Game-Changing Energy Storage

The economics of residential solar are currently dependent on two things. The first is the number of kilowatt-hours (kWh) a homeowner's panels produce and send back, a.k.a., 'backfeed,' to the electric grid during the day, such that when they use power at night, the kWhs from the grid are deducted from what they sent back earlier. (This does require, however, that the value of the power sent back during the day is the same or nearly the same as the power used at night.) The second, and typically smaller phenomenon, is the power the panels produce that appliances in the home use before it can be sent back.

Unfortunately, this comes with limitations. The first is the total cumulative amount of kWhs the panels produce can't be more than the homeowner uses in a year. The second limitation is when there is a power outage on the grid, the solar panels connected to it in that location have to shut down. This is a safety feature to protect utility workers trying to restore it, but it also means even with a way to make their own power, homeowners are stuck in the dark. (Backup generators are a different situation, but, sticking with the example of solar, this is the case.) Third, the power lines that distribute power from local substations have a capacity limit as to how much solar power can be backfed. At present, this means there are only so many houses on a distribution "circuit" that can have solar before it can't accept more. It's an infrastructure issue that limits the market and puts accessing cheaper energy on a first-come, first-served basis.

But, what if there was a way for every house to have solar panels AND use all the power they generate without needing the grid to make it economical? (And safely keep the lights on if the grid goes down, should the homeowner so choose?)
