Product Overview

The CW Enerji CWT555-108TNB12 solar panel delivers 555 watts of high-efficiency power in a compact bifacial design. This N-type TOPCon monocrystalline module is engineered for demanding residential, commercial, and industrial projects that require strong performance and long-term reliability. With module efficiency up to 21.68 percent, it helps maximize energy yield from limited roof or ground space. The bifacial construction allows energy generation from both the front and rear sides, enhancing output where reflective surfaces are available. A robust double-glass structure and IP68 junction box support long field life, even in harsh environments with dust, salt, or ammonia exposure. Backed by long product and performance warranties, this panel is designed to deliver stable returns over decades of operation.

Key Benefits

High power density for limited space: The 555 Wp output and up to 21.68 percent efficiency allow more energy from each square meter, reducing the number of modules required on constrained roofs or ground arrays.

Bifacial generation for higher yields: Bifacial N-type TOPCon cells can harvest light from the rear side, increasing energy production on reflective surfaces such as light gravel, concrete, or white membrane roofs.

Reliable performance in low light: Outstanding low irradiation performance helps maintain strong output during cloudy mornings, evenings, and hazy conditions, supporting more stable daily energy generation.

Durable construction for harsh climates: The module withstands wind loads up to 2400 Pa and snow loads up to 5400 Pa, while double glass and robust framing support long service life in challenging weather zones.

Long-term value with slow degradation: A low annual degradation rate of around 0.42 percent helps maintain 93.4 percent performance at year twelve and 87.4 percent at year thirty, protecting long-term energy yields.

Positive power tolerance for dependable output: A power tolerance of 0 to +5 W ensures that every shipped module meets or exceeds its rated power, supporting accurate system design and performance expectations.

How It Works

This CW Enerji CWT555-108TNB12 solar panel converts sunlight into usable DC electricity using advanced N-type TOPCon monocrystalline cells. When the front and rear surfaces are exposed to light, photons strike the silicon cells and release electrons, generating electrical current that flows through the module’s busbars. The resulting DC power is routed through the IP68 junction box and cables to an inverter, where it is converted into AC electricity suitable for homes, businesses, or commercial facilities. The bifacial design allows both faces of the panel to participate in energy generation, improving total yield in well-designed systems. Temperature-optimized cell technology and a low temperature coefficient help maintain performance as the module heats up in real-world operation. Over time, a carefully engineered degradation profile and robust encapsulation support consistent output across the full warranty period.

N-Type TOPCon cell technology: N-type TOPCon cells use high-purity silicon and a passivated contact structure to reduce recombination losses and improve efficiency. This design supports strong performance at high irradiance and helps maintain efficiency at elevated temperatures, contributing to greater annual energy production.

Bifacial double-glass construction: The panel uses a bifacial double-glass structure that exposes both the front and rear cell surfaces to incoming light. Direct sunlight is captured on the front side, while reflected and diffuse light from the ground or roof surface is harvested by the rear side, increasing overall system yield when installation conditions are suitable.

Power delivery and system integration: Generated DC electricity flows through 18-busbar cell interconnections to the junction box, which offers IP68 protection for secure outdoor operation. From there, wiring connects the module strings to a compatible string or central inverter, where DC power is converted to AC for on-site consumption or export to the grid as defined by the system design.

Customer Success Stories

Troy P

EG4 off-grid base kit, Happy with my purchase.

This is the first stage of my three planned purches. I got the eg4 inverter 6000 XP base kit with six 400 watt panels and the two server rack batteries. Did a little online research and followed the instructions and it got set up without any issues. Right now I'm just running it in my garage on a single outlet and have been running dual 750 watt water distillers with it. Once I get the second inverter and a bunch more panels and batteries, I plan on attaching it to my subpanel in my house that has my lights and outlets and appliances on it. Then I'll get a soft start for my AC and blower and run it on my main panel.

Easy Process, Genuine Support

Trying to pick the correct solar system for your needs can be very technical and frustrating. I wanted to thank Yvhan and the Portlandia Electric supply team for their patience and helpful attitudes through multiple calls. I feel like we were able to narrow it down to what worked for me and my family. My system works great and I couldn't be happier to have picked Portlandia Electric Supply.

Patrick B

Off Grid Solar Purchase

I wanted to get an offgrid solar system for years but didn’t know where to start. I found Portlandia Electric Supply on Facebook and decided to submit a quote. Within 24 hours I had a custom proposal that was almost half the price of the companies I had previously got quotes from. My wife and I decided to order online and the kit came in a timely manner and it was an easy install. Great company to work with!

James Martin

Highly Recommend

I would like to take the time to express the outstanding service that I was provided with by Portlandia Electric Supply. They provided me with all the answers to my questions, and after reviewing our quote over the phone I felt comfortable proceeding to order my kit. It’s exactly what I needed and they were there to help us over the phone when we had questions installing it. I highly recommend others in need to choose Portlandia Electric Supply.

Best Tech Support

You folks have been wonderful guiding me through the ins and outs of going solar. Plus your tech guys Rod and Nelson are the absolute best. They explained all the different aspects of inverters, batteries and how to keep them in top condition. Too much more to put here… but no other company has the 100% tech support you provide for your customers!
