FAQ
Do solar panels work in the winter?
Yes, solar panels still produce electricity during the winter months. While snowfall can temporarily block sunlight, panels are designed at an angle to help snow slide off. In fact, solar panels often perform more efficiently in colder temperatures.
What happens when it’s cloudy or raining?
Solar panels still generate electricity on cloudy or rainy days, just at a reduced level. On average, solar systems in Alberta still perform well year-round due to our high number of sunny days.
How do solar panels hold up against hail?
Most solar panels are built to withstand hailstorms and are tested to endure hail up to 1 inch in diameter at speeds of 80 km/h. We use panels that are certified and designed to meet or exceed Canadian weather conditions.
Will snow damage or block my panels?
Heavy snow may cover your panels temporarily, but it's usually not necessary to clear them off manually. The panels absorb heat and are installed at an angle, so the snow tends to melt and slide off on its own.
Can my system produce enough power during Alberta’s short winter days?
While days are shorter in winter, your system is designed to overproduce during the sunnier months to offset lower production in the winter. Your annual production is what matters most, and Alberta’s long summer days provide excellent energy generation.
Do I need a battery for cloudy days or storms?
Batteries are optional. If you're connected to the grid, your home will still have power even when solar production is low. A battery is useful for backup power or for storing excess energy if you want more independence.
Are solar panels damaged by freezing temperatures?
No. Solar panels are made to function in extremely cold weather. In fact, solar cells work more efficiently in cooler temperatures than in extreme heat.
What happens at night?
Solar panels do not generate electricity at night. However, during the day, they produce more energy than needed, and the excess can be stored in batteries or fed back into the grid. This stored energy can then be used during nighttime or cloudy days.
