The Four Ways Solar Makes Money

Before breaking down each income stream, it helps to understand that most of solar's financial return comes from cost avoidance rather than cash income. Electricity you generate and use yourself displaces grid electricity you would otherwise have bought. Displacing 30 cents per kWh of grid electricity is worth six times as much as exporting electricity at 5 cents per kWh. The financial case for solar starts with self-consumption, not export.

With that context, the four main ways solar generates a financial return in Australia are: electricity bill savings, feed-in tariff revenue, virtual power plant (VPP) participation, and battery arbitrage. Each is distinct and delivers different amounts depending on your system, usage patterns, and retailer arrangement.

1. Bill Savings: The Biggest Return

For an average Australian household using 15 to 20 kWh per day with a 6.6kW solar system, annual electricity bill savings typically range from $1,200 to $2,500. The wide range reflects different usage patterns, electricity tariff rates, and how much of the solar generation is consumed during daylight hours versus exported.

The key variable is self-consumption rate. A household where people are home during the day (retirees, families with children, home workers) might self-consume 60 to 70% of their solar generation. A household where everyone is at work and school might self-consume only 25 to 35%. The higher the self-consumption rate, the better the bill savings, because you are displacing expensive grid electricity at 28 to 40 cents per kWh rather than exporting at 4 to 10 cents.

Running high-consumption appliances during solar generation hours, scheduling dishwashers and washing machines for daytime, and heating or cooling the house in the early afternoon (pre-emptively, before evening) are all practical ways to improve self-consumption and bill savings.

2. Feed-in Tariff Revenue

Any solar electricity you generate and do not self-consume is exported to the grid. Your electricity retailer pays you a feed-in tariff (FiT) for this export, credited to your electricity account. Current FiT rates in Australia range from 4 cents to around 10 cents per kWh depending on state and retailer:

• South Australia: some retailers offer 10 to 18c/kWh through premium plans
• Victoria: minimum guaranteed FiT set by the Essential Services Commission (around 4 to 6c/kWh base; some retailers offer higher rates)
• New South Wales: no mandated minimum; typically 4 to 8c/kWh
• Queensland: no mandated minimum; typically 5 to 10c/kWh through competitive retailers
• Western Australia: Synergy's Distributed Energy Buyback Scheme (DEBS) pays 2.25c/kWh peak off-peak, 10c/kWh for shoulder

FiT revenue is worth having, but it should not be the primary motivation for solar. The arithmetic strongly favours self-consumption over export in every state.

3. Virtual Power Plant Participation

If you have a battery, you may be eligible to join a Virtual Power Plant (VPP). VPPs aggregate home batteries and allow an operator to coordinate them to provide grid services. In return, participants receive payments or bill credits.

The two main types of VPP revenue are energy arbitrage (charging batteries when electricity is cheap, discharging when expensive) and frequency control ancillary services (FCAS), where batteries help stabilise grid frequency. FCAS payments can be significant during high-volatility periods in the spot market.

Prominent VPP operators in Australia include Tesla (Tesla Energy Plan), Amber Electric, Reposit Power, and various state-based programs. Annual earnings vary considerably: $100 to $600 per year is a realistic range, with higher earners typically in states with more volatile electricity markets (South Australia, Victoria).

4. Battery Arbitrage

Beyond formal VPP programs, households on spot-price tariffs (like Amber Electric) can use their batteries to arbitrage wholesale electricity prices independently. When wholesale prices are very low (sometimes negative during high solar generation periods in the middle of the day), the battery charges. When prices spike in the evening peak, the battery discharges.

The value of arbitrage depends heavily on market conditions. In volatile electricity markets like South Australia, daily price spreads between off-peak and peak periods are large and arbitrage returns are better. In flatter markets, the returns are more modest.

AI energy management platforms (like the Heartbeat system from 1KOMMA5° or Amber's smart charging software) automate this process, removing the need for manual management. The software watches wholesale prices, weather forecasts, and household consumption patterns to optimise battery cycling for maximum financial return.

Putting It Together: Realistic Returns

A household with a 6.6kW solar system, a 10kWh battery, VPP participation, and a spot-price tariff could realistically return $1,600 to $5,000 per year in combined bill savings and earnings. At the lower end, payback on a system costing $14,000 to $20,000 is 8 to 12 years. At the higher end, payback could be 4 to 6 years. After payback, the returns continue for the remaining system life (25 years for panels, 10 to 15 years for the battery).
