GCL System Integration GCLSI 725W N-Type Bifacial Monocrystalline Solar Panel

Model GCLSI 725 | N-Type Bifacial Monocrystalline | 132 Half-Cell | Bifacial | 1500V System Voltage

725 Wp

Max Power Output

23.34 %

Module Efficiency

N-Type TOPCon

Product Overview

The GCL System Integration GCLSI 725W N-Type Bifacial Monocrystalline Solar Panel delivers very high output for utility and commercial projects. This advanced N-type bifacial module uses efficient monocrystalline cells to reach up to 23.34 percent panel efficiency. A strong mechanical design and optimized electrical behavior support reliable performance in harsh environments. The bifacial design allows extra power harvest from reflected light on the rear side. With a robust 12 year product warranty and long term power guarantee, this panel supports dependable energy yields over decades.

Key Benefits

Ultra high power density: The 725 Wp rating and efficiency up to 23.34 percent enable more power per string and reduce required roof or ground area for target output.

Advanced N-type bifacial technology: N-type monocrystalline cells limit light induced degradation while the bifacial structure harvests additional rear side energy, improving long term yields.

Excellent temperature behavior: A low temperature coefficient of power at minus 0.29 percent per degree Celsius supports stable output in hot climates and on high irradiance days.

Durable construction and protection: Anti reflection coated glass, anodized aluminium frame and IP68 junction box provide dependable protection against dust, moisture, wind and snow.

Long term performance warranties: A 12 year product warranty combines with a 30 year power warranty which guarantees 99 percent in year one and 87.4 percent output at year thirty.

How It Works

This GCLSI 725W N-type bifacial monocrystalline panel converts sunlight into DC electricity using high efficiency silicon cells. Light strikes the front surface and passes through the anti reflection coated glass to the N-type cells. Additional reflected light reaches the rear side, where the bifacial structure generates extra current. The combined energy is collected through the internal busbars and delivered via MC4 compatible connectors to your inverter or charge controller. The module operates effectively across a wide temperature range and in demanding outdoor conditions.

Front side power generation: Sunlight hits the front glass and is transmitted through the low iron substrate. The anti reflection coating reduces losses from surface reflection and increases photon absorption. Monocrystalline N-type cells convert this energy into electrical current with high efficiency and stability.

Rear side bifacial gain: Reflected and diffuse light from ground or roof surfaces reaches the rear side of the cells. The bifacial architecture converts this additional irradiance into extra power output. Proper array design and bright surfaces under the modules can significantly enhance annual energy production.

System integration and protection: DC current flows through the 4 mm² solar cables to the DC input of the inverter in a grid tied or off grid system. The junction box with three bypass diodes protects against hotspot formation under partial shading. The anodized aluminium frame, IP68 enclosure and robust glass maintain performance over the full 30 year power warranty period.

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.
