Solar PV Analysis of Griffith, Australia
Griffith, New South Wales, Australia is a fairly good location for year-round solar energy production because it receives a decent amount of sunlight throughout the year. The energy that can be generated from solar panels changes with each season. In summer, you can expect to generate about 8.47 kilowatt-hours (kWh) per day for every kilowatt (kW) of installed solar power. This reduces to 4.89 kWh/day in autumn and even further to 3.08 kWh/day in winter due to shorter days and less direct sunlight during these seasons. However, the amount increases again in spring, reaching about 6.31 kWh/day per kW.
Given these numbers, the most efficient times of year for generating solar energy at this location are during summer and spring when there's more sunlight available.
If you're installing fixed panel solar systems at this location, it's best to tilt the panels at an angle of 30 degrees facing northwards as this will maximise your total yearly production from your system.
As far as local factors that could affect your solar production are concerned, Griffith is located within a region known for its hot summers and mild winters which makes it quite ideal for solar power generation overall.
However, there might be some potential issues such as dust or dirt accumulation on the panels due to dry weather conditions or agriculture activities nearby which could reduce their efficiency over time if not cleaned regularly; shading from nearby buildings or trees might also affect how much sunlight reaches your panels; lastly extreme weather events such as hailstorms could potentially damage your system although these occurrences are rare.
To mitigate against these potential obstacles: regular cleaning of the panel surfaces can help maintain efficiency by removing any dust or dirt build-up; careful site selection and planning can avoid shading issues - ideally install panels where they will get unobstructed sun exposure throughout the day; finally using robust mounting systems and protective measures like hail guards could protect your system from weather-related damage.
Overall, with the right setup and maintenance, Griffith, New South Wales, Australia can be a very effective location for solar power generation.
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 Griffith
Seasonal solar PV output for Latitude: -34.2886639, Longitude: 146.0323982 (Griffith, 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 Griffith, Australia
To maximize your solar PV system's energy output in Griffith, Australia (Lat/Long -34.2886639, 146.0323982) 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 Griffith, 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 Griffith, 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 |
|---|---|---|---|
| 18° North in Summer | 39° North in Autumn | 49° North in Winter | 28° 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 Griffith, 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 Griffith, 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 Griffith, Australia
Griffith, Australia is located in the Riverina region of New South Wales. The topography around Griffith is generally flat with a slight slope towards the south-east. The region primarily consists of agricultural land, with vineyards and orchards being common.
The climate in Griffith is semi-arid, characterized by hot summers and mild winters. It receives a good amount of sunlight throughout the year which makes it suitable for large-scale solar PV installations.
The most suited areas nearby for large-scale solar PV would be on flat open lands that get maximum sun exposure and are relatively free from obstructions like tall buildings or trees that could cause shading issues. Given its agricultural nature, it would also be possible to integrate solar farming with existing farming practices - this concept known as agri-voltaics can help maximize land use efficiency while providing additional income streams for farmers.
However, any development should also consider potential impacts on local ecosystems and biodiversity. A thorough environmental impact assessment should be conducted before proceeding with large-scale installations.
It's also important to note that proximity to existing power infrastructure (like substations) can greatly influence the feasibility and cost-effectiveness of a project because it reduces connection costs.
Finally, social acceptance by local communities is another key factor when planning such projects – engaging stakeholders early in the process can help address concerns and build support for renewable energy projects.
Australia solar PV Stats as a country
