A computer analysis of solar heating has been performed for Turkey. Results are presented for two prototype buildings using either fuel-oil or coal under different heating loads in three climatic regions (Antalya, Ankara and Kars). Cumulative cost flows are compared for the life-cycle present value technique. Optimum design magnitudes are determined for maximum life-cycle savings. The payback period for capital invested in a solar system, internal rate of return, and total savings are found for the optimum conditions. Variations of system performance are estimated. The effects of collector slope, proportionate storage tank volume, heat-exchanger parameters, and the design load on system performance are studied. Finally the economics of solar heating in Turkey are discussed and recommendations made for increased utilization of solar energy.
