Boffins looking into the Australian solar energy ecosystem say that sharing really is caring – and potentially profitable when homes with solar panels can sell their excess energy to neighbors at a preferential rate.

"Under current conditions in Victoria, the feed-in tariff is less than 5 cents per kilowatt hour, while the retail price is around 28 cents. Selling surplus PV [photovoltaic] energy directly to neighbors at a mutually agreed price in between can be more profitable for solar householders and still cheaper for buyer," lead author Dr Kevin Wang, of the University of South Australia, explained in a post-publication statement outlining the study's findings.

"Our modelling revealed that under current conditions, P2P energy sharing coupled with a 10 kWh battery could deliver the hi
