Strict adherence to relevant safety regulations is required during the installation, operation, and maintenance of solar panels (photovoltaic panels) to ensure personnel safety and proper equipment functioning. Since photovoltaic panels continuously generate electricity when exposed to sunlight-maintaining voltage at their output terminals even when not connected to a load-personnel performing installation, inspection, or dismantling must possess basic electrical safety knowledge and follow standard operating procedures to prevent accidents such as electric shocks or short circuits caused by improper handling.
During installation, ensure that mounting structures are secure and reliable and that the installation site has sufficient load-bearing capacity to withstand adverse weather conditions such as strong winds, heavy rain, ice, and snow. Workers must wear appropriate protective gear-including hard hats, safety harnesses, non-slip footwear, and insulating gloves-and implement fall-prevention measures, particularly when working at heights like on rooftops. Installation and maintenance work should be avoided during severe weather, such as thunderstorms or high winds, to minimize safety risks. Cable connections between panels must be secure to prevent overheating or electrical faults caused by poor contact.
During routine operation, the panels' appearance and performance should be inspected regularly for issues such as broken glass, frame deformation, damaged junction boxes, cable aging, or loose connections. If cracks, scorch marks, or abnormal heating are detected, use of the system must be halted immediately, and professional inspection and repair arranged. Cleaning should be performed during cooler weather using a soft cloth or sponge and clean water; the use of abrasive tools (like steel wool) or corrosive chemicals (such as strong acids or alkalis) must be avoided to prevent surface damage that could impair power generation efficiency and service life.
To ensure the long-term, safe, and stable operation of the photovoltaic system, a regular maintenance and inspection schedule should be established. This includes comprehensive checks of inverters, power distribution equipment, grounding systems, and lightning protection facilities to verify that all components are functioning correctly. Additionally, the area surrounding the panels should be kept tidy, with tree branches, debris, and accumulated snow promptly removed to prevent shading or structural damage to the panels. For the average user, photovoltaic power generation equipment should not be dismantled or modified without professional training; in the event of a malfunction, professional technicians should be contacted promptly. This approach ensures personal safety while also helping to extend the system's service life and improve overall power generation efficiency.
