Photovoltaic power generation system is a new type of power generation method in the photovoltaic industry. At present, photovoltaic power generation systems are mainly used in the following occasions: households: including rural residents, etc.; factories and enterprises: including enterprises, factories, warehouses, buildings, transportation, etc.; schools: Including primary and secondary schools, junior high schools, high schools, etc.; various government agencies: including enterprises, institutions, communities, etc.
1. Resident families
Photovoltaic power generation systems are suitable for urban households, mainly in the following two ways: one is a household photovoltaic power generation system; the other is a distributed photovoltaic power generation system. Among them, the household photovoltaic power generation system is mainly based on household users, and supports the combined installation of unit users and industrial and commercial users, and the investment cost of project construction is low. At present, there are three main types of customers who install home photovoltaic power generation systems on the market. One is to install photovoltaic systems as the main body of villas, and the project cost is as high as 40,000 to 50,000 yuan; Photovoltaic power generation system; thirdly, household photovoltaic generator sets are the main components, and the project investment cost is low. There are two main ways for residential households to use photovoltaic power stations: one is as a rooftop centralized power station (domestic users are the main body); the other is to install photovoltaic projects on the roof as temporary electricity. At present, one of these two methods is the most widely used in the market, and this method is mostly used to install solar power generation systems in villas or some areas with courtyards; Used in rural areas.
2. Factory Enterprises
Mainly used in factories, industrial plants, large warehouses, etc. Due to the particularity of the factory, there will be a lot of equipment in the factory. In order to ensure the normal production and operation, a lot of equipment needs to be used. Traditionally, some large-scale equipment is installed in the factory area and left in an idle state, which leads to certain hidden dangers of electricity consumption in the factory. With the development of photovoltaic technology, large-scale factories are gradually developing towards distributed development. For factories and enterprises, distributed photovoltaic systems can reduce electricity costs and improve the factory environment; for individuals, they can save electricity costs; for users, they can enjoy multiple preferential policies such as electricity subsidies.
At present, there are many types of solar photovoltaic power generation equipment in use in schools, including electronic self-controlled air conditioning systems, centralized rooftop photovoltaic power generation systems, and distributed inverters. Since many schools on campus have installed distributed photovoltaic power generation systems, and photovoltaic power plants are generally large in scale, they are in the mainstream position in the school photovoltaic power generation market. According to relevant data, there are currently about 1.1 million ordinary primary and junior high schools in my country; about 1.33 million ordinary high schools; about 370,000 ordinary colleges and universities; about 1.04 million ordinary institutions of higher learning; There are about 1 million; there are about 1.3 million ordinary primary schools; and about 200,000 secondary vocational schools. In addition, nearly 1,000 primary and secondary schools in my country do not have distributed power systems; in addition, there are many primary and secondary schools that only install distributed power systems.
4. Government agencies
Government buildings generally set up some public and necessary public buildings, such as conference rooms, office buildings, offices, conference rooms and offices. The electricity consumption of these buildings is often very strong. Most of the government offices have long construction periods, and most of them require a large amount of electricity for support. Therefore, the use of clean energy such as solar energy for charging should be considered at the beginning of the design of these buildings.
