Product Overview

The CW Enerji CWT665-132PMB12 665W bifacial PERC monocrystalline solar panel delivers very high output for large ground mount and commercial rooftop systems. This premium module combines bifacial power generation, advanced PERC cell design and durable construction for long term energy production. Its panel efficiency of 21.41% helps maximize capacity where roof or land area is limited. The module uses 210×105 mm monocrystalline cells arranged in a 132 cell layout to deliver stable performance under real world conditions. A robust frame, IP68 junction box and tempered glass support reliable operation from -40°C to +85°C. The CW Enerji CWT665-132PMB12 solar panel is engineered to meet modern project needs, with a 1500V system voltage rating and a 30 year performance warranty. This combination of high power, efficiency and proven durability makes it a strong choice for utility, commercial and industrial installations.

Key Benefits

High power density for large projects: With 665 Wp output and 21.41% efficiency, each module delivers more power per unit area. This allows system designers to reduce string counts and balance of system costs on utility and commercial arrays.

Bifacial gain for improved yield: Bifacial PERC technology captures light on both module sides to increase annual energy production. This is especially beneficial on reflective surfaces such as light gravel, concrete or snow covered ground.

Reliable performance in harsh climates: The panel operates from -40°C to +85°C with low temperature coefficients for power, voltage and current. Wind load up to 2400 Pa and snow load up to 5400 Pa support challenging site conditions.

Self cleaning, anti reflection glass: Anti reflection coated glass enhances light transmission and reduces surface dust buildup. This feature helps maintain stable energy yield and can reduce cleaning frequency on accessible arrays.

Long term value and linear warranty: A 12 year product warranty is combined with a 30 year performance warranty. Power output is guaranteed at 90% after 12 years and 83.5% after 30 years, supported by a low annual degradation rate of 0.55%.

How It Works

This CW Enerji bifacial PERC monocrystalline solar panel converts sunlight into usable DC power using high efficiency 210×105 mm cells. Light striking the front glass is absorbed by the monocrystalline cells and converted into electrical energy. Thanks to bifacial design, reflected light reaching the rear side also contributes to the module output. The generated current flows through 12 busbar cell interconnections and is collected in the IP68 rated junction box. From there, DC power is routed through PV cabling to inverters that convert it to AC electricity. The panel is designed for 1500V systems, so longer strings can be used to improve system efficiency and reduce cable runs. Low temperature coefficients and optimized cell layout help maintain stable performance across a wide temperature range.

Bifacial PERC cell conversion: PERC cells feature a passivated rear surface that improves light capture and internal reflection. The bifacial structure allows both sides of the module to generate current when exposed to sunlight or reflected light.

High efficiency module architecture: Large 210×105 mm monocrystalline cells are arranged in a 132 cell configuration for higher power output. Short current paths, 12 busbar design and optimized interconnections minimize resistive losses within the module.

System integration and protection: The module connects into strings up to 1500V DC, matched to modern central or string inverters. An IP68 junction box, quality encapsulation and durable frame help protect components from moisture, dust and mechanical stress.

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.
