태양열 집열기 시장 - 세계 산업 규모, 점유율, 동향, 기회, 예측 : 유형별, 용도별, 지역별＆경쟁(2021-2031년)

The Global Solar Thermal Collector Market is projected to expand from USD 31.26 Billion in 2025 to USD 52.46 Billion by 2031, achieving a compound annual growth rate of 9.01%. Solar thermal collectors are specialized devices engineered to capture solar radiation and convert it into thermal energy by heating a fluid, serving various applications such as industrial processes, space heating, and residential water heating. The market is chiefly driven by the growing global demand for energy security and the critical need to decrease dependence on unstable fossil fuel imports. Additionally, strict government decarbonization mandates and financial incentives for renewable heating are fundamental factors promoting the adoption of sustainable thermal energy sources across commercial and residential sectors.

Despite these drivers, the industry faces a substantial hurdle from the rapid electrification of the heating sector, where photovoltaic systems and heat pumps compete fiercely for investment capital and limited installation space. This competitive environment creates significant challenges for traditional solar thermal technologies, particularly in established markets. Data from the IEA Solar Heating and Cooling Programme indicates that the global market saw a total of 17.8 gigawatts-thermal of newly installed solar thermal capacity in 2024. This statistic underscores the continuing struggle to sustain growth momentum as alternative electrification technologies increasingly dominate the landscape.

Market Driver

The proliferation of Large-Scale Solar District Heating Networks is fundamentally transforming the market by shifting investment focus from individual residential units to centralized, utility-grade infrastructure. Municipalities and utility providers are deploying megawatt-scale collector fields to supply renewable heat to city-wide grids, a strategy that decouples urban energy systems from volatile fossil fuel costs while facilitating seasonal thermal storage. This aggregation of demand improves system efficiencies and lowers levelized costs, enabling solar thermal solutions to compete effectively against electrification in the district energy sector. As noted in the 'Solar Heat Worldwide 2025' report published by the IEA Solar Heating and Cooling Programme in July 2025, the global sector commissioned 10 new large-scale solar district heating systems totaling 74 megawatts in 2024, highlighting the segment's resilience against broader market challenges.

Concurrently, the rising demand for Low-Carbon Industrial Process Heat is fueling adoption in industries that require reliable medium-to-high temperatures, such as food processing, chemicals, and mining. Industrial operators are increasingly adopting advanced concentrating solar collectors to reduce carbon emissions and ensure long-term energy price stability, particularly for processes where electric heat pumps face technical or economic limitations. According to a June 2025 article by Solarthermalworld.org titled 'Solar heat faces setbacks in buildings but industrial use and district heating expand,' the industrial segment saw 120 megawatts of newly installed capacity in 2024, representing a 28% year-on-year increase. This industrial growth contrasts sharply with stagnation in mature residential markets; for example, the German Solar Association (BSW-Solar) reported in 'Statistical data on the German Solar Heating Market' in March 2025 that Germany experienced a limited deployment of approximately 141 megawatts-thermal of new solar thermal capacity in 2024.

Market Challenge

The rapid electrification of the heating sector presents a formidable obstacle to the expansion of the solar thermal collector market. As commercial and residential property owners increasingly prioritize versatile energy systems, technologies such as heat pumps and photovoltaic (PV) units are absorbing a large share of available capital and finite installation space. Photovoltaic systems provide the distinct benefit of generating electricity to power a wide array of appliances, including electric heat pumps, offering an integrated energy solution that frequently displaces standalone thermal collectors. This technological shift narrows the addressable market for solar thermal devices, forcing them into a niche position where they must compete for the same physical roof area as their electric counterparts.

This competitive pressure is evident in recent performance metrics from major established markets. The Federal Association of the German Heating Industry (BDH) reported that sales of solar thermal systems dropped by approximately 40 percent in 2024 compared to the previous year. This significant decline highlights the direct consequences of the electrification trend, where the growing dominance of PV systems and heat pumps effectively crowds out traditional thermal technologies, thereby stalling broader market expansion.

Market Trends

The adoption of Hybrid Photovoltaic-Thermal (PVT) Collectors is gaining traction as a vital trend to address the spatial limitations imposed by the rapid electrification of building rooftops. As photovoltaic panels increasingly occupy available surface area, hybrid collectors provide a dual-function solution that generates both electricity and heat from the same footprint, maximizing energy yield per square meter for property owners. This technology is becoming increasingly popular in mature markets where roof space is at a premium and efficiency regulations are tightening, effectively transforming a competitive threat into a synergistic opportunity. As detailed in the July 2025 Solarthermalworld.org article 'Global PVT market in transition: growth returns after two-year slide,' the global market for newly installed PVT collectors expanded by 13 percent in 2024, reaching a total volume of 72,544 square meters as the technology moves beyond niche applications.

In parallel, the convergence of Solar Thermal with Heat Pump Systems is advancing as a strategic evolution to enhance overall system performance and decarbonize heating more effectively. Instead of operating as isolated competitors, solar thermal units are increasingly integrated to raise the source temperature for heat pumps, significantly improving their seasonal coefficient of performance (SCOP) and reducing electricity usage during peak demand periods. This integration utilizes the massive existing infrastructure of thermal collectors to create hybrid systems that are more resilient and efficient than standalone electric solutions. According to the 'Solar Heat Worldwide 2025' report by the IEA Solar Heating and Cooling Programme in July 2025, cumulative global solar thermal capacity in operation reached approximately 560 gigawatts-thermal, providing a substantial foundation for this hybridization trend to expand across residential and commercial sectors.
