In Hinduism, Surya [the Supreme Light] is the chief solar deity. The term Surya also refering to the Sun, in general. Surya has hair and arms of gold. He presides over "Ravi-waar" or Sunday.
In Hindu religious literature, Surya is notably mentioned as the visible form of God that one can see every day. Furthermore, Shaivites and Vaishnavas often regard Surya as an aspect of Shiva and Vishnu, respectively.
The presence of Ganesha, son of Shiva on one side leave to think that we are in a Shivaist representation of Surya.
