Solar Glass Market Overview

The Solar Glass Market size was valued at USD 5192.75 million in 2024 and is expected to reach USD 8862.23 million by 2033, growing at a CAGR of 5.9% from 2025 to 2033.

The solar glass market is witnessing robust growth due to escalating solar panel installations globally. In 2023, global photovoltaic (PV) capacity additions surpassed 295 gigawatts (GW), significantly driving the demand for solar glass. Solar glass is a vital component in solar photovoltaic modules, offering high transparency, thermal resistance, and durability.

More than 75% of the solar modules manufactured worldwide use tempered solar glass. In China alone, over 180 GW of solar capacity was added in 2023, pushing the consumption of solar glass beyond 600 million square meters. Countries such as India, Germany, the United States, and Australia are experiencing sharp increases in solar power adoption, amplifying the need for high-quality solar glass. In India, solar installations exceeded 18 GW in 2023, creating a demand of over 65 million square meters of solar glass.

Furthermore, the advancement of bifacial and thin-film solar technologies is propelling the adoption of anti-reflective and TCO-coated glass. Investments in solar projects by both public and private sectors are intensifying, with solar glass manufacturing plants expanding in regions like Southeast Asia, the Middle East, and Europe.

Key Findings

DRIVER: Surging global solar power installations are directly increasing demand for solar glass.

COUNTRY/REGION: China dominates with over 60% of global solar glass production and usage.

SEGMENT: Tempered glass accounts for the highest consumption due to its mechanical strength and thermal stability.

Solar Glass Market Trends

One of the most significant trends in the solar glass market is the growing popularity of bifacial solar modules. These modules can generate power from both sides, leading to an efficiency increase of up to 15%. As of 2023, bifacial module deployment accounted for nearly 30% of new installations globally, requiring ultra-clear and anti-reflective solar glass. Another major trend is the adoption of thinner solar glass—2.0 mm and below—aimed at reducing module weight without compromising durability. Approximately 40% of new solar panels manufactured in 2023 utilized glass in the 2.0 mm range. The trend towards domestic solar glass manufacturing is strengthening due to trade restrictions and rising import tariffs. For instance, in the United States, domestic production increased by 18% in 2023 due to the Inflation Reduction Act incentivizing local manufacturing. In India, local manufacturers added over 400 tons/day of solar glass capacity in 2023 to meet rising demand and reduce reliance on Chinese imports. Solar glazing for building-integrated photovoltaics (BIPV) is another emerging trend. In Europe, BIPV projects in France, Germany, and the Netherlands saw a 25% rise in 2023, with solar glass used for both facades and rooftops. Colored and patterned solar glass for aesthetic architectural integration is also growing in popularity. Environmental regulations and ESG commitments are pushing manufacturers to adopt low-iron and lead-free glass formulations. Over 70% of solar glass producers have committed to net-zero emissions targets, driving R&D investments into sustainable manufacturing techniques.

Solar Glass Market Dynamics

Market dynamics refer to the constantly evolving forces that influence the supply and demand conditions within the solar glass industry. These dynamics include four key components: drivers, restraints, opportunities, and challenges, each of which plays a critical role in shaping market growth, competitive strategy, and product innovation. In the solar glass market, dynamics are influenced by global solar power adoption trends, raw material fluctuations, policy environments, and advancements in photovoltaic technologies.

DRIVER

Rising solar PV installations worldwide.

The rapid global shift towards renewable energy is the primary driver for solar glass market growth. In 2023, global solar energy installations increased by 42%, reaching 295 GW, creating a surge in demand for high-performance solar glass. China accounted for more than 60% of global installations, while India and the United States installed over 18 GW and 32 GW, respectively. With each megawatt of solar capacity requiring approximately 3,200 square meters of solar glass, the demand surpassed 900 million square meters globally. Government subsidies, net metering policies, and carbon neutrality targets are fuelling new solar projects. Additionally, large-scale solar farms across the Middle East and Southeast Asia are contributing to volume growth.

RESTRAINT

Volatility in raw material prices and supply chain constraints.

One of the key restraints is the rising cost and unpredictable availability of raw materials such as silica sand, soda ash, and dolomite. In 2023, the price of soda ash increased by nearly 22% globally due to supply chain bottlenecks and energy cost surges. Glass furnaces also consume significant energy, making them vulnerable to spikes in electricity and natural gas prices. In Europe, energy costs for glass manufacturing rose by over 30% in 2023, affecting production margins. Import restrictions and logistical disruptions post-pandemic have further limited raw material access, particularly in emerging economies.

OPPORTUNITY

Integration of solar glass into green building and BIPV applications.

The growing demand for sustainable construction is creating new opportunities for solar glass in BIPV applications. In 2023, the global BIPV market crossed 6.5 GW of installations, with Europe and North America accounting for more than 60%. Solar glass is increasingly being used in curtain walls, skylights, and sunshades. Technological innovations are enabling the development of semi-transparent and colored solar glass that meets both energy and aesthetic requirements. With building energy efficiency regulations becoming stricter—such as the EU’s EPBD targets—architects are actively integrating solar glass in new building designs.

CHALLENGE

Limited technological standardization and recycling challenges.

One of the main challenges is the lack of uniform global standards for solar glass specifications, leading to compatibility and quality control issues. Module manufacturers face difficulties sourcing standardized products across regions. Additionally, solar glass recycling remains a complex process. Less than 20% of end-of-life solar modules are currently recycled, and extracting solar glass without contamination is technologically demanding. Without advanced recycling infrastructure, the market risks future sustainability hurdles as module decommissioning increases after 25–30 years of service life.

Solar Glass Market Segmentation

The solar glass market is segmented by type and application. By type, the market includes AR coated glass, tempered glass, TCO glass, and other variants. By application, the major segments are silicon solar cells and thin-film solar cells. Each type and application has a specific use case depending on the technology employed in solar modules and regional preferences.

In 2023, over 420 million square meters of AR coated glass were used globally. It is preferred in bifacial modules and desert-based solar farms due to its glare-reducing properties. China and India are the top consumers, with over 150 million square meters installed in each country.
Tempered Glass: Tempered glass remains the most widely used type due to its mechanical robustness and heat resistance. Over 65% of solar modules manufactured globally in 2023 used tempered glass, totaling more than 700 million square meters. It can withstand temperatures over 200°C and wind loads exceeding 2,400 pascals, making it ideal for utility-scale projects.
TCO Glass: Transparent conductive oxide (TCO) glass is used primarily in thin-film solar modules, such as cadmium telluride and CIGS. TCO glass allows conductivity while maintaining transparency. In 2023, approximately 85 million square meters of TCO glass were consumed, with major usage in the U.S. and Japan. Companies like First Solar prefer TCO glass for its excellent light trapping.
