Solar PV Analysis of Warwick, Australia
Warwick, Queensland, Australia is a decent location for generating solar energy throughout the year. The amount of energy produced from solar panels varies with the seasons, but it's generally higher in the warmer months. In summer, you can expect to generate about 7.10 kilowatt-hours (kWh) per day for each kilowatt (kW) of installed solar capacity. This decreases to around 4.65 kWh/day in autumn and further drops to around 4.06 kWh/day in winter, which is the lowest production period due to shorter daylight hours and less intense sunlight.
However, production picks up again in spring with an average daily output of about 6.04 kWh per kW of installed solar capacity.
To maximize your annual energy production from a fixed-panel installation at this location, you should tilt your panels at an angle of approximately 25 degrees facing North.
As for local factors that could affect your solar panel's performance: Warwick is known for its relatively clear skies and moderate rainfall which are favorable conditions for solar power generation.
However, it does experience some hail storms which could potentially damage your panels if they're not properly protected or built to withstand such weather conditions. To prevent this potential issue when installing your system, consider using durable materials and protective measures like hail guards or covers.
Also consider potential shading issues caused by trees or buildings that could block sunlight from reaching your panels especially during peak sun hours; ensure these are taken into account during site assessment prior to installation so as not to impede on optimal positioning and angling of the panels.
Lastly, keep in mind that regular maintenance such as cleaning dust or debris off the surface can also help ensure better energy production as dirty panels can reduce efficiency by up to 20%.
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 Warwick
Seasonal solar PV output for Latitude: -28.2137979, Longitude: 152.0306591 (Warwick, 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 Warwick, Australia
To maximize your solar PV system's energy output in Warwick, Australia (Lat/Long -28.2137979, 152.0306591) 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 Warwick, 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 Warwick, 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 Warwick, 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 Warwick, 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 Warwick, Australia
Warwick, Australia is located in the southeastern part of Queensland. The topography of the area is relatively flat with some gentle rolling hills. It is part of the Darling Downs region, which is known for its fertile soils and agricultural activities.
The climate in Warwick features a significant amount of sunshine throughout the year, making it potentially suitable for large-scale solar PV installations. However, specific suitability would depend on a variety of factors including land availability and use, proximity to electrical grid infrastructure, local planning regulations among others.
Areas that could be most suited for large-scale solar PV installations are typically open and flat lands with minimal shading and good sun exposure. In Warwick's case, unused or less productive agricultural lands could be potential sites given their flat terrain and exposure to sunlight.
However, it should be noted that using productive agricultural land for solar farms can sometimes be controversial due to competing land use priorities. Therefore any such decisions would need to take into account broader community interests and impacts on local farming activities.
Overall feasibility studies would need to be conducted before determining specific locations suitable for large scale solar PV installations in or around Warwick.
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.
