Abstract
In a typical large-scale solar system, thousands of solar modules are wired together, with thousands of connector connections performed manually by on-site installers. Such a process is time-consuming and subject to improper or loose connections for some modules. Described hereinafter are system and method embodiments of automatic module DC wiring to improve the installation quality, efficiency, and consistency for large-scale solar systems. A controller receives ambient images captured by a camera to identify and locate module connectors and operates a robotic arm to perform connector connection based on the identified and located connectors and also wiring schemes received from a server regarding the modules in the solar system. The robotic arm may also be controlled for connection verification to ensure the solar module is correctly wired. Implementation of the presented invention may greatly increase efficiency, consistency, and connection quality for module DC wiring.
