Solar PV Analysis of Saint-Constant, Canada
Saint-Constant, Quebec, Canada, located in the Northern Temperate Zone, presents a mixed picture for solar energy generation throughout the year. This location experiences significant seasonal variations in solar energy production, which affects the overall efficiency of solar PV systems.
Seasonal Solar Energy Production
The solar energy output at Saint-Constant varies considerably across the four seasons. Summer stands out as the most productive period, with an impressive 5.88 kWh per day for each kW of installed solar capacity. Spring follows closely behind, generating 5.27 kWh per day. However, there's a sharp decline in production during autumn and winter, with outputs of 2.84 kWh and 1.81 kWh per day, respectively.
Optimal Times for Solar Generation
The ideal times for solar energy production in Saint-Constant are clearly during the spring and summer months. These seasons offer longer daylight hours and more direct sunlight, resulting in significantly higher energy yields. The period from late March through September is particularly favorable for solar energy generation.
Panel Installation Considerations
For those installing fixed solar panels in Saint-Constant, Quebec, the optimal tilt angle to maximize year-round production is 39 degrees facing south. This angle helps to capture the most sunlight throughout the year, balancing the lower sun angle in winter with the higher angle in summer.
Environmental and Weather Factors
Several environmental and weather factors can impact solar energy production in Saint-Constant:
- Snow accumulation in winter can significantly reduce panel efficiency
- Cloudy and overcast conditions, common in autumn and winter, can decrease solar output
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, including snow removal, can help maintain better production levels during challenging periods.
While Saint-Constant's location isn't ideal for year-round solar energy production due to its harsh winters and variable weather, the strong performance in spring and summer makes solar PV systems a viable option. With proper planning and installation techniques, residents can still benefit significantly from solar energy, particularly during the more productive months of the year.
Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.

Solar output per kW of installed solar PV by season in Saint-Constant
Seasonal solar PV output for Latitude: 45.3696, Longitude: -73.5654 (Saint-Constant, 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 Saint-Constant, Canada
To maximize your solar PV system's energy output in Saint-Constant, Canada (Lat/Long 45.3696, -73.5654) 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 Saint-Constant, 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 Saint-Constant, 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 Saint-Constant, 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 Saint-Constant, 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 Saint-Constant, Canada
The topography around Saint-Constant, Canada, is generally flat to gently rolling. This area is part of the St. Lawrence Lowlands, a broad plain that stretches along the St. Lawrence River. The terrain is characterized by low-lying areas with occasional small hills and shallow valleys.
The landscape surrounding Saint-Constant is primarily agricultural, with vast open fields and scattered woodlots. The nearby Châteauguay River and its tributaries have carved shallow valleys into the otherwise level terrain. To the north and east, the land gradually slopes down towards the St. Lawrence River, while to the south and west, it remains relatively flat.
For large-scale solar PV installations, the areas most suited would be the open agricultural lands surrounding Saint-Constant. These flat or gently sloping fields offer several advantages for solar energy production:
- Minimal shading from natural features or buildings
- Easy access for construction and maintenance
- Ample space for large arrays of solar panels
- Existing road infrastructure for transportation of equipment
Specifically, the rural areas to the south and southwest of Saint-Constant would be particularly well-suited for solar PV projects. These locations offer large, uninterrupted stretches of flat land that receive good sun exposure throughout the day. The lack of significant elevation changes in these areas would simplify the installation process and reduce construction costs.
It's important to note that while the topography is favorable, other factors such as local zoning regulations, grid connection availability, and environmental considerations would also need to be taken into account when planning a large-scale solar PV installation in this region.
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]
