Top 10 Greenest Suburbs in Australia

Australia’s push towards sustainability is boldly marked by the solar installations sprouting up in suburbs across the nation. Using publicly available data from the Clean Energy Council (CEC), Solar Run calculated the total number of solar installations in every Australian suburb between January 2020 and December 2023.

Starting in 2020, the push for renewable energy was strong, with Roxburgh Park in Victoria marking a high with 2,550 installations, followed closely by Tarneit with 2,501. As we moved into 2021, Tarneit took the lead with a remarkable 3,366 installations. In 2022, Box Hill, NSW dethroned Tarneit with a year-end total of 1,957 installations.

2023 saw Tarneit (2,177 installations) reclaim the top position from Box Hill (2,152 installations), docking the latter to #2. Not to be outdone, suburbs like Mackay in Queensland and Caloundra also showcased impressive numbers. In Queensland, Bundaberg stood out with 1,735 installations. Nearby, Caloundra and Mackay proved to be vanguards of the solar movement, recording 1,651 and 1,502 installations respectively. Other notable suburbs included Roxburgh Park in Victoria and Maryborough in Queensland with 1,475 and 1,466 installations respectively. Kellyville followed closely with 1,442 installations.

From the four-year data, we observed:

2021 had the highest number of solar installations among the years analysed, with high installation rates per capita and increased monthly and seasonal installations.
2023 and 2020 also show high installation numbers, with 2023 demonstrating a slight decrease from 2021 but an increase compared to 2022.
The trend suggests a peak in 2021 followed by a drop in 2022, and a recovery in 2023, possibly due to the ramifications of COVID-19, the cost-of-living crisis, fluctuations in policy, economic factors, or public interest in renewable energy installations.

annual rankings by installation comparison 2020 2022

Going by the Top 10 totals, there was a higher rate of installations per capita in 2021 compared to other years. Here are the per capita installations for each year based on the population data:

2023: Approximately 61 installations per 100,000 people
2022: Approximately 58 installations per 100,000 people
2021: Approximately 89 installations per 100,000 people
2020: Approximately 76 installations per 100,000 people

average installations per capita

2021 had the highest monthly average, aligning with the per capita trend indicating a peak in renewable energy installations during that year. The average number of installations per month for each year is as follows:

2023: Approximately 1,365 installations
2022: Approximately 1,260 installations
2021: Approximately 1,841 installations
2020: Approximately 1,633 installations

average monthly installations

Solar installations appear to be higher in spring and summer compared to autumn and winter. This could be due to better weather conditions for installation during the warmer months and increased sunlight hours leading to greater perceived value for solar panels. Winter is also a popular time for installation because proactive homeowners wish to have their systems up and running by the time spring comes around. While there is some variation, overall solar installations seem to have decreased from 2021 to 2023. This could be owing to changes in government incentives or saturation in the market.

Seasonal installation between 2020 and 2023 was as follows:

2023: 3,976 in summer, 3,558 in autumn, 4,258 in winter, 4,563 in spring
2022: 3,611 in summer, 3,408 in autumn, 4,095 in winter, 4,006 in spring
2021: 5,368 in summer, 5,995 in autumn, 5,674 in winter, 5,055 in spring
2020: 5,414 in summer, 4,004 in autumn, 4,796 in winter, 5,390 in spring

average installation by seasons

The distribution of installations varies across states because of geographic size, population density, availability and attractiveness of rebates, and community initiatives. You see higher installations in Victoria’s Tarneit and Roxburgh Park, NSW’s Box Hill, and Queensland’s Bundaberg owing to the new housing estates, denser population and smaller geographical areas of these states compared to other like Western Australia and Northern Territory, which see different trends due to their demographics and landscapes.

Queensland leads with the highest number of installations at 54,365. Victoria follows with 51,104 solar installations. New South Wales comes in third with 48,470 installations. Western Australia is next with a total of 44,899 installations. In fifth place is the Australian Capital Territory with 22,803 installations. South Australia follows with 20,849 installations. Second to last, we have Northern Territory with 6,734 installations. Rounding out the list is Tasmania with 6,070 installations.

australias greenest states by renewable energy installations

Analysing the total renewable energy installations across Australian states from 2020 to 2023, combined with the contextual data on state areas and population, reveals interesting insights:

High Installation Numbers in High-Population States

Victoria and Queensland, with populations of 6.8 million and 5.4 million respectively, lead in installations. Despite Victoria having the smallest area among the states, its total installations are impressive at 51,104, which means there is a high level of urban renewable energy integration. Queensland, with a larger area but a smaller population compared to Victoria, still leads with 54,365 installations, indicating aggressive renewable energy policies and possibly more space for larger projects.

