle roof resources of enterprises can be fully utilized to generate income. According to statistics, China's existing construction area exceeds 40 billion square meters, of which residential buildings account for 70%, industrial buildings account for 15%, and public buildings account for 15%. Although from the data, the proportion of industrial buildings is not large, but combined with electricity fee income and the active participation of many enterprises, industrial building photovoltaic roof projects have great market potential. Industrial and commercial photovoltaics can not only reduce energy consumption, but also make full use of idle resources, play the role of energy conservation and emission reduction, and bring huge economic and environmental benefits to enterprises.

As a practitioner of industrial and commercial photovoltaics, Nenghuanbao actively responds to the call of national policies, carries out industrial and commercial distributed photovoltaic projects with products with full score standards of the leader, and also plays a leading role in new energy trading. At present, Nenghuanbao has successfully built dozens of photovoltaic power station projects such as Hebei Tengyao Distributed, Wang Zhi, Distributed, Jinan Coca-Cola Distributed, etc.

What are the advantages of installing so many industrial and commercial rooftop distributed photovoltaic power generation systems?

1. Reduce the use of high-priced electricity and peak power, and reduce enterprise operating costs.

2. Enjoy national and policy benefits and enjoy economic benefits.

3. Energy saving, emission reduction, low carbon emissions, green environmental protection.

4. The system is stable and reliable, and the service life can reach more than 30 years.

5. Modular design, convenient and flexible, simple maintenance in the later stage, no worries.

Based on the application and development of new energy, the distributed photovoltaic power generation system continues to carry out technological innovation, and effectively uses new energy such as solar energy with the help of energy Internet technology and GIS technology. Relying on the renewable resources of natural circulation, using the online intelligent visual management system, and the professional operation and maintenance team, it has made outstanding contributions to energy development, environmental protection and economic innovation.
