Product Overview

The CW Enerji CWT670-132PMB12 670W PERC monocrystalline bifacial solar panel is engineered for utility scale and large commercial projects that demand maximum energy yield from every square meter. Its high module efficiency of 21.57 percent helps systems deliver more power using less roof or ground space. The module uses advanced bifacial PERC monocrystalline cells, which harvest sunlight from both the front and rear sides when installed above reflective surfaces. This design supports a higher energy output per panel compared to conventional monofacial modules. The panel operates reliably across a broad temperature range from minus 40 to plus 85 degrees Celsius. A robust design with IP68 junction box protection supports long term durability in harsh outdoor environments. This module is part of the CW Enerji 132PMB12 series, offering a power class range between 650 and 675 watts for flexible system design. It is an excellent option for developers, EPCs and installers seeking bankable performance with long term warranties.

Key Benefits

High power density for large projects: With a rated output of 670 watts, this module enables powerful arrays using fewer panels and mounting structures, helping reduce balance of system costs on commercial and utility installations.

Bifacial energy gain: Bifacial PERC cell technology captures incident light on both faces of the panel, increasing annual energy yield when installed over bright or reflective surfaces such as white roofs, concrete or light gravel.

Class leading efficiency: Module efficiency up to 21.57 percent allows more kilowatts to be installed in constrained spaces, improving project economics where usable area is limited or premium.

Durable mechanical design: The panel is tested for wind loads up to 2400 pascals and snow loads up to 5400 pascals, while the IP68 junction box and quality encapsulation materials support long field lifetimes in demanding climates.

Long term performance warranty: A 12 year product warranty is paired with a 30 year linear power warranty that guarantees 90 percent output at year 12 and 83.5 percent at year 30, ensuring predictable long term energy production.

Excellent low light performance: Optimized glass and cell design support reliable energy generation in weak light conditions such as mornings, evenings and cloudy days, helping to smooth daily production profiles.

How It Works

This CW Enerji PERC monocrystalline bifacial solar panel converts sunlight into usable direct current power through high efficiency silicon cells. Each of the 132 half cut cells is designed to minimize electrical losses and deliver powerful output under standard test conditions. Light striking the front glass is absorbed by the monocrystalline wafers and converted into electrical energy. At the same time, light reflected from the ground or nearby surfaces reaches the rear side, where the bifacial structure generates additional current. The panel operates as part of a string or array, connected to an inverter that converts direct current to grid compatible alternating current. Careful temperature management, robust materials and precise manufacturing help maintain stable performance during decades of outdoor exposure. When integrated into a well designed mounting system with adequate ventilation and fire resistant backing, the module forms a reliable building block for modern solar power plants.

Bifacial PERC cell operation: Passivated emitter and rear contact technology reduces recombination losses inside the silicon cell, improving conversion efficiency and boosting energy output from each photon absorbed.

Half cut cell and multi busbar layout: The 132 cell configuration uses smaller half cut cells with multiple busbars to shorten current paths, which helps reduce resistive losses and improves shade tolerance compared to full size cell layouts.

Thermal behavior and power stability: The low temperature coefficient of power, at minus 0.34 percent per degree Celsius, limits output losses on hot days and supports consistent performance in warm climates with high irradiance.

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.

Jacob B

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.

Brian H

Solar Kit for Mobile Work Van

As a professional videographer, I needed reliable power on the go.Portlandia Electric Supply Delta Pro and roof-mounted panels were the perfect solution. Setup was easy, and the kit included everything needed. The Delta Pro powers my cameras, lights, laptop, and a small fridge with impressive battery capacity.

Keith S

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!

Coll A

Great Experience

My experience with Portlandia Electric Supply has been excellent. Before the sales, they answered all my questions to assure that I got what I needed. After the sales they continued to support me with answers and help. I had a warranty issue with a unit, and it was handled as well as possible. I would recommend them to anyone looking to go solar.
