In Serbia, it is customary to use electrical energy for heating of domestic hot water (DHW). As around 70% of electrical energy is produced by using coal with high greenhouse emission, it is beneficial to environment to use solar energy for heating of DHW in solar DHW system (SDHWS). During SDHWS operation, different SDHWSs generate different amounts of heat from solar energy, obtain different amounts of avoided electrical energy, avoided exergy, and avoided fossil energy. These investigations use computer code EnergyPlus. The used weather data are from the meteorological station.
In this paper, a use of Hooke-Jeeves algorithm is reported to obtain the maximum amounts these of performances for different SDHWS use as a function of number of optimum tilt positions of the solar collector in SDHWS during year for Belgrade, in Serbia.
