Exclusive: Solar Citizens says since the 2012-13 financial year, rooftop solar owners have saved about $1bn on their household bills each year

Australian households and small businesses have invested more than $1bn a year in rooftop solar over the past five years, spending a total of almost $8bn since 2007, new calculations show.

In its latest State of Solar report, Solar Citizens - which campaigns for, and represents the interests of, solar owners - has for the first time estimated Australian's out-of-pocket investment in rooftop solar, how much money it has saved consumers, and how much carbon it has abated.
