Resource Indicators Used for Solar Photovoltaic Plants in Uzbekistan Part 1

Abstract

The annual supply of total solar irradiation (SI) to the surface of a randomly oriented photovoltaic panel (PVP) is considered; on this basis, the optimal horizontal tilt for seasonal or annual use is found. A flow diagram is proposed for determining the global total irradiation (GTI) on the surface of PVPs installed in variously oriented positions. Surkhandarya region is considered as an example. The actinometric findings obtained from the Sherabad station, as well as the PVP test results, are provided.
