Understanding solar panel orientation and tilt
The optimal orientation and tilt for solar panels in Australia can vary depending on your specific location. However, general guidelines suggest facing the panels north or northwest to capture the maximum sunlight throughout the year. The tilt angle should be adjusted seasonally to optimise sunlight absorption.
Factors affecting sunlight exposure
Several factors can influence the amount of sunlight your solar panels receive, including:
- Roof orientation: Your roof’s orientation plays a significant role in determining the optimal placement for your solar panels. A north-facing roof is generally ideal, but other orientations can still be viable with careful planning. Learn more about: Which direction should solar panels face in Australia?
- Local climate: Australia’s diverse climate can impact solar panel performance. When selecting a location, consider your region’s cloud cover, rainfall, and temperature variations.
- Shading: Trees, buildings, or other obstructions can cast shadows on your solar panels, reducing efficiency. Choosing a location with minimal shading throughout the day is essential, especially during peak sunlight hours.

Seasonal variations: The sun’s angle changes throughout the year, affecting the sunlight that reaches your solar panels. Proper tilt adjustments maximise energy production during different seasons. Check our page to learn about Seasonal Solar Energy Tips for Australian Homeowners.
Solar panel placement tips for maximum sunlight exposure
- Conduct a solar survey: Before installing solar panels, have a solar survey conducted to assess your roof’s suitability, identify potential shading issues, and determine the optimal orientation and tilt angles for your location.
- Prioritise clear views: Choose a location on your roof with unobstructed views of the sky, especially in the direction of the sun’s path throughout the day.
- Avoid shading: Consider the surrounding environment to minimise shading from trees, buildings, or other structures. If necessary, trim trees or remove obstructions to ensure maximum sunlight exposure.
- Consider roof orientation: If your roof is not ideally oriented towards the north, explore options such as ground-mounted solar systems or solar trackers to optimise sun exposure.
- Factor in local climate: Research the average sunlight hours, cloud cover, and rainfall patterns in your area to make informed decisions about solar panel placement.
- Invest in high-quality panels: Choose solar panels from reputable manufacturers with proven track records and warranties. Quality panels are more likely to maintain efficiency over time and withstand harsh weather conditions.
- Utilise solar calculators: Online solar calculators can help you estimate the potential energy production of your solar system based on various factors, including location, panel size, and orientation.
