Great power output with PERC and split cell technology

Canadian Solar panels harvest more energy thanks to PERC technology: engineers have perfected the construction of a cell and added reflective coating. As a result HiKuBlack Mono shows a solid 19.7% conversion rate, higher than average numbers on the market. Split cell technology also increases power output by lowering the resistance.

Panels are ready for tornadoes and hurricanes

HiKu Black is designed to be especially durable: it withstands snow load up to 8100 Pa and wind load up to 6000 Pa. Extreme weather conditions aren’t a threat to this module: hail, tornadoes, hurricanes won’t be able to break it.

Half-cut cell design improves shading tolerance

The panel is split in two independent halves that are connected in parallel. Therefore when a cell in one half gets shaded, it doesn’t affect the other half of a panel at all. Half-cut cell design also contributes to making the panel sturdier and increases its lifespan. The panel is less vulnerable to microcracks and hot spots. 

Comes with 25-year warranties for performance, materials and workmanship

Canadian Solar takes a step forward with HiKu Black: the warranties for this model are much better than with other panels from this brand. The panel comes with 25-year product warranty for materials and workmanship, and 25-year performance warranty. 1st year power degradation doesn’t exceed 2% and subsequent annual power degradation is no more than 0.55%.

As someone who lives in florida i just needed panels that would be able to endure all the different kinds of weather that comes here. i bought these. so far they are just perfect. i love the design, i love the look, i like how clouds barely affect them. when the hurricane comes, i’ll be ready

hi, how do these panels do when it’s gloomy outside?

the performance of panels usually drops by 40-10%. Canadian Solar deals well with bad weather, so the percentage is going to be low with their panels.
what’s the minimum order size?

No less than 6 panels at the moment
