What is Solar Savings?
A solar savings calculator estimates the financial benefit of installing rooftop solar panels based on your location, system size, electricity usage patterns, and local feed-in tariff rates.
How this calculator works
The calculator uses average peak sun hours for your Australian city (ranging from 3.6 hours in Hobart to 5.5 hours in Perth) to estimate daily energy production. It then splits production between self-consumed electricity (which saves you your full retail rate, typically $0.25-0.35/kWh) and exported electricity (which earns the feed-in tariff, typically $0.04-0.08/kWh). Self-consumption is where the real savings are — the higher your self-consumption percentage, the faster the payback. Most Australian solar systems pay for themselves in 3-5 years and last 25+ years.
