As a key material for photovoltaic modules, photovoltaic glass, with the acceleration of global energy transition and the rapid development of the photovoltaic industry, has shown the following industry trends:
1. Demand continues to grow
A. Driven by photovoltaic installations: The global carbon neutrality goal has led to A sharp increase in photovoltaic installations, directly boosting the demand for photovoltaic glass.
B. The penetration rate of double-glass modules has increased: The proportion of bifacial power generation modules (double-glass) has been rising year by year
2. Technological upgrading and innovation
A. Thinning and lightweighting: To reduce the weight and cost of components, the thickness of glass is developing from 3.2mm to 2.0mm or even thinner, and it is necessary to break through the technical bottlenecks of strength and light transmittance.
B. High light transmittance coating: The coating technology enhances the light transmittance of the glass, directly improving the power generation efficiency of the components.
C. BIPV (Building Integrated Photovoltaic) : The rising demand for colored, curved, and customized photovoltaic glass is driving the development of differentiated products.
3. Capacity expansion
Capacity concentration: China accounts for over 90% of the global photovoltaic glass production capacity. In the future, capacity will still be concentrated in leading enterprises, and small and medium-sized enterprises will face cost and technological pressures.
4. Cost and Policy Challenges
A. Fluctuations in raw material prices: Fluctuations in the prices of soda ash and quartz sand affect profits
B. Energy consumption and environmental protection constraints: Photovoltaic glass is a high-energy-consuming industry, and low-carbon production is becoming a trend.
5. Risks of emerging technology substitution
A. Perovskite solar cell supporting requirements: If the commercialization of perovskite technology accelerates, TCO conductive glass or flexible glass that needs to be compatible is required. Existing enterprises need to make technical reserves in advance.
B. Glass-free components: Under the trend of lightweighting, in some scenarios, high-molecular backsheets may be used to replace glass, but the mainstream market still mainly relies on glass.
The photovoltaic glass industry will continue to grow along with the photovoltaic industry, but technological iteration, policy risks and cost control are the key variables. Leading enterprises are expected to consolidate their advantages through technological research and development, global layout and industrial chain integration.
