Saint-Lazare, Quebec, Canada, located at latitude 45.3818 and longitude -74.1207, presents a mixed picture for solar PV energy generation throughout the year. This location in the Northern Temperate Zone experiences significant seasonal variations in solar output, which impacts the overall efficiency of solar installations.

Seasonal Solar Performance

The solar energy production at Saint-Lazare varies considerably across seasons. Summer stands out as the most productive period, with an impressive 5.92 kWh per day for each kilowatt of installed solar capacity. Spring follows closely behind, generating 5.40 kWh/day. However, there's a sharp decline in output during autumn (2.81 kWh/day) and winter (1.76 kWh/day).

These figures indicate that Saint-Lazare is most suitable for solar energy generation during the warmer months, from late spring through early fall. During this period, longer days and higher sun angles contribute to increased solar panel efficiency.

Optimal Panel Positioning

To maximize year-round solar production in Saint-Lazare, Quebec, fixed solar panels should be tilted at an angle of 39 degrees 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 could potentially impact solar production in Saint-Lazare:

1. Snow accumulation in winter, which can cover panels and reduce output
2. Cloudy weather, particularly common in autumn and winter

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 production even in less-than-ideal conditions.

While Saint-Lazare may not be the most ideal location for year-round solar energy production due to its significant seasonal variations, it still offers good potential, especially during the warmer months. With proper planning and installation techniques, solar PV can be a viable renewable energy option in this area.

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 Saint-Lazare

Seasonal solar PV output for Latitude: 45.3818, Longitude: -74.1207 (Saint-Lazare, 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-Lazare, Canada

To maximize your solar PV system's energy output in Saint-Lazare, Canada (Lat/Long 45.3818, -74.1207) 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-Lazare, 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-Lazare, 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-Lazare, 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-Lazare, 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 Saint-Lazare, Canada

The area around Saint-Lazare, Canada, located at 45.3818 degrees north latitude and 74.1207 degrees west longitude, is characterized by a gently rolling landscape typical of the Saint Lawrence Lowlands. This region features a mix of flat plains and low hills, with elevations generally ranging from 50 to 100 meters above sea level. The topography is largely shaped by glacial activity from the last ice age, resulting in a terrain dotted with small lakes, wetlands, and forested areas. Saint-Lazare itself sits on a slightly elevated plateau, with the surrounding countryside gradually sloping down towards the Ottawa and Saint Lawrence Rivers to the north and south, respectively. The area is part of the Vaudreuil-Soulanges region, known for its agricultural lands and pockets of suburban development.

Potential 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 be relatively flat, open areas with minimal shading from trees or buildings, and good access to existing electrical infrastructure. The agricultural lands to the south and southeast of Saint-Lazare present promising opportunities for solar PV development. These areas often feature large, open fields with minimal obstruction to sunlight. The flat terrain would make installation and maintenance of solar panels more straightforward and cost-effective. Another potentially suitable area lies to the west of Saint-Lazare, where there are expanses of cleared land that could accommodate large solar arrays. These locations benefit from being close to existing power transmission lines, which is crucial for connecting new solar installations to the grid. It's important to note that while the topography around Saint-Lazare is generally favorable for solar PV, specific site assessments would be necessary to determine the most optimal locations. Factors such as local zoning regulations, environmental considerations, and community acceptance would also play crucial roles in determining the feasibility of large-scale solar projects in the 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]
