Yes--I looked at batteries, but I decided that with net metering I did not need them. With net metering, the grid basically acts as your battery--during periods when you generate more than you use, the excess power is sent to other homes and your electric meter spins backwards, reducing your electric bill. At night, your electricity is supplied by fossil fuel. Adding a battery keeps all the juice at your house for nighttime use, but the grid is paying you a pretty good rate for the electricity, so the battery does not pay for itself the way the panels do.
One great advantage of the batteries is backup power for outages.
There are some limits on net metering that a local installer can provide. For those in Mass--the net metering deal is going to become less attractive for systems installed after June, and it takes a couple of months to get the system done. So now is a good time to call.
