Autumn sees a moderate decrease in production, yielding 4.26 kWh daily. Winter, as expected, shows the lowest output at 3.37 kWh per day. This seasonal variation indicates that St Leonards is well-suited for solar energy production, particularly during the warmer months. The substantial difference between summer and winter outputs suggests that residents and businesses can expect significant energy savings during peak electricity demand periods in summer.Optimal Panel Installation
For those considering a fixed panel installation in St Leonards, the ideal angle to maximize year-round solar production is 30 degrees facing North. This tilt angle has been calculated to optimize energy capture across all seasons, taking into account the location's latitude and the Earth's elliptical orbit.Environmental and Local Factors
While St Leonards generally offers favorable conditions for solar energy production, there are some local factors that could potentially impact solar panel efficiency: 1. Urban development: The area's urban landscape may lead to shading issues from nearby buildings, potentially reducing solar exposure for some installations. 2. Coastal proximity: Being close to a large body of water can influence local weather patterns, possibly increasing humidity and salt exposure. 3. Varied topography: The mix of gentle slopes and steeper hills in the area may affect optimal panel placement and orientation. To mitigate these factors, several preventative measures can be taken during solar installation:- Conduct thorough site assessments to identify potential shading issues from buildings or trees.
- Use high-quality, corrosion-resistant materials to combat potential salt exposure from the nearby coast.
- Implement micro-inverters or power optimizers to minimize the impact of partial shading on overall system performance.
- Consider adjustable mounting systems to fine-tune panel angles based on specific site conditions.
Note: The Southern Sub Tropics extend from -23.5° latitude South down to -35° latitude.

Solar output per kW of installed solar PV by season in St Leonards
Seasonal solar PV output for Latitude: -33.8174, Longitude: 151.1938 (St Leonards, 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 St Leonards, Australia
To maximize your solar PV system's energy output in St Leonards, Australia (Lat/Long -33.8174, 151.1938) 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 St Leonards, 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 St Leonards, 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 St Leonards, 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 St Leonards, 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 St Leonards, Australia
St Leonards, Australia, located at latitude -33.8174 and longitude 151.1938, is situated in the Lower North Shore region of Sydney, New South Wales. The topography of the area is characterized by:
1. Hilly terrain: The area has a mix of gentle slopes and steeper hills.
2. Harbor proximity: St Leonards is close to Sydney Harbor, which influences the local topography.
3. Urban development: As part of the greater Sydney area, much of the land is developed with buildings and infrastructure.
4. Pockets of green spaces: There are some parks and reserves in the vicinity.
For large-scale solar PV installations, the most suitable areas nearby would likely be:
1. Western Sydney: The flatter, more open areas to the west of Sydney, such as parts of the Cumberland Plain, offer more space and potentially better solar exposure.
2. Rural areas outside Sydney: Locations further from the city center, particularly to the west and southwest, may have larger tracts of available land with fewer obstructions.
3. Industrial zones: Some industrial areas in the greater Sydney region might have large roof spaces suitable for solar installations.
4. Repurposed land: Former landfills or brownfield sites that have been remediated could be potential locations for solar farms.
It's important to note that the immediate area around St Leonards itself is not ideal for large-scale solar PV due to:
1. Limited open space: The urban nature of the area means there's little available land for large installations.
2. Shading from buildings: Tall structures in the area could cast shadows on potential solar sites.
3. Higher land values: The cost of land in this part of Sydney would likely make large-scale solar projects economically challenging.
4. Zoning restrictions: Local regulations may limit the ability to install large solar arrays in this predominantly residential and commercial area.
For the most suitable locations for large-scale solar PV, it would be best to look further out from the Sydney metropolitan area, where there is more open space, fewer obstructions, and potentially more favorable zoning for such projects.
