Components Installation and Design Considerations for Home Solar PV Systems

1. Precautions for the installation of home solar PV system components


The electrical installation of the PV components of the home solar PV system should refer to the corresponding regulations, including electrical regulations and power connection requirements. For specific terms, please contact the local power department. Please do not install PV modules on the roof without safety protection measures. The protection measures include fall protection, ladders and stairs, and personal protective equipment. At the same time, do not install or operate home solar PV systems in unfavorable environments, such as strong winds and gusts, wet and frosty roof surfaces, etc. In the case of sunlight, the home solar PV system will generate direct current, and the current will increase with the increase of light. If you touch the electronic circuit of the component, there is a risk of electric shock or burns, and a DC voltage of 30 volts or higher may even be fatal. People could buy high quality home solar PV system in Anern solar power store.


Therefore, in the process of installation and maintenance, it is necessary to cut off the power of the home solar PV system, or move them to a completely dark environment, or cover the surface of the module with an opaque material. If you operate the system in the sun, please use insulated tools and do not wear metal jewelry. In order to avoid the risk of electric arc and electric shock, do not disconnect the electrical connection while working under load. The plugs must be kept dry and clean to ensure that they are in good working condition. Do not insert other metal objects into the plug, or make electrical connections in any other way. Unless the electrical connection of the module is disconnected and you are wearing personal protective equipment, do not touch or operate the PV module of the home solar PV system with broken glass, peeling off the frame, and damaged back panel. Do not touch the wet module.


2. Precautions for the design of home solar PV system


The PV modules of the home solar PV system must be in a suitable building or other places where the modules are suitable for installation (such as the ground, the roof, the side elevation of the house, etc.). Generally, it is recommended to install the PV module with an inclination angle of more than 10 degrees, so as to play a self-cleaning effect when it rains. When one or more PV modules are partially or completely shaded, the system performance will be significantly reduced. Generally, it is recommended to install the modules in a place with no shade throughout the year to increase the power generation of the PV system. In places with frequent lightning activities, lightning protection devices must be installed for home solar PV systems.
