Solar PV Analysis of Nelson Bay, Australia
Nelson Bay, New South Wales, Australia is a pretty good spot for generating solar energy all year round. In simpler terms, the amount of sunlight this area gets can be converted into electricity using solar panels. During summer and spring, the area gets more sunlight (6.78kWh/day and 6.07kWh/day respectively) than in autumn or winter (4.30kWh/day and 3.41kWh/day respectively). So, you'd get more electricity from your solar panels in summer and spring.
For the best results throughout the year, if you were to install solar panels here, you should tilt them at an angle of 29 degrees facing north. This position would catch the most sunlight over all four seasons.
However, there are some things that might make it harder for your panels to generate power here at Nelson Bay:
- Weather: The amount of cloud cover can affect how much sun reaches your panels.
- Topography: The landscape around where you want to put your panel can also affect how much sun it gets - like if there's a mountain blocking early morning light.
- Local factors: Buildings or trees that cast shadows over where you want to put your panel could also be an issue.
To ensure that these factors don't interfere too much with your solar production:
- Try positioning your panel somewhere high up where other buildings or trees are less likely to block its light.
- Make sure nothing is covering or shading the panel throughout different times of day.
- Regularly clean and maintain them so they're always working as efficiently as possible.
Overall though, Nelson Bay seems like a pretty ideal spot for generating solar energy!
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 Nelson Bay
Seasonal solar PV output for Latitude: -32.7206751, Longitude: 152.1414806 (Nelson Bay, 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 Nelson Bay, Australia
To maximize your solar PV system's energy output in Nelson Bay, Australia (Lat/Long -32.7206751, 152.1414806) 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 Nelson Bay, 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 Nelson Bay, 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 | 26° 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 Nelson Bay, 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 Nelson Bay, 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 Nelson Bay, Australia
Nelson Bay, Australia is located in the Port Stephens region of New South Wales. The topography of this area is characterized by a mix of coastal plains and undulating hills, with some areas featuring more rugged terrain. The coastline features several beautiful beaches and the bay itself.
The region also has several nature reserves and national parks, including the Tomaree National Park which features forested areas as well as rocky outcrops. There are also wetland areas in close proximity to Nelson Bay.
When considering large-scale solar PV installations, flat or gently sloping land is generally most suitable due to ease of installation and maintenance, as well as optimal sun exposure for the panels. Areas away from dense vegetation or shadow-casting structures would also be preferable to minimize shading on the panels.
In terms of specific locations around Nelson Bay that may be suitable for large-scale solar PV installations, it's important to consider factors such as land use zoning regulations and environmental impacts. However, theoretically speaking based on topography alone:
1) The relatively flat coastal plains around Nelson Bay could potentially be suited for such a project.
2) Areas with agricultural land use further inland might also be potential sites if they feature sufficient sun exposure.
3) Some parts of Salt Ash or Bobs Farm might be suitable due to their relatively flat terrain and open spaces.
However, any proposal for a large-scale solar PV installation would need to undergo thorough site assessment including environmental impact studies and consultations with local communities before proceeding.
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. This means that 10.70% of Australia's total energy as a country comes from solar PV (that's 2nd in the world). Each year Australia is generating 742 Watts from solar PV per capita (Australia ranks 2nd in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Australia?
Yes, there are a variety of incentives available in Australia to businesses wanting to install solar energy. These include:
1. Renewable Energy Target (RET): The RET provides businesses with financial assistance for installing and operating renewable energy systems such as solar panels. Businesses may be eligible to receive certificates that can be sold or traded on the open market for additional income.
2. Feed-in Tariffs: Some states offer feed-in tariffs which pay businesses for generating and exporting excess electricity from their solar panel system back into the grid during peak demand periods.
3. Solar Credits: The Solar Credits program provides households and small business owners with an upfront discount when purchasing a new solar system, based on the amount of renewable energy generated by the system over its lifetime.
4. Tax Breaks: Small business owners may be able to claim tax deductions on certain expenses associated with installing a solar power system, including installation costs, maintenance expenses and interest payments related to financing arrangements taken out specifically for this purpose.
