In this paper a stochastic model for load shifting was utilized for the purpose of investigating the potential for increased self-consumption of photovoltaic (PV) generation in households. We show the results in terms of power consumption, PV power production and solar fraction from a number of scenarios involving end-user flexibility on the order of a few percent. Simulations are performed on both an individual and an aggregate level. Results indicate that the solar fraction is only improved by a few percent both on an aggregate and individual level even for the most extreme scenarios of load shifting. The lack of substantial increase in solar fraction from imposed flexibility can partly be attributed to complementary energy use; when certain energy-demanding activities are downshifted in probability other activities are up-shifted. Another explanation for the lack of increased solar fraction is the total available fraction of flexible activities at a certain time.
