Introduction
One of the most common questions we hear is:
“What’s the best time of year to install solar panels?”
The truth is, solar panels can be installed in any season. But depending on your goals, the condition of your roof, and the installer’s availability, some seasons offer better advantages than others.
In this post, we break down the pros and cons of installing in spring, summer, fall, and winter to help Alberta homeowners choose the right time for their solar project.
Spring: The Most Popular Time to Go Solar
Why spring is ideal:
You start producing energy just as sun hours increase
You maximize production for the first full year
Installers have more availability compared to peak summer
You’re ready to offset high summer electricity usage
Installing in spring helps you maximize your savings over the next 12 months. It's also a great time for roof inspections and energy evaluations before peak demand hits.
Summer: High Demand but High Output
Why summer works:
Alberta gets the most sun between May and August
Solar panels generate peak output in these months
You can immediately start building net billing credits
Great for households with high AC or EV usage
The challenge? Summer is busy for solar companies, so booking early is important. If you wait too long, you might face longer lead times for equipment and permits.
Fall: The Strategic Saver’s Choice
Why fall is underrated:
Easier scheduling as demand starts to cool
You’ll start producing energy before winter rates increase
Net billing credits from fall can offset winter usage
Cooler temperatures improve panel efficiency
Fall installations help reduce your winter energy costs and let you start fresh in the new year with a full system already running.
Winter: Still Possible, Just Be Prepared
Why winter works with the right team:
Shorter wait times for installation
Possible discounts or off-season incentives
Cooler weather improves panel performance after snow clears
The main challenge with winter installations is weather delays. Snow, wind, and icy roofs can slow down the project timeline. However, experienced installers like LUMI Renewables plan around these conditions and maintain high safety standards.
So, What’s the Best Time for You?
Here’s a quick summary:
Spring is ideal if you want to get a strong return on investment right away. The days are getting longer, solar production increases, and you'll be ready to offset your higher summer energy use. Just keep in mind that spring is a popular season, so installer schedules can fill up quickly.
Summer is the peak season for solar production in Alberta, which means you can start generating maximum energy right after installation. It is perfect for homeowners with high electricity use from air conditioning or electric vehicles. However, because summer is the busiest time for solar companies, lead times may be longer if you wait to book.
Fall is often overlooked, but it can be a smart time to install. The weather is still mild, and demand begins to slow down, which can lead to quicker turnaround times. You'll also start building credits before winter, helping to reduce your cold-season utility bills. Although the days are shorter, solar panels still perform well in Alberta’s crisp, sunny fall weather.
Winter installations are definitely possible and often come with faster scheduling availability. Cold temperatures actually improve panel efficiency once the snow clears. The main trade-off is the potential for weather-related delays due to snow or icy conditions, which can slightly slow down the installation process.
