BYD NLBK-36 595W N-Type TOPCon Bifacial Solar Panel

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

595 Wp

Max Power Output

23.03%

Module Efficiency

144

N-Type TOPCon

Product Overview

The BYD NLBK-36 595W solar panel is built for high output, strong reliability, and long service life. Its N-type TOPCon bifacial design helps capture more energy than standard modules. That makes it a strong fit for commercial rooftops, industrial sites, and utility-focused projects. With 595 watts of rated power and 23.03% efficiency, the module is designed to maximize energy generation in limited space. The 144 half-cell layout supports stable performance and improved current handling. A 12-year product warranty and 30-year power warranty provide added peace of mind for long-term investment planning.

Key Benefits

High power density: Delivers 595 Wp output for stronger production per module.

Excellent efficiency: Reaches 23.03% efficiency for better space utilization.

Bifacial energy gain: Rear-side generation can improve total yield in suitable installations.

N-type TOPCon technology: Supports lower degradation and strong long-term performance.

Project-ready durability: Built with anodized aluminum framing, IP68 junction protection, and 1500V system support.

How It Works

This module converts sunlight into electricity through high-efficiency N-type solar cells. The 144 half-cell structure helps reduce resistive losses and supports steadier output across the panel. Its bifacial design can also harvest reflected light from behind the module. That means more total energy may be produced when the installation surface and mounting setup allow rear-side exposure. TOPCon cell technology is used to improve carrier collection and help limit performance loss over time. The panel is engineered for stable operation across demanding environmental conditions. Its electrical design supports high-voltage systems and consistent string integration in larger arrays.

Sunlight conversion: The monocrystalline cells absorb solar energy and convert it into usable DC power. The high efficiency helps more energy be captured from the available surface area.

Bifacial generation: Light can be collected from both the front and rear sides of the module. This can increase total output in reflective environments.

System integration: The panel operates with a 1500V maximum system voltage. It is suited to multi-panel string layouts in commercial and utility installations.

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.
