1、 Circuit knowledge and electrical skills
Circuit knowledge and electrical skills are crucial when installing solar home power kits. Firstly, the installer needs to master the basic circuit principles, including the concepts of basic circuit parameters such as current, voltage, resistance, and their relationships. This helps installers understand how photovoltaic modules generate electricity and how to transmit it to the home grid. In addition, installers need to be familiar with circuit connection methods such as series and parallel connections to ensure correct connections between photovoltaic modules.
In terms of electrical skills, installers need to be proficient in using various electrical tools, such as wire strippers, screwdrivers, voltmeters, ammeters, etc. These tools are essential during the installation process, as they can help installers accurately complete circuit connections and testing. At the same time, installers also need to understand and comply with the national safety regulations for electrical installation to ensure that there will be no electrical fires, electric shocks, or other safety accidents during the installation process. This requires installers to have a high level of safety awareness and operational skills to ensure their own and others' safety.
2、 Solar energy technology knowledge
The core of a solar home power kit is photovoltaic modules, so installers need to have a certain level of solar technology knowledge. Firstly, installers need to understand the working principle and performance parameters of photovoltaic modules, such as power, efficiency, operating voltage, etc. These parameters are crucial for selecting suitable photovoltaic modules and inverters. Installers also need to understand the installation methods of photovoltaic modules, including fixing methods, wiring methods, etc., to ensure that the photovoltaic modules can work stably and reliably.
Inverter is another important component in solar household power kits. The installer needs to understand the functions, working principles, and selection principles of the inverter. Inverters can convert the direct current generated by photovoltaic modules into the alternating current required by household appliances, so their performance directly affects the efficiency and stability of the entire system. The installer needs to choose a suitable inverter based on the household's electricity demand and the power of the photovoltaic modules, and ensure that the connection between the inverter and the photovoltaic modules is correct and error free.
The energy storage system is also an indispensable part of the solar home power kit. The installer needs to have knowledge about the characteristics, capacity, charging and discharging management of batteries or other energy storage devices. Energy storage systems can provide power support during periods of low light or high electricity consumption, ensuring the stability and reliability of household electricity usage. The installer needs to choose a suitable energy storage system based on the household's electricity demand and lighting conditions, and regularly maintain and upkeep it.
3、 Construction skills and tool usage
The installation of solar household power kits requires certain construction skills and tool usage abilities. Firstly, the installer needs to develop a detailed construction plan, including the selection of installation locations, component layout, cable routing, etc. This helps ensure construction efficiency and quality, while reducing unnecessary waste and losses.
During the installation process, the installer needs to master the safety knowledge and operational skills of roof work. If photovoltaic modules need to be installed on the roof, the installer needs to understand the structure and load-bearing capacity of the roof, and take appropriate measures to ensure safety during the operation. At the same time, installers also need to be proficient in using various installation tools, such as drilling machines, screwdrivers, electric drills, etc. These tools can help installers accurately fix photovoltaic modules and other equipment in designated positions.
4、 Debugging and maintenance knowledge
After installation, the solar household power kit needs to undergo system debugging and testing. The installer needs to understand the debugging steps and methods of the system, be able to conduct system testing, and ensure that the connections between various components are correct and the performance is normal. This includes checking the output power of photovoltaic modules, the conversion efficiency of inverters, and the charging and discharging capabilities of energy storage systems.
During the operation of the system, various faults and problems may occur. Installers need to master common types of faults and diagnostic methods, and be able to quickly locate and solve problems. This requires installers to have high fault diagnosis and maintenance capabilities to ensure the stable operation of the system. At the same time, installers also need to regularly maintain and upkeep the system, including cleaning photovoltaic modules, checking cable connections, and replacing damaged components. These measures help to extend the service life of the system and improve its performance.
5、 Safety and environmental awareness
Safety and environmental awareness are also essential when installing solar home power kits. Firstly, installers need to maintain safety awareness at all times and pay attention to preventing safety accidents such as electric shock and falling. During the installation process, it is necessary to strictly comply with safety regulations to ensure the safety of oneself and others. At the same time, installers also need to understand the environmental benefits of solar home power kits, as well as the impact on the environment during installation and operation. During the installation process, active measures should be taken to reduce pollution and waste, such as rational use of materials and reduction of waste. During operation, attention should be paid to the energy efficiency and emissions of the system, and appropriate measures should be taken to improve the system's energy efficiency and reduce emissions.
