In this report we discuss the present situation of solar water heating for
domestic supplies in Turkey and give the results of a computer analysis for
nine distinct regions. The analyses are carried out for four typical days
of the four seasons and also on a monthly base. The results show that detai
led initial work must be carried out before installing the system to determ
ine the optimized collector area. Such analysis can provide efficient using
of the Sun's energy as well as economical benefits in the initial investme
nts and long term utilization. (C) 1999 Elsevier Science Ltd. All rights re
