About product
CS3W-385PB-AG is a model that uses a number of technologies to bring durability and performance to the next level. CS3W-385PB-AG uses polycrystalline solar cells. These are often slightly less efficient than monocrystalline options, but substantially more affordable, meaning a shorter payback period. What’s more, Canadian Solar’s expertise and technologies allow them to nearly close the gap in efficiency, while leaving the gap in price untouched. 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-385PB-AG two times smaller than the standard size, thus reducing power loss and improving low-light behavior. At 17.23% efficiency, CS3W-385PB-AG offers surprising performance for its weight and size. 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 a 10-year product warranty. Stable power output is also guaranteed — performance warranty will protect you during 30 years.
More power and efficiency
An already high efficiency of 17.23% is further enhanced by polycrystalline technology. By adding a solid PID resistance and special glass lamination on top, the manufacturer ended up with an efficient and very durable model. Under standard test conditions, CS3W-385PB-AG outputs 385 W of power.
CS3W-385PB-AG manages to stay efficient even at high temperatures. For every 1.8°F above 77°F, it loses just 0.37% in efficiency, allowing you to make the most of the sunniest hours.
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 2.5% during the first year and then will be limited to 0.60% annually. Your modules will retain at least 80.1% of original performance after the 30 years are over. This 385 W Canadian Solar solar panel also comes with a generous 10-year product warranty.
The 1.2" frame made from anodized aluminum and a layer of protective tempered glass make this module resistant to the foulest of weather. The front side of the modules can resist a 5400 Pa load, and the back side 2400 Pa.
