Solar PV Analysis of Legana, Australia
Legana, Tasmania, Australia is a fairly decent location for generating solar energy year-round. However, the amount of energy produced varies significantly depending on the season.
In summer, you can expect to generate around 7.43 kilowatt-hours (kWh) per day for each kilowatt (kW) of installed solar panels. This is the best time of year for solar production at this location due to longer daylight hours and more direct sunlight.
Autumn sees a drop in production to about 3.71 kWh/day per kW due to shorter daylight hours and less intense sunlight as compared with summer.
Winter has the lowest production rate at only 2.07 kWh/day per kW because of even shorter days and less sunlight intensity.
Spring brings an increase in production again with about 5.52 kWh/day per kW thanks to longer daylight hours and more direct sun rays compared with winter.
To maximize your total yearly energy output from your solar panels in Legana, it's recommended that fixed panel installations be tilted at an angle of 35 degrees facing North.
As far as local factors which might affect your solar power generation goes; Legana is located within a temperate zone which experiences four distinct seasons including relatively cold winters that may sometimes include snowfall or heavy cloud cover - both can reduce solar panel efficiency by blocking sunlight reaching them directly.
Additionally, Tasmania being an island also means it's subject to frequent rainfall and high humidity levels which could potentially impact the performance of your panels by creating a layer of moisture on their surface thereby reducing their ability to absorb sunlight efficiently.
To counter these potential issues:
1) You might want to consider installing adjustable tilt mounts for your panels so you can change their angle based on seasonality – tilting them more towards the sun during winter months when sun rays are less direct will help optimize their performance.
2) Regular maintenance like cleaning off any snow or debris from your panels, and ensuring they are free from moisture or dampness will also help in maintaining their efficiency year-round.
3) Lastly, installing a sufficient number of panels to offset the lower production during winter months might be something worth considering. This way you can ensure that you generate enough power throughout the year despite seasonal variations.
Note: The Southern Temperate Zone extends from -35° latitude South down to -66.5° 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 Legana
Seasonal solar PV output for Latitude: -41.3647346, Longitude: 147.0403447 (Legana, 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 35° North in Legana, Australia
To maximize your solar PV system's energy output in Legana, Australia (Lat/Long -41.3647346, 147.0403447) throughout the year, you should tilt your panels at an angle of 35° 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 Legana, 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 Legana, Australia. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 35° North tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 25° North in Summer | 46° North in Autumn | 56° North in Winter | 34° 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 Legana, 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 Legana, 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 Legana, Australia
Legana is located in the Tamar Valley of Northern Tasmania, Australia. The topography is characterized by a mix of flat and slightly hilly terrains, with the Tamar River running through it. The region is known for its fertile soils and mild climate, making it ideal for agriculture.
As for solar PV suitability, areas with flat terrain and high sun exposure would be most suited. Given Legana's relatively mild and sunny climate, large-scale solar PV could potentially be viable in the region. However, specific suitability would depend on a detailed assessment considering factors like land use restrictions (e.g., agricultural or conservation lands), proximity to power grid infrastructure for connectivity etc.
In terms of nearby areas that might be suitable, potential locations could include less densely populated regions or unused farmlands along the Tamar Valley where there may be fewer land use conflicts. It should also be noted that while Tasmania generally receives less sunlight compared to mainland Australia due to its southern latitude position which can impact overall solar efficiency levels.
It's important to conduct thorough site assessments before deciding on a location for large-scale solar installations as many factors can influence viability including local weather conditions (solar irradiance), topography (slope/aspect), soil stability etc.
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]
