Abstract: A simulation model for solar heating of a storage water tank, cuboid in shape, transparent honeycomb insulated at the top surface and covered with opaque insulation at all other sides is described. The validity of the model is examined by the observations made with a prototype field experiment which show good agreement. Explicit simulation results on the optimisation of honeycomb effectiveness for heat loss reduction and solar gain characteristics are presented. A honeycomb depth of 5-7.5 cm and aspect ratio of 15-20 exhibit optimum performance. Compounding of the honeycomb array with an air layer of 12 mm and the use of a selective absorber provide the benefit of added solar gain and thermal storage.
