About product

Description

REC Black 355 is a PV module fit for both residential and commercial applications. REC engineers made the TwinPeak series durable and efficient while minimizing the amount of useful space required for their operation. This panel takes full advantage of the Passivated Emitter Rear Contact (PERC) technology that allows it to capture up to 12% more energy. All thanks to a reflective layer on the back. This design maximizes the number of photons absorbed by solar cells. 

Another advantage is the half-cut cell technology. Black 355 has solar cells half the size of those installed in conventional panels. The main benefits are decreased power loss, improved longevity and better low-light performance. Given its size and weight, Black 355 efficiency of 19.4% is quite impressive. REC offers 25 years of product warranty and guarantees 84.8% of original performance after 25 years of operation. 

  • 120 half-cut PERC cells
  • 355 W nameplate capacity
  • 19.4% efficiency
  • 1000 V DC maximum system voltage
  • MC4 connectors
  • 25 years of product and 25 years of performance warranty

High efficiency of 19.4%

REC TwinPeak panels take full advantage of the company’s technologies that have won REC multiple awards. This PERC option offers higher power output per square foot of PV modules. This means quicker installation times and fewer clamps and racks. All of which reduces your overall costs, shortening the payback time.

Exceptional performance in scorching weather

At high working temperatures, a low temperature coefficient equals increased energy generation. Every 1.8°F over 77°F results in a model's efficiency loss of just 0.34 percent.

High quality standards

Multiple tests are part of the REC tight production requirements, which offer the highest level of quality assurance. Because of the facilities' high degree of automation, the business is able to uphold strict standards and minimize the number of warranty claims to an absolute minimum.

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 25th year will not surpass 0.55%. After 25 years, the module will still produce more than 84.8% of its initial output.

Certified for the most challenging environmental conditions

Black 355 is resistant to PID, salt, acid and ammonia. It can also withstand up to 7000 Pa mechanical load on the front and 4000 Pa on the back. Such robustness is mainly due to the 1.18" thick anodized aluminum frame and a layer of protective glass.

Before choosing a brand of panels, we did some reading and talked to our installer. Since Tesla is the first brand that springs to mind, that's the one we were leaning toward. Unfortunately, we had second thoughts after reading some bad Tesla customer service ratings. It was explained to us that REC were just as nice, if not better looking, and came with the same warranty as the more expensive brand. We don't regret this decision

I want a Rec solar panel of 355W but in polycrystalline

At the moment we do not have any 355 W polycrystalline REC panels
So I am interested in buying six 355 watt panels to start my project which I will add to over the next several years. My question is where do I get the cables to connect everything? The splitters to connect the panels in series and then at the end of the line of panels the main home run connecting to the inverter which might be 20 to 30 feet away. oh how long are the cables attached to the panel itself?Thanks

This panel has 3.6 + 3.9 ft cables with MC4 connectors. Wi sell some addons, but at the moment cables are underrepresented. You can buy them elsewhere or choose one of our turnkey solutions by clicking on "Systems" at the very top of this page.
My question is about the number of cells. taking a REC 120 cell versus a mission 60 cell panel with some shading on them which will produce the most energy? this is hard to explain in writing. does having less cells shut off a bigger percentage of the panel if it has partial shading?im on a sailboat and i worry about the mast casting a partial shadow at different times of the day.thanks

Since solar cells are interconnected, the higher number of cells may give no advantage in terms of shading resistance. The number of bypass diodes seems a more relevant metric. For comparison, this model comes with 3 bypass diodes.
