Solar PV Analysis of Boulder, Australia
Boulder, Western Australia is a decent location for generating energy via solar PV throughout the year. The amount of energy that can be produced varies by season, with the highest output in summer at 8.75kWh/day per kW of installed solar and the lowest in winter at 3.92kWh/day per kW of installed solar. Autumn and spring offer moderate outputs at 5.35kWh/day and 7.41kWh/day per kW respectively.
The best time to generate solar power here would be during summer when sunlight is most abundant, followed by spring and autumn which provide a fair amount of sunlight too. Winter has less sunlight but you can still generate some power.
For maximum efficiency from your solar panels year-round, they should be fixed at an angle facing 27 degrees North as this will allow them to capture the most sunlight over the course of a year.
As for local factors that could affect solar production: Boulder is known for its hot summers and mild winters which are ideal conditions for generating solar power; however, it does experience some cloud cover throughout the year which could reduce output on certain days or periods.
Additionally, being located within a mining region there may also be dust issues that could potentially settle on panels reducing their efficiency over time if not regularly cleaned.
To mitigate these potential issues:
1) Regular cleaning can help maintain panel efficiency by removing dust build-up.
2) Consideration should also be given to installing tracking systems that adjust panel angles throughout the day to follow sun’s path thus maximizing exposure.
3) Using high quality panels designed to perform well under different light conditions including cloudy weather might also help increase overall annual yield.
4) Finally installing additional capacity (more panels or higher wattage ones) might compensate for days with lower production due to weather variations or other factors mentioned above.
In conclusion: While Boulder isn't perfect it's certainly feasible for producing good amounts of clean renewable energy via solar PV year-round.
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 Boulder
Seasonal solar PV output for Latitude: -30.7818811, Longitude: 121.4885929 (Boulder, 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 Boulder, Australia
To maximize your solar PV system's energy output in Boulder, Australia (Lat/Long -30.7818811, 121.4885929) 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 Boulder, 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 Boulder, 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 Boulder, 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 Boulder, 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 Boulder, Australia
Boulder, Australia is located in the region of Western Australia known as the Goldfields-Esperance region. The topography around Boulder is relatively flat to gently undulating, with some low hills and open plains. The area has a semi-arid climate with plenty of sunshine throughout the year.
The best areas for large-scale solar PV installations would be open, flat areas with minimal shading from trees or other structures. Given Boulder's location in a semi-arid region with plenty of sunlight, there are likely many suitable locations for solar farms in the surrounding area.
However, specific suitability would need to be assessed on a case-by-case basis taking into account factors such as land use restrictions, proximity to power grids and roads for access during construction and maintenance.
For example, some potential suitable areas include unused or abandoned mining sites which are already cleared of vegetation and could be repurposed for renewable energy generation. Additionally, any large industrial sites or commercial properties with significant roof space could also potentially host rooftop solar installations.
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.
