Advantages of photovoltaic power generation: a. High solar energy utilization efficiency and little impact on the environment; b. Light energy can directly generate electricity, with minimal loss in the transmission process; c. Clean and pollution-free, no pollution to the air; d. Less land occupation, It occupies a small space, is a green and environmentally friendly power generation method, and can improve energy utilization.
1. What is a distributed photovoltaic power generation system combined with buildings?
Distributed photovoltaic system, also known as distributed building energy system, refers to the photovoltaic power station in the building, the photovoltaic power generation modules are arranged on the roof according to the needs, and the photovoltaic cell components are installed in the building through special brackets or mobile brackets , and then generate electricity through the photoelectric conversion system, bringing a steady stream of clean energy to the building - photovoltaic power generation system. The technical principle is: the photovoltaic power generation module converts solar energy into electrical energy, and then converts the electrical energy into electrical energy through the photoelectric conversion system and transmits it to the grid for use by the grid. Distributed photovoltaic power generation system The most widely used and largest solar photovoltaic power generation system is developed in large cities. A large modern solar photovoltaic power station is built using the distributed photovoltaic power generation system, and "ground photovoltaic" is used as the photovoltaic power generation system to install. Main body and power generation equipment; in large cities, a small distributed photovoltaic power generation system has also been developed. In big cities, there are also many small-scale household photovoltaic power generation systems that can be installed on residential roofs. This distributed photovoltaic power generation system with households or small businesses as the main body is stable and reliable, and can greatly improve energy utilization and reduce carbon emissions. ;Because the construction and operation and maintenance are mainly carried out by households, it can reduce electricity expenses and achieve stable income; and can obtain electricity while ensuring normal work and operation to ensure the normal operation of enterprises and maintain their own corporate interests. At present, many residential communities have carried out pilot applications of this technology.
2. How to install a distributed photovoltaic power generation system?
The installation of photovoltaic power generation system involves safety issues. It is necessary to choose safe and reliable photovoltaic modules. The quality and reliability of photovoltaic system products are directly related to the life and operation quality of photovoltaic system products. Therefore, it is particularly important to choose a reliable brand. Photovoltaic modules are usually selected for household photovoltaic power generation systems, mainly considering the impact and stability of distributed power generation systems on the environment. If you want to install photovoltaic modules in a household photovoltaic power generation system, you must ensure that all components are free of any problems before they can be installed and connected to the grid. System design must be done before installation. After the system design plan is determined, the photovoltaic building integrated design can be installed. It is necessary to design whether the roof construction area of the photovoltaic system meets the installation conditions and whether there are factors such as sunlight shading.
3. What matters should be paid attention to in the construction?
a. Determine the type of roof, generally choose a roof with a large roof area but poor lighting, or you can choose a roof with a small roof area but better lighting than the roof.
b. Determine the building structure. Generally, the building structure will be waterproof on the roof, and the roof waterproofing can be done better;
c. Determine the capacity of the photovoltaic power station. Generally, the installed capacity depends on the building type, power consumption, voltage level and other factors;
d. Determine the component selection, generally need to use polysilicon, PVDF or PVDF + GaN bipolar plate components;
e. To do a good job in the project investment budget, select the appropriate project investment budget amount, construction cost and future income, so as to obtain good income;
f. The construction of distributed photovoltaic power stations must meet relevant specifications, such as building seismic fortification, photovoltaic power generation system voltage level selection, photovoltaic module spacing requirements, inverter power factor selection, grid connection method selection, etc.
