Solar PV Analysis of Gold Coast, Australia
The Gold Coast in Australia is a pretty good place for generating solar energy all year round. The sun shines more during some parts of the year than others, so you get more energy from your solar panels in those times.
In simple terms, the amount of energy you can expect to get from each kilowatt (kW) of solar panels installed at this location changes with the seasons. In summer, it's highest at 6.80 kilowatt-hours (kWh) per day. In autumn and winter, it drops to 4.43 kWh and 3.93 kWh per day respectively but picks up again in spring to 5.96 kWh/day.
So if you're thinking about when's the best time to generate solar power at this location, summer would be ideal because that's when you'll get the most energy out of your panels.
For fixed panel installations here, tilting them at an angle of 25 degrees towards North will help you make the most out of them throughout the year.
As for factors that could affect how much energy your panels produce - things like environmental conditions or local weather patterns - there are a few potential issues on the Gold Coast but they're not major ones.
Firstly, since it's located near the coast and has a subtropical climate with high humidity levels and frequent rainfall especially during summer months can temporarily reduce sunlight exposure which is necessary for optimal solar production
Secondly, while topography isn't really an issue as most areas on Gold Coast are flat or gently sloping making installation easier; structures such as tall buildings or trees might cast shadows on your panels reducing their efficiency if not properly accounted for during installation planning phase
To mitigate these issues:
1) Ensure that your system is designed with adequate protection against moisture damage due to high humidity levels.
2) Make sure that your system is cleaned regularly so any dirt or debris accumulated due to rainfall doesn't block sunlight.
3) Before installing your panels, consider the location carefully to avoid shadows from nearby structures. If that's not possible, you might want to consider using micro-inverters or power optimizers which can help individual panels perform better even when some are shaded.
In conclusion, while there are a few potential issues to be aware of, with proper planning and maintenance Gold Coast is a good place for solar energy production 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 Gold Coast
Seasonal solar PV output for Latitude: -28.016667, Longitude: 153.4 (Gold Coast, 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 25° North in Gold Coast, Australia
To maximize your solar PV system's energy output in Gold Coast, Australia (Lat/Long -28.016667, 153.4) throughout the year, you should tilt your panels at an angle of 25° 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 Gold Coast, 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 Gold Coast, Australia. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 25° North tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 12° North in Summer | 34° North in Autumn | 43° North in Winter | 22° 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 Gold Coast, 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 Gold Coast, 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 Gold Coast, Australia
The Gold Coast, Australia, is located in the southeastern corner of Queensland and is known for its beautiful coastline featuring long sandy beaches. The area has a diverse topography with coastal plains that rise up to meet mountainous terrain and plateaus towards the hinterland areas. These include elevated areas such as Mount Tamborine, Springbrook Plateau and Lamington Plateau, which are part of the Great Dividing Range.
For large-scale solar photovoltaic (PV) installations, flat or gently sloping terrains are generally preferred as they require less groundwork preparation and can accommodate more PV panels per unit area. Therefore, the coastal plains around Gold Coast would be more suitable for this purpose than the mountainous regions.
However, factors other than topography also need to be considered for large-scale solar PV installations. These include solar irradiance levels (the amount of sunlight available), land use restrictions or protections (such as national parks or residential areas), proximity to infrastructure like roads and power grids for accessibility and energy transmission purposes.
In terms of solar irradiance levels, Australia has some of the highest in the world with Queensland particularly well suited due to its tropical climate. The region westward from Gold Coast city towards Beaudesert could potentially be a good location considering both topographical suitability and high sunlight availability.
It's important to note that any specific project would require detailed feasibility studies taking into account all these factors along with environmental impact assessments 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.
