Summary:This paper presents an analysis of a novel solar collector/storage system consisting of a network of pipes buried in the ground; the ground is covered with a glazed thermal trap. The heat is extracted by means of a flow of liquid in such a way that the collection temperature remains constant. An expression has been derived for the periodic rate at which heat can be retrieved to keep the collection temperature constant. Numerical calculations for a typical cold day in New Delhi predict that, for a collection temperature of 30°C and for a trap thickness of 0·03 m, the maximum possible integrated collection efficiency is 25·7 per cent.
