Goongerah, Victoria, Australia, located at latitude -37.3404 and longitude 148.6918, presents varying potential for solar energy generation throughout the year. This location in the Southern Temperate Zone experiences significant seasonal fluctuations in solar output, which impacts the overall efficiency of solar PV systems.
Seasonal Solar Performance
Summer stands out as the most productive season for solar energy in Goongerah, with an impressive daily output of 6.77 kWh per kW of installed solar capacity. Spring follows as the second-best season, generating 5.26 kWh/day. Autumn sees a noticeable decrease in production at 3.90 kWh/day, while winter experiences the lowest output at 2.58 kWh/day.
These figures indicate that solar energy generation in Goongerah is most effective during the warmer months, particularly from late spring through early autumn. This period offers longer daylight hours and more direct sunlight, maximizing the potential of solar PV systems.
Optimal Panel Installation
To achieve the best year-round solar production in Goongerah, fixed solar panels should be tilted at an angle of 33 degrees facing North. This orientation helps capture the maximum amount of sunlight throughout the year, balancing the seasonal variations in the sun's position.
Environmental Considerations
While Goongerah's location is generally favorable for solar energy production, there are some environmental factors to consider. The area is known for its dense forests, which could potentially cast shadows on solar panels, especially during winter when the sun's angle is lower. To mitigate this, careful site selection is crucial, preferably choosing open areas with minimal tree coverage to the north.
Additionally, the region can experience bushfires during hot, dry summers. While not directly impacting solar production, the smoke and ash from these events could temporarily reduce panel efficiency. Regular cleaning and maintenance of solar panels can help minimize this impact.
Weather-Related Challenges
Goongerah's climate includes occasional heavy rainfall and storms, particularly during winter and spring. While these events are typically short-lived, they can temporarily reduce solar output. Installing high-quality, weather-resistant panels and ensuring proper drainage around the installation site can help maintain optimal performance during wet weather.
In conclusion, while Goongerah faces some challenges for solar energy production, particularly during winter months, its overall potential remains promising. With proper planning, optimal panel orientation, and regular maintenance, solar PV systems can effectively harness the abundant sunlight available, especially during the warmer seasons.

Ideally tilt fixed solar panels 33° North in Goongerah, Australia
To maximize your solar PV system's energy output in Goongerah, Australia (Lat/Long -37.3404, 148.6918) throughout the year, you should tilt your panels at an angle of 33° 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 Goongerah, 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 Goongerah, Australia. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 33° 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 | 31° 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.

Our calculation method
- Solar Position:
We determine the Sun's position on the Winter solstice using the location's latitude and solar declination. - Shadow Projection:
We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle. - Minimum Spacing:
We add the shadow length to the horizontal space occupied by tilted panels.
This approach ensures maximum space efficiency while avoiding shading during critical times, as the Winter solstice represents the worst-case scenario for shadow length.
Topography for solar PV around Goongerah, Australia
The topography around Goongerah, Australia, is characterized by a diverse and rugged landscape typical of the East Gippsland region in Victoria. Situated in a remote area of the state, Goongerah is surrounded by dense forests, rolling hills, and steep valleys. The terrain is predominantly hilly, with elevations ranging from around 200 to 600 meters above sea level. The area is part of the Great Dividing Range, which runs along Australia's eastern coast. As a result, the landscape features a mix of ridges, gullies, and plateaus. The Brodribb River and its tributaries wind through the region, carving out valleys and creating natural boundaries between the hills and mountains. The vegetation in the area is primarily composed of eucalyptus forests, with pockets of rainforest in the more sheltered gullies and along watercourses. This dense forest cover contributes to the area's reputation as a biodiversity hotspot and provides habitat for numerous native species.
Suitability for Large-Scale Solar PV
When considering areas nearby that would be most suited to large-scale solar PV installations, several factors need to be taken into account. The ideal location for solar farms typically requires relatively flat terrain, good sun exposure, and proximity to existing infrastructure. In the vicinity of Goongerah, the most suitable areas for large-scale solar PV would likely be found on the less forested, gently sloping hillsides or plateaus. These areas would offer better sun exposure compared to the densely forested valleys. However, it's important to note that the overall rugged nature of the landscape and the extensive forest cover may present challenges for large-scale solar development in the immediate vicinity. Areas to the north and west of Goongerah, where the terrain becomes slightly less mountainous and more open, might offer more promising locations for solar PV installations. These regions, while still hilly, tend to have larger cleared areas that could potentially accommodate solar farms. It's worth noting that any large-scale solar development in this region would need to carefully consider environmental impacts, given the area's ecological significance. Additionally, the remoteness of the location may present challenges in terms of grid connection and infrastructure development, which are crucial factors in the feasibility of large-scale solar projects.Australia solar PV Stats as a country
