BYD NLBK-36 570 N-Type TOPCon Bifacial Monocrystalline Solar Panel

N-Type TOPCon

Product Overview

The BYD NLBK-36 570 N-Type TOPCon bifacial monocrystalline solar panel is designed for high power commercial and utility scale projects. This advanced module delivers up to 570 watts of front side output with outstanding efficiency of 22.07 percent at standard test conditions. N-type TOPCon cell technology is used to reduce light induced degradation and secure long term energy yield. The bifacial construction harvests additional energy from reflected light behind the array. A robust anodized aluminium frame and 2 millimetre tempered glass provide mechanical strength while keeping weight at 32 kilograms. The panel operates within a wide temperature range from minus 40 to 85 degrees Celsius. A 12 year product warranty and 30 year performance warranty support dependable operation in demanding environments. This module suits ground mount, rooftop or tracker installations requiring reliable high power density from a trusted global manufacturer.

Key Benefits

High power density for large projects: Each BYD NLBK-36 570 module delivers up to 570 watts from a compact footprint. This high output reduces the total number of panels needed on commercial rooftops and ground mount systems.

Advanced N-type TOPCon reliability: N-type TOPCon cells have lower degradation and excellent passivated contacts. This design helps maintain strong energy production over the 30 year power warranty period.

Bifacial gain for higher energy yield: The bifacial construction captures light from both front and rear surfaces. Projects on reflective surfaces such as concrete, white roofs or light gravel can benefit from increased kilowatt hour output.

Optimized for modern high voltage systems: With a 1500 volt maximum system voltage, this module fits long strings and utility scale arrays. Higher DC voltage enables lower balance of system costs and increased inverter efficiency.

Durable construction for harsh climates: An IP68 junction box, anodized aluminium frame and 2 millimetre glass ensure dependable protection. The panel operates from minus 40 to 85 degrees Celsius and handles demanding outdoor conditions.

How It Works

The BYD NLBK-36 570 solar panel converts sunlight into usable direct current power through high efficiency N-type TOPCon cells. When sunlight hits the monocrystalline cells on the front surface, electrons are energized and flow through the module circuit. The bifacial design allows the rear side to capture additional light reflected from the ground or nearby surfaces. This rear side contribution increases the total power output compared with traditional monofacial modules. Electrical energy produced by the module flows through the IP68 junction box and MC4 compatible cables to the string wiring. An inverter then converts the direct current into alternating current suitable for buildings or grid connection. The panel is engineered to perform across a wide temperature range with carefully controlled temperature coefficients. This helps maintain consistent output during hot summer days and colder seasons on site.

N-Type TOPCon cell conversion: N-type TOPCon cells feature passivated contacts that reduce recombination losses. More of the absorbed sunlight gets converted into useful electrical energy rather than wasted as heat. The low degradation characteristics of N-type silicon maintain performance for many years of operation.

Bifacial rear side energy capture: The panel includes a rear side that responds to reflected and diffuse light behind the array. On bright, reflective sites, this rear side can add meaningful extra energy production. Designers can position the module with adequate height and spacing to maximize bifacial gain.

System integration and protection: Current produced by the cells is collected in the junction box and routed through 4 square millimetre cables. The IP68 rated enclosure protects diodes and connections from moisture and dust ingress. In the array, strings of modules connect to inverters operating at up to 1500 volts system voltage.

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.
