As the quest for efficient renewable energy solutions surges, solar panels continue to be a paramount choice for many Canadians looking to go solar.

In Canada, the market has seen a variety of solar panels, each with its unique offerings. Among them, SunPower’s Maxeon solar panels stand tall as the best overall due to their high efficiency rating of 22.8% and a robust 25-year product warranty, making them a reliable choice for long-term solar energy investments. On the flip side, while not exactly the least, REC Solar panels, although acknowledged for their high power output, don’t match the efficiency rating of SunPower, yet still offer a compelling option for those looking to maximize energy yield from their installations.


This diverse range of solar panels provides a rich spectrum of options for Canadians, catering to different needs and preferences in the transition towards solar energy.

But what is solar panel efficiency?

For this list, we define solar panel efficiency as the ability of a panel to convert sunlight into electricity, expressed as a percentage. Higher efficiency means more electricity is generated per square foot, beneficial in space-constrained areas. Although high-efficiency panels may cost more upfront, they offer greater savings over time due to higher energy production, making them a cost-effective solution in the long run. The advancements in solar technology over the years have led to higher efficiency solar panels. They allow homeowners and businesses to get the most out of their solar installations, especially in areas with limited space or lower solar irradiance. By choosing a high-efficiency solar panel, individuals can maximize the solar energy they harvest and the savings they accrue over time.

With this definition out of the way, lets do the rundown of the most efficient solar panels for the Canadian market as of Q4 2023:


SunPower Corporation

SunPower (Maxeon) has been rated as the best overall by Forbes, thanks to its exceptional efficiency. The Maxeon line of solar panels from SunPower boasts a maximum output efficiency rating of 22.8%, which is quite impressive. Forbes elaborates that these panels come with a temperature coefficient of -0.29% per degree Celsius, ensuring that there is minimal efficiency loss even in high-temperature conditions, making them suitable for the varied Canadian climate.
