Product Overview

The CW Enerji CWT655-132PMB12 bifacial PERC monocrystalline solar panel delivers high efficiency and dependable performance for utility, commercial, and large roof projects. With a maximum power output of 655 Wp and module efficiency up to 21.09%, this module helps reduce balance of system costs while maximizing energy yield per square meter. The advanced bifacial design allows energy capture from both the front and rear sides, increasing total power generation on reflective surfaces such as white roofs, concrete, or light gravel. A robust aluminum frame, IP68 junction box, and certified resistance to wind and snow loads support durable operation in challenging climates. This 132-cell module is engineered for 1500 V systems, enabling longer strings and lower BOS costs. Designed and manufactured in Turkey by CW Enerji Mühendislik Ticaret ve Sanayi A.Ş, it combines high conversion efficiency, self‑cleaning glass, and long-term performance warranties, making it a strong choice for bankable solar installations where output, reliability, and lifetime value matter.

Key Benefits

High power density for large-scale projects: A 655 Wp output and 21.09% efficiency allow more installed capacity on the same footprint, which helps optimize limited roof or ground space and can reduce overall project cost per watt.

Bifacial energy gain: Rear-side generation captures reflected light from bright surfaces, increasing total kWh production over the system lifetime and improving project returns without extra module area.

Reliable long-term performance: A linear performance warranty with 90% power at 12 years and 83.5% at 30 years supports predictable energy yield projections and enhances investor confidence in long-term cash flows.

Enhanced durability and weather resistance: The IP68 junction box, anti‑reflection glass, and certified wind and snow load ratings are designed to withstand harsh outdoor conditions and reduce maintenance interventions over time.

Optimized for modern 1500 V systems: Compatibility with 1500 V system voltage and a 30 A series fuse rating enables flexible string design, improved efficiency of inverters, and lower cabling and installation costs on larger arrays.

How It Works

This high-efficiency solar panel converts sunlight into usable DC electricity through its 132 monocrystalline PERC cells arranged in a 6×22 layout. Incoming light hits the textured cell surface and anti‑reflection glass, where it is absorbed and converted into electrical energy through the photovoltaic effect. Because this module is bifacial, light striking the rear side is also harvested, which boosts overall energy yield, especially when mounted over reflective surfaces or on elevated racking. The panel operates within a wide temperature range from -40°C to +85°C, and its carefully engineered temperature coefficients help maintain stable output under real‑world conditions. When connected in strings to a compatible inverter, the generated DC power is converted into AC electricity that can be used on site or exported to the grid. The linear performance warranty and low annual degradation rate support a consistent energy profile over decades, allowing system designers to model long-term production with confidence.

PERC monocrystalline cell architecture: Passivated emitter and rear cell technology increases light capture and reduces electron recombination losses, which improves conversion efficiency compared to standard cells. The monocrystalline silicon structure supports higher performance and delivers a strong power temperature profile in varying climates.

Bifacial energy harvesting: The module is designed to absorb light from both front and rear sides, using the rear glass and cell layout to pick up diffuse and reflected radiation. This design can increase real-world output beyond the nameplate rating when installed over bright surfaces or on elevated mounting systems.

Self-cleaning, anti-reflection glass and robust construction: The coated glass helps minimize dust accumulation and reflection losses, which sustains strong performance between cleaning cycles. Combined with the IP68 junction box, sturdy frame, and high mechanical load ratings, the panel is engineered to operate safely in demanding environments for many years.

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

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!
