Solar PV Analysis of Inverell, Australia
Inverell, New South Wales, Australia is a pretty good place for generating solar energy throughout the year. However, there are some times of the year that are better than others. The amount of energy you can generate from solar panels depends on how much sunlight they get. In Inverell, during summer you can expect to generate about 7.57 kilowatt-hours per day for each kilowatt of solar panels installed. This drops to about 4.97 in autumn and even further to around 3.87 in winter before rising again to about 6.33 in spring.
This means that the best time of year for generating solar power in Inverell is during the summer and spring months when there's more sunlight available.
If you're installing fixed panel solar installations at this location, it's ideal to tilt your panels at an angle of 27 degrees facing north - this will help maximize your total energy production from your solar panels throughout the year.
As far as local factors go that might interfere with how much energy you can produce from your solar panels - these could include environmental factors like heavy rainfall or cloud cover which could limit the amount of sunlight reaching your panels; topographical factors like mountains or tall buildings casting shadows over your installation; or other local weather conditions like dust storms which could dirty your panels and reduce their efficiency.
To mitigate some of these issues, it would be a good idea to install a system for cleaning and maintaining your solar panels (for example, by having them cleaned regularly especially after dust storms), and if possible choose a location for installation where shadows from nearby structures won't fall on them (especially during peak sun hours). Regular maintenance checks will also ensure any technical issues are addressed promptly so they don't affect long-term productivity.
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 Inverell
Seasonal solar PV output for Latitude: -29.7739244, Longitude: 151.1114386 (Inverell, 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 Inverell, Australia
To maximize your solar PV system's energy output in Inverell, Australia (Lat/Long -29.7739244, 151.1114386) 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 Inverell, 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 Inverell, 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 |
|---|---|---|---|
| 14° North in Summer | 36° North in Autumn | 45° 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 Inverell, 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 Inverell, 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 Inverell, Australia
Inverell, Australia is located in the Northern Tablelands region of New South Wales. The topography of this area is characterized by rolling hills, valleys, and plateaus with elevations ranging from 200 to 1,300 meters above sea level. The land is largely used for agriculture including grazing and cropping.
Regarding large-scale solar PV installations, flat or gently sloping areas are generally preferred as they minimize the cost of installation and maximize efficiency. Given Inverell's topography and its abundant sunshine (it experiences more than 100 clear days per year), there are likely several suitable locations for solar farms in the region.
However, specific site selection would require a detailed assessment considering factors such as access to transmission lines, distance from load centers (cities or industries that consume electricity), land use restrictions (such as protected areas or prime agricultural land), local community acceptance among others.
It's worth noting that Inverell already has a significant presence in the renewable energy sector with Sapphire Wind Farm - one of Australia’s largest wind farms - located nearby. Moreover, the Australian Renewable Energy Agency (ARENA) has funded a large scale solar farm in Inverell which further suggests suitability for such developments.
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.
