Product Overview

The GCL System Integration GCLSI 730 N-Type Bifacial Monocrystalline Solar Panel delivers very high output in a large format module. This advanced panel uses N-type bifacial cell technology to capture sunlight from both the front and rear sides. With up to 730 Wp of maximum power and module efficiency up to 23.5%, it suits utility scale plants and large commercial roofs. The monocrystalline half cells are arranged in a 132 cell layout with 210×105 mm wafers for excellent current handling. A robust anodized aluminium frame and 2 mm anti-reflection glass protect the module in harsh environments. The panel operates reliably from -40°C to 85°C and supports 1500 V system designs for modern string inverters. Low temperature coefficients and a low degradation rate of 0.42% per year help maintain strong lifetime yields. This GCLSI 730 panel is designed to provide bankable performance, efficient space usage, and long term energy security.

Key Benefits

Ultra high power density: Each module supplies up to 730 watts, reducing the number of panels needed per project and lowering mounting hardware costs.

Bifacial energy gain: N-type bifacial cells harvest extra light reflected from the ground or roof, generating higher kWh per installed kilowatt.

Excellent efficiency and footprint: Module efficiencies up to 23.5% optimise available space, which is ideal for constrained commercial roofs or high value land.

Reliable thermal performance: Low Pmax temperature coefficient of -0.29% per degree Celsius supports better performance in hot climates and summer peaks.

Durable construction: The 2 mm anti reflection glass, IP68 junction box, and anodized aluminium frame provide long term protection against dust and moisture.

Bankable warranties: A 12 year product warranty and long term power warranty with 87.4% output at year 30 support project bankability.

How It Works

This GCLSI 730 solar panel converts sunlight into usable electricity using high efficiency N-type monocrystalline cells. When sunlight hits the front surface, photons are absorbed and generate charge carriers in the silicon lattice. The internal electric field of each solar cell drives these charges in one direction, creating direct current. Because the panel is bifacial, the rear side also captures reflected and diffused light from the environment. This additional irradiation typically increases total energy yield when modules are mounted above bright or reflective surfaces. The 132 half cell layout keeps resistive losses low and allows high currents to flow with excellent reliability. Factory installed MC4 connectors and 4 mm² cables then deliver the generated power to string inverters or charge controllers. The module operates best when mounted at an angle that optimizes both front and rear side exposure to available light.

N-Type bifacial cell operation: The N-type cells are engineered with low light induced degradation, which helps preserve output over many years. Both faces of the cell are active, so light from the sky, ground, and nearby surfaces is converted into current.

DC power delivery: At standard test conditions, the module operates at around 41.22 volts and 17.71 amps at maximum power. This direct current is combined in series and parallel strings to match inverter input windows on utility or commercial systems.

Thermal and environmental control: The low temperature coefficients reduce power loss as cell temperatures rise during strong sun. Robust sealing, an IP68 junction box, and anodized frame keep moisture and dust away from sensitive electrical parts.

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.
