How to Prevent Fire Risks in Photovoltaic Power Stations
With the development of the photovoltaic industry, the number of photovoltaic power stations is continuously increasing. Today, Hengyuantai will discuss how to prevent fire risks in photovoltaic power stations.
Photovoltaic modules and inverters must be well-ventilated. Generally, during the design of photovoltaic power stations, the brackets are elevated to ensure sufficient space around the modules, promoting airflow to achieve cooling. Additionally, the metal frames surrounding the modules also contribute to heat dissipation.
Inverters should have shading measures. In summer, high ambient temperatures can cause various components within the inverter to generate excess heat during operation, reducing power generation efficiency and potentially impacting component lifespan. Therefore, some residential photovoltaic systems have inverters installed with shading canopies to lower equipment temperatures. Moreover, the installation environment for inverters should ensure proper shading and ventilation to facilitate air circulation, which can enhance power generation.
Ensure there are no weeds or obstructions around the power station. Some ground-mounted stations, due to their remote locations, may be surrounded by dense weeds and vegetation, which can impede airflow and cause overheating. Additionally, overgrown weeds, debris, or bird droppings can obstruct sunlight and reduce power output. Regular inspections should be conducted to clear weeds, droppings, and other obstructions promptly.
Do not spray water on modules to cool them during high-temperature periods. If insulation and grounding are not properly protected during design and installation, there may be a risk of electric shock.
This concludes Hengyuantai’s introduction on how to prevent fire risks in photovoltaic power stations.
