Why Your Solar Feed-in Tariff Crashed to 3¢ (And How to Beat the System)
Why power companies pay pennies by day and charge a fortune at night—and how home battery storage fixes it.
Jump to
If you've recently reviewed your electricity bill and noticed solar feed-in credits between 3¢ and 5¢ per kilowatt-hour, you aren't the only one. Though power companies compensate you with minimal payments for your daytime solar energy, they immediately charge 35¢ to 40¢ as soon as the sun sets. Here’s the reason it occurred—and how a home battery reverses the equation to benefit you.
The Midday Glut vs. The Evening Spike
The drop in feed-in tariffs is due to fundamental supply and demand factors:
- The Daytime Surplus: From 11 AM to 2 PM, hundreds of thousands of rooftop installations inundate Victoria's grid while many homes remain unoccupied. This excess supply causes wholesale daytime electricity prices to plummet, resulting in retailers compensating you very little (approximately 3.3¢–5¢/kWh).
- The 35¢ Evening Trap: At 6 PM, solar production falls to nil right when everyone gets home to use air conditioning, stovetops, and gadgets. Grid demand surges, and electricity providers impose high peak charges of over 35¢ per kWh.
Selling power for 3.5¢ at noon and purchasing it again at 35¢ at night indicates that you're essentially repurchasing your own energy at a 1,000% increase.
Exploiting the Spread With a Battery
The era of making money by sending solar back to the grid is gone. The true value of solar now lies entirely in self-consumption—keeping every unit of power your roof makes inside your home.
| Action | Without Battery (Export Model) | With Battery (Self-Consumption) |
|---|---|---|
| Daytime Excess | Export 10 kWh @ 3.5¢ credit (+$0.35) | Store 10 kWh in battery ($0.00) |
| Evening Demand | Buy 10 kWh @ 35¢ (-$3.50) | Draw 10 kWh from battery ($0.00) |
| Daily Cost | -$3.15 out of pocket | $0.00 out of pocket |
Instead of making 35 cents exporting power, you bank the 10 kWh to eliminate a $3.50 night-time bill. Over a year, that single daily cycle saves over $1,100.
Stop Donating Energy to the Grid
Low feed-in tariffs don't mean solar is broken; they mean the rules have changed. A solar battery eliminates the middleman, ensuring the clean energy your panels produce powers your home rather than padding your retailer's profits.
