In recent years, the photovoltaic industry has developed rapidly, in the world economy continues to develop, the industrial demand for energy continues to increase, and traditional fossil fuels can’t meet the demand, while with the enhancement of people’s environmental awareness, a clean energy is the trend of The Times. Solar energy as a renewable energy, can bring us long-term effective energy supply, such as photovoltaic power stations and household photovoltaic systems, but many people do not know how to install photovoltaic home systems, in this blog, we will discuss the installation process of photovoltaic home appliances and solar solutions.
Photovoltaic Home Appliances and Solar Solutions
Installation Process
Installing a home photovoltaic system is simple and requires five main things: solar panels; a Photovoltaic bus box; a Photovoltaic inverter; Solar support; and Cable lines.
Solar Panel
Solar panels are the core part of the solar power generation system, the role of solar panels is to convert the sun’s light energy into electrical energy, and the output direct current is stored in the battery. Solar panels are one of the most important components in solar power generation systems, and their conversion rate and service life are important factors in determining whether solar cells have useful value.
Photovoltaic Bus Box
The PV bus box is used to connect the PV module and the inverter, provide lightning protection and overcurrent protection, and monitor the single series current, voltage, lightning arrester status, and circuit breaker status of the PV module. In the solar photovoltaic power generation system, in order to reduce the connection between solar photovoltaic cells and inverters, users can connect a certain number of photovoltaic cells with the same specifications in series to form a photovoltaic panel, and then connect several photovoltaic series in parallel to the intelligent photovoltaic junction box, after the intelligent photovoltaic junction box, through the DC circuit breaker output. It is used with a photovoltaic inverter to form a complete photovoltaic power generation system and realize grid connection with the mains.
Photovoltaic Inverter
Inverter is a power adjustment device composed of semiconductor devices, the electricity generated by solar panels is direct current, household appliances can’t be used directly, must be converted into alternating current through the inverter can be used at home. There are many types of inverters, so special attention should be paid to the selection of machine types and capacities. Especially in the solar power generation system, the efficiency of the inverter is an important factor in determining the capacity of the solar cell and the capacity of the battery.
Solar Photovoltaic Stand
A solar photovoltaic bracket is a special bracket designed for placing, installing, and fixing solar panels in the solar photovoltaic power generation system. General materials are aluminum alloy, and stainless steel, after hot dip galvanizing treatment after a longer service life. The bracket is mainly divided into two categories: fixed and automatic tracking. At present, some fixed brackets on the market can also make certain adjustments according to the seasonal changes in the sun’s light, just like when it was installed, the bevel of each solar panel can be adjusted to adapt to different angles of light by moving fasteners, and the solar panel can be accurately fixed in the specified position by fastening again.
Cable
As mentioned above, the inverter is to convert the direct current generated by the solar panel into alternating current, and then we call the DC side of the solar panel the DC side of the inverter part (DC side), and the DC side needs to use a special DC cable for photovoltaic (DC cable). In addition, as far as photovoltaic applications are concerned, solar energy systems are often used under harsh environmental conditions, such as strong ultraviolet light, drastic temperature changes, etc. This stipulates that photovoltaic cables must have the best weather resistance, UV linearity, and ozone erosion resistance, and can withstand a wider range of temperature changes. Therefore, it is recommended to use special cables for solar applications, which will affect the service life of the entire system.
Conclusion
The limited future of non-renewable energy makes it necessary for humans to find ways to create a more environmentally friendly power system, which can support human life and protect the earth’s environment.
