Riddells Creek, Victoria, Australia, offers a varied solar energy potential throughout the year. Located in the Southern Temperate Zone, this area experiences distinct seasonal changes that affect solar PV electricity generation.
Seasonal Solar Performance
Summer stands out as the most productive season, with an impressive 7.56kWh/day per kW of installed solar capacity. Spring follows as the second-best season, generating 5.76kWh/day. Autumn sees a significant drop to 3.92kWh/day, while winter performance dips to its lowest at 2.48kWh/day.
The substantial difference between summer and winter output highlights the importance of proper system sizing to ensure adequate year-round energy production. While summer months provide ample solar energy, winter months may require supplementary power sources or energy storage solutions.
Optimal Panel Placement
For fixed panel installations in Riddells Creek, the ideal tilt angle to maximize year-round solar production is 32 degrees facing North. This angle optimizes the panels' exposure to sunlight throughout the year, considering the location's latitude and seasonal sun paths.
Environmental Considerations
While Riddells Creek generally offers favorable conditions for solar energy production, there are a few environmental factors to consider:
- Dust and pollen: The rural setting may lead to dust accumulation on panels, potentially reducing efficiency.
- Tree shading: Nearby vegetation could cast shadows on panels, especially during winter when the sun is lower in the sky.
To mitigate these issues, regular panel cleaning and strategic placement away from potential shading sources are recommended. Additionally, installing micro-inverters or power optimizers can help minimize the impact of partial shading on overall system performance.
Conclusion
Despite seasonal variations, Riddells Creek presents a good location for solar PV installations. With proper system design and maintenance, residents can harness significant solar energy, particularly during the spring and summer months, while implementing strategies to optimize winter performance.

Solar output per kW of installed solar PV by season in Riddells Creek
Seasonal solar PV output for Latitude: -37.4619, Longitude: 144.6844 (Riddells Creek, Australia), based on our analysis of 8760 hourly intervals of solar and meteorological data (one whole year) retrieved for that set of coordinates/location from NASA POWER (The Prediction of Worldwide Energy Resources) API:
 
Ideally tilt fixed solar panels 32° North in Riddells Creek, Australia
To maximize your solar PV system's energy output in Riddells Creek, Australia (Lat/Long -37.4619, 144.6844) throughout the year, you should tilt your panels at an angle of 32° North for fixed panel installations.
As the Earth revolves around the Sun each year, the maximum angle of elevation of the Sun varies by +/- 23.45 degrees from its equinox elevation angle for a particular latitude. Finding the exact optimal angle to maximise solar PV production throughout the year can be challenging, but with careful consideration of historical solar energy and meteorological data for a certain location, it can be done precisely.
We use our own calculation, which incorporates NASA solar and meteorological data for the exact Lat/Long coordinates, to determine the ideal tilt angle of a solar panel that will yield maximum annual solar output. We calculate the optimal angle for each day of the year, taking into account its contribution to the yearly total PV potential at that specific location.
Seasonally adjusted solar panel tilt angles for Riddells Creek, Australia
If you can adjust the tilt angle of your solar PV panels, please refer to the seasonal tilt angles below for optimal solar energy production in Riddells Creek, Australia. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 32° North tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 21° North in Summer | 42° North in Autumn | 52° North in Winter | 30° North in Spring |
Our recommendations take into account more than just latitude and Earth's position in its elliptical orbit around the Sun. We also incorporate historical solar and meteorological data from NASA's Prediction of Worldwide Energy Resources (POWER) API to assign a weight to each ideal angle for each day based on its historical contribution to overall solar PV potential during a specific season.
This approach allows us to provide much more accurate recommendations than relying solely on latitude, as it considers unique weather conditions in different locations sharing the same latitude worldwide.
