For any arbitrary variety V , the degree dp(V ) of V with respect to proper hypersubstitutions was introduced in [6]. This degree of any variety of bands was determined in [4]. In this paper we characterize the universe of the free algebra of each solid variety of semirings and from this we derive the degree dp(V ) if V is any solid variety of semirings.
