Net Metering vs Gross Metering: What's the Difference? Complete Australian Guide
Understanding the difference between net metering and gross metering is crucial for anyone considering solar panels or trying to maximize their existing solar system's financial benefits. These two metering approaches fundamentally change how you're billed for electricity and can significantly impact your long-term savings from solar energy.
While Australia primarily uses net metering systems today, understanding both approaches helps you interpret your solar electricity bill, make informed decisions about system sizing, and choose the most suitable electricity plan. Tools like Huglo can help you compare electricity plans that work best with your specific metering setup, while professional solar installers ensure your system is optimized for your billing arrangement.
What is Net Metering?
Net metering is a billing arrangement that measures the difference between electricity consumed from the grid and electricity exported to the grid, crediting you only for the surplus energy your solar system produces beyond your immediate consumption.
How Net Metering Works
Bidirectional Energy Measurement
- Import measurement: Tracks electricity drawn from the grid when your solar system isn't producing enough
- Export measurement: Records excess solar electricity sent back to the grid
- Net calculation: Your bill shows the difference between imports and exports
- Single connection point: One meter handles both incoming and outgoing electricity flows
Real-Time Energy Balance
- Immediate consumption: Solar power used instantly by your household doesn't register on your bill
- Excess export: Only surplus solar energy after meeting immediate needs is exported
- Grid dependence: When solar production is insufficient, you automatically draw from the grid
- Seamless operation: System switches between solar, battery (if installed), and grid power automatically
Billing Under Net Metering
- Net usage charges: You pay for grid electricity minus any solar exports
- Feed-in tariff credits: Receive credits for excess solar exported to the grid
- Supply charges: Daily connection fees apply regardless of your net energy position
- Time-of-use impact: Export timing affects credit values under time-of-use tariffs
Net Metering Benefits
Financial Advantages
- Simplified billing: Easier to understand with clear import/export distinctions
- Direct offset: Solar production directly reduces grid consumption charges
- Lower administrative costs: Single meter reduces infrastructure and maintenance costs
- Flexible consumption: No penalty for using solar power as it's generated
System Optimization
- Right-sizing encouragement: Systems sized to match household consumption are most cost-effective
- Load shifting benefits: Moving consumption to solar generation hours maximizes savings
- Battery storage compatibility: Works well with battery systems for enhanced optimization
- Grid stability: Reduces overall grid stress by encouraging local consumption
Net metering is the standard approach used across Australia today, making it essential to understand when evaluating solar investments and electricity plans.
What is Gross Metering?
Gross metering is a billing system that separately measures all electricity consumed from the grid and all electricity exported to the grid, treating solar generation as a completely separate transaction from household consumption.
How Gross Metering Works
Separate Measurement Systems
- Consumption meter: Measures all electricity used by your household, regardless of solar production
- Generation meter: Records all electricity produced by your solar system
- Independent billing: Consumption and generation are billed as separate line items
- Total solar export: All solar production is considered as export to the grid
Complete Solar Export Model
- No direct self-consumption: Solar power doesn't directly offset household usage on your bill
- Grid dependency for all consumption: Household electricity needs are met entirely from the grid on paper
- Full solar export: Every kilowatt-hour of solar production is exported and credited
- Two-way energy flow: Clear separation between energy purchased and energy sold
Billing Under Gross Metering
- Full consumption charges: Pay standard rates for all electricity used by your household
- Full generation credits: Receive feed-in tariff payments for all solar electricity produced
- Separate calculations: Consumption costs and generation income are calculated independently
- Feed-in tariff dependence: System economics heavily dependent on export rate levels
Gross Metering Characteristics
Financial Structure
- Premium feed-in rates: Historically offered higher rates to encourage solar adoption
- Consumption independence: Solar generation doesn't directly reduce consumption charges
- Rate differential importance: Economics depend on difference between consumption and feed-in rates
- Cash flow benefits: Can provide positive cash flow if feed-in rates exceed consumption costs
System Design Implications
- Maximum generation focus: Larger systems generate more income regardless of household usage
- Consumption timing irrelevant: When you use electricity doesn't affect solar economics
- Grid interaction: All energy flows through the grid, increasing transmission losses
- Administrative complexity: More complex billing with separate consumption and generation accounts
While gross metering was used in some early Australian solar programs, it has largely been replaced by net metering due to cost and efficiency considerations.
Key Differences Between Net and Gross Metering
Understanding the fundamental differences between these metering approaches helps you optimize your solar investment and choose appropriate electricity plans:
Measurement and Billing Differences
Energy Flow Accounting
Net Metering:
- Measures only the difference between consumption and generation
- Solar power used immediately doesn't appear on electricity bills
- Bills show net grid consumption after solar offset
- Simpler billing with fewer line items
Gross Metering:
- Measures consumption and generation separately and completely
- All household electricity usage appears as grid consumption
- All solar production appears as grid export
- More complex billing with separate consumption and generation sections
Financial Impact Calculation
Net Metering:
- Savings = (Solar self-consumption × retail rate) + (Solar export × feed-in rate)
- Direct reduction in grid consumption charges
- Feed-in tariff applies only to excess solar production
- Economics favor matching solar production to consumption patterns
Gross Metering:
- Income = (Total solar production × feed-in rate) - (Total consumption × retail rate)
- No direct consumption offset from solar production
- Feed-in tariff applies to all solar production
- Economics favor maximum solar generation regardless of consumption timing
Economic Implications
System Sizing Considerations
Net Metering:
- Optimal sizing: Systems sized to match annual or daily consumption typically most cost-effective
- Diminishing returns: Oversized systems provide lower returns due to reduced feed-in rates

Gross Metering:
- Maximum generation focus: Larger systems provide higher absolute returns
- Size independence: System economics less dependent on consumption patterns
- Feed-in rate critical: System viability depends heavily on feed-in tariff levels
- Consumption timing irrelevant: When you use electricity doesn't affect solar system returns
Cash Flow and Returns
Net Metering:
- Bill reduction focus: Primary benefit is reduced electricity bills rather than income
- Gradual savings: Benefits accumulate through reduced grid consumption over time
- Rate escalation protection: Savings increase as electricity prices rise
- Self-consumption premium: Direct consumption typically more valuable than export
Gross Metering:
- Income generation: Can generate positive cash flow if feed-in rates are sufficiently high
- Feed-in rate dependence: Returns directly tied to export payment levels
- Rate risk: Vulnerable to reductions in feed-in tariff rates
- Grid price independence: Returns less affected by changes in retail electricity rates
System Operation Differences
