Solar PV Analysis of Sydney, Australia
Sydney, New South Wales, Australia is a pretty good place to generate solar power year-round. The amount of energy you can get from the sun changes with the seasons. In summer, when the sun is out for longer and more directly overhead, you can expect to get about 6.73 kilowatt-hours (kWh) of energy per day for each kilowatt (kW) of solar panels you have installed. This drops to around 4.26 kWh/day in autumn and 3.37 kWh/day in winter when days are shorter and the sun is lower in the sky, but it goes back up to about 5.83 kWh/day in spring as we approach summer again.
The best time of year to generate solar power at this location would be during summer due to longer daylight hours and higher intensity sunlight hitting your panels more directly.
If you're setting up a fixed panel installation (where the panels don't move or track the sun), tilting them at an angle of 30 degrees facing North will give you maximum total energy production over a whole year.
There might be some local factors that could affect how much solar power you can produce though - things like weather conditions or physical features like mountains or buildings that could block sunlight from reaching your panels.
In Sydney, New South Wales, there's generally plenty of sunshine throughout most parts of the year but it does experience periods with rain and cloud cover which could reduce your solar output temporarily during those times especially during winter months when rainfall tends to be higher than other seasons.
To ensure greater energy production despite these factors, consider installing additional capacity so that even on less sunny days there's still enough generation happening; also regular cleaning/maintenance helps keep efficiency high as dust/grime build-up can reduce performance over time; another option might be considering advanced systems that include tracking mechanisms allowing panels to follow direction/movement of sun maximizing exposure & reducing impact from shading issues caused by nearby structures/trees.
Remember, solar power is a long-term investment and even with these considerations, Sydney's location and climate make it very suitable for solar energy generation.
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 Sydney
Seasonal solar PV output for Latitude: -33.8672, Longitude: 151.1997 (Sydney, 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 30° North in Sydney, Australia
To maximize your solar PV system's energy output in Sydney, Australia (Lat/Long -33.8672, 151.1997) throughout the year, you should tilt your panels at an angle of 30° 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 Sydney, 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 Sydney, Australia. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 30° 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 Sydney, 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 Sydney, 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 Sydney, Australia
Sydney, Australia is situated on the east coast of the country and is largely surrounded by a mix of coastal flatlands, plateaus, and small mountains. The city itself is located on a basin with the Pacific Ocean to its east. To the west lies the Blue Mountains with a rugged terrain and steep cliffs. The north and south are characterized by hilly landscapes.
The topography around Sydney can be challenging for large-scale solar PV installations due to these variations in landscape. However, there are still suitable areas for such installations:
1) Flatlands: Large-scale solar PV installations require vast expanses of relatively flat land which can be found in certain parts of Sydney's outskirts or in nearby regions.
2) Rooftops: Sydney has numerous industrial areas with large warehouse buildings that could house rooftop solar panels.
3) Landfills/Brownfields: These degraded lands can also be good sites for solar farms as they are often not suitable for other uses.
4) Rural Areas: Some rural areas outside of Sydney may have suitable land available that gets plenty of sunlight throughout the year. For example, regions towards central New South Wales (westwards from Sydney), where it's less mountainous could potentially accommodate larger scale solar farms.
The suitability would depend heavily on specific site characteristics like sun exposure (solar irradiance), local weather patterns, proximity to power grids or infrastructure for energy storage/transmission etc., which need detailed assessments.
It's also important to note that while physical topography plays a key role in determining suitability for large-scale Solar PV installations, other factors like land ownership rights, environmental impact considerations and local zoning laws/regulations also play crucial roles in determining feasibility.
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.
