Building codes and renewable energy mandates (for example, requiring a portion of building heat to come from renewable sources) also propel the market. In the commercial sector, green building certifications and consumer preferences for sustainable businesses are encouraging hotels, hospitals, and other facilities to utilize solar thermal for water heating and space conditioning. These policy and market signals collectively stimulate investment across the solar thermal industry.

Regional Insights

The solar thermal market is truly global, but growth and adoption rates vary by region due to climate, policy, and economic factors. Asia-Pacific is the indisputable leader in solar thermal deployment, accounting for the largest share of global installations and market revenue. In particular, China has been the dominant market – at one point representing well over half of worldwide solar thermal capacity, thanks to decades of government promotion of residential solar water heaters. China’s market growth has moderated recently as urban markets approach saturation, but it continues to install vast numbers of systems and is pivoting toward larger-scale applications (like solar district heating and industrial projects). Other Asia-Pacific countries such as India are also significant contributors, with India promoting solar thermal for both homes and factories as part of its renewable energy strategy. Overall, Asia-Pacific is estimated to hold nearly half of global market share, and it remains a region of high potential given its sunny climate zones and expanding energy needs.

Europe holds the second-largest regional market share, roughly around one-fifth of the global solar thermal market. European countries have a strong policy push for renewable heating in pursuit of climate goals and energy independence. Nations like Germany, Greece, Spain, and Turkey have longstanding solar thermal markets for water and space heating. In recent years, Europe’s growth has been especially notable in solar district heating – large centralized solar thermal farms that supply heat to multiple buildings or even whole communities. Countries in Northern and Central Europe (including Denmark, Sweden, Germany, Austria) are investing in these district systems, often integrating them with seasonal thermal storage to capture summer sun for winter use. Additionally, the European Union’s directives for renewable energy in heating (and initiatives like the Green Deal) are boosting adoption across both residential and commercial segments. Even regions with moderate climates, such as the UK and the Netherlands, are seeing increased interest as technology improves and as policies (like renewable heat incentives) make solar thermal more cost-competitive.

North America is another important region with growing solar thermal activity, though it currently trails Asia and Europe in market size. In the United States and Canada, solar thermal has historically been a smaller niche (with some popularity in sun-rich states like California, Arizona, and Florida for pool heating and domestic hot water). However, the landscape is changing with new incentives: for instance, the U.S. offers an Investment Tax Credit (ITC) for solar thermal installations, and various states have introduced rebates and requirements for solar heating in certain building types. These measures, along with rising consumer awareness of renewable heating and higher utility costs, are driving new demand. North America’s market is expected to see a healthy uptick in the forecast period, focusing on both commercial applications (such as hotels, hospitals, multifamily housing adopting solar thermal) and niche industrial uses (like agriculture and food processing facilities). The region’s share of the global market is likely to rise gradually as these projects multiply, though it remains behind Europe and Asia-Pacific in the near term.

Latin America and the Middle East & Africa (MEA), while currently smaller contributors in terms of market percentage, represent high-growth regions for solar thermal. In Latin America, countries such as Brazil and Mexico have accelerated adoption in recent years. Brazil, for example, has seen double-digit growth in solar water heater installations, driven by efforts to localize manufacturing and reduce electricity strain. Mexico’s combination of high solar irradiance and supportive policies at federal and state levels has led to a burgeoning market, with solar thermal increasingly used in both homes and businesses (often in hybrid setups with heat pumps to maximize efficiency). Other nations in Latin America (Chile, Argentina, etc.) are also exploring solar thermal for industrial process heat and rural development.

In the Middle East & Africa, the abundant sunshine makes solar thermal extremely promising. Several Middle Eastern countries (like Saudi Arabia, United Arab Emirates) are investing in large concentrated solar thermal power plants and water desalination projects using solar heat, as part of diversifying their energy mix. At the same time, in regions of Africa and South Asia, simple thermosiphon solar water heaters are a cost-effective solution for communities without reliable electricity or gas infrastructure. MEA’s overall market share is still modest, but pilot projects and new government initiatives indicate a strong growth curve ahead. For instance, South Africa and Kenya have launched programs to install solar thermal systems in industrial parks and institutions to cut fuel costs. Across these emerging markets, the combination of high solar resources and growing energy demand sets the stage for solar thermal technology to leapfrog traditional heating methods.
