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.

High efficiency of 20.4%

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.

Improved efficiency at high temperatures

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.

Quality and reliability

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.

Low degradation for increased lifespan

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.

Improved frame design

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.

A1 is great! They are very helpful, knowledgeable and fast. They take pride in their work, and they package the panels for safe delivery.These panels are absolutely great. They actually produce the rated 455W and more on colder days. I am so glad I bought them on A1's recommendation. Thank A1.

Please advise what 1500vdc means. Does this mean you can’t attach more than 3 panels in series?

It's the maximum system voltage that must not be exceeded. You can connect way more than three panels in series.
I want a system independent of power station in case of shortages . I do not have inverter .I do not pay tax do that discount is irrelevant . How much it would cost material and installation in Venice Fl. For one family home? I do not need to cover all but most urgent things during storms.

The average price of an off-grid system is around $30K. Considering that you want your setup to cover only the most urgent things, it could be significantly lower, probably about $10K to $15K. You can give us a call to get the details.
Is this a 144 half cell panel, or a 72 full cell panel?

This panel consists of 144 half-cut cells.
