  Solar Panels: These are the heart of the system, capturing sunlight and converting it into direct current (DC) electricity. Modern panels are highly efficient, even in Australia’s diverse weather conditions.
  


• 
  Inverter: The inverter is the brain of the system, transforming the DC electricity generated by the panels into alternating current (AC), which powers your home appliances.
  


• 
  Solar Battery (Optional): A solar battery stores excess energy generated during the day for use at night or during peak demand periods. This is especially useful for maximising energy independence and reducing reliance on the grid.
  


• 
  Mounting System: This framework securely attaches the solar panels to your roof, ensuring they are positioned at the optimal angle to capture sunlight.
  


• 
  Monitoring System: A monitoring system allows you to track your energy production and consumption in real-time, helping you optimise usage and identify any potential issues.

Process of Solar System Installation

Step 1: Find Out if Solar is Right for Your Home

First, you must decide whether installing solar panels in your house is possible. Schedule a meeting with a solar panel installer to evaluate your home and determine eligibility. The installer will examine your roof space, solar exposure, and shady area. North-facing roofs are the best in Australia, but east or west facing roofs can be also used.

Step 2: Choose the Right Solar Installer

Selecting a good installer is vital. Select a solar installer involved in a consumer protection program like the New Energy Tech Consumer Code (NETCC) Program. Established by the Clean Energy Council, this program provides national benchmarks to safeguard consumers. Other sources one can use are friends or family. Online reviews and ratings can assist in choosing a good solar panel installer.

Step 3: Compare Quotes

Research to acquire quotations from different installers. A good quote should involve a site-specific system design, an installation schedule and a performance expectation. It should also list all parts and products, the guarantee, and a component cost list. This also includes any rebates, discounts or any amount of money that is given back to you.

Step 4: Sign the Contract

After deciding on the installer, you must enter a contract. Ensure the contract is understandable and does not contain jargon or complex legal language. Discuss the payment procedure and select the most suitable payment method for you. This means that before putting your signature on any legal document, ensure you have carefully reviewed the document's content, especially the parts that include the contract terms.

Step 5: Schedule the Installation

Your installer will arrange a particular day to carry out the installation. It often lasts one or two days, depending on the number of modules and the system's overall size. The installer will then connect the wires, turn on the system, and reactivate it after testing. They should also include information on using the system through information sheets or manuals for every part.

How to Select the Appropriate Solar System for Your House

Assess Your Energy Consumption

Before selecting a particular solar system, evaluate your energy demands. Look at your energy payments to determine how many lighting devices you use daily. These suggestions will assist you in selecting the appropriate size for your solar device.

Consider Your Roof Space and Orientation

The size of the roof and its orientation are factors that cannot be overlooked. The North-facing roofs provide the most heat in Australia, but roofs facing east or west can also collect heat. Ensure you have enough roof space to accommodate the required number of panels.

Set Your Budget

Like automobiles, solar systems vary in size and cost. Choose a unit that meets your energy requirements without charging too much. Always remember that a solar system is an investment that will pay back in the long run.

Costs of Solar Panel Installation

Initial Costs

The average cost of solar panel installation in Australia depends on the system size. A small 3-4 kW system costs around $3,000 to $5,000, a medium 5-6 kW system ranges from $4,500 to $8,000, and a large 7-10 kW system can cost between $7,000 and $12,000. These prices include panels, inverters, and installation. Government incentives, like STCs, can reduce costs by up to 30%.

Ongoing Costs

Solar systems are low-maintenance, with occasional cleaning and inspections costing around $150-$300 annually. Inverters may need replacing after 10-15 years, costing $1,000−$2,000.