Installations vs Area and Population Density

Western Australia, the largest state by area, has a relatively lower population density (1.02 people per km²) and recorded 44,899 installations. Despite its vast area, the focus on renewable energy is considerable but not as intense per capita as in smaller but more densely populated states.

ACT, with the highest population density (171.4 people per km²) and the smallest area, shows a tremendous commitment to renewable energy with 22,803 installations. South Australia, though lagging behind the 786 times smaller ACT, has room for growth. Its lower figures could prompt state authorities and local governments to push for more attractive renewable energy policies.

Impact of Population Density on Renewable Energy Installation

States with lower population densities like NT and TAS have markedly fewer installations, at 6,734 and 6,070 respectively. These numbers reflect the challenges or perhaps lower urgency in spreading renewable energy infrastructure in less densely populated areas.

Conversely, states with moderate to high population densities such as NSW, VIC, and ACT show more robust installation figures, suggesting that higher population densities might drive bigger and better renewable energy initiatives.

Renewable Energy Policy Implications

The data suggests that states like Victoria, Queensland, and NSW are possibly leveraging their higher populations and economic activity to push for greater renewable energy adoption. This might be facilitated by both state-level policies and community initiatives oriented towards sustainability.

In contrast, the approach in vast but sparsely populated states like Western Australia and the Northern Territories may need to be different, focusing perhaps on community-specific projects or larger industrial installations that do not require dense population centres.

Future Focus

For future policymaking and planning, states with lower installation numbers but great potential (due to area or emerging economic growth) like Tasmania and Northern Territories might focus on targeted incentives to enhance renewable energy uptake.

The states with high installation numbers should continue to innovate and perhaps share best practices with less advanced states to promote a uniform national approach to renewable energy adoption.

Installation numbers fluctuate significantly from month to month and year to year in most suburbs, such as Upper Coomera and Mackay, which could be influenced by seasonal factors, promotional campaigns, or changes in local government incentives.

New Entrants and Exits

Some suburbs appear in the top 10 in certain years but not others. For instance, Mount Urah appears in the top 10 in 2020 but has lower rankings in subsequent years, indicating perhaps an initial surge followed by a plateau or decline in installation activities.

This trend of new entrants each year could reflect shifting focus areas for solar companies or changes in local policies that encourage installations in different suburbs.

Seasonal Peaks

There appears to be a trend of higher installations during the middle to the end of the year across several suburbs, possibly due to better weather conditions for installation or end-of-financial-year sales and incentives pushing for more installations.

Long-term Leaders

Caloundra and Bundaberg maintain high installation numbers and rankings throughout the years, suggesting these areas might have favourable conditions or policies for solar energy, making them attractive for continuous growth in installations.

Geographic Influence

Queensland’s large geographic area (1,729,742 m²) and extensive coastline (13,352 km) are likely contributing factors to its high number of installations. The abundant sunshine (around 8–9 hours daily) makes solar energy a particularly effective choice.

Adoption Spread

The broad spread of installations, from Bundaberg at the high end to Toolara Forest at the lower end of the top ten, indicates a robust uptake of solar installations across diverse regions. Notably, all top ten suburbs, have installations exceeding 1,000, except five instances over four years.

Impact of Sunshine

The high sunshine hours (8–9 hours/day) directly correlate with the number of installations, which means that Queensland’s natural climate advantages are being effectively utilised to promote solar energy solutions.

Local Campaigns and Infrastructure Development

The success of localised campaigns and the suitability of solar solutions in Queensland also suggest that regions with less developed traditional energy infrastructure are finding renewable energy to be a viable alternative. This is likely enhanced by state policies and incentives that promote solar energy adoption, especially in less densely populated areas.

Economic Considerations

The economic benefits of solar energy, combined with state incentives, are likely key drivers in the widespread adoption seen in Queensland. This is evident from the high engagement levels across the state, not just in metropolitan areas but also in more rural or remote locations.

Based on the data provided for the top 10 suburbs in Victoria from 2020 to 2023, here are some trends and observations regarding solar installations:

Total Installations

The total number of installations across the top ten suburbs in Victoria between 2020 and 2023 is 51,104.

