We can here talk about more or less conservative hypothesis, ie hypothesis more or less "careful", in order for the battries to be always charged in winter. We notice that whatever the hypothesis to satisfy in a continuous way the needs, includin winter, we have overproduction in summer. It is then relavant to use overproduction reuse system in absence of grid in which we can inject the surplus (for example by hyrdolyzing water to produce hydrogen and then transform hydrogen in methane, cf scenario negawatt 2011).
