Solar PV Analysis of Churchill, Australia
Churchill, Victoria, Australia is a decent location for generating energy through solar photovoltaic (PV) panels throughout the year. The amount of electricity produced by each kilowatt of installed solar power varies with the seasons.
In summer, when sunlight is most abundant, one can expect around 7.09 kilowatt-hours (kWh) per day for each kW of installed solar power. This makes summer an ideal time for generating solar energy at this location.
In autumn and winter, the output drops due to shorter days and less sunlight. In autumn you can expect around 3.64 kWh/day per kW of installed solar power and in winter it's even lower at about 2.41 kWh/day per kW.
Spring sees an increase again with approximately 5.57 kWh/day generated per kW of installed solar power as there are longer daylight hours compared to winter.
For optimal results from your solar panels in Churchill throughout the year, they should be tilted at an angle of 33 degrees facing northwards.
There might be some local factors that could affect your panel’s performance though - these include weather conditions like heavy rainfall or snow which could cover up your panels reducing their efficiency; dust or bird droppings that may accumulate on them over time; potential shading from nearby trees or buildings; and high winds that could potentially damage your installation if not properly secured.
To overcome these challenges:
1) Regular cleaning would help keep debris off the panels ensuring they perform optimally.
2) Trimming any overhanging branches or considering placement away from tall structures will reduce shading issues.
3) For areas prone to high winds having sturdy mounts and reinforcements would protect against wind damage.
4) If snowfall is common during winters consider installing systems that allow adjusting panel angles so they can be set steeper during those months enabling snow to slide off more easily.
So while Churchill isn't perfect for all-year-round maximum solar production, it's still a good location. With proper installation and maintenance, you can generate a decent amount of electricity from your solar panels throughout the year.
Note: The Southern Temperate Zone extends from -35° latitude South down to -66.5° 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 Churchill
Seasonal solar PV output for Latitude: -38.3126247, Longitude: 146.4197913 (Churchill, 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 33° North in Churchill, Australia
To maximize your solar PV system's energy output in Churchill, Australia (Lat/Long -38.3126247, 146.4197913) throughout the year, you should tilt your panels at an angle of 33° 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 Churchill, 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 Churchill, Australia. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 33° North tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 21° North in Summer | 43° North in Autumn | 52° North in Winter | 31° 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 Churchill, 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 Churchill, 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 Churchill, Australia
Churchill, Australia is located in the Latrobe Valley region of Victoria. The topography of this area is relatively flat with some gentle rolling hills. The region is known for its fertile agricultural lands and extensive coal reserves.
As for solar PV installations, flat areas are generally more suitable as they require less site preparation work and can accommodate larger arrays of panels. Given Churchill's topography, there are likely many suitable locations in the surrounding areas.
However, suitability for solar PV also depends on factors like sunlight levels and local climate conditions. Victoria has a temperate climate with reliable sunlight throughout the year, making it a good candidate for solar energy generation.
It's also worth noting that land use regulations and proximity to power grids or other infrastructure could affect where a large-scale solar installation could be placed. For instance, agricultural lands might not be available or ideal for such use due to potential conflicts with farming activities.
In terms of specific locations around Churchill that might be suited to large-scale solar PV installations, this would require detailed site surveys and feasibility studies by professionals in the field.
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.
