태양열 해수 담수화 플랜트 시장 기회, 성장요인, 업계 동향 분석 및 예측(2026-2035년)

The Global Solar Water Desalination Plant Market was valued at USD 2.8 billion in 2025 and is estimated to grow at a CAGR of 10% to reach USD 7 billion by 2035.

The strong growth reflects intensifying pressure on global freshwater resources and the increasing need for sustainable water generation solutions. Solar desalination systems convert saline water into usable freshwater by leveraging thermal energy, positioning them as an environmentally aligned alternative to conventional treatment technologies. Rising awareness around resource conservation and long-term water security continues to accelerate adoption across multiple regions. Technological progress has improved system efficiency, reduced material usage, and enhanced overall performance, making solar desalination increasingly viable at scale. Despite these advances, high upfront investment requirements remain a key challenge compared to traditional filtration-based approaches. However, continued innovation, falling component costs, and supportive policy frameworks are gradually improving economic feasibility. Public-sector backing and long-term sustainability goals are expected to reinforce market momentum, enabling solar desalination to play a meaningful role in addressing the widening global gap between freshwater supply and demand.

The solar thermal desalination generated USD 1.6 billion in 2025 and is forecast to reach USD 4.1 billion by 2035. These systems utilize direct solar heat to drive thermal separation processes and deliver higher operational efficiency while maintaining lower energy input requirements. Their cost advantages and scalability continue to support widespread adoption across global desalination capacity.

The medium-scale systems accounted for 42% share in 2025. Growth in this segment is driven by their adaptability to varying water conditions and their ability to address localized supply requirements. Flexible system design improves deployment efficiency while strengthening water availability and supply reliability.

United States Solar Water Desalination Plant Market held 77.3% share in 2025. Increasing water stress, combined with strong public investment and renewable energy incentives, continues to accelerate deployment.