Per Capita Installation

2023: 156 installations per 100,000 people
2022: 144 installations per 100,000 people
2021: 240 installations per 100,000 people
2020: 211 installations per 100,000 people

Growth in Total Installations

A general increase in total annual installations can be observed, especially in suburbs like Tarneit and Roxburgh Park. This could indicate growing acceptance and adoption of solar technology due to increasing awareness, government incentives, or rising electricity costs.

Consistent Leaders

Suburbs such as Tarneit and Roxburgh Park consistently appear at the top of the list across the years. This consistency could be attributed to demographic factors, economic growth, or local government policies supporting renewable energy.

Seasonal Variations

Installations generally peak during the later months of the year (October to December). This trend could be driven by end-of-year promotions, better weather for installations, or consumers acting on new budget cycles.

Fluctuations Across Suburbs

Some suburbs show more fluctuation in installation numbers year by year, such as Devon Meadows and Cardinia. These variations could be influenced by local developments, changes in the availability of installers, or varying levels of promotional activities.

The pronounced drop in installation numbers from Tarneit to Eynesbury in 2023 indicates that the adoption of solar installations is concentrated in specific areas.

Increasing Totals Over the Years

There is an observable increase in the total installations from 2020 to 2023 across almost all suburbs. This overall growth trend reflects a robust move towards solar energy, likely driven by both state and federal incentives, as well as a growing cultural shift towards sustainable living.

High Installation Rates in Newer Suburbs

Newer or rapidly developing suburbs like Werribee and Doreen are showing impressive numbers of installations. This indicates that newer residential developments are incorporating solar installations as a standard feature of new 7-star NatHERS homes.

Population and Area Dynamics

Victoria, with a population of 6.8 million and an area of 227,444 km², has a population density of 26.11 people per km². This higher density, compared to more sparsely populated states, influences the placement and adoption of solar installations, particularly in suburban areas.

Policy Influence

Victoria’s and Australia’s leading suburb, Tarneit, highlights the effectiveness of state policies and market conditions that particularly support renewable energy initiatives. This could be due to targeted subsidies, comprehensive urban planning policies, or community-led renewable energy projects.

Challenges and Opportunities in Urban Settings

Despite the high urban density, Victoria has managed to implement a high number of renewable energy solutions. This means the state is proactive in overcoming urban constraints like limited space and high property density.

Based on the data provided for the top 10 suburbs in New South Wales from 2020 to 2023, here are some observed trends regarding solar installations:

Total Installations

The total number of installations across the top ten suburbs in New South Wales between 2020 and 2023 is 48,470.

Per Capita Installation

2023: 144 installations per 100,000 people
2022: 131 installations per 100,000 people
2021: 155 installations per 100,000 people
2020: 154 installations per 100,000 people

Yearly Growth and Decline Patterns

Suburbs like Box Hill show a consistent increase in installations year over year, reaching a peak in 2023, which suggests a growing residential or commercial development conducive to solar installations.

Conversely, some suburbs like Camden show fluctuations with no clear upward or downward trend, indicating varying economic or regulatory impacts over the years.

NSW’s approach to solar installations showcases a more gradual decrease from the highest to the lowest in the top ten suburbs compared to Victoria (2023). This suggests a widespread acceptance and integration of solar technology across a variety of suburban settings within the state.

Seasonal Variability in Installations

There is a noticeable increase in installations during the later months of each year (from September to December), likely due to better weather conditions for installation or year-end financial incentives driving consumer behaviour.

Stability in Top Performers

Suburbs such as Box Hill and Kellyville consistently appear in the top ranks across the years. Their unwavering presence suggests robust local policies supporting solar energy, or these areas may have more new constructions that incorporate solar technology.

Variation in Total Installations

Total installations across the top 10 suburbs tend to increase each year, which could reflect broader state-wide initiatives to promote solar energy, improvements in solar technology making it more accessible, or increasing public awareness and acceptance of solar power as a viable energy source.

Impact of Local Factors

Suburbs with large year-to-year variations in installation numbers might be experiencing significant changes such as housing developments, changes in local government incentives, or economic fluctuations impacting consumer investment capabilities.

Population and Area Dynamics

With a population of 8.3 million and an area of 801,150 km², NSW has a population density of 9.52 people per km². This relatively high density influences the adoption and implementation of solar installations, especially in urban areas where space may be limited.

Urban Planning and Policy Influence

The high number of installations in suburbs like Box Hill indicates that state policies and market conditions are likely favourable for renewable energy projects. This is supported by NSW’s focus on integrating solar solutions in urban areas where traditional roof installations might be less feasible due to space constraints.

