Solar Thermal Collectors Market Size, Share, Growth, Trends, and Global Industry Analysis: By Product (Concentrating, Non-Concentrating (Flat Plate, Unglazed Water Collectors, Air Collectors, Evacuated Tube, and Others) By Application (Commercial, Residential, and Industrial), and Region Forecast 2020-2031

Solar Thermal Collectors Market size was valued at US$ 30.9 billion in 2024 and is expected to reach US$ 53.3 billion by 2031, growing at a significant CAGR of 8.1% from 2025-2031. The dominant region is Asia Pacific holds the largest market share. The growth of the driven the rising energy cost as the cost of traditional energy sources continues to rise, solar thermal becomes a more attractive option for businesses and homeowners looking to reduce their energy bills, and many governments around the world are offering incentives, such as tax credits and grants, to encourage the adoption of solar thermal energy, increasing environmental concerns as people become more aware of the environmental impact of traditional energy sources, they are increasingly turning to renewable energy sources such as solar thermal. Technological advancements in solar thermal collectors are becoming more efficient and affordable, making them a more viable option for a wider range of applications.

However, the constraints of solar thermal collectors hinder the growth of the market due to the high upfront cost, and limited storage capacity, and are only effective in areas with a lot of sunshine and are also being addressed by technological advancements. With a focus on efficiency, cost reduction, and aesthetics, solar thermal collectors are becoming a more viable option for a wider range of applications. There is a significant opportunity for growth in developing markets, where there is a large demand for clean and affordable energy with several new applications for solar thermal energy emerging, such as desalination and industrial process heat, and there is a growing demand for solar thermal systems for off-grid applications, such as remote homes and businesses.
