The National Energy Administration recently released installed capacity data for the first quarter of this year, showing a total of 45.74 GW of new grid-connected capacity, including 21.93 GW from centralized power plants and 23.81 GW from distributed photovoltaic (PV). With the distributed PV market expanding southward in the past two years, the residential and commercial markets are gradually shifting accordingly. Leveraging the developed economies of the southeast coast and riverside areas, the potential commercial and industrial PV market is gradually opening up. It is understood that my country currently has 6.7 billion square meters of existing industrial and 3.4 billion square meters of completed floor space, with annual increases of 500 million square meters and 250 million square meters respectively. Taking industrial rooftops as an example, assuming half of these rooftops are equipped with PV, the future market for industrial rooftop PV alone could reach at least 500 GW. Compared to the frequent setbacks in the residential market, the development of commercial and industrial PV has indeed progressed steadily in the past two years. Under the backdrop of "dual carbon" goals, more and more industrial plants are seeking integration with new energy sources. Strong winds, leaks, corrosion... what are the challenges facing commercial and industrial PV? While the market for distributed photovoltaic (PV) systems is currently enormous, several unresolved issues have become stumbling blocks in its implementation. There are many types of roofs suitable for PV installation, such as reinforced concrete, steel-framed corrugated steel roofs, and parking sheds. Many industrial and commercial roofs are primarily constructed with steel-framed corrugated steel roofs, which are prone to rust and aging due to rain erosion and lack of maintenance. Such roofs are difficult to insure with insurance companies. In our survey, the primary concern for factory roof owners installing PV systems was leakage. Standard corrugated steel roofs typically require drilling for installation, which inevitably leads to rainwater seepage at the joints over time. If maintenance is not timely, it will only exacerbate the potential dangers of the entire roof. This is a fatal flaw for industrial and commercial roofs and is the primary concern for owners. As we all know, most factory roofs are made of corrugated steel sheets, and the lifespan of these sheets is only about 10 years. In areas like the southeast coast or regions with frequent rainfall, the lifespan is even shorter. However, photovoltaic (PV) power stations typically operate for 25 years or more. This raises the issue of a mismatch between the lifespan of the power station and the roof. This means that after 10 years of operation, the roof needs to be completely replaced, and the power station needs to be dismantled and reinstalled simultaneously, further increasing costs. This dilemma often forces owners to address both roof waterproofing and the power station construction, but ultimately, the core issue remains the roof. Solving the roof problem will naturally resolve the pain points of rooftop PV.
