  In this work we consider a class of stochastic parabolic equations with
singular space depending potential, random driving force and random initial
condition. For the analysis of these equations we combine the chaos expansion
method from the white noise analysis and the concept of very weak solutions.
For given stochastic parabolic equation we introduce the notion of a stochastic
very weak solution, prove the existence and uniqueness of the very weak
solution to corresponding stochastic initial value problem and show its
independence of a regularization on given singular potential. In addition, the
consistency of a stochastic very weak solution with a stochastic weak solution
is shown.
