“Flat Plate Collectors Will Dominate the Market in Coming Years

Based on the collector type, the solar thermal market is segmented into an evacuated tube collector, flat plate collector, unglazed water collector, and air collector. Out of the given type of collectors, the evacuated tube collectors segment is occupying a lion share in the world market, owing to its operational advantages over the other type of collectors. As the demand for solar thermal is expanding in Europe which is one of the leading regions, the market share of flat plate collectors segment has also risen owing to their maximum utilization. The technological advancements brought in the flat plate collectors to increase their efficiency has been one of the reasons for high solar thermal market growth. Air collectors occupy a minimal solar thermal market share in the market as they are only deployed for some specific use and have low operational efficiency.  

By Type of System Analysis

“Trend of Deployment of Thermosiphon Systems Will Be Continued

Based on the type of system, the solar thermal market can be majorly divided into thermosiphon solar heating systems, and pumped solar heating system. In recent years the deployment of thermosiphon systems has been preferred over the pumped solar heating systems. In 2017, among the newly installed solar thermal systems, more than half of the installations were of thermosiphon systems.  These systems are preferred in regions of warm climate that include Africa, South America, Europe, and countries in the Middle East regions. Here in these regions, these systems are used with evacuated type collectors and are also used with the flat plate collectors for hot water applications in other regions.  

By Application Analysis

“Application of Solar Thermal Power Varies Significantly Based on Installation Region”

Based on application, the solar thermal market can be segmented into domestic hot water systems, large DHW systems, solar combi systems, swimming pool heating, and others. The applications of solar thermal systems vary significantly from region to region. In China, which occupies a significant solar thermal energy market share, solar thermal systems are majorly deployed for domestic hot water systems, whereas in the Middle East & Africa, these are majorly used for large DHW systems. On the other side, solar thermal systems in North America are prominently used for swimming pool applications. Thus, depending upon the specific requirement in a particular region, solar thermal energy trend finds its application and this is further expected to be continued in the forecast period.  


Geographically, the market has been analyzed across five major regions, namely North America, Asia Pacific, Europe, Latin America, and the Middle East & Africa. Among these, Asia Pacific is projected to be the dominating region in the forecast period. The primary reasons contributing to the growth are the rising energy demand in the region, further attributed to the increasing population and urbanization witnessed in recent years. Also, the green energy targets being looked upon by countries have increased the deployment rate of solar power in the region. Currently, China is the market leader both regionally and globally, and this solar thermal power market trend is set to continue with rising investment being witnessed for solar power. The presence of key market players will also have a positive impact on the regional solar thermal energy market growth.

Solar thermal energy generation involves energy being generated in a substantial amount, which is then distributed for different applications. The system may consist of solar photovoltaic that functions as a single unit. Also, it can be made up of mirrors that are used to focus the sunlight on a particular point, where the energy from sun rays is used for generating heat. This energy is then used for diverse applications, like district heating, district cooling, swimming pool heating, hot water systems, combi systems and other applications.

Various types of solar panels can be used in solar thermal power plants; the main difference between the type of technology stands between the collectors that are being used. These collectors can be water collectors, air collectors, glazed collectors, or unglazed collectors.
