Small scale sorption chillers are now commercially available, but there are several non-technical barriers which can bother a smooth market entry:
Combined solar heating & cooling needs high effort in design stage, which is not affordable for small applications
Small scale sorption chillers are at the moment expensive due to low production numbers
Small scale combined solar heating & cooling is not enough known by key actors, such as installers and planners on the one side as well as public authorities and consumers on the other side
