Product Overview

The GCL System Integration GCLSI 720 720W N-Type Bifacial Monocrystalline Solar Panel is engineered for projects that demand maximum power and long‑term reliability. With an impressive 720 watt peak output and panel efficiency up to 23.18 percent, it delivers strong performance even where roof or ground space is limited. N-type monocrystalline cells and bifacial technology help capture more sunlight from both the front and rear sides. This advanced design supports lower system costs per watt over the lifetime of the array.

Built around 132 high‑efficiency 210×105 millimeter cells, the module operates up to 1500 volt systems and suits utility, commercial, and large residential installations. A robust anodized aluminium frame, 2 millimeter anti‑reflection glass, and IP68 junction box support dependable outdoor use in harsh climates. Optimized temperature coefficients keep energy yields higher in hot conditions. Combined with a 12 year product warranty and long‑term power guarantee, this panel is designed to provide stable output for decades.

Key Benefits

Ultra‑high power density: With 720 watt maximum output, each module delivers more energy per unit area. This helps reduce mounting hardware, cabling, and installation labor for large systems.

High efficiency N‑type cells: Panel efficiency up to 23.18 percent means more kilowatt‑hours from the same footprint. N‑type cell design typically offers lower light‑induced degradation, supporting stable performance.

Bifacial energy gain: Bifacial construction allows the rear side to capture reflected light from surfaces. This can increase real‑world energy yield, especially over bright ground or rooftop coverings.

Stable long‑term performance: Power warranty states 99 percent in year one and 87.4 percent after 30 years. A low total degradation rate of 0.42 percent per year helps protect lifetime returns.

Robust design for tough sites: Operating temperature range from minus 40 to 85 degrees Celsius suits varied climates. Anodized aluminium frame, durable glass, and IP68 junction box provide strong environmental resistance.

Flexible system integration: A 1500 volt maximum system rating supports long strings and fewer combiner boxes. Standard MC4 connectors and 4 square millimeter cables simplify design with modern inverters.

How It Works

Inside each GCLSI 720 module, 132 N‑type monocrystalline cells convert sunlight into direct current electricity. When the front and rear surfaces are illuminated, photons excite electrons in the silicon lattice and create an electric field. This field drives current through the interconnected cell string at a working point defined by the maximum power values. The module’s electrical characteristics, such as 40.84 volt Vmpp and 17.63 amp Impp, are matched to modern inverters. Once connected, the inverter transforms the direct current output into grid‑ready alternating current power.

The panel operates reliably across a broad temperature range, with temperature coefficients that moderate power loss in heat. Anti‑reflection glass improves light capture, while the bifacial structure uses reflected light to boost rear‑side current. The IP68 junction box houses bypass diodes that help protect energy yield under partial shade. When multiple modules are wired in series and parallel, a stable, high‑voltage string is formed. This string feeds the inverter or power station, which then delivers clean power into on‑grid or off‑grid systems.

Front and rear light harvesting: The bifacial design allows light to enter through the front glazing and reach the rear cell surfaces. Reflected radiation from the ground or surrounding surfaces generates additional current on the rear side. This process increases overall energy production compared with standard monofacial modules.

Maximum power operating point: At standard test conditions the panel delivers 720 watt at 40.84 volt and 17.63 amp. Inverters track this operating point continuously using maximum power point tracking algorithms. As irradiance and temperature change, the current and voltage shift, and the tracker adjusts the load. This keeps the system close to the highest possible power output at all times.

Thermal behavior and protection: The temperature coefficient of Pmax is minus 0.29 percent per degree Celsius, limiting losses in hot weather. Coefficient values for Voc and Isc guide system designers when sizing strings for extreme temperatures. Three diodes in the IP68 junction box help mitigate hot‑spot risks under shading or soiling. Standard MC4 connectors maintain reliable contact and simplify safe series or parallel wiring.

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.
