Solar PV Analysis of Yarram, Australia
The location at Yarram, Victoria, Australia is decent for year-round energy generation via solar photovoltaic (PV) systems. However, the effectiveness varies across different seasons.
During summer, you can expect to generate about 7.09 kilowatt-hours (kWh) per day for every kilowatt (kW) of installed solar power - this is a high level of production and makes summer an ideal time for solar energy generation here. Spring also offers good conditions with around 5.57 kWh/day produced per kW of installed solar.
However, during autumn and winter the efficiency drops significantly - to about 3.64 kWh/day in autumn and just 2.41 kWh/day in winter per kW of installed solar power.
To maximize the total annual production from a fixed panel installation at this location, it's recommended that panels are tilted at an angle of 33 degrees facing North.
As far as environmental or local factors that could impact solar production at this location - Yarram is situated within a temperate zone which means it experiences seasonal variations with cooler winters which can reduce sunlight exposure and thus affect productivity.
Additionally, the area may experience cloud cover or fog which could block sunlight from reaching the panels efficiently; these weather patterns are more prevalent during autumn and winter months causing lower output figures in these seasons.
Topographically speaking, if there are any hills or tall structures nearby that might cast shadows on your panels at certain times of day or year they could also impede your system's performance.
Preventative measures to ensure greater energy production include ensuring your panels are placed where they will receive maximum sun exposure throughout the year - avoiding shadow-casting obstacles where possible; regular cleaning and maintenance will also keep them working optimally by removing dust or debris that might obstruct sunlight absorption.
Remember though: while some factors may slightly reduce productivity in certain conditions overall Yarram still has potential as a viable location for solar energy generation.
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 Yarram
Seasonal solar PV output for Latitude: -38.5651486, Longitude: 146.6756928 (Yarram, 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 Yarram, Australia
To maximize your solar PV system's energy output in Yarram, Australia (Lat/Long -38.5651486, 146.6756928) 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 Yarram, 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 Yarram, 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 |
|---|---|---|---|
| 22° North in Summer | 43° North in Autumn | 53° 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 Yarram, 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 Yarram, 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 Yarram, Australia
Yarram, Australia is located in the South Gippsland region of Victoria. The area is characterized by rolling hills, valleys and plains. The landscape around Yarram includes a mixture of agricultural land, forests and coastal areas.
Regarding solar PV installations, flat or gently sloping lands are typically most suitable as they reduce installation costs and maximize sun exposure throughout the day. In the vicinity of Yarram, open agricultural lands could be potential sites for large-scale solar PV systems.
However, suitability for solar also depends on factors such as local climate (solar irradiance), land use restrictions (zoning laws), proximity to transmission lines (for grid-connected systems), environmental considerations etc.
In terms of climate, Yarram has a temperate oceanic climate with relatively high rainfall throughout the year which may affect solar panel efficiency.
Therefore detailed site-specific assessments would be needed to identify optimal locations for large-scale solar PV around Yarram.
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.
