The location at Weston, New South Wales, Australia is pretty good for generating solar energy year-round. This is because it's located in the Southern Sub Tropics where there's a lot of sunshine. However, how much electricity you can generate from solar panels varies throughout the year.
In simpler terms, during summer you can expect to generate about 6.69 kilowatt-hours (kWh) of electricity per day for each kilowatt (kW) of solar panels installed. In autumn and winter, this drops to around 4.39 kWh/day and 3.44 kWh/day respectively due to shorter days and less sunlight intensity. But it picks up again in spring with an average output of around 5.92 kWh/day per kW.
So if you're planning on installing solar panels at this location, the best times for generating power would be summer and spring when sunlight is abundant.
To get the most out of your solar panel installation year-round at this location though, it’s ideal to tilt your panels towards north by approximately 30 degrees - that way they'll catch more sun over all four seasons.
As far as environmental or weather factors that could hinder your solar production here are concerned – well there aren't any significant ones really! The main thing would be ensuring your panels aren't shaded by trees or buildings which can reduce their output significantly.
However one factor that might affect overall performance could be dust build-up on the panels which can limit their efficiency over time - but regular cleaning should take care of this issue easily enough!
In conclusion: Weston NSW seems like a great place for producing clean renewable energy through solar power – just make sure your setup has been optimised properly for maximum productivity across all seasons.
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 Weston
Seasonal solar PV output for Latitude: -32.8148914, Longitude: 151.4588056 (Weston, 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 30° North in Weston, Australia
To maximize your solar PV system's energy output in Weston, Australia (Lat/Long -32.8148914, 151.4588056) throughout the year, you should tilt your panels at an angle of 30° 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 Weston, 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 Weston, Australia. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 30° 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 | 38° North in Autumn | 48° North in Winter | 25° 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 Weston, 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 Weston, 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 Weston, Australia
Weston is located in the Hunter Region of New South Wales, Australia. The topography around Weston is relatively flat to gently rolling, with some areas of hilly terrain. The region has a mix of urban, suburban and rural land uses, including residential areas, agricultural lands and natural bushland.
The region receives a good amount of sunlight throughout the year which makes it suitable for solar PV installations. Flat or gently sloping lands would be ideal for large-scale solar PV systems as they can maximize sun exposure.
Areas that are more suited to large-scale solar PV would be:
1. Open farmlands: These open spaces receive plenty of sunlight and have less shading from trees or buildings.
2. Industrial zones: Large rooftops or unused lands in industrial areas can be used for installing solar panels.
3. Brownfield sites: These are previously developed lands that are not currently in use could also potentially host large-scale solar farms.
4. Areas near power substations: Proximity to existing power infrastructure can reduce costs associated with connecting the solar farm to the grid.
It is important to consider factors such as local planning regulations, environmental impact assessments and community acceptance when identifying potential sites for large scale Solar PV projects.
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.
