Australian researchers have found that households with solar panels could boost their returns by selling surplus power directly to their neighbors, known as peer-to-peer (P2P) energy sharing, helping to stabilize the electricity grid and negotiating a better price than retailers currently offer.

In a bid to make it more attractive and encourage the uptake of renewable energy, the Federal Government has recently implemented a $2.3 billion scheme to subsidize the installation of home batteries, but a new study shows that adding battery storage doesn't always deliver extra benefits.
