This study analyses technological and social barriers against the use of solar water heating (SWH) systems and compile the best practice to select and take decisions on the design of a SWH system. Possible barriers are divided into 5 groups (hydraulic installations, entitlement to sunshine, current regulation, community collaboration, new businesses), as well as best practice (concept selection, equipment selection, control systems, operation and maintenance, general considerations).
The document highlights how the main barriers to the development of SWH are social, while aware community collaboration is fundamental for the best use of SWH systems.
