Assuming that the implementation of this plan is on track, then it's reasonable to assume that it is at less than halfway toward its final goal during the time of the outbreak. However, in comparing the goals of the initiative to the power requirements of the colony, it seems likely that there will be enough solar powered resources available in California at least to support the power demands of the colony.
I still think that the logistics of transporting the solar resources could be an issue depending on the size of the panels or the intricacy of the technology necessary to operate them, though domestic/privately-owned units could be more beneficial.
