Your roof can earn, not just shelter
Your roof does more than keep the rain out. Paired with the right solar and battery system, it can pay you back in lower electricity bills, and sometimes in export credits too.
Your Roof Report puts a number on it: the yearly saving your roof could earn, worked out for your address.
How much could the average Australian home save?
EnergyBrain’s Rooftop Valuation Report, Australia (March 2026) modelled more than 8.4 million rooftops across 49 significant urban areas, each with an optimised 13.2 kW solar and 30 kWh battery system. It estimates:
- Average yearly saving: $3,104 per home
- Highest city average: Darwin, at $4,005 a year
- Total potential: more than $26 billion a year in electricity savings across all the rooftops analysed
Why savings differ from home to home
Four things drive what your roof could save:
- Sunlight on your roof, shaped by location, weather and shade from nearby buildings or trees
- Your roof’s condition and layout, such as material, slope and angle
- Local electricity prices
- Government incentives where you live
The guide What affects your solar savings? explains each one.
Is this only for homes that already have solar?
No. Around 2 in 5 Australian homes now have rooftop solar and about 1 in 7 have a battery, according to Renew Economy. Most households can still tap into these savings.