Comparison with Other States

Compared to Victoria, NSW has shown a higher per-suburb penetration of solar installations. This could be due to more aggressive renewable energy policies in NSW or a higher level of community engagement and awareness within the state.

Challenges in Urban Areas

The urban dynamics of NSW, particularly in Sydney and surrounding suburbs, present challenges such as fewer homeowners, limited roof space, lower sunshine hours (6–8/day), and a high number of rental properties. These factors might limit the feasibility of large-scale solar installations, pushing the focus towards smaller, more integrated solar solutions.

From the data provided for the top 10 suburbs in Western Australia regarding solar installations from 2020 to 2023, here are some key trends observed:

Total Installations

The total number of installations across the top ten suburbs in Western Australia between 2020 and 2023 is 44,899.

Per Capita Installation

2023: 314 installations per 100,000 people
2022: 337 installations per 100,000 people
2021: 443 installations per 100,000 people
2020: 455 installations per 100,000 people

Steady Growth in Suburbs

Some suburbs, such as Falcon and Bedfordale, show a consistent growth in solar installations over the years. This could be indicative of an increasing local interest in renewable energy solutions, possibly driven by community initiatives or state incentives. These efforts likely capitalise on the ample space available for large-scale installations, such as solar farms, which are more feasible in less densely populated areas.

Seasonal Fluctuations

The installation numbers across most suburbs exhibit variability from month to month within each year, with certain periods (typically the warmer months) seeing higher installation rates. This trend is possibly related to more favourable weather conditions for installations.

The spread of installations from Falcon to Willetton (2023) suggests that solar energy uptake is not uniformly distributed but is high in certain communities. This pattern may reflect the challenges and opportunities of deploying renewable energy solutions across large, sparsely populated areas.

High Peaks in Specific Months

Certain months, such as December and January, generally show higher installation numbers across multiple years. This could be due to end-of-year promotions, financial year tax incentives, or simply more suitable installation conditions during the summer months.

Year-Over-Year Variability

While some suburbs show growth, others like Aubin Grove and Henley Brook show fluctuations without a clear upward trend, suggesting that local factors or changes in market dynamics might significantly impact solar adoption rates.

Increasing Popularity in Certain Suburbs

Suburbs like Falcon and Bedfordale not only show growth but also have some of the highest total installations in certain years, highlighting them as hotspots for solar energy adoption in Western Australia.

Overall Increase in Installation Volumes

The total volume of installations across these top suburbs has generally increased from 2020 to 2023, suggesting a growing market for solar in the region, aligned with broader trends in Australia towards renewable energy solutions.

Population and Area Dynamics

Western Australia, with a sprawling area of 2,527,013 km² and a relatively modest population of 2.9 million, has a very low population density of 1.02 people per km². This vast area combined with low density affects the strategy and feasibility of widespread residential solar installation networks.

Policy and Economic Considerations

Western Australia’s higher per capita installations compared to more densely populated states indicate successful localised campaigns and possibly state-level incentives that make solar installations attractive and viable even in remote or rural settings.

Impact of Geographical and Climatic Factors

The state’s high average sunshine hours (8–9 hours daily) drive the adoption of solar energy. This consistent solar exposure makes it an ideal region for maximising the efficiency of solar panels, which in turn enhance the return on investment in solar technology.

Future Opportunities

Given Western Australia’s geographic characteristics, there is tremendous potential to expand solar energy projects, especially large-scale installations that can generate substantial amounts of renewable energy. Such developments could meet local energy demands and contribute to the state’s energy grid stability and sustainability.

Based on the data provided for the top 10 suburbs in the Australian Capital Territory (ACT) regarding solar installations from 2020 to 2023, here are some trends and insights:

Total Installations

The total number of installations across the top ten suburbs in the Australian Capital Territory between 2020 and 2023 is 22,803.

Per Capita Installation

There is a high density of installations in ACT, relative to its population size.

2023: 1,401 installations per 100,000 people
2022: 1,523 installations per 100,000 people
2021: 1,047 installations per 100,000 people
2020: 932 installations per 100,000 people

Overall Growth

There is a noticeable overall increase in solar installations over the years, particularly in suburbs like MacGregor and Fisher, which suggests growing acceptance and adoption of solar technology within the community. This could be due to increased local government incentives or a rising awareness of renewable energy benefits.

Seasonal and Yearly Variability

The installation numbers exhibit some variability across different months and years, with peaks typically occurring towards the end and beginning of the year. This pattern could be influenced by seasonal promotions, end-of-year incentives, or more favourable installation conditions during certain times of the year.

