Decoding Your Solar Quote: What Aussie Homeowners Need to Know
Thinking about joining the solar revolution? That's fantastic! But before you jump in, it's crucial to understand exactly what you're paying for. A comprehensive solar quote isn't just about the price; it's about transparency, quality, and ensuring the system meets your specific needs. Let's break down what a good solar quote should include, empowering you to make an informed decision. Read our Complete Guide for an overview of the whole solar installation process.
1. Detailed System Specifications:
Forget vague descriptions! A good quote will provide a granular breakdown of the proposed system. This includes:
- Solar Panel Details: Brand, model, wattage, and quantity of panels. Knowing the panel's specifications helps you research its efficiency and warranty. Are they a reputable brand with a proven track record?
- Inverter Details: Brand, model, and power rating of the inverter. The inverter is the brain of your system, converting DC electricity from the panels to AC electricity for your home. Again, look for reputable brands known for reliability.
- Mounting System: Description of the racking system used to secure the panels to your roof. Ensure it's designed for Australian conditions and built to withstand strong winds and corrosion.
- System Size (kW): The total capacity of the solar system, measured in kilowatts (kW). This determines how much electricity the system can generate.
2. Installation Costs & Warranty:
The quote should clearly outline all costs associated with the installation. This includes:
- Labour Costs: The cost of installing the panels, inverter, and all necessary wiring.
- Materials Costs: The cost of all hardware, wiring, and other materials used in the installation.
- Electrical Work: Any necessary electrical work, such as upgrading your switchboard or adding a dedicated solar circuit.
- Installation Warranty: A warranty covering the workmanship and installation of the system. This typically covers defects arising from faulty installation, such as disconnected cables or a leaky roof penetration. Expect a warranty of at least 5 years, but longer is better. This is separate from the product warranties for the panels and inverter.
3. STC Rebate Information:
The upfront cost of your solar system will be reduced by the STC (Small-scale Technology Certificates) rebate, a government incentive. Your quote MUST clearly state:
- The STC price assumed: STC prices fluctuate daily. A professional installer will clarify whether the quoted price has fixed the STC price. If the STC price drops between the quote and installation, will the installer absorb the cost, or will your price increase? This needs to be upfront.
- The number of STCs: Based on the system size and location.
- The rebate amount: The total value of the STC rebate, deducted from the system price.
4. Performance Estimates & Savings Projections:
A reliable installer will provide realistic estimates of the system's performance and potential savings.
- Estimated Daily/Monthly Production (kWh): A chart or table showing the estimated amount of electricity the system will generate each month. This should account for seasonal variations in sunlight.
- Roof Plan and Array Details: The quote should show a detailed roof plan indicating the placement of the solar panels, including the direction and tilt of each panel array. This demonstrates that the installer has considered the optimal panel placement for maximum energy production.
- Savings Projections: An estimate of how much money you can save on your electricity bills each year. This should be based on your current energy consumption and the system's expected output.
- Self-Consumption Ratio: The percentage of solar energy you're expected to use directly in your home, rather than exporting to the grid. A realistic self-consumption ratio is crucial for accurate savings projections. Be wary of quotes that assume 100% self-consumption, as this is rarely achievable.
5. Payment Terms & Conditions:
Understand the payment schedule and any cancellation policies.
- Deposit Amount: The amount required upfront to secure the installation.
- Payment Schedule: When the remaining balance is due.
- Cancellation Policy: What happens if you need to cancel the installation.
6. Installer Credentials & Guarantees:
- Licensing and Accreditation: Verify that the installer is licensed and accredited by relevant authorities.
- Insurance: Ensure the installer has adequate insurance coverage.
- Guarantees: Does the installer offer any performance guarantees?
Don't Be Afraid to Ask Questions!
A comprehensive solar quote should answer most of your questions, but don't hesitate to ask for clarification on anything you don't understand. A reputable installer will be happy to explain the details and address your concerns. By understanding what to look for in a solar quote, you can choose the right system and installer for your needs and enjoy the benefits of clean, affordable solar energy for years to come.
