BYD NLBK-36 575W N-Type TOPCon Bifacial Solar Panel

Model NLBK-36 | N-Type TOPCon Bifacial | 144 Half-Cell | Bifacial | 1500V System Voltage

575 Wp

Max Power Output

22.26%

Module Efficiency

144

N-Type TOPCon

Product Overview

The BYD NLBK-36 575W solar panel is built for high-output commercial and residential energy projects. It uses monocrystalline N-Type TOPCon bifacial technology to improve energy harvest and long-term stability. The module delivers a strong 575 Wp output with 22.26% efficiency, supporting efficient system design in limited roof or ground-mounted spaces. Its 144 half-cell layout helps reduce resistive losses and improve performance under real-world conditions. With a 12-year product warranty and a 30-year power warranty, it is designed for dependable operation over decades. The panel also supports a 1500V system, which is ideal for modern utility-scale and commercial arrays.

Key Benefits

High Power Output: The 575 Wp rating supports strong energy production from each module.

Excellent Efficiency: At 22.26%, more sunlight is converted into usable electricity.

Bifacial Energy Gain: Rear-side light capture may increase total system yield in reflective environments.

Long-Term Reliability: N-Type TOPCon cell technology is known for low degradation and stable output.

Modern System Compatibility: The 1500V maximum system voltage suits advanced commercial string designs.

How It Works

This solar panel converts sunlight into direct current electricity through advanced monocrystalline N-Type TOPCon cells. The cells are arranged in a 144 half-cell format, which helps reduce internal power losses and improve current flow. Because the module is bifacial, it can absorb light from both the front and rear sides. That design can improve total energy yield when installed over bright surfaces or open mounting structures. The low temperature coefficients also help preserve performance during hot weather. This makes the module a strong choice for projects that need consistent output and long operating life.

N-Type TOPCon Cell Conversion: Sunlight is converted efficiently into electricity by the monocrystalline cell structure. The N-Type design helps support lower degradation over time.

Half-Cell Electrical Layout: The 144 half-cell configuration reduces resistance and improves shading tolerance. It also supports more stable performance in varied conditions.

Bifacial Light Capture: Rear-side irradiance can be used in addition to front-side sunlight. This can increase total system output when the mounting environment is favorable.

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.
