Photovoltaics (solar electricity) and plug in hybrids can be a boon for overburdened city electric infrastructure. We have already seen on both coasts how abundant summer sunshine has fostered blackouts and other breakdowns of the city electric grids in NY and CA.

A vehicle to grid hybrid parked under a solar array can contribute solar power to the grid. Because the hybrid has batteries, the momentary drop in solar output caused by a passing cloud is of no concern. This makes the solar power much better suited for the electric utility.

Besides the tremendous benefit of preventing blackouts, the driver gets a cooler car from the shade of the solar array. This also saves fuel as the vehicle air conditioner does not have as much work to do.
