Product Overview

The CW Enerji CWT660-132PMB12 660W bifacial PERC monocrystalline solar panel delivers very high power density for large scale and commercial systems. This advanced bifacial module uses high efficiency monocrystalline PERC cells and captures light on both sides to increase total energy yield. With a front rated output of 660 Wp and module efficiency of 21.25%, this solar panel helps reduce balance of system costs per installed watt. Its robust glass and frame design allows dependable operation in harsh climates and demanding rooftop or ground mount projects. A wide operating temperature range from -40°C to 85°C supports stable energy production in hot and cold regions. Engineers and installers can rely on the linear performance warranty that limits degradation to 0.55% per year. By year 12 at least 90% of nominal power is retained, and after 30 years at least 83.5% of output remains. This long term performance makes the CWT660-132PMB12 a strong choice for asset owners focused on predictable returns. The panel is designed for 1500 V systems and offers a 30 A series fuse rating for flexible array design. Anti reflection, self cleaning glass and excellent low irradiation response help deliver more energy, even during cloudy conditions or early and late hours of the day.

Key Benefits

High bifacial power output: Front side power of 660 Wp and bifacial gain enable higher energy yield per module. This allows fewer panels for a given system size and can reduce mounting and cabling costs.

Excellent long term performance: The linear performance warranty limits annual power loss to 0.55%. After 30 years at least 83.5% of the rated power remains, which supports reliable project cash flow.

Durable design for harsh conditions: The panel is tested for wind load up to 2400 Pa and snow load up to 5400 Pa. These ratings support installation in exposed sites with strong winds or heavy snowfall.

Enhanced energy capture in low light: Outstanding low irradiation performance supports higher production in cloudy weather and at low sun angles. Bifacial operation also uses ground reflected light to further raise energy yield.

Reliable quality and bankability: The module is manufactured by CW Enerji in Turkey under ISO 9001, ISO 14001 and ISO 45001 systems. It is certified to IEC 61215 and IEC 61730 for safety and performance across its lifetime.

How It Works

This CW Enerji CWT660-132PMB12 solar panel converts sunlight into usable DC power using high efficiency bifacial monocrystalline PERC cells. When sunlight hits the front glass, photons are absorbed in the silicon cells and create an electric current. The bifacial design also collects light on the rear side, so energy from ground reflections and diffuse light is converted. A network of busbars and cell interconnections carries this current to the module junction box. From the junction box, DC power flows through cables to a compatible inverter, which changes it into AC power for buildings or grids. The anti reflection coated glass increases light transmittance and helps reduce soiling, which keeps more energy flowing over time. Temperature coefficients are optimized, so power loss is limited as the module warms under strong sun. Over decades of operation, carefully controlled degradation supports stable annual production for long term projects.

Bifacial monocrystalline PERC cell operation: Each of the 132 monocrystalline PERC cells is engineered to absorb more light and convert it into electricity with high efficiency. The rear side also remains active, so light reflected from bright surfaces or nearby structures contributes to extra power.

Power generation and electrical output: At standard test conditions, the panel delivers 660 Wp at a maximum power voltage of 37.9 V and current of 17.42 A. The open circuit voltage reaches 45.6 V, while short circuit current is 18.44 A, enabling flexible string designs in 1500 V systems.

System integration and protection: A robust IP68 junction box protects electrical connections against dust and water ingress. The recommended 30 A series fuse rating supports safe operation in properly designed arrays, while compatibility with modern inverters allows integration into commercial and utility installations.

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!
