Solar PV Analysis of Murwillumbah, Australia
The location at Murwillumbah, New South Wales, Australia is pretty good for generating energy using solar panels all year round. During the different seasons of the year, you can expect varying amounts of energy to be produced by each kilowatt of solar power installed. In Summer, you can expect about 6.80kWh per day; in Autumn it drops a bit to around 4.43kWh per day; Winter sees a further drop to around 3.93kWh per day; and then it goes up again in Spring to about 5.96kWh per day.
Now if we talk about the best time of year for generating solar power at this location, that would be during Summer when the sun is out longer and stronger - giving you more bang for your buck from your solar panels.
If you're planning on installing fixed solar panels here, tilting them at an angle of 26 degrees towards North will give you maximum energy production throughout the year.
As far as local factors go that could hinder your solar production - there's nothing major to worry about in Murwillumbah. It's located in a tropical region which means plenty of sunshine throughout most parts of the year which is great for your solar panels!
However, just like any other place on Earth, weather conditions such as cloudy or rainy days could temporarily reduce your energy production but these are usually short-lived and shouldn't significantly affect your overall yearly output.
In terms of topography or geographical features that might block sunlight from reaching your panels (like large trees or buildings), these would need to be considered on a case-by-case basis depending on where exactly you're planning on installing them.
To prevent potential issues related with weather conditions or local obstacles blocking sunlight from reaching your panels: firstly make sure they are installed at an optimal site with minimal shading throughout the day and secondly ensure they are durable enough (or properly protected) to withstand local weather conditions - especially if the area is prone to heavy rain or storms. Regular cleaning and maintenance of the panels will also ensure they operate at optimum capacity.
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 490 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 Murwillumbah
Seasonal solar PV output for Latitude: -28.3273536, Longitude: 153.3958252 (Murwillumbah, 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 26° North in Murwillumbah, Australia
To maximize your solar PV system's energy output in Murwillumbah, Australia (Lat/Long -28.3273536, 153.3958252) throughout the year, you should tilt your panels at an angle of 26° 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 Murwillumbah, 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 Murwillumbah, Australia. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 26° 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 Murwillumbah, 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 Murwillumbah, 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 Murwillumbah, Australia
Murwillumbah, Australia is located in the Northern Rivers region of New South Wales. The topography of this area is characterized by a mix of flat lowlands and hilly terrain with Mount Warning (also known as Wollumbin) being a prominent feature in the landscape. The Tweed River flows through Murwillumbah, providing fertile alluvial soil for agriculture.
The climate in Murwillumbah is subtropical with high rainfall throughout the year but also receives ample sunshine. This makes it potentially suitable for solar PV installations. However, careful consideration would need to be given to site selection due to the varied topography and potential shading from hills and vegetation.
Flat areas with good sun exposure would be ideal for large-scale solar PV installations. These could potentially include agricultural lands or other open spaces that are not shaded by hills or trees. It's important that these sites are also close to existing power infrastructure for ease of connection.
However, any development would need to consider local environmental factors such as impacts on wildlife habitats and waterways, cultural heritage concerns (such as indigenous sacred sites), visual impacts on landscapes, flood risk in low-lying areas near the river, and potential loss of productive agricultural land.
It's recommended that a detailed feasibility study including site surveys and consultations with local communities and stakeholders should be conducted before any large-scale solar project is initiated in this area.
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]
