What is the best tilt angle for solar panels in Melbourne?

If you are considering solar panel installation angle in Melbourne, you may be wondering what the best inclination angle is at which the solar panels are mounted on your roof. The ideal tilt angle will vary depending on your location, the orientation of your roof, and the type of solar panels you have installed.

The best tilt angle for solar panels in Melbourne

When it comes to optimizing the tilt angle of solar panel angle Melbourne, there are some general guidelines to consider to maximize energy production throughout the year. Melbourne’s latitude, climate, and seasonal variations in the sun’s position all play a role in determining the ideal tilt angles.

  • Fixed Tilt Angle: For homeowners who don’t want the hassle of adjusting their solar panels seasonally, a fixed tilt angle is a practical choice. In Melbourne, a fixed tilt angle of around 37 degrees is often recommended. This angle closely matches Melbourne’s latitude and provides good year-round energy production.
  • Seasonal Adjustment: To further optimize energy production, you can consider adjusting the tilt angle of your solar panels seasonally. Here’s a rough guideline for seasonal adjustments:
  • Winter Tilt Angle: During winter, when the sun is lower in the sky, it’s beneficial to tilt your panels at a steeper angle. This angle can be increased to around 50-55 degrees. This steep tilt angle helps capture more sunlight during the shorter and lower-angle winter days.
  • Summer Tilt Angle: In summer, when the sun is higher in the sky, you can flatten the tilt angle of your panels to around 20-25 degrees. This allows the panels to capture the higher-angle sunlight effectively.
  • Spring and Fall Adjustments: During the transitional seasons of spring (September to November) and fall (March to May), you can adjust your panels to a position between the winter and summer angles. For spring, gradually reduce the winter tilt angle as the days get longer and the sun’s position rises. In the fall, increase the tilt angle as the days shorten and the sun’s position lowers.
  • Automation or Manual Adjustment: To make these seasonal adjustments easier, some solar panel systems offer automation, allowing the panels to change their tilt angle automatically based on the sun’s position. however, these systems can be more expensive. If you have a fixed tilt solar panel system, you may need to manually adjust the tilt angle several times a year.
  • Monitor Performance: Keep an eye on your solar panel system’s performance throughout the year. If you notice that energy production is not meeting expectations, it may be time to make tilt angle adjustments.
  • Solar Tracking Systems: For those looking to maximize energy production and are willing to invest in advanced technology, solar tracking systems can automatically adjust the tilt and orientation of solar panels throughout the day to follow the sun’s path.

    The optimal tilt angle for solar panels is influenced by a variety of factors,

    each of which plays a crucial role in maximizing energy production and efficiency. When determining the ideal tilt angle for your solar panels in Melbourne, VIC, consider the following key factors:

    • Latitude: Melbourne’s latitude, which is approximately 37 degrees south, is a fundamental factor in determining the optimal tilt angle. In general, the tilt angle for solar panels should be set approximately equal to the latitude of the location. For Melbourne, this means a tilt angle of around 37 degrees.
    • Seasonal Sun Paths: The sun’s position in the sky changes with the seasons. During winter, the sun is lower in the sky, while in summer, it’s higher. To maximize energy production, consider adjusting the tilt angle of your solar panels seasonally. 
    • Roof orientation: The orientation of your roof or the mounting structure for your solar panels also plays a significant role. Solar panels should ideally face true south in the Southern Hemisphere to receive maximum sunlight throughout the day.
    • Shading: The presence of shading from trees, nearby buildings, or other obstructions can impact the optimal tilt angle. Tilt your panels to minimize shading throughout the day. Keep in mind that even small amounts of shading can significantly reduce energy production, so it’s crucial to choose an angle that minimizes shadows.
    • Panel Type: Different types of solar panels may have slightly different optimal tilt angles. Monocrystalline, polycrystalline, and thin-film panels may perform best at slightly different angles. Consult with your solar panel manufacturer or installer to determine the ideal tilt angle for your specific panel type.
    • Local Climate: Melbourne experiences different weather conditions throughout the year. Consider the local climate, including rainfall, wind, and extreme weather events, when determining the tilt angle. Ensuring that your panels are securely mounted and tilted appropriately can help them withstand these conditions.
    • Aesthetics and Roof Space: Sometimes, practical considerations such as available roof space and the visual impact of solar panels on your home may influence the tilt angle. You may need to compromise between aesthetics and optimal tilt angle to maximize energy production while maintaining the look of your property.

    How to tilt your solar panels

    If you’re not sure what the best solar panel angle Melbourne, you can always consult with a solar installer. They can help you assess your specific situation and recommend the best tilt angle for your needs. To tilt your solar panels, you’ll need to use a solar panel mounting system. There are a variety of mounting systems available, so you’ll need to choose one that is compatible with your roof and the type of solar panels you install.


    The best tilt angle for solar panels in Melbourne is 32 degrees, the latitude of Melbourne. Therefore, the ideal tilt angle will vary depending on a number of factors, such as the roof pitch, the orientation of the roof, and the time of year.
