Drouin West, Victoria, Australia, situated in the Southern Temperate Zone, presents a varied landscape for solar energy generation throughout the year. This location experiences significant fluctuations in solar output across different seasons, which is typical for areas in temperate climates.
Seasonal Solar Performance
The solar energy potential at Drouin West varies considerably across the seasons. Summer stands out as the most productive period, with an impressive daily output of 7.34kWh per kW of installed solar capacity. Spring follows as the second-best season, generating 5.84kWh/day. Autumn sees a noticeable decrease in production at 3.76kWh/day, while winter experiences the lowest output at 2.49kWh/day.
Optimal Times for Solar Generation
The ideal times for solar energy production in Drouin West are during the summer months, typically from December to February, when daylight hours are longest and solar intensity is at its peak. Spring (September to November) also offers favorable conditions for solar generation. These seasons provide the best opportunity to maximize solar energy harvesting and potentially produce excess energy for storage or grid feed-in.
Panel Tilt Angle for Maximum Efficiency
For fixed solar panel installations in Drouin West, the optimal tilt angle to maximize year-round energy production is 33 degrees facing North. This angle is calculated based on the location's latitude and accounts for the Earth's elliptical orbit, ensuring the best overall performance across all seasons.
Environmental and Weather Considerations
While Drouin West generally offers good conditions for solar energy production, there are some factors that could potentially impact solar panel efficiency:
- Cloud cover: The region can experience overcast days, particularly during winter, which may reduce solar output.
- Dust and pollen: Being in a rural area, airborne particles could accumulate on panels, slightly decreasing their efficiency.
To mitigate these factors, regular panel cleaning and maintenance should be scheduled. Additionally, investing in high-quality, weather-resistant panels and considering a slight oversizing of the system can help ensure consistent energy production throughout the year.
In conclusion, while Drouin West experiences seasonal variations in solar output, it remains a viable location for solar PV installations. With proper planning and maintenance, residents can effectively harness solar energy, particularly during the productive summer and spring months.

Solar output per kW of installed solar PV by season in Drouin West
Seasonal solar PV output for Latitude: -38.0824, Longitude: 145.8628 (Drouin West, 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 33° North in Drouin West, Australia
To maximize your solar PV system's energy output in Drouin West, Australia (Lat/Long -38.0824, 145.8628) 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 Drouin West, 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 Drouin West, 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 |
|---|---|---|---|
| 22° North in Summer | 43° North in Autumn | 53° 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.
Calculate solar panel row spacing in Drouin West, Australia

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 Drouin West, Australia
The topography around Drouin West, Australia, located at latitude -38.0824 and longitude 145.8628, is characterized by gently rolling hills and valleys typical of the West Gippsland region in Victoria. This area is situated on the eastern edge of the Gippsland Plains, transitioning into the foothills of the Strzelecki Ranges to the south. The landscape surrounding Drouin West features a mix of open farmland, patches of native bushland, and scattered residential areas. The terrain is generally undulating, with elevations ranging from about 100 to 200 meters above sea level. Small creeks and streams crisscross the area, contributing to the region's lush, green appearance. To the north and east of Drouin West, the land becomes slightly flatter, with broader valleys and more expansive agricultural fields. This gradual transition from hilly to flatter terrain continues as one moves further north towards the La Trobe Valley.
Potential for Large-Scale Solar PV
When considering areas nearby that would be most suited to large-scale solar PV installations, several factors come into play. The ideal locations would have relatively flat or gently sloping terrain, good sun exposure, and minimal shading from surrounding hills or vegetation. The areas to the north and northeast of Drouin West show the most promise for large-scale solar PV projects. These regions tend to have more open, less undulating landscapes with fewer trees, which would minimize shading issues. The flatter terrain would also reduce the costs associated with land preparation and installation of solar panels. Specific locations that might be suitable include the agricultural areas between Drouin West and Warragul, or the more open farmlands north of Warragul towards Darnum and Nilma. These areas generally have good road access, which is beneficial for construction and maintenance of solar facilities. It's important to note that while the topography in these areas may be suitable, other factors such as grid connection availability, local planning regulations, and environmental considerations would also need to be taken into account when assessing the feasibility of large-scale solar PV installations in the region.Australia solar PV Stats as a country
