Hyundai 440W Bifacial N-Type Mono PV Module

Max System Voltage

Product Overview

The Hyundai HiS-T440NF(BK) is a premium 440-watt N-Type mono bifacial solar panel engineered for high-performance residential, commercial, and utility-scale solar installations. Featuring 108 half-cut cells with 16-busbar (16BB) technology and a sleek all-black (BOB) aesthetic with 30mm black anodized aluminum frame and black backsheet, this module delivers exceptional power output, strong bifacial energy gain, and outstanding long-term reliability. With a 1,500VDC system voltage rating, a 417.5W PTC rating, and a 25/30-year warranty, the HiS-T440NF(BK) is built to produce clean energy dependably for decades.

Key Benefits

Bifacial Energy Gain: Dual-sided power generation captures reflected and diffuse light from the ground or mounting surface via the rear face, delivering meaningful additional energy yield above the rated 440W front-side output — particularly effective on light-colored or reflective surfaces.

Advanced N-Type Cell Technology: N-Type mono-crystalline silicon cells deliver superior conversion efficiency, significantly lower light-induced degradation (LID), and better performance at elevated temperatures compared to conventional P-Type cells — preserving more output over the module's full lifetime.

16-Busbar Half-Cut Design: 108 laser-cut half cells with 16 busbars per cell reduce internal resistive losses, lower the impact of partial shading on string output, and improve overall module efficiency and mechanical durability against micro-cracking.

All-Black Aesthetic (BOB): The black-on-black design — 30mm black anodized aluminum frame paired with a black backsheet — delivers a premium, low-profile appearance that integrates seamlessly into roof-mounted and design-conscious residential installations.

High PTC Rating (417.5W): A PTC rating of 417.5W reflects strong real-world performance under PVUSA Test Conditions, giving system designers and installers confidence that this module will deliver close to its rated output in actual field deployments — not just under ideal laboratory conditions.

25/30-Year Warranty Protection: Backed by a 25-year product warranty and 30-year linear power performance guarantee, the HiS-T440NF(BK) provides dependable, warranted energy production over the full operational life of the solar system.

How It Works

The Hyundai bifacial module captures solar irradiance on both its front and rear surfaces simultaneously. N-Type mono-crystalline cells on the front face convert direct sunlight into electricity at high efficiency, while the transparent rear side absorbs albedo light reflected from rooftops, ground surfaces, or surrounding structures — boosting total energy output beyond what a standard monofacial panel can achieve.

N-Type Mono-Crystalline Cells: High-purity N-Type silicon cells exhibit lower carrier recombination rates than P-Type cells, resulting in higher baseline efficiency, reduced LID over the first years of operation, and better temperature performance — maintaining more output per watt as rooftop temperatures rise.

Half-Cut Cell Architecture: Each full cell is laser-cut in half, halving internal current and reducing I²R resistive losses. The module is split into two independent electrical halves, so shading or soiling on one portion of the panel has a reduced impact on total output compared to a full-cell design.

PV Wire & Junction Box: Equipped with 1,200mm (~47.2") MC4-compatible PV wire leads and a weatherproof junction box with bypass diodes, the module enables safe, fast string wiring and provides hot-spot protection for long-term reliability in the field.

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.

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.
