The location for module installation should be free from any shading or obstructions throughout the year, and have ample sunlight exposure.On-grid Solar PV Systems generates electricity from light, so please choose an appropriate installation angle to ensure the modules receive the maximum amount of sunlight. The choice of module location should comply with various electrical and fire safety regulations.
When installing the brackets, you should follow the guidelines and safety rules provided in the manual attached to the brackets. The modules are already designed at the factory, so do not attempt to alter the structure or construction of the modules. Under standard installation, secure the modules to the brackets using the four symmetrical mounting holes on the inside of the frame. The brackets and other necessary supplies (such as bolts, etc.) should be made of durable, rust-proof, and UV-resistant materials.
For ground installations, choose an appropriate installation height to prevent the lower part of the modules from being covered by snow for extended periods during winter. Additionally, ensure that the lowest part of the modules is high enough to avoid obstructions from vegetation or trees and to prevent damage from windblown sand and stones. For rooftop installations, check the building codes in use to ensure the building and its structure (roof, facade, load-bearing, etc.) have adequate load-bearing capacity for the modules. When installing On-grid Solar PV Systems, ensure that the modules are installed on a fire-resistant roof, and that the roof pitch is less than 5 inches/ foot to ensure its fire rating. When installing modules on roofs or buildings, make sure they are securely fixed and will not be damaged by strong winds or heavy snow. Ensure proper ventilation at the back of the modules (a minimum gap of 10 cm between the modules and the mounting surface). For rooftop installations, the roof penetrations needed to secure the modules should be properly sealed to prevent water leakage.
Use the same configuration of modules in the same photovoltaic power generation system. If the On-grid Solar PV Systems is connected in series, the total voltage equals the sum of the voltages of each module. If the photovoltaic modules are connected in parallel, the total current equals the sum of the currents of each module. The modules come with prefabricated connectors for the system's electrical connections. The cross-sectional area of the cables and the connector capacity selected for the system should meet the maximum system short-circuit current. During module installation, the end with the junction box on the back should face upward. When designing the system, avoid forming loops. Before start-up, check the wiring to ensure that connections are secure and tight. Plugs should not be subjected to external pressure and should only be used for connecting lines, not for opening and closing circuits.
