About product
CS6W-550MB-AG is part of the Bifacial 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.
The use of half-cut cell technology is an additional perk. The solar cells of CS6W-550MB-AG are half the size of those found in standard panels. Major advantages include reduced power consumption, extended life and enhanced efficiency in low-light conditions. Given its size and weight, CS6W-550MB-AG efficiency of 21.4% is quite impressive. 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 provides an industry-leading 30-year performance warranty and a 12-year product warranty.
High efficiency of 21.4 percent
Canadian Solar Bifacial panels fully use the firm's innovations, which Canadian Solar has received several distinctions for. With PERC technology, more electricity can be produced per square foot of PV modules. As a result, there will be less clamps and racks required during installation. All of which lowers your overall expenses and accelerates the payback period.
This module makes the heat less dangerous since it has one of the lowest temperature coefficients in the market, losing just -0.34% of efficiency for every 1.8°F over 77°F.
Canadian Solar strict manufacturing standards include multiple tests to provide extreme quality assurance. The facilities are highly automated, allowing the company to maintain high standards and keep the level of warranty claims very low.
Slow degradation over the next 30 years is guaranteed by Canadian Solar. The performance will decrease no more than 2% during the first year and 0.25% annually thereafter. Your modules will retain at least 84.95% of original performance after the 30 years are over. This 550 W Canadian Solar solar panel also comes with a generous 12-year product warranty.
CS6W-550MB-AG is resistant to PID, salt, acid and ammonia. It can also withstand up to 6000 Pa mechanical load on the front and 3600 Pa on the back. Such robustness is mainly due to the 1.18" thick anodized aluminum alloy frame and a layer of protective glass.
