Drummondville, Quebec, Canada, located at latitude 45.9061 and longitude -72.5929, presents a mixed picture for year-round solar PV energy generation. This Northern Temperate Zone location experiences significant seasonal variations in solar output, which impacts the overall efficiency of solar installations.

Seasonal Solar Performance

The solar energy production in Drummondville varies dramatically across the seasons. Summer stands out as the most productive period, with an impressive 5.84 kWh per day for each kilowatt of installed solar capacity. Spring follows closely behind, generating 5.22 kWh/day. However, the output drops considerably during autumn (2.77 kWh/day) and reaches its lowest point in winter (1.75 kWh/day).

Optimal Times for Solar Generation

Clearly, the late spring through early fall months offer the best conditions for solar energy production in Drummondville. This period, roughly from May to September, benefits from longer daylight hours and generally clearer skies, maximizing the potential of solar PV systems.

Panel Tilt Optimization

To maximize year-round solar production at this location, fixed solar panels should be tilted at an angle of 39 degrees facing south. This optimal angle helps balance energy capture across seasons, compensating for the sun's changing position throughout the year.

Environmental and Weather Factors

Drummondville's climate presents some challenges for solar energy production. The region experiences cold, snowy winters, which can significantly reduce solar output. Snow accumulation on panels can block sunlight, while shorter days and the sun's lower position in the sky further diminish energy generation.

To mitigate these issues, several preventative measures can be taken:

• Install panels at a steeper angle to encourage snow sliding off
• Use snow-shedding coatings on panels
• Implement a regular snow removal routine
• Consider bifacial panels to capture reflected light from snow

Additionally, the region's occasional heavy rainfall and cloudy days can temporarily reduce solar efficiency. However, these factors are less impactful than the winter conditions and don't require specific preventative measures beyond standard weatherproofing.

In conclusion, while Drummondville's location presents challenges for year-round solar energy production, particularly in winter, the strong performance during spring and summer months makes solar PV a viable option with proper planning and maintenance.

Solar output per kW of installed solar PV by season in Drummondville

Seasonal solar PV output for Latitude: 45.9061, Longitude: -72.5929 (Drummondville, 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 Drummondville, Canada

To maximize your solar PV system's energy output in Drummondville, Canada (Lat/Long 45.9061, -72.5929) 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 Drummondville, 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 Drummondville, 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	60° 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 Drummondville, 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 Drummondville, 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 Drummondville, Canada

The area surrounding Drummondville, Canada, located at latitude 45.9061 and longitude -72.5929, is characterized by a gently rolling landscape typical of the St. Lawrence Lowlands. This region features a mix of flat plains and low, undulating hills, creating a varied but generally mild topography. The city itself sits along the banks of the Saint-François River, which has shaped the local terrain over time. To the north and east of Drummondville, the land gradually rises towards the Appalachian foothills, introducing more pronounced hills and valleys. However, these elevations remain relatively modest compared to true mountain ranges. The southern and western areas maintain a flatter profile, with occasional gentle slopes and small plateaus. Throughout the region, the landscape is dotted with numerous small lakes, ponds, and streams, interspersed with forested areas and agricultural fields. This diverse terrain creates a patchwork of open spaces and wooded sections, contributing to the area's scenic beauty.

Suitable Areas for Large-Scale Solar PV

When considering locations for large-scale solar photovoltaic (PV) installations near Drummondville, several factors come into play. The most suitable areas would likely be found in the flatter, more open spaces to the south and west of the city. These regions offer several advantages for solar energy production: Firstly, the relatively level terrain in these areas would minimize the need for extensive land preparation, reducing installation costs and environmental impact. The open nature of the landscape also means fewer obstructions that could cast shadows on solar panels, maximizing their exposure to sunlight throughout the day. Additionally, many of these areas are currently used for agriculture, which could potentially allow for dual-use scenarios where solar installations coexist with certain types of farming activities. This approach, known as agrivoltaics, is gaining popularity in many regions. It's important to note that while the immediate vicinity of Drummondville may offer suitable locations, expanding the search radius further south and west into the broader St. Lawrence Lowlands could yield even more promising sites for large-scale solar PV projects. These areas tend to have more expansive flat terrain and potentially fewer competing land uses. However, any large-scale solar development would need to carefully consider local zoning regulations, environmental impact assessments, and grid connection capabilities. The proximity to existing electrical infrastructure and the capacity of the local grid to accommodate large influxes of solar-generated electricity would be crucial factors in determining the most viable locations for such projects.
