May I ask if photovoltaic panels can be installed on the roofs of Class C warehouses? Are there any specific requirements and standards?

Class C warehouses are also divided into different categories; it is not recommended to store items there! I have not seen relevant standards.

**The Energy Bureau has a document titled \"Notice on Strengthening the Safety of Distributed Photovoltaic Power Generation Projects (Draft for Comment)\“. It is strictly prohibited to build distributed photovoltaic power generation projects in buildings classified as Category A or Category B in terms of fire hazard. For buildings in Category C, an assessment is required; those in Categories D and E are permissible. The fire separation distance must be at least 30 meters. Attention must also be paid to whether the smoke and vapor emitted by chemical plants are corrosive. Photovoltaic panels are sensitive to strong acids and strong bases – strong bases can corrode the glass, while aluminum frames will also undergo chemical reactions when exposed to strong acids and bases, which can lead to leakage and short circuits on the DC side of the photovoltaic power plant. Recently, there have been reports that Sinopec plans to install photovoltaic panels uniformly on the canopies of its gas stations.

Now, new business models are emerging in large numbers, and standards and regulations fail to keep up with the pace of development.