Top Performing and Emerging Suburbs

MacGregor consistently shows high installation numbers. This could indicate favourable socio-economic conditions, community initiatives, or local policies promoting solar energy use. Some suburbs like Nicholls and Calwell show fluctuations in their yearly totals but indicate a gradual increase over the years, suggesting slow but steady adoption rates that could accelerate with ongoing support and awareness campaigns.

Impact of Local Factors

Suburbs with lower total installations may be facing lower socio-economic conditions, less homeowner stability, or geographical limitations that could affect solar uptake. Targeted initiatives could help overcome these barriers.

Year-End Spikes

A common trend across most suburbs is an increase in installations towards the year’s end, possibly driven by residents trying to capitalise on rebates and tax incentives offered for renewable energy installations.

Population and Area Dynamics

ACT, with its compact area of 2,358 km² and a population of 465,000, has a high population density of 171.4 people per km². This density is a core factor that influences the strategy for deploying renewable energy installations in urban settings where space might be limited.

Installation Trends and Urban Planning

Although ACT is the smallest state, it has managed to be ahead of South Australia (417x its size), Northern Territory (572x its size), and Tasmania (29x its size). The spread of installations in ACT shows a robust integration of solar technology into urban residential areas, which is important in densely populated regions. The high per capita installations show that ACT’s renewable energy promotion endeavours in smaller, urbanised areas are successful.

Local Government Initiatives

ACT’s government has set ambitious targets for green infrastructure, including increasing canopy cover and promoting renewable energy, which align with its high rate of solar installations. These initiatives increase sustainability, improve liveability, and reduce environmental impact.

Impact of Climatic Factors

With 8–10 average daily hours of sunshine, ACT is well-positioned to take advantage of solar energy. The state’s consistent sunshine exposure can maximise the efficiency of solar installations, making solar energy a cost-effective and sustainable option to meet the community’s energy needs.

Based on the data provided for the top 10 suburbs in South Australia regarding solar installations from 2020 to 2023, here are some key observations and trends:

Total Installations

The total number of installations across the top ten suburbs in South Australia between 2020 and 2023 is 20,849.

Per Capita Installation

2023: 259 installations per 100,000 people
2022: 272 installations per 100,000 people
2021: 295 installations per 100,000 people
2020: 332 installations per 100,000 people

Steady Growth in Suburbs

Several suburbs such as Andrews Farm and Salisbury Downs have shown consistent growth or stability in solar installations over the years. This consistency likely reflects positive community responses to solar initiatives and ongoing local investments in renewable energy.

Variability in Installation Numbers

There are noticeable fluctuations in monthly installation numbers across the years for most suburbs. This variability could be influenced by seasonal factors, financial incentives, or changes in local government policies related to solar energy.

Year-End Increase

A common trend across multiple suburbs is an increase in installations towards the end of the year. This pattern may be due to residents taking advantage of year-end rebates and incentives, or simply more favourable weather conditions for installations during these months.

Emerging Suburbs

Suburbs like Wistow and Moana, while not always leading in total numbers, have shown tremendous growth rates, suggesting that solar uptake is becoming more widespread across different areas of South Australia.

Impact of Local Policies

The growth in installations in suburbs such as Woodcroft and Flagstaff Hill may reflect effective local policies promoting renewable energy, which suggests that the government’s efforts to influence solar adoption are successful in these areas. However, the modest number of installations in suburbs such as Wistow and Andrews Farm suggests that renewable energy projects in other South Australian communities may be driven more by local initiatives and community-led projects rather than widespread state-level campaigns. This is reflected in the concentrated pockets of higher installation numbers within certain suburbs.

Overall Increase in Installation

The total number of installations in the top 10 suburbs has increased over the years, indicating a broader acceptance and integration of solar technology within the state.

Population and Area Dynamics

South Australia, with an extensive area of 984,321 km² and a population of 1.8 million, has a low population density of 1.73 people per km². This low density impacts the distribution and feasibility of widespread solar installation networks across the state.

Challenges and Opportunities

Given the large geographic area and the relatively sparse population distribution, South Australia faces unique challenges in implementing widespread renewable energy solutions. However, these same factors also offer opportunities for large-scale solar farms and other renewable projects that can operate efficiently in less densely populated areas.

Economic and Environmental Considerations

Despite having fewer installations than the eastern states, the renewable energy adoption in leading suburbs indicates a high regional interest in renewable energy, which could be bolstered by state policies and incentives designed to increase renewable energy uptake.

