Hull, Quebec, Canada, located at 45.4783, -75.7041 in the Northern Temperate Zone, experiences significant seasonal variations in solar energy production potential throughout the year. This location demonstrates the typical pattern of northern hemisphere solar generation with distinct peaks and valleys across seasons.

Seasonal Solar Production

Solar PV panels in Hull produce their highest output during summer months, generating approximately 5.92kWh per day for each kilowatt of installed capacity. Spring follows closely behind with 5.40kWh/day per kW. Production drops considerably in autumn to 2.81kWh/day per kW, and reaches its lowest point in winter with just 1.76kWh/day per kW of installed capacity.

This seasonal pattern means Hull experiences more than three times the solar production in summer compared to winter months. The location is moderately suitable for solar energy, with excellent production during the warmer half of the year but significant challenges during colder months.

Optimal Installation Angle

For fixed solar panel installations in Hull, Quebec, the ideal tilt angle to maximize year-round energy production is 39 degrees facing South. This angle represents the mathematically optimal position to capture the most solar energy across all seasons, considering the location's latitude and seasonal sun paths.

Environmental and Weather Considerations

Several factors can impact solar production in Hull. Winter snow accumulation is perhaps the most significant challenge, as snow covering panels can drastically reduce or eliminate energy production. Snow can persist on panels for extended periods during the winter months when production is already at its lowest.

Hull also experiences cloudy conditions throughout the year, particularly during fall and winter, further reducing solar potential during these seasons. The region's freeze-thaw cycles and occasional ice storms can also temporarily impact production.

Preventative Measures

To maximize solar production in Hull despite these challenges, several preventative measures can be implemented:

• Install panels at the recommended 39-degree tilt, which not only optimizes year-round production but also helps shed snow more effectively than flatter installations
• Consider snow removal systems or accessibility for manual clearing during winter months
• Use high-efficiency panels rated for colder climates, as some panels perform better in lower temperatures
• Implement micro-inverters or power optimizers to minimize the impact when portions of the array are shaded or snow-covered
• Ensure robust mounting systems that can withstand potential ice loading and regional wind conditions

With these considerations in mind, a properly designed solar PV system in Hull can still provide significant energy production, particularly from March through October when conditions are most favorable.

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 Hull

Seasonal solar PV output for Latitude: 45.4783, Longitude: -75.7041 (Hull, 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 Hull, Canada

To maximize your solar PV system's energy output in Hull, Canada (Lat/Long 45.4783, -75.7041) 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 Hull, 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 Hull, 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 Hull, 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 Hull, 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 Hull, Canada

The landscape around Hull, Quebec (now part of the city of Gatineau) presents a varied topography characteristic of the transitional zone between the Canadian Shield and the St. Lawrence Lowlands. Hull is situated along the northern bank of the Ottawa River, directly across from Ottawa, Canada's capital city. The terrain in this region is generally characterized by gentle to moderate slopes with some notable features that influence its suitability for solar energy projects. The area surrounding Hull includes a mix of urban development, parkland, and some remaining agricultural spaces. Moving northward from the Ottawa River, the terrain gradually rises into rolling hills that represent the southernmost edge of the Gatineau Hills, part of the Canadian Shield. These hills become more pronounced as one moves further north into Gatineau Park, where elevations can reach over 300 meters above sea level.

Key Topographical Features

The Ottawa River forms a significant natural boundary to the south of Hull, with its wide valley creating relatively flat floodplains in some areas. The urban core of Hull/Gatineau occupies much of the flatter terrain near the river, with residential and commercial development extending outward. The transition from the flatter riverfront areas to the more elevated Canadian Shield creates a variety of slopes with different aspects (the direction they face). South-facing slopes in the region receive more direct sunlight throughout the year in the Northern Hemisphere, making them potentially valuable for solar energy collection. Several smaller waterways intersect the region, including the Gatineau River which joins the Ottawa River in Hull, creating additional valleys and drainage patterns that influence the local topography.

Optimal Areas for Solar PV Development

For large-scale solar photovoltaic (PV) installations, several areas around Hull present favorable conditions based on topographical considerations: The flatter agricultural lands to the east of Hull, extending toward Cumberland and beyond, offer significant potential. These areas feature relatively level terrain with minimal shading from topographical features, allowing for efficient arrangement of solar panels. The open nature of these lands means fewer obstacles to block sunlight throughout the day. Some of the gently sloping, south-facing hillsides north of Hull but before the more dramatic rises of Gatineau Park could be suitable locations. These areas benefit from their favorable aspect, receiving direct sunlight for extended periods while still being accessible for construction and maintenance. Former industrial lands and brownfield sites within the urban fabric of Hull/Gatineau that have suitable exposure could be repurposed for solar development, though these would likely be medium-scale rather than truly large installations. The plateaus and less steep sections of the Gatineau Hills with southern exposure present interesting opportunities, though development here would need to balance with conservation priorities as much of this area falls within protected parkland.

Topographical Limitations

Despite these opportunities, certain topographical features around Hull do present challenges for solar PV development. The increasing elevation and forest cover of the Gatineau Hills to the north create significant shading in some areas, particularly during winter months when the sun angle is lower. The hills themselves, while providing some good south-facing slopes, also include many north-facing slopes that would be unsuitable for solar installation. The urban density of Hull itself limits large-scale installations within the city proper, though rooftop solar remains viable on an individual building basis. Additionally, the river valleys can experience more fog and mist than higher elevations, potentially reducing solar efficiency in these locations during certain weather conditions. Seasonal considerations are also important - the topography interacts with the region's northern latitude to create significant variations in sun angle throughout the year, affecting optimal panel placement and expected energy production.

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.
