Product Overview

Harness the power of HD Hyundai's premium TOPCon technology with the HiS-T640NJ, a high-output bifacial module engineered for commercial and utility-scale applications. This 640W panel features 156 half-cut N-type monocrystalline TOPCon cells with 16-busbar design, delivering an exceptional 22.90% module efficiency and 80% bifaciality factor for significant rear-side energy gains. The glass-glass construction with clear anodized aluminum frame and semi-tempered solar glass on both front and rear surfaces ensures outstanding durability and long-term reliability. With a verified 605.6W PTC rating demonstrating real-world performance, this panel is purpose-built for large-scale ground-mount and commercial rooftop installations. Rated for 1500V DC systems and backed by a 12-year product warranty and 30-year linear performance guarantee.

Key Benefits

N-Type TOPCon Cell Technology: Advanced Tunnel Oxide Passivated Contact (TOPCon) cells deliver industry-leading 22.90% module efficiency with lower degradation rates, superior low-light performance, and excellent temperature coefficients compared to conventional PERC technology.

High Bifaciality (80%): Dual-glass bifacial design with 80% bifaciality factor captures reflected and diffused light from rear surfaces, boosting total energy generation by up to 25% in optimal ground-mount installations with high-albedo surfaces.

Glass-Glass Durability: 2.0mm semi-tempered solar glass on both front and rear surfaces provides superior mechanical strength, enhanced PID resistance, and long-term protection against environmental degradation for a 30+ year service life.

PTC Rated Performance: 605.6W PTC rating demonstrates real-world efficiency under actual operating conditions, providing reliable performance expectations for system designers and EPC contractors.

Ultra-High Power Density: 640W output from 156 half-cut cells with 16-busbar design maximizes power per unit area, reducing installation footprint, racking, and balance of system costs for large-scale projects.

Genuine Stäubli MC4 Connectors: Factory-fitted genuine Stäubli MC4 connectors ensure reliable, low-resistance electrical connections and full compatibility with industry-standard wiring systems.

How It Works

This solar panel harnesses sunlight through its advanced N-type TOPCon monocrystalline silicon cells, utilizing tunnel oxide passivation to transform solar energy into electricity with exceptional efficiency. The bifacial glass-glass design captures both direct sunlight and reflected light from surrounding surfaces for maximum energy generation.

TOPCon Cell Architecture: Tunnel Oxide Passivated Contact technology creates an ultra-thin oxide layer on the cell rear, dramatically reducing recombination losses and enabling higher open-circuit voltages for superior energy conversion efficiency.

Half-Cut Cell Design: 156 half-cut cells arranged in a 6×26 configuration reduce internal resistance and power loss, improving shading tolerance and delivering higher energy yields in real-world conditions.

Bifacial Glass-Glass Construction: Semi-tempered solar glass on both front and rear surfaces enables rear-side energy capture from reflected and diffused light while providing exceptional mechanical protection and long-term durability.

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.
