Project Sunroof
Putting solar panels on roofs may have made sense when PV was expensive and the component cost was a big multiple.But now? Far better to just stick a bunch of them in the desert where they can be inexpensively installed and maintained -- pass the savings along to consumers. This saves a lot of pain when people "invest" a bunch of money in labor intensive installations, only to figure out the difference between wholesale and consumer rates when they cannot sell power back to the grid at $.20/kWh.At a macro scale, there is no reason to incentivize residential solar, other than "feels."
