Solar Glass Industry Outlook 2025:

The growing global emphasis on renewable energy sources is a primary driver for the solar glass market, as solar glass is a critical component in photovoltaic (PV) panels used for solar power generation. Governments worldwide are setting ambitious targets to increase solar capacity, for example, the International Energy Agency (IEA) reports that global solar PV capacity has tripled during 2018 to 2025. This surge is propelled by supportive policies such as tax incentives, subsidies, and renewable energy mandates, particularly in countries like China, India, the United States, and the European Union. Additionally, advances in solar technology have increased the efficiency of PV cells, necessitating higher-quality solar glass with superior light transmittance and durability, driving demand for low-iron, tempered, and anti-reflective glass variants. The construction sector’s shift towards green buildings and the expanding adoption of building-integrated photovoltaics (BIPV) also contribute significantly to solar glass demand. Furthermore, rising environmental concerns and decreasing costs of solar power systems make solar energy more accessible, encouraging utility-scale solar farm developments and distributed solar installations. The Solar Energy Technologies Office of the U.S. Department of Energy points out that over the past ten years, solar electricity prices have decreased by 90% due to the decreasing costs and increased efficiency of solar panels, which has further fueled industry expansion. Lastly, supply chain improvements and increased production capacities by major glass manufacturers globally have enabled meeting the accelerating demand, solidifying solar glass as a key enabler in the global energy transition.

Solar Glass Market Trends and Growth Drivers:

Increasing use of solar PV in energy transition worldwide

One of the key trends fueling demand in the solar glass market is the record global expansion of solar photovoltaic (PV) power generation, directly increasing demand for high-performance solar glass. According to the International Energy Agency (IEA), solar PV accounted for about 75% of all renewable capacity additions globally in 2023, making it the renewable power technology with the greatest rate of growth. This acceleration is led largely by policy support in the form of the U.S. Inflation Reduction Act, which backed more than 32 GW of PV installations in 2023 (a 70% year-over-year increase), and the European Union's REPowerEU initiative, which spurred 63 GW of installations in 2023, and 66 GW of new solar energy capacity installed in 2024. In China, the world's biggest solar market, installations reached an all-time high of nearly 217 GW in 2023 alone. Additionally, the price of PV modules fell by approximately 50% from December 2022 to December 2023, further turning solar power into a competitive source of energy and propelling deployments in developing countries like India, Vietnam, and Brazil.

Inching higher investments in local solar manufacturing and glassmaking

Concurrently with the deployment of solar, solar module manufacturing capacity around the world is experiencing colossal growth. According to IEA estimates, the global capacity to produce solar modules has been significantly high after 2021. Specifically, local manufacturing efforts in the U.S., India, and Europe are encouraging backward integration into manufacturing solar glass. For example, India's Production Linked Incentive (PLI) program is spurring investments in integrated solar module factories with standalone solar glass lines. Equally, European manufacturers are increasing low-iron solar glass capacity to facilitate regional solar panel manufacturing as China, which has historically commanded well over 90% of world solar glass capacity, faces increasingly loud demands from downstream buyers for supply chain diversification. Technology advancements like ultra-thin, anti-reflective, tempered, and bifacial-compatible glass are also improving module efficiency and pushing replacement demand on older installations. In 2023, global investments in solar PV capacity expansions climbed by around 30% to approach USD 480 billion, setting yet another record. In 2023, investments in solar photovoltaics exceeded those in all other power production technologies combined.
