Solar PV Analysis of Kalgoorlie, Australia
Kalgoorlie, Western Australia, Australia is in a good location for generating energy through solar panels throughout the year. It's especially effective during the summer and spring, when there's more sunlight available. During these seasons, each kilowatt of installed solar can generate 8.75 and 7.41 kilowatt-hours per day respectively. Autumn and winter see less sunlight, so they'll produce less energy (5.35 and 3.92 kilowatt-hours per day respectively), but it's still a decent amount.
To get the most out of your solar panels in Kalgoorlie all year round, you should tilt them at an angle of 27 degrees facing north. This will help capture as much sunlight as possible throughout different times of the year.
When it comes to local factors that might affect solar production in Kalgoorlie, Western Australia, there aren't too many significant issues to worry about due to its relatively flat topography and consistent weather patterns with plenty of sunshine year-round.
However, like any other place on earth, dust accumulation on panels could be a concern as this can reduce their efficiency over time - regular cleaning can prevent this issue from becoming significant though.
Also keep in mind that while Kalgoorlie doesn't experience extreme weather events frequently like cyclones or hailstorms which could damage your installation physically or reduce output significantly due to cloud cover; occasional high temperature days (above 25C) might cause slight decrease in panel efficiency - but this would not be a major concern considering overall potential production levels here are quite high compared to many other places globally.
Overall then: if you're considering installing solar panels in Kalgoorlie – go for it! It’s an ideal location with lots of sun exposure for most parts of the year making it perfect for harnessing solar energy effectively.
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 Kalgoorlie
Seasonal solar PV output for Latitude: -30.749, Longitude: 121.466 (Kalgoorlie, 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 27° North in Kalgoorlie, Australia
To maximize your solar PV system's energy output in Kalgoorlie, Australia (Lat/Long -30.749, 121.466) throughout the year, you should tilt your panels at an angle of 27° 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 Kalgoorlie, 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 Kalgoorlie, Australia. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 27° North tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 15° North in Summer | 36° North in Autumn | 46° North in Winter | 24° 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 Kalgoorlie, 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 Kalgoorlie, 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 Kalgoorlie, Australia
Kalgoorlie, Australia is located in the Eastern Goldfields region of Western Australia. The topography is characterized by flat plains and arid desert landscapes with some low-lying hills. The region experiences a semi-arid climate, with hot summers and mild to cool winters.
As for the suitability for large-scale solar PV, the flat plains surrounding Kalgoorlie would be ideal due to their high levels of solar irradiation throughout most of the year. Moreover, these areas are relatively uninhabited which reduces potential conflicts over land use.
However, it's important to consider that although the area has a high potential for solar energy production due to its sunny climate, its remoteness could pose challenges in terms of grid connectivity and transportation of equipment and materials. Therefore, any large-scale solar project would need careful planning regarding these logistical aspects.
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.
