Alberta, known for its vast prairies and stunning mountain vistas, might not be the first place that springs to mind when you think of solar energy. But with abundant sunshine, especially in the southern regions, solar power is becoming increasingly viable in the province. So, when is the best time of year to harness that Albertan sunshine for maximum solar production? Let’s dive in.

Peak Production: Summer’s Golden Hours

June, July, and August:
- These months are the undisputed champions for solar production in Alberta. With the longest daylight hours and the most intense sunlight, your solar panels will generate the most electricity during this period.
- The long days compensate for the intensity of the sun not being as strong as in more southern climates.
Why Summer Reigns Supreme:
- Increased daylight hours mean more time for your panels to soak up the sun’s energy.
- Clear skies and minimal cloud cover contribute to optimal solar irradiance.

Shouldering Seasons: Spring and Fall’s Sunny Potential

Spring (April, May) and Fall (September, October):
- These seasons offer a decent balance of sunlight and milder temperatures.
- While production won’t be as high as in summer, you’ll still see a significant energy output.
- Spring can also be a good time to install, before the summer rush.
Considerations:
- In spring, melting snow can increase reflected light, potentially boosting production slightly.
- Fall production will gradually decrease as daylight hours shorten.

Winter’s Solar Reality: Sunlight’s Short Supply

November to March:
- Winter in Alberta brings shorter daylight hours, lower sun angles, and potential snow cover, significantly reducing solar production.
- However, solar panels still generate electricity in winter, especially on clear, sunny days.
- Snow can reflect light to the bottom of panels and increase production, but only if the panels are not covered in snow.
Winter Challenges:
- Snow accumulation can block sunlight and reduce energy output.
- Shorter daylight hours limit the time your panels can produce electricity.
- It is very important to make sure that the angle of the panels is sufficient to allow snow to slide off.

Maximizing Your Alberta Solar Potential:

Optimal Tilt Angle:
- Consult with a professional solar installer to determine the optimal tilt angle for your location, taking into account Alberta’s latitude and seasonal variations.
Snow Management:
- Consider installing your panels at a steeper angle to facilitate snow shedding.
- Regularly clearing snow from your panels can also improve winter production.
System Design:
- A well-designed solar system can compensate for seasonal variations and maximize year-round energy production.
Net Metering:
- Alberta’s net metering program allows you to send excess energy back to the grid, which can help offset lower winter production.

The Verdict:

While summer is undoubtedly the peak season for solar production in Alberta, a well-designed and properly maintained solar system can generate significant energy throughout the year. Don’t let Alberta’s winter deter you from harnessing the power of the sun!
