Truro, Nova Scotia, Canada, situated at 45.369° latitude and -63.263° longitude in the Northern Temperate Zone, presents a mixed landscape for solar energy generation throughout the year. The location experiences significant seasonal variations in solar output, which impacts the overall efficiency of photovoltaic (PV) systems.

Seasonal Solar Performance

Summer stands out as the prime season for solar energy production in Truro, Nova Scotia, with an impressive average of 5.87 kWh per day for each kilowatt of installed solar capacity. Spring follows closely, yielding 4.86 kWh/day. However, the colder months see a substantial decrease in solar output, with autumn generating 2.79 kWh/day and winter dropping to a mere 1.70 kWh/day.

This stark contrast between seasons indicates that solar energy systems in Truro will be most productive from late spring through early fall. During these months, longer daylight hours and higher sun angles contribute to increased energy generation.

Optimal Panel Installation

To maximize year-round solar production in Truro, Nova Scotia, fixed solar panels should be tilted at a 39-degree angle facing south. This orientation helps capture the most sunlight throughout the year, balancing the varying sun angles across seasons.

Environmental and Weather Considerations

Several factors can impact solar production in Truro:

1. Snow accumulation in winter can significantly reduce panel efficiency.
2. Frequent cloudy days, especially in autumn and winter, may limit solar exposure.

To mitigate these issues, consider installing panels at a steeper angle to encourage snow sliding off. Additionally, using high-efficiency panels and ensuring regular maintenance can help maximize output during less favorable conditions.

In conclusion, while Truro's location is not ideal for year-round solar production, it still offers substantial potential, particularly during the warmer months. With proper installation techniques and maintenance, solar PV systems can provide a valuable contribution to the area's renewable energy mix.

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 453 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 Truro

Seasonal solar PV output for Latitude: 45.369, Longitude: -63.263 (Truro, 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 Truro, Canada

To maximize your solar PV system's energy output in Truro, Canada (Lat/Long 45.369, -63.263) 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 Truro, 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 Truro, 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
29° South in Summer	49° South in Autumn	59° 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 Truro, 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 Truro, Canada.

Our calculation method

1. Solar Position:
   We determine the Sun's position on the Winter solstice using the location's latitude and solar declination.
2. Shadow Projection:
   We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle.
3. 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 Truro, Canada

The topography around Truro, Canada, located at latitude 45.369 and longitude -63.263, is characterized by a diverse landscape that includes both lowlands and rolling hills. Situated in the Colchester County of Nova Scotia, Truro lies at the eastern end of the Cobequid Bay, where the Salmon River meets the bay. The town itself is nestled in a valley, surrounded by gently sloping terrain that gradually rises to form the Cobequid Hills to the north. To the south and east of Truro, the land is relatively flat, consisting of fertile agricultural plains known as the Cobequid Shore lowlands. These areas were formed by glacial deposits and alluvial sediments from the nearby rivers. The flat terrain extends towards the Minas Basin, part of the Bay of Fundy, creating a picturesque coastal region. As one moves north and west from Truro, the landscape becomes more varied, with rolling hills and small valleys interspersed throughout the area. The Cobequid Hills, part of the Appalachian Mountain range, dominate the northern horizon, reaching elevations of up to 300 meters above sea level. These hills are primarily covered in mixed forests, adding to the region's natural beauty.

Areas Suitable for Large-scale Solar PV

When considering areas nearby that would be most suited to large-scale solar photovoltaic (PV) installations, several factors come into play. The ideal locations would have ample sunlight exposure, minimal shading, and relatively flat or gently sloping terrain to simplify installation and maintenance. The agricultural plains to the south and east of Truro present promising opportunities for solar PV development. These areas offer large, open spaces with minimal obstructions, allowing for maximum solar exposure throughout the day. The flat terrain would also facilitate easier installation and maintenance of solar panels. Some of the gently sloping hillsides to the north and west of Truro could also be suitable for solar PV installations. South-facing slopes, in particular, would receive optimal sunlight throughout the year. However, care would need to be taken to avoid areas with dense forest cover or steep gradients. It's important to note that while the topography around Truro offers potential for solar PV development, other factors such as local zoning regulations, environmental considerations, and proximity to electrical infrastructure would also need to be taken into account when selecting specific sites for large-scale solar projects.

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]
