Solar Water Desalination Plant Market: Emerging Technologies, Trends & Growth Forecast 2026-2033
The Global Solar Water Desalination Plant Market was valued at USD 2.78 billion in 2025. It is expected to reach USD 5.95 billion by 2033. That is a CAGR of 9.98% from 2026 to 2033. Solar desalination takes salt out of seawater or brackish water by using sunlight itself. The process yields quite safe drinking water indeed. The water can then be employed for drinking purposes, agriculture, and industries as well. The whole process requires two key technological systems really. Solar thermal systems capture solar energy by extracting heat from sunlight itself. Photovoltaic systems generate electrical power from sunlight to power reverse osmosis membrane systems.
