Determined by the longitude, latitude and optimal radiation amount of the installation area.
Due to the limitations of the installation conditions, the installation tilt of the module cannot reach the optimal angle and can be adjusted appropriately. The energy production of roofs not facing south will be greatly affected. . When the capacity of the power plant is certain, reducing the tilt angle can save land and cables and increase the wind resistance of the support. When the land area is certain, reducing the tilt angle can increase the installed capacity and power generation. increase income.
Photovoltaic panels are used for the production of photovoltaic energy. Photovoltaic power generation uses solar energy to produce electricity. Good or bad lighting of photovoltaic panelss directly determines the production of photovoltaic energy.
Installation method of photovoltaic power generation support
Photovoltaic power generation is a technology that uses the photovoltaic effect of the semi- conductive to directly convert light energy into electrical energy. Distributed photovoltaic power generation specifically refers to photovoltaic power generation facilities built near user sites for personal use and with surplus electricity connected to the grid. In simple terms, these are “individual photovoltaic plants scattered throughout the city”. Floor installation, as the name suggests, the plant is installed on the ground, then the tilting support is installed on the foundation. The solar components are fixed on the support. In some sites with slopes, the support can also use the supportt. slope of the hillside to directly install the foundation and support components. The main application object of the column installation is solar public lighting. Generally, solar photovoltaic power generation systems are installed on metal, concrete and wooden poles, pillars, towers, etc. Since the components are installed at a higher position, the fixing of the components and the wind resistance of the high-altitude installation must be considered.

What are the precautions for installing photovoltaic power plants on roofs?
The most important part of the photovoltaic industry is the utilization of photovoltaic modules to produce electricity and store electrical energy for power supply. What affects the operation of photovoltaic modules is the natural environment. When you use nature, you mustPay attention to the conditions of the natural environment. The current design of photovoltaic modules must be able to withstand bad weather. sand, wind, snow, humidity, rain, etc., as well as temperature and season.
First of all, the photovoltaic support must be capable of supporting a sufficiently large load. The photovoltaic battery should have good shock resistance under the impact of rain, sand, etc., and ensure effective light transmission. within 10 to 20 years. The surface must also be able to effectively prevent dust deposition and corrosion from various other substances. According to some maintenance data, many damages to photovoltaic system components are linked to natural deposits. Most of them are the battery cover, the surface of the packaging material and the seals of various components. In addition, temperature also has a significant impact on thes photovoltaic components. First, the cell efficiency of the photovoltaic system has certain effects at low temperatures.
The current photovoltaic system must therefore improve its ability to resist natural damage, such as bonding materials at joints. The materials used for packaging need to be improved. A lot of research is also being carried out on photovoltaic modules and panels to improve the cooling mechanism.
Photovoltaic systems have very strict requirements for where and how they are installed, so what are these requirements?
There are many types of photovoltaic power generation systems that we are familiar with, including grid-connected systems, off-grid systems and mains supplementary systems. These different types of systems have “strict” requirements for installation locations. and methods. SO,where is this hardness reflected?
The installation of photovoltaic power generation systems mainly refers to the installation of solar cell modules or solar cell arrays, as well as inverters, supports, etc. The location and installation method are also adapted to local conditions. , there are many forms, such as column installation, ground installation, roof installation, hillside installation, building installation and integrated building material installation , etc. Today we will talk about these types of installation methods.
The first type of column installation.
The main purpose of the application is solar street lighting. Generally speaking, the photovoltaic solar power generation system is installed in metal, concrete and wood poles, pillars, towers, etc. Since the components are installed at one positionhigher, the fixing of the components and the wind resistance of the installation at high altitude must be taken into account.
The second category is floor installation.
Floor installation. As the name suggests, the power plant is installed on the ground and then a tilting support is installed on the foundation. Solar modules are attached to the support on some sloping sites. , the supports can also be used on hillsides, etc. The inclined surface is directly used as a foundation and support to install the battery components.
The third type of roof installation.
It is very common to install photovoltaic systems on rural roofs. The first is to use the roof as a support and fix the battery components on the roof using special brackets or components to form a square array. it should be noted that there must be a space betweencomponents and roof. There is a certain space for ventilation and heat dissipation. The other is to directly combine the battery components with the roof to form a whole, also called; legacy of the photovoltaic field and the roof.
Category 4 wall-mounted installation.
Like roof installation, wall-mounted installation can be roughly divided into two types: one is to use the wall as a support and fixing the battery components on the wall using brackets or special components to form a square array, that is, the square array of solar cell modules is fixed externally to the wall of the unlit part of the building; the other is to transform photovoltaic modules into integrated photovoltaic building materials such as photovoltaic curtain wall glass and photovoltaic lighting glass windows. , which can be used as a material ofexterior wall of building and window lighting. It is directly applied to the building wall to form the integration of photovoltaic modules and building walls.
When installing a photovoltaic power plant on the roof, you should pay attention to the following aspects:
