They are widely installed in residential buildings for heating water used for bathing, cooking, and cleaning purposes. They are also utilized for producing electricity on a large scale in thermal power plants.

At present, rising concerns about the over-expenditure of natural resources are propelling the growth of the market. Besides this, governing agencies of various countries are encouraging commercial and industrial sectors to shift to renewable energy sources to prevent the excessive consumption of electricity. In addition, the growing utilization of sustainable energy sources to fulfill rising energy demands across the globe is offering a favorable market outlook. Apart from this, the increasing investment in public, commercial, industrial, and infrastructure projects is supporting the growth of the market. Additionally, the rising awareness about climate change and global warming is strengthening the growth of the market. Moreover, the increasing installation of heating, ventilation, and air conditioning (HVAC) setups in commercial and residential establishments to control temperature, humidity, and air quality is bolstering the growth of the market.

Solar Thermal Collectors Market Trends/Drivers

Rising demand for clean energy sources stimulating market growth

At present, there is an increase in the demand for clean and renewable energy sources around the world due to the rising environmental awareness among the masses. In addition, rising levels of pollution caused by burning fossil fuels and emissions of harmful exhausts from industries and automobiles are increasing the adoption of sustainable energy sources. Furthermore, as non-renewable energy sources are causing unrepairable damage to the environment and are responsible for inducing climate change and global warming, the demand for various eco-friendly energy sources, such as solar energy, is growing. Solar energy is profusely available and can be easily converted into other forms of energy with the help of solar thermal collectors.

Increasing construction of smart cities catalyzing demand for solar thermal collectors

Smart cities depend on information and communication technology (ICT) to enhance operational efficiency and offer a better quality of life to people. Their primary agenda is to optimize city functions and facilitate economic growth while utilizing smart technology and data analysis. Smart cities also improve public health and maintain public safety. As a result, governing agencies of various countries are undertaking initiatives to build smart cities, which is catalyzing the demand for sustainable energy sources. They are installing solar thermal collectors at various locations within smart cities and encouraging individual households to rely on solar energy rather than conventional energy sources to minimize the levels of pollution and lead life sustainably.

Rising depletion of non-renewable natural resources augmenting market growth

Non-renewable natural resources are various raw materials or substances which are formed within nature in limited quantities without the help of mankind. They comprise a wide variety of materials that are used for generating power or energy, such as petroleum, coal, and natural gas. These materials are not replenished with the speed at which they are consumed for generating power. Hence shifting to sustainable and cleaner energy sources is necessary to stop the over-expenditure and depletion of various non-renewable natural resources. Sustainable energy sources, such as solar energy, which are abundantly available in the environment, are gaining popularity as a cleaner alternative to non-renewable energy sources. Furthermore, solar energy can be collected with the help of solar thermal collectors and converted into electrical power without causing harm to the environment.

Solar Thermal Collectors Industry Segmentation

IMARC Group provides an analysis of the key trends in each segment of the global solar thermal collectors market report, along with forecasts at the global, regional, and country levels for 2025-2033. Our report has categorized the market based on product and application.

Breakup by Product:

• Concentrating
• Non-Concentrating
  • Flat Plate
  • Evacuated Tube
  • Unglazed Water Collectors
  • Air Collectors
     

Non-concentrating (flat plate, evacuated tube, unglazed water collectors, and air collectors) represents the most popular solar thermal collectors

The report has provided a detailed breakup and analysis of the solar thermal collectors market based on the product. This includes concentrating and non-concentrating (flat plate, evacuated tube, unglazed water collectors, and air collectors). According to the report, non-concentrating (flat plate, evacuated tube, unglazed water collectors, and air collectors) represented the largest segment.

Non-concentrating solar thermal collectors are solar energy systems consisting of an interceptor and absorber of similar size. They comprise a flat plate, evacuated tube, unglazed, water collectors and air collectors, which are used for various purposes, including heating water in residential buildings, heating swimming pool water, and heating water for industrial applications. Furthermore, they can use direct beams of solar radiation under numerous angles and diffuse radiation scattered by atmospheric influences.

Concentrating solar thermal collectors comprise a bigger interceptor than the absorber and utilize mirrors to reflect and concentrate sunlight onto a receiver. Besides this, they absorb solar radiation and transform it into some other form of energy via the receiver. They store energy via thermal energy technologies, making power available even when there is not enough sunlight. They are flexible or dispatchable options for providing clean and renewable energy.

Breakup by Application:

• Commercial
