Solar PV Analysis of Brisbane, Australia
Brisbane, Queensland, Australia is a pretty good spot to generate electricity using solar panels all year round. The amount of energy you can get from the sun varies throughout the year. During summer, you can expect to get about 7.18 kilowatt-hours (kWh) for each kilowatt (kW) of solar panels you have installed per day. In autumn and winter, this drops to around 4.60 and 4.09 kWh/day respectively, but it picks up again in spring with an average of 6.29 kWh/day.
So if we look at these numbers, summer and spring are the best times of the year for generating solar power in Brisbane because there's more sunlight during those seasons.
If you're installing solar panels in Brisbane, Queensland, it's recommended that they be tilted at an angle of 25 degrees facing North for maximum efficiency over the whole year.
As for factors that might affect how much energy your solar panels can produce - Brisbane is generally sunny but there are some things to consider:
1) Weather: Heavy rain or cloud cover will reduce the amount of sunlight reaching your panels which means less electricity generated.
2) Dust and debris: If dust or other debris collects on your panels it could block some sunlight.
3) Shading: Buildings or trees casting shadows over your panels will also reduce their effectiveness.
To deal with these issues:
1) Regularly clean your solar panel surface so dust or other particles don't block out sunlight.
2) Try to install them where they won't be shaded by buildings or trees.
3) There’s not much one can do about weather conditions like heavy rain except ensuring proper installation so as not to damage them during such conditions.
Overall though, based on its location and climate conditions most times of the year, Brisbane is a great place for harnessing energy from the sun through photovoltaic (PV)solar power systems.
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 Brisbane
Seasonal solar PV output for Latitude: -27.4679, Longitude: 153.0325 (Brisbane, 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 Brisbane, Australia
To maximize your solar PV system's energy output in Brisbane, Australia (Lat/Long -27.4679, 153.0325) 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 Brisbane, 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 Brisbane, 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 |
|---|---|---|---|
| 11° North in Summer | 33° North in Autumn | 42° North in Winter | 21° 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 Brisbane, 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 Brisbane, 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 Brisbane, Australia
Brisbane, Australia is located in the southeastern corner of Queensland. The topography of Brisbane is characterized by its location on the Brisbane River and it is relatively hilly. The city is surrounded by a mix of rolling hills and low-lying floodplains.
The areas surrounding Brisbane that would be most suited for large-scale solar PV installations are those with high levels of sunlight and flat or gently sloping land for easy installation. Given these criteria, regions to the west and northwest of Brisbane such as Lockyer Valley, Somerset Region, and South Burnett Region could be suitable due to their more consistent sunlight exposure compared to coastal areas which can have more cloud cover.
However, it's worth noting that modern solar PV technology can also perform well in a variety of conditions including partial shade or cloudy conditions. Therefore other factors such as proximity to existing energy infrastructure (for connection to the grid), land use regulations, environmental considerations etc., would also play an important role in deciding where a large scale solar farm could potentially be located.
Remember that this analysis should ideally be complemented with detailed local studies considering all relevant variables including but not limited to sun irradiance data throughout different seasons or potential environmental impacts before making a decision about where to install large-scale solar PV systems.
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.
