Product Overview

The BYD NLBK-36 is a high-performance bifacial solar panel engineered for maximum energy yield across residential, commercial, and utility-scale installations. Delivering a power output range of 555–580W with a module efficiency of up to 21.5%, it leverages advanced N-type TOPCon cell technology across 144 cells to achieve superior conversion efficiency, lower degradation rates, and outstanding performance in real-world conditions. With up to 80% bifaciality, an IP68-rated junction box, 25-year warranty, and a robust frame rated for 5400 Pa snow loads and 2400 Pa wind loads, the NLBK-36 is built to deliver reliable, high-yield energy generation for decades — while meeting the highest international safety and environmental standards.

Key Benefits

Industry-Leading Power Output: Delivering up to 580W per panel with a module efficiency of 21.5%, the NLBK-36 maximizes energy production per square meter — reducing the total number of panels needed and lowering overall system cost.

Advanced N-Type TOPCon Technology: N-type TOPCon cells offer inherently lower light-induced degradation (LID), improved performance at high temperatures, and a superior temperature coefficient of -0.30%/°C compared to conventional P-type PERC modules.

Enhanced Bifacial Energy Gain: With up to 80% bifaciality, the rear side captures reflected and diffuse irradiance from ground surfaces, delivering up to 30% additional energy yield in suitable installation environments such as ground mounts and flat rooftops.

Structural Durability for Harsh Climates: Engineered to withstand snow loads up to 5400 Pa and wind loads up to 2400 Pa, the NLBK-36 is designed for reliable long-term deployment across demanding environmental conditions worldwide.

Sustainable, Lead-Free Manufacturing: Produced with recyclable, lead-free materials and backed by a 25-year warranty, the NLBK-36 delivers both environmental responsibility and long-term investment confidence.

How It Works

The BYD NLBK-36 harnesses sunlight through its 144 N-type TOPCon cells on the front surface while simultaneously capturing reflected irradiance through the rear side. Its advanced cell architecture, optimized junction box, and favorable temperature characteristics work together to ensure consistent, high-efficiency power generation throughout the day and across all seasons.

N-Type TOPCon Cell Architecture: Tunnel Oxide Passivated Contact (TOPCon) technology minimizes surface recombination losses in N-type silicon, achieving higher conversion efficiency and slower long-term degradation than conventional P-type PERC cells.

Bifacial Energy Generation: The transparent rear side absorbs light reflected from the ground or mounting surface, boosting total energy output by up to 30% in appropriate deployment environments — without any additional hardware.

IP68 Smart Junction Box: The IP68-rated junction box provides complete protection against dust ingress and sustained water immersion, ensuring long-term electrical reliability and safety across all installation environments.

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.

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.
