PHEV > BEV becuz...
The combination of rooftop solar panels with PHEVs is a better match than with BEVs because the battery pack is 1/3 the size. The household with this combo gains the means to more closely monitor (and conserve) household energy consumption, and gains the choice whether to drive or cut utility bills.
Even if a PHEV (Plug-in Hybrid EV) affords only a 10-20 mile driving range on the battery, this limitation leads to driving less whereby more routine trips become possible without having to drive. Walking, bicycling and mass transit, (fundmental travel modes more energy efficient than an electric car), become more viable travel alternatives.
PHEVs offer many additional benefits/advantages over BEVs, but these conservation-oriented points are most important. We drive too much and there's no getting around that with a battery-electric or fuel cell car that allows us to pretend we can continue the bad habit.
