Reading Your Electricity Bill with Solar
Understanding your solar electricity bill is essential for managing your energy consumption and maximizing the benefits of your solar system.
This quick guide covers the essentials you need to know, including a detailed breakdown of charges and credits to common terms like kilowatt-hours (kWh), Feed-in Tariff (FiT), net metering, peak and off-peak rates, supply charges, and environmental fees.
By understanding these components, you can gain better insight into your energy consumption, monitor your savings, and discover ways to reduce costs.
Whether you’re a new solar customer or looking to get more out of your existing system, this guide provides the clarity you need to understand and manage your solar electricity costs effectively.
Key Components of Your Bill
- Account Summary
- Previous Balance: The unpaid amount carried over from your last bill.
- Payments and Adjustments: Lists payments made and any credits or adjustments.
- Current Charges: The total amount due for the current billing period, including all usage charges and fees.
- Usage and Charges
- Solar Export: The amount of electricity generated by your solar panels and exported to the grid, measured in kilowatt-hours (kWh). You receive a credit for this, often referred to as the Feed-in Tariff (FiT).
- Grid Usage: The electricity drawn from the grid when your solar system does not meet your needs. This usage is also measured in kWh and is billed at your retail rate. In Queensland, the current rate ranges from approximately 25 to 35 cents per kWh, depending on your plan and electricity provider.
- Feed-in Tariff (FiT)
- The rate at which you are compensated for the electricity your solar system exports to the grid. This rate varies by energy provider and your specific contract. Typically, the Feed-in Tariff is around 6-12 cents a kWh, so it is important to shop around and find the best deal.
- Supply Charges
- A daily fixed charge for maintaining your connection to the electricity grid, regardless of your usage. It covers infrastructure and maintenance costs. In Queensland, this rate usually falls between 90 and 140 cents per day.
- Additional Charges
- Environmental Charges: Fees for government initiatives supporting renewable energy, such as the Renewable Energy Target (RET).
- Metering Charges: Costs associated with the maintenance and reading of your electricity meter.
- GST (Goods and Services Tax)
- A 10% tax applied to most goods and services in Australia, including your electricity charges.

Common Terms Explained
- kW (Kilowatt): A unit of power that represents the rate at which electricity is used or generated. For example, a 5kW solar system can generate 5 kilowatts of power under optimal conditions.
- kWh (Kilowatt-hour): A unit of energy that measures electricity usage or production over time. One kW-h represents the amount of energy used if a 1kW appliance runs for one hour.
- Peak and Off-Peak Rates:
- Peak Rates: Higher charges applied during times of high electricity demand, typically during the day and early evening.
- Off-Peak Rates: Lower charges during periods of low demand, often overnight or early morning.
- Net Metering: A billing mechanism that credits solar energy system owners for the electricity they add to the grid. With net metering, the solar energy generated by a solar power is first used to meet the energy needs of the household. If the system produces more energy than the household consumes, the excess energy is exported to the electricity grid. The homeowner receives a credit or payment, known as a “feed-in tariff,” for this surplus energy.
- Consumption: The total amount of electricity used by your household, typically measured in kWh. It includes both the energy generated by your solar system and the energy drawn from the grid.
- Demand Charge: A fee based on the highest amount of power you draw from the grid during a specific period. It reflects the maximum demand your household places on the electricity network.
- Fixed Charge, Supply Charges or Service Charges: A set fee on your bill that covers the cost of maintaining your electricity account and the infrastructure required to deliver energy to your home. This charge is independent of your electricity usage.
- Variable Charge: The portion of your bill that varies based on the amount of electricity you use. It includes the cost per kWh consumed.
- Rebate: A refund or discount on your bill, often provided by the government or your energy retailer. Rebates can be offered for various reasons, such as energy efficiency improvements or participation in specific programs.
- Solar Credits: Credits you receive on your bill for the electricity generated by your solar system and exported to the grid. These are typically represented as a negative charge, reducing your total bill amount.
- Smart Meter: An advanced meter that records electricity usage in intervals (usually half-hourly) and communicates this information to your energy provider. Smart meters provide more accurate billing and allow for dynamic pricing plans.
Considerations for Solar Users
After installing solar, it’s important to closely monitor your electricity bill to ensure you’re maximizing the benefits of your solar power system. If you notice that your grid consumption hasn’t decreased as expected after solar installation, consider these possibilities:
Meter Installation Delay: There might have been a delay between installing your solar system and configuring your solar meter. Your system legally cannot be turned on before the meter is ready.
System Issues: Your system might not be functioning correctly. Using a solar monitoring system can help you identify the problem, showing you the exact day your system started producing energy and the overall health of your system.
Increased Consumption: You might have unknowingly increased your energy use during non-solar hours, negating the savings from your solar system.
Tips for Maximizing Solar Benefits
Check Your Bill: Always ensure that the credits for your solar exports are correctly applied and that the rates match what you were promised by your electricity retailer.
Understand Your Tariff: Be aware of your electricity plan, especially if your retailer suggests switching to a Time-of-Use (ToU) tariff. ToU tariffs are often not beneficial for solar owners, so stick with a plan that works best for your solar production.
Use Monitoring Tools: Your inverter may come with an app for monitoring your solar production and consumption in real-time. Alternatively, consider using a dedicated solar monitoring system such as Solar Analytics. These tools help ensure that your solar system is performing optimally and allow you to maximize your savings by keeping a close eye on your energy usage.
By staying informed and actively monitoring your electricity bill, you can ensure that your solar power system is delivering the savings you expect.
