Solar District Heating Market Size

Solar District Heating Market size was valued at USD 4.9 billion in 2022 and is projected to grow at 8.5% CAGR from 2023 to 2032. It is a type of heating system that uses solar energy to provide heat for a large number of buildings within a specific district or community. It involves the use of solar collectors, which are typically installed on rooftops or in fields, to collect solar radiation and convert it into heat. The heat produced by the solar collectors is then transferred to a heat storage system, which can be used to provide heating solutions to buildings within the district. This can be done through a network of pipes and heat exchangers, which distribute the heat to different buildings as needed.

COVID-19 Impact

The key challenge faced across the industry was the disruption to supply chains, which impacted the availability of solar thermal panels and other components needed for solar district heating market. This led to delays in projects and increased costs for others. In addition, the pandemic led to a decrease in energy demand in some areas, particularly in commercial and industrial sectors that were temporarily shut down or operating at reduced capacity. This reduced demand for heating, which impacted the economics of some solar district heating projects. However, increasing policy support, need to reduce greenhouse gas emissions along with transition to renewable energy will propel the market growth.
