Solar PV Analysis of Wallan, Australia
The location at Wallan, Victoria, Australia is quite suitable for generating energy through solar PV systems. However, the amount of energy you can generate varies significantly throughout the year.
In summer, you can expect to generate a lot of energy - about 7.57 kilowatt-hours (kWh) per day for each kilowatt (kW) of your solar installation. This is because the days are longer and sunnier during this season. In autumn and spring, you can still generate a decent amount of energy - around 3.92 kWh/day in Autumn and 5.76 kWh/day in Spring per kW installed.
However, winter could be challenging as there's less sunshine due to shorter days and more cloudy weather conditions; thus only producing around 2.48 kWh/day per kW installed.
To maximize your year-round solar production at this location, it's recommended that your panels are tilted at an angle of 32 degrees facing North.
As for local factors that might affect solar production in Wallan; topography or landscape features such as hills or trees may cast shadows on the panels reducing their efficiency especially if they're located towards the north where panels should ideally face to capture maximum sunlight in Australia.
Weather conditions such as frequent cloud cover or dust storms could also reduce solar panel effectiveness by blocking sunlight from reaching them directly.
To counter these potential issues:
1) Consider installing your system on high ground with minimal obstructions like tall buildings or trees.
2) Regular cleaning and maintenance would ensure dust or debris doesn't accumulate on your panels thereby ensuring they perform optimally.
3) If cloud cover is a significant issue then consider using bifacial modules which can capture sunlight from both sides thereby increasing overall efficiency even under cloudy skies.
Overall while there are challenges related to seasonal variations and potential local environmental factors; with proper planning & maintenance one can still successfully harness solar power effectively at Wallan 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 Wallan
Seasonal solar PV output for Latitude: -37.4066923, Longitude: 144.9798236 (Wallan, 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 32° North in Wallan, Australia
To maximize your solar PV system's energy output in Wallan, Australia (Lat/Long -37.4066923, 144.9798236) throughout the year, you should tilt your panels at an angle of 32° 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 Wallan, 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 Wallan, Australia. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 32° 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 | 42° North in Autumn | 52° North in Winter | 30° 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 Wallan, 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 Wallan, 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 Wallan, Australia
Wallan, Australia is characterized by a mix of flat and slightly hilly terrain. The region is in the state of Victoria, which has a diverse topography ranging from the flat, arid regions in the northwest to mountainous areas in the northeast and east.
For large-scale solar PV installations, relatively flat and open areas are most suitable as they allow for maximum exposure to sunlight and ease of installation. Areas with minimal shading from trees or buildings are also ideal.
In Wallan's vicinity, there seems to be plenty of such land particularly towards its north-west side where it appears less populated with more open spaces. However, specific site feasibility would still require detailed study including factors like local climate conditions (solar irradiation levels), land use restrictions, proximity to power transmission infrastructure etc.
It's worth noting that Victoria does not have as much sunshine as some other parts of Australia (like Western Australia or Queensland). However, this doesn't rule out solar power generation - Germany is one example where significant solar capacity has been installed despite having lower sunlight levels than many other countries.
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.
