Saint-Eustache, Quebec, Canada, located at latitude 45.5789 and longitude -73.8818, 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 energy production.

Seasonal Solar Performance

Summer stands out as the most productive season, with an impressive 5.84 kWh per day for each kW of installed solar capacity. Spring follows closely behind, generating 5.22 kWh per day. These seasons offer ideal conditions for solar energy production, with longer days and higher sun angles.

However, the picture changes dramatically in autumn and winter. Autumn sees a significant drop to 2.77 kWh per day, while winter production plummets to just 1.75 kWh per day. This stark contrast highlights the challenges of year-round solar energy generation in Saint-Eustache.

Optimal Panel Positioning

To maximize year-round solar production, fixed panels should be tilted at a 39-degree angle facing south. This angle is calculated to capture the most sunlight throughout the year, considering the location's latitude and seasonal sun positions.

Environmental and Weather Factors

Several factors can impede solar production in Saint-Eustache:

• Snow accumulation in winter can significantly reduce panel efficiency
• Frequent cloud cover, especially in autumn and winter, can decrease solar irradiance

To mitigate these issues, consider installing panels at a steeper angle to promote snow sliding off. Additionally, using high-efficiency panels and implementing a regular cleaning schedule can help maintain optimal performance.

Conclusion

While Saint-Eustache's location is not ideal for year-round solar energy production, it still offers significant potential, especially during spring and summer. With proper planning and mitigation strategies, solar PV can be a viable renewable energy source for this area, despite the challenging winter months.

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-Eustache

Seasonal solar PV output for Latitude: 45.5789, Longitude: -73.8818 (Saint-Eustache, 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-Eustache, Canada

To maximize your solar PV system's energy output in Saint-Eustache, Canada (Lat/Long 45.5789, -73.8818) 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-Eustache, 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-Eustache, 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-Eustache, 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-Eustache, 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-Eustache, Canada

Saint-Eustache, located in southwestern Quebec, Canada, sits in a relatively flat area characterized by gently rolling terrain. The landscape surrounding the city is primarily composed of low-lying plains with occasional small hills and shallow valleys. This region is part of the larger St. Lawrence Lowlands, which features rich agricultural land and scattered woodlands. The topography of Saint-Eustache and its surroundings is influenced by the nearby Mille Îles River, which forms part of the Outaouais River system. This river has shaped the local landscape over time, creating subtle variations in elevation and contributing to the area's fertile soil. The terrain gradually slopes towards the river, with some areas experiencing minor flooding during spring thaws.

Solar PV Potential

When considering areas nearby that would be most suited for large-scale solar PV installations, several factors come into play. The relatively flat terrain surrounding Saint-Eustache offers advantages for solar development, as it reduces the need for extensive land preparation and allows for more efficient use of space. Agricultural lands to the north and east of Saint-Eustache present promising opportunities for solar PV projects. These open areas receive ample sunlight throughout the year and have minimal shading from natural or man-made structures. However, it's important to balance solar development with preserving valuable farmland. Some of the gently sloping areas to the south and southwest of Saint-Eustache could also be suitable for solar installations. These locations may benefit from slightly increased sun exposure due to their orientation, potentially improving the efficiency of solar panels. It's worth noting that while the topography around Saint-Eustache is generally favorable for solar PV, other factors such as local zoning regulations, grid connectivity, and environmental considerations would need to be carefully evaluated before implementing any 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]
