Assessing the value of rooftop solar across Australia
Australia
National Average Savings
$3,104
World-leading solar adoption
With over 33% of suitable households powered by rooftop PV, Australia is world-leading in decentralised energy, reducing reliance on the grid and transforming rooftops into a distributed national asset.
Sydney
Annual Bill Savings
$3,280
Essential cost mitigation measure
While Sydney's solar irradiance is moderate, their high electricity costs make solar essential. Every kWh generated represents savings and resilience.
Brisbane
Strong East Coast Performer
3.98 Years
High investment potential
Brisbane stands out with a payback period of less than 4 years, making it a strong location for investing in solar.
Darwin
Shortest Payback Period
3.14 Years
Best return on investment
Generous rebates and average investment costs make Darwin's payback on solar the fastest out of any Significant Urban Area, offering the best returns over 10 and 20 years.
Dubbo
Highest Average Subsidies
$12,623
Generous policy support
Driven by fringe-of grid constraints, local installations favour oversized PV and storage systems, capturing the highest STC incentives in the country.
Melbourne
Mega Household Market
$5.59 billion annual savings
Largest market size nationally
With a massive base of almost 2 million households, Melbourne offers unparalled market value, driving an estimated total annual bill savings of $5.59 billion.
