Pembroke, Ontario, Canada presents a mixed profile for year-round solar energy generation, with significant seasonal variations that reflect its Northern Temperate Zone location at latitude 45.7466, longitude -77.2047.
Seasonal Solar Performance
The solar energy output at this location varies dramatically throughout the year. Summer provides the strongest performance at 5.89 kWh per day per kW of installed solar capacity, making it the peak season for solar generation. Spring follows as the second-best season with 5.19 kWh per day per kW, offering nearly comparable output to summer months. Autumn sees a notable decline to 2.82 kWh per day per kW, while winter presents the most challenging conditions with only 1.71 kWh per day per kW. This represents more than a three-fold difference between peak summer and winter production.Optimal Installation Configuration
For fixed panel installations at Pembroke, Ontario, the ideal tilt angle is 39 degrees facing south to maximize total year-round solar production. This angle is calculated to optimize energy capture across all seasons by accounting for the sun's varying position throughout the year and weighting the angles based on solar irradiance data.Local Factors Affecting Solar Production
Several environmental and weather factors in the Pembroke area can significantly impact solar energy generation:- Snow accumulation: Heavy winter snowfall can cover panels completely, blocking all solar production until cleared
- Ice formation: Freezing rain and ice storms can create thick ice layers on panels that are difficult to remove naturally
- Frequent cloud cover: The region experiences considerable cloudy weather, particularly during autumn and winter months
- Extreme temperature variations: Wide temperature swings can affect panel efficiency and component longevity
Preventative Measures for Enhanced Production
Several installation strategies can help mitigate these challenges and improve energy output:- Steeper tilt angles: Installing panels at angles steeper than the optimal 39 degrees can help snow slide off more easily, though this may slightly reduce overall annual production
- Heating systems: Installing panel heating elements or snow-melting systems can prevent ice buildup and clear snow more quickly
- Quality mounting systems: Using robust mounting hardware designed for extreme weather conditions ensures panels remain secure during storms
- Regular maintenance access: Designing installations with safe access for cleaning and snow removal during winter months
- Cold-weather optimized equipment: Selecting inverters and other components rated for extreme cold temperatures common in the region
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 Pembroke
Seasonal solar PV output for Latitude: 45.7466, Longitude: -77.2047 (Pembroke, 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 Pembroke, Canada
To maximize your solar PV system's energy output in Pembroke, Canada (Lat/Long 45.7466, -77.2047) 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 Pembroke, 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 Pembroke, 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 |
|---|---|---|---|
| 30° 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 Pembroke, 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 Pembroke, 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 Pembroke, Canada
Topographical Features Around Pembroke
The landscape surrounding Pembroke, Ontario presents a relatively gentle terrain characterized by rolling hills and modest elevation changes typical of the Canadian Shield's southeastern edge. The city sits at approximately 200 meters above sea level along the Ottawa River valley, which creates a natural corridor through the region. This river valley system has carved out broader, flatter areas that contrast with the surrounding uplands.
The immediate vicinity features a mix of forested hills, agricultural clearings, and wetland areas. The terrain gradually rises from the Ottawa River toward the interior, with elevations reaching 300 to 400 meters above sea level within a 20-kilometer radius. These elevation changes are generally gradual rather than steep, creating undulating countryside that rarely presents significant obstacles to development.
Rock outcroppings of Precambrian granite and gneiss appear throughout the area, though they are often covered by glacial deposits and organic soils. The region's geology includes areas of shallow soil over bedrock, particularly on hilltops and ridges, while deeper soils typically occur in valleys and depressions where sediments have accumulated over time.
Forest Cover and Land Use Patterns
Dense mixed forests dominate much of the landscape, consisting primarily of maple, birch, poplar, and coniferous species including pine, spruce, and fir. These forested areas create a patchwork pattern across the terrain, interspersed with cleared agricultural land, particularly in areas with better soils and gentler slopes.
Agricultural activities have historically focused on the flatter, more fertile areas, creating cleared zones that vary in size from small family farms to larger commercial operations. Pastureland for cattle and hay production represents a significant portion of the agricultural landscape, with some areas dedicated to crop production where soil conditions permit.
Optimal Areas for Large-Scale Solar Development
The most suitable locations for large-scale solar photovoltaic installations would be found in the cleared agricultural areas southeast and southwest of Pembroke, where the terrain is relatively flat and already free of forest cover. These areas offer gentle south-facing slopes that would be ideal for solar panel orientation while minimizing the need for extensive land clearing.
The agricultural zones along the Ottawa River valley present particularly attractive opportunities, as they combine favorable topography with existing cleared land and proximity to electrical infrastructure. Areas with elevations between 200 and 280 meters above sea level would be preferable, as they avoid both the potential for river valley fog and the steeper slopes found at higher elevations.
Former agricultural land that has transitioned to pasture or hay production would be especially well-suited for solar development, as these areas typically have established access roads and are already integrated into the local infrastructure network. The relatively open nature of the agricultural landscape also means that solar installations would face fewer shading issues from surrounding vegetation.
Areas to the west and northwest of Pembroke, while potentially suitable from a topographical standpoint, would require more extensive clearing of mature forest, making them less economically attractive for solar development. The ideal sites would be those that maximize the use of already-cleared land while taking advantage of the region's generally favorable terrain conditions.
Canada solar PV Stats as a country
