Liverpool, New South Wales, Australia, situated in the Southern Sub Tropics, presents a favorable location for solar PV energy generation throughout the year. The city's geographical position at latitude -33.9254 and longitude 150.9284 offers substantial potential for harnessing solar power, with varying levels of efficiency across different seasons.
Seasonal Solar Performance
Solar energy production in Liverpool exhibits notable fluctuations across the four meteorological seasons. Summer stands out as the most productive period, with an impressive daily output of 6.47kWh per kW of installed solar capacity. Spring follows closely, generating 5.73kWh/day, while autumn yields a respectable 4.36kWh/day. Winter, as expected, shows the lowest output at 3.21kWh/day, but still contributes significantly to the overall annual energy production.
Optimal Times for Solar Generation
The most ideal times for solar energy generation in Liverpool 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) and autumn (March to May) also offer excellent opportunities for solar power production, with moderate temperatures and clear skies contributing to efficient energy conversion.
Panel Installation Considerations
For maximum year-round solar energy production, fixed solar panels in Liverpool should be installed at a tilt angle of 31 degrees facing north. This optimal angle ensures that the panels capture the most sunlight throughout the year, accounting for the Earth's elliptical orbit and the city's specific latitude.
Environmental and Weather Factors
While Liverpool generally provides favorable conditions for solar energy production, there are a few factors that could potentially impact efficiency:
- Occasional dust storms: These can temporarily reduce panel efficiency by coating the surfaces with fine particles.
- Summer heatwaves: Extremely high temperatures can slightly decrease solar panel efficiency.
To mitigate these issues, regular cleaning of solar panels is recommended, especially after dust storms. Additionally, ensuring proper ventilation behind the panels during installation can help manage heat-related efficiency losses during intense summer periods.
Overall, Liverpool's climate and geographical location make it an excellent choice for solar PV installations, with the potential for substantial energy generation throughout the year.

Seasonal solar PV output for Latitude: -33.9254, Longitude: 150.9284 (Liverpool, 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 31° North in Liverpool, Australia
To maximize your solar PV system's energy output in Liverpool, Australia (Lat/Long -33.9254, 150.9284) throughout the year, you should tilt your panels at an angle of 31° 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 Liverpool, 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 Liverpool, Australia. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 31° North tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 18° North in Summer | 39° North in Autumn | 49° North in Winter | 28° 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 Liverpool, Australia
We've added a feature to calculate minimum solar panel row spacing by location. Enter your panel size and orientation below to get the minimum spacing in Liverpool, 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 Liverpool, Australia
The topography around Liverpool, Australia, located at latitude -33.9254 and longitude 150.9284, is characterized by a mix of gently rolling hills and flat plains. This area, situated in the western suburbs of Sydney, is part of the Cumberland Plain, a large expanse of relatively low-lying land that stretches across much of western Sydney. Liverpool itself sits at an elevation of approximately 25 meters above sea level. As you move away from the city center, the landscape gradually rises, with some areas reaching elevations of up to 100 meters. The terrain is generally mild, with no dramatic changes in elevation or steep cliffs. The Georges River flows through the region, creating some variations in the landscape and forming small valleys and flood plains along its course. To the west and southwest of Liverpool, the land becomes slightly more undulating, with a series of low hills and ridges. These areas, including suburbs like Bringelly and Luddenham, have a more rural character and feature open grasslands interspersed with patches of woodland.
Suitability for Large-Scale Solar PV
When considering areas nearby Liverpool that would be most suited to large-scale solar photovoltaic (PV) installations, several factors come into play. The ideal location would have ample flat or gently sloping land, good sun exposure, and minimal shading from trees or buildings. The areas to the west and southwest of Liverpool, particularly in the direction of Bringelly and Badgerys Creek, offer promising potential for solar PV development. These regions have several advantages: 1. They feature expansive, open areas with relatively flat terrain, which is ideal for the installation of large solar arrays. 2. The land in these areas is less densely populated and developed compared to the suburbs closer to Sydney, providing more space for large-scale projects. 3. The slightly elevated nature of some of these areas could potentially offer good sun exposure throughout the day. 4. The rural character of these regions means there are fewer tall buildings or dense urban development that could cast shadows on solar panels. It's worth noting that while these areas show promise for solar PV development, any large-scale project would require detailed site-specific assessments. Factors such as local zoning regulations, environmental considerations, and proximity to electrical infrastructure would all need to be carefully evaluated before proceeding with any solar installation plans.Australia solar PV Stats as a country
