Corlette, New South Wales, Australia, situated in the Southern Sub Tropics, offers a promising location for solar PV energy generation. The year-round electricity output from solar panels in this area varies significantly across seasons, reflecting the region's subtropical climate patterns.

Seasonal Solar Performance

Summer stands out as the most productive season, with an impressive 6.79kWh per day for each kilowatt of installed solar capacity. Spring follows closely, generating 6.05kWh/day. These seasons provide ideal conditions for solar energy production, with longer days and more direct sunlight.

Autumn sees a noticeable decrease in output, producing 4.24kWh/day. Winter experiences the lowest generation at 3.35kWh/day, primarily due to shorter days and the sun's lower position in the sky.

Optimal Panel Positioning

For fixed panel installations in Corlette, the ideal tilt angle to maximize year-round solar production is 29 degrees facing North. This angle optimizes the panels' exposure to sunlight throughout the year, balancing the varying sun positions across seasons.

Environmental Considerations

While Corlette's climate is generally favorable for solar energy, there are some environmental factors to consider:

• Coastal location: Proximity to the ocean may lead to salt spray, potentially affecting panel efficiency over time.
• Vegetation: Trees or tall structures could cast shadows on panels, reducing their effectiveness.

Preventative Measures

To mitigate these factors and ensure optimal solar production:

• Use corrosion-resistant materials and regularly clean panels to combat salt spray effects.
• Conduct a thorough site assessment to identify and address potential shading issues.
• Consider micro-inverters or power optimizers to minimize the impact of partial shading.

Overall, Corlette's location offers excellent potential for solar PV energy generation, particularly during summer and spring. With proper installation and maintenance, solar panels can provide significant energy output throughout the year.

Note: The Southern Sub Tropics extend from -23.5° latitude South down to -35° latitude.

So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 501 locations across Australia. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Solar output per kW of installed solar PV by season in Corlette

Seasonal solar PV output for Latitude: -32.7275, Longitude: 152.114 (Corlette, 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 29° North in Corlette, Australia

To maximize your solar PV system's energy output in Corlette, Australia (Lat/Long -32.7275, 152.114) throughout the year, you should tilt your panels at an angle of 29° 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 Corlette, 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 Corlette, Australia. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 29° North tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
16° North in Summer	38° North in Autumn	48° North in Winter	27° 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 Corlette, 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 Corlette, Australia.

Our calculation method

1. Solar Position:
   We determine the Sun's position on the Winter solstice using the location's latitude and solar declination.
2. Shadow Projection:
   We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle.
3. 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 Corlette, Australia

The topography around Corlette, Australia, located at latitude -32.7275 and longitude 152.114, is characterized by a diverse coastal landscape. Situated on the eastern coast of New South Wales, Corlette is part of the Port Stephens area, known for its stunning natural beauty and varied terrain. The immediate surroundings of Corlette feature a mix of gently rolling hills and low-lying coastal plains. To the north and west, the land gradually rises, forming a series of undulating hills that provide picturesque views of the nearby bays and inlets. These hills are often covered with native vegetation, including eucalyptus forests and coastal scrubland. To the east, Corlette is bordered by the calm waters of Port Stephens, a large natural harbor that stretches for about 134 square kilometers. The shoreline is dotted with sandy beaches, rocky outcrops, and small coves, creating a rugged and scenic coastline. The southern shore of Port Stephens features a series of headlands and bays, adding to the area's geographical diversity. Inland from Corlette, the landscape becomes more varied. The terrain transitions into a mix of flat to gently sloping areas, interspersed with pockets of steeper hillsides. This inland region is characterized by a combination of cleared farmland, patches of native bushland, and scattered residential developments.

Suitability 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 location would have relatively flat or gently sloping terrain, good sun exposure, and minimal shading from surrounding landscape features. The areas to the west and northwest of Corlette present promising opportunities for solar PV development. These inland regions, particularly around the localities of Raymond Terrace and Medowie, offer larger tracts of cleared land with favorable topography. The gently undulating terrain in these areas provides good solar exposure while minimizing the need for extensive earthworks. Another potentially suitable area lies to the southwest, in the vicinity of Hexham and Tomago. This region features expansive flat lands, some of which are already used for industrial purposes. The open nature of this landscape, combined with its proximity to existing infrastructure, makes it an attractive option for large-scale solar installations. It's important to note that while these areas may be topographically suitable, other factors such as land ownership, environmental considerations, and proximity to the electrical grid would also need to be taken into account when planning any large-scale solar PV project. Additionally, detailed site-specific assessments would be necessary to determine the exact suitability of any particular location.

Australia solar PV Stats as a country

Australia ranks 7th in the world for cumulative solar PV capacity, with 19,076 total MW's of solar PV installed.
