Solar district heating systems utilize solar energy to supply heat to multiple buildings within a specific community or district. These systems incorporate solar collectors, often installed on rooftops or in open fields, to harness solar radiation and convert it into thermal energy. The captured heat is stored in a thermal storage system, allowing for continuous and efficient heat distribution through a network of pipes and heat exchangers. The infrastructure provides heating to various buildings along with representing a sustainable and cost-effective solution for large-scale heating demands while reducing reliance on conventional energy sources.
