Balancing your budgetary constraints with your long-term energy goals will help guide the design and configuration of your solar energy system.

Assessment of Roof

Sun Ready? Assessing Your Roof for Solar Panel Installation

So you’re excited about making the switch to solar power – fantastic! Before you get too caught up in imagining the sunshine powering your home, assessing your roof’s suitability for solar panel installation is essential. After all, your roof will be the foundation for your clean energy future.

This guide will help you with the knowledge to evaluate your roof and ensure it’s ready to become a solar powerhouse.

Key Factors for Roof Assessment:

  • Sunlight Exposure and Roof Direction: In Australia, the orientation of your home is usually based on whether the living areas face north. This is because north-facing rooms receive sunlight for the most extended period of the day in winter. For solar panels to work effectively, they need to be installed on a north-facing roof.
  • Roof Size and Shape: Your roof’s size directly affects the number of solar panels you can install, impacting the overall energy generation capacity. A larger, unobstructed roof is ideal, but even smaller or oddly shaped roofs can accommodate solar panels with creative planning.
  • Roof Pitch: The angle of your roof slope also plays a role. Generally, a roof pitch between 20 and 40 degrees is optimal for solar panel installation, as it allows for maximum sunlight exposure and minimises the risk of debris accumulation. However, flatter roofs can still work with proper mounting systems.
  • Roof Material: Many roofing materials, like tin or tile roofs, including asphalt shingles, metal roofs, and concrete tiles, can work well with solar panels. Nonetheless, it’s crucial to confirm that your roof is in good shape and has a long enough lifespan to handle the weight and potential impact of the panels.
  •  Shading: Trees, power lines, or nearby structures casting shade on your roof can significantly impact solar panel efficiency. Analyse potential shading patterns throughout the day to ensure your panels receive optimal sunlight.

Permits and Documentation

Navigating the legal landscape is crucial for a compliant installation:

Local Council Regulations: You’ll need to adhere to specific regulations set by your local council, which may include restrictions on panel placement and aesthetics.

Building Permits: Depending on where you are situated, you might be required by law to acquire specific building permits to install solar panels on your property.

Grid Connection Approval: You must apply for grid connection approval from your energy distributor before installation.

Choosing Equipment

Product Selection Process:

Choose high-quality solar panels and inverters suitable for the Australian climate and conditions. These products are known for their reliability, performance, and durability.


  • Panel Types: Select solar panels with high-efficiency ratings and durability to withstand Australia’s harsh weather conditions, such as heat, UV exposure, and potential hailstorms.
  • Inverter Options: Choose inverters optimised for Australian grid conditions and voltage requirements. This will ensure compatibility and efficiency in converting solar energy into usable AC electricity for your home.


Consider reputable brands with a strong presence in the Australian market, offering warranties and support tailored to Australian homeowners, such as LG, Trina Solar, SunPower, and Sungrow.

Professional Installation:

  • Certified installers with experience in the Australian solar industry will handle the installation process, ensuring compliance with Australian standards and regulations.
  • Installation Steps:
  • Roof Mounting: Securely mount the solar panels on your roof using robust racking systems designed to withstand Australia’s weather extremes, including high winds and potential cyclones.
  • Electrical Wiring: When connecting solar panels to your home’s electrical system, it’s essential to adhere to Australian electrical safety standards and regulations to ensure safe and reliable operation.
  • Inverter Installation: Please install inverters in a good location where they will be safe from very hot or cold temperatures and bad weather. This will make sure they work well and use energy effectively.

How do solar panel systems work?

Solar panels use sunlight to make electricity. The panels have PV cells that convert sunlight into direct (DC) electricity. An inverter converts the DC electricity into alternating current (AC) electricity, which can connect household appliances to the grid.

The electricity generation output of a solar panel system is influenced by various factors, including its location, panel orientation, and the presence of any shading. Solar panels perform a little inefficiently when facing south, with minimal obstruction from trees or buildings.

The following are the components required for Solar Panel Installation:

  1. Solar panels: Solar panels or PV Panels are the most visible part of a solar panel system and come in various sizes and types. The most common type is the monocrystalline or polycrystalline silicon panels.
  2. Inverter: This essential component converts direct current (DC) electricity into alternating current (AC) electricity, which can power appliances and be sent back to the grid.
  3. Mounting system: Solar panels mounted on a secure structure, like a roof or a ground-mounted frame, can be positioned at the best angle to receive maximum sunlight exposure.
  4. Batteries: You can add optional batteries to your solar panel system to store any excess energy generated during sunny periods. This stored energy can be used during times of low sunlight or power outages.
  5. Monitoring system: Solar panel systems often come equipped with a monitoring system that enables users to monitor their energy production and usage in real-time

Panel Orientation. The key to peak performance

Orientation is crucial for achieving peak performance from solar panels. In Australia, panels can be positioned to face north, northeast, northwest, or west. Our retail solar partners specialise in determining the optimal direction and angle for panel placement on your home. They consider the sun’s path throughout the year, ensuring that your solar system operates efficiently regardless of the season. With this approach, your solar panels will work tirelessly year-round, maximising energy production daily.