Impact of Climatic Factors

With an average of 6 to 8 daily hours of sunshine, South Australia is well-positioned to utilise solar energy effectively. The consistent sunshine ensures efficiency and viability for solar energy projects.

Based on the data provided for the top 10 suburbs in the Northern Territory regarding solar installations from 2020 to 2023, here are some key observations and trends:

Total Installations

The total number of installations across the top ten suburbs in Northern Territory between 2020 and 2023 is 6,734.

Per Capita Installation

2023: 434 installations per 100,000 people
2022: 583 installations per 100,000 people
2021: 619 installations per 100,000 people
2020: 1,036 installations per 100,000 people

Gradual Increase in Installations

Suburbs such as Mitchell and Nightcliff show a consistent increase in solar installations over the years. This gradual increase could be indicative of growing awareness and acceptance of solar energy solutions within these communities.

High Variability Among Suburbs

There is intense variability in installation numbers across different suburbs, with some like Nightcliff and Mitchell consistently ranking high, whereas others like Knuckey Lagoon and Katherine have very few installations. This suggests that geographic, demographic, or socio-economic factors might be influencing solar adoption rates.

Seasonal Fluctuations

The installation numbers exhibit some seasonal variability, with many suburbs showing peaks at certain times of the year, potentially due to weather conditions being favourable for installations or end-of-year financial incentives.

Emergence of Smaller Suburbs

Smaller suburbs such as Girraween and Rum Jungle show fewer installations but maintain a presence in the top 10, which may indicate niche community initiatives or targeted local government support.

Year-end Peaks

A recurring trend is a peak in installations towards the end of the year across several suburbs. This could be driven by residents trying to capitalise on rebates and tax incentives offered for renewable energy installations before year-end.

Population and Area Dynamics

The Northern Territory, with an expansive area of 1,347,791 km² and a modest population of 252,000, has a very low population density of 0.18 people per km². This large area combined with sparse population influences the strategy and feasibility of widespread solar installation networks.

Challenges in Renewable Energy Adoption

Given the Northern Territory’s large geographic expanse and low population density, the focus on renewable energy installations tends to be on individual or isolated projects. This approach differs from more densely populated states where community-level renewable energy initiatives are more feasible.

Impact of Climatic and Geographical Factors

Despite having one of the highest sunshine exposures in Australia (9–10 hours daily), the Northern Territory has relatively lower total installations. This discrepancy may be influenced by less state focus or fewer incentives for renewable energy, coupled with logistical challenges in deploying and maintaining installations across such a large, sparsely populated area.

Opportunities for Growth

The abundant sunshine offers a substantial opportunity for the development of solar energy projects. However, strategic changes may be required in policy and community engagement to harness this potential fully. Enhancing infrastructure to support renewable energy and introducing more robust incentives could increase adoption rates.

Comparison with Other States

Compared to states like Victoria and New South Wales, where urban planning policies and subsidies boost renewable energy installations, the Northern Territory’s approach needs to adapt to its unique demographic and geographical context. The current low installation figures highlight the need for strategies that consider the territory’s vast area and low population density.

Based on the data provided for the top 10 suburbs in Tasmania from 2020 to 2023, here are some observed trends regarding solar installations:

Total Installations

The total number of installations across the top ten suburbs in Tasmania between 2020 and 2023 is 6,070.

Per Capita Installation

2023: 357 installations per 100,000 people
2022: 252 installations per 100,000 people
2021: 253 installations per 100,000 people
2020: 198 installations per 100,000 people

Installation Trends

Blackstone Heights has shown a consistent increase in solar installations over the years, with notable jumps each year. This suggests a growing trend towards renewable energy in this suburb.

Suburbs like Tranmere, East Devonport, and Sprent have shown gradual increases in solar installations year over year. This steady growth indicates a sustained interest in solar energy.

Lenah Valley and Recherche suburbs show more variable year-on-year changes, including some declines in installations. This variability could be influenced by factors such as local economic conditions, housing developments, or changes in local policies regarding renewable energy.

Kingston displayed a significant increase in solar installations in 2021 compared to 2020 but saw a drop in subsequent years. This might indicate an initial surge due to incentives or programs that may not have sustained.

Overall Increase in Solar Installations

The total number of installations has grown from 2020 to 2023, indicating an increasing acceptance and investment in solar technology across these top suburbs in Tasmania.

Population and Area Dynamics

Tasmania, with its area of 68,401 km² and a population of 573,000, has a population density of 7.55 people per km². This relatively low density, combined with a strong community engagement and state-level incentives, influences the strategy for deploying renewable energy installations.
