OPTIMAL CAPACITY OF AREAL PV FOR GER WITH ELECTRIC THERMAL STORAGE IN ULAANBAATAR

Abstract

To reduce air pollution in Ulaanbaatar city, we need to properly penetrate the advanced technologies of energy generation and heating devices into the existing types of residences. Therefore, we are testing electric thermal storage (ETS) heater and an insulation improved Ger (yurt) since October of 2017. This study presents the optimal PV capacity for supplying a Ger with ETS as well as without ETS. The 45o, and 60o tilt angles, in the period of winter, are good for electric demand with ETS. The optimal PV rated capacities, for typical and night-time ETS heating demand, are 2-4 kWp while 5-7 kWp are suitable for demand with day-time heating.
