Solar PV Analysis of Sydney, Canada
Sydney, located in Nova Scotia, Canada, presents a mixed picture for year-round solar energy generation. Situated in the Northern Temperate Zone, this coastal city experiences significant seasonal variations in solar potential.
Seasonal Solar Performance
Summer stands out as the most productive season for solar energy in Sydney, with an impressive daily output of 5.83 kWh per kW of installed capacity. Spring follows closely, generating 4.70 kWh/day. However, autumn sees a substantial drop to 2.70 kWh/day, while winter performance plummets to a mere 1.37 kWh/day.
These figures highlight the stark contrast between the warm and cold seasons, with summer producing more than four times the energy of winter. The extended daylight hours and higher sun angles during summer months contribute significantly to this peak performance.
Optimal Panel Installation
To maximize year-round solar production in Sydney, fixed solar panels should be tilted at an angle of 39 degrees facing south. This optimal angle helps capture the most sunlight throughout the year, balancing the low winter sun with the high summer sun.
Environmental and Weather Factors
Several factors can impact solar production in Sydney:
- Snow accumulation in winter can reduce panel efficiency, necessitating regular clearing
- Coastal fog and cloud cover, especially in spring and fall, may diminish solar irradiance
To mitigate these issues, consider installing panels at a steeper angle to promote snow sliding and using high-efficiency panels that perform well in low-light conditions. Additionally, regular maintenance and cleaning can help ensure optimal performance year-round.
While Sydney's location presents challenges for consistent solar energy production, particularly in winter, the strong performance during spring and summer makes it a viable option for supplementing energy needs. With proper installation and maintenance, solar PV systems can still provide significant benefits to residents and businesses in this Canadian coastal city.
Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.
So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 569 locations across Canada. 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 Sydney
Seasonal solar PV output for Latitude: 46.131, Longitude: -60.1775 (Sydney, Canada), 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 39° South in Sydney, Canada
To maximize your solar PV system's energy output in Sydney, Canada (Lat/Long 46.131, -60.1775) throughout the year, you should tilt your panels at an angle of 39° South 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 Sydney, Canada
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 Sydney, Canada. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 39° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 30° South in Summer | 49° South in Autumn | 60° South in Winter | 38° South 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 Sydney, Canada
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 Sydney, Canada.
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 Sydney, Canada
Sydney, Canada, located on Cape Breton Island in Nova Scotia, is characterized by a diverse and picturesque topography. The area surrounding Sydney features a mix of coastal lowlands, rolling hills, and more rugged terrain as you move inland.
The immediate vicinity of Sydney is relatively flat, with gentle slopes leading down to the harbor. This coastal area is marked by sandy beaches, rocky shores, and small cliffs. As you move away from the coast, the landscape becomes more varied, with low hills and shallow valleys creating a gently undulating terrain.
Further inland, the topography becomes more pronounced, with higher hills and deeper valleys. The landscape is dotted with numerous lakes, rivers, and streams, which have carved their way through the terrain over time. The Bras d'Or Lake, a large inland sea, dominates much of the central part of Cape Breton Island and influences the surrounding topography.
To the northwest of Sydney, the land rises more dramatically as it approaches the highlands of Cape Breton, culminating in the Cape Breton Highlands National Park. This area features more rugged terrain with steep slopes, deep valleys, and plateaus.
Regarding areas suitable for large-scale solar PV installations, the most promising locations would be found in the flatter, open areas surrounding Sydney. The coastal lowlands and gently rolling hills to the south and east of the city offer potential sites with good sun exposure and minimal shading from natural features.
Specifically, the areas between Sydney and Glace Bay, as well as the region south of Sydney towards East Bay, could be well-suited for solar farms. These locations generally have fewer trees and more open space, which is ideal for maximizing solar energy capture. Additionally, the slightly elevated areas in these regions may benefit from reduced fog exposure compared to locations directly on the coast.
However, it's important to note that while the topography in these areas is favorable, other factors such as local climate conditions, existing land use, and proximity to electrical infrastructure would also need to be considered when determining the most suitable locations for large-scale solar PV installations.
Canada solar PV Stats as a country
Canada ranks 23rd in the world for cumulative solar PV capacity, with 3,630 total MW's of solar PV installed. This means that 0.70% of Canada's total energy as a country comes from solar PV (that's 38th in the world). Each year Canada is generating 96 Watts from solar PV per capita (Canada ranks 40th in the world for solar PV Watts generated per capita). [source]
