About product
455MB-AGP is part of the BiHiKu Series — one of the most recent made by Canadian Solar. These panels employ cutting-edge technologies to achieve superior efficiency and reliability. The Passivated Emitter Rear Contact (PERC) technology ensures excellent power output. This solar cell type employs an additional reflective layer to absorb more sunlight.
Half-cut cell technology adds a few more percent to the overall performance, making this model a great example of efficiency. Canadian Solar made solar cells in CS3W-455MB-AGP two times smaller than the standard size, thus reducing power loss and improving low-light behavior. The efficiency of this model reaches 20.4% — well above the market’s average. And while conventional panels use only one side to absorb photons, bifacial modules employ both sides at the same time. Thanks to the technology, this model can be up to 30% more efficient. Canadian Solar offers 12 years of product warranty and guarantees 84.95% of original performance after 30 years of operation.
Canadian Solar Canadian Solar panels have a high efficiency of 20.4 percent and take full advantage of the company's technologies, which have won Canadian Solar several honors. This PERC option produces more electricity per square foot of PV modules. This translates to shorter installation times and fewer clamps and racks. All of this lowers your overall expenditures and shortens the payback period.
Greater energy as temperature rises is a mark of a good temperature coefficient. Your panel's efficiency will drop by just 0.34% for every 1.8°F increase over 77°F.
CS3W-455MB-AGP undergoes various quality checks during the production process and is subjected to serious quality and reliability testing. Manufacturing facilities are highly automated, removing the possibility of human errors. Canadian Solar is committed to quality, safety, and dependability to ensure you get the finest.
The amount of power output loss experienced by these panels during the first year of operation will not exceed 2%. The average yearly power drop from the second to the 30th year will not surpass 0.45%. After 30 years, the module will still produce more than 84.95% of its initial output.
CS3W-455MB-AGP design makes it suitable for both residential and business rooftops. The use of a strong 1.2" frame composed of anodized aluminum boosts durability and strength. The model can withstand a significant snow load of up to 5400 Pa. The panel's back can withstand 3600 Pa, guaranteeing that your system will resist even the fiercest winds.
