N-Type TOPCon

Product Overview

The BYD NLBK-36 580W N-Type TOPCon Bifacial Monocrystalline Solar Panel is engineered for high performance in demanding commercial and utility projects. Its advanced N-type TOPCon cell technology delivers excellent efficiency and reliable power generation across a wide range of climates. With a rated maximum power of 580 watts, the module supports modern high-voltage arrays using a 1500 volt maximum system voltage. Bifacial construction allows the panel to harvest light from the front and rear sides, which increases total energy yield over the life of the system.

This BYD NLBK-36 580 panel offers a module efficiency of up to 22.45 percent, placing it among the most space efficient options on the market. The power range for the series spans 570 to 600 watts, giving designers flexibility in string sizing and layout. A robust anodized aluminum frame and 2 millimeter glass are combined with IP68 junction boxes for long term durability. The panel has been designed to operate from minus 40 to 85 degrees Celsius, making it suitable for hot deserts and cold northern sites alike.

The product warranty of 12 years protects against manufacturing defects, while a 30 year power warranty supports long term investment planning. Degradation is controlled, with 87.4 percent of initial power output maintained at the end of the warranty period. Tight power tolerance from 0 to plus 0.85 percent ensures consistent array behavior and reduces mismatch losses. With a manageable 32 kilogram weight and standard 2278 by 1134 millimeter footprint, this panel integrates smoothly into most mounting systems.

Key Benefits

High power density: The 580 watt nameplate rating and up to 23.23 percent series efficiency maximize energy output per module, allowing more power from the same roof or ground area.

Advanced N-type TOPCon cells: N-type TOPCon cell architecture reduces light induced degradation and improves low light behavior, supporting stable performance throughout the module lifespan.

Bifacial energy gain: Bifacial design captures reflected and diffuse light from the rear side, increasing total kilowatt hour production on reflective surfaces and optimized mounting structures.

Long term reliability: A 12 year product warranty and 30 year power warranty, with an 87.4 percent end of warranty power level, provide strong assurance for project owners and financiers.

Robust system integration: The 1500 volt maximum system voltage, 30 amp series fuse rating, and IP68 junction box allow safe integration into large commercial arrays with modern string inverters.

Wide operating temperature range: Operation from minus 40 to 85 degrees Celsius, combined with low temperature coefficients, supports reliable output in both hot and cold climates.

How It Works

The BYD NLBK-36 580 solar panel converts sunlight into direct current electricity using high efficiency monocrystalline N-type TOPCon cells. Each module contains 144 half cut cells arranged in series and parallel strings, which optimize voltage and current output. When sunlight strikes the cell surface, photons are absorbed and free electrons are generated, creating an electric current. The N-type cell structure reduces electron recombination losses and offers better resistance to common degradation mechanisms found in standard P-type cells.

The front side of the panel is protected by 2 millimeter tempered glass, which allows high light transmission while shielding the cells from weather and mechanical stress. The rear side of this bifacial module also participates in energy generation by capturing light reflected from the ground or nearby surfaces. An anodized aluminum frame adds rigidity, while the junction box and cables safely route the generated current toward inverters and balance of system components. When connected into strings, multiple modules feed DC power to a compatible inverter, which converts it into AC electricity for site loads or export to the grid.

N-type TOPCon cell conversion: N-type TOPCon cells use a passivated contact structure that reduces electrical losses at the cell surface. This structure allows more of the captured sunlight to be converted into usable electrical energy. Reduced susceptibility to light induced degradation helps maintain higher performance over many years of operation.

Bifacial energy capture: The module generates power from both the front and rear sides of the cell string. Front side energy comes from direct and diffuse sunlight, while the rear side harvests reflected light from surfaces such as concrete, white roofing, snow, or specialized reflective membranes. This additional backside contribution boosts total energy yield without increasing the footprint of the array.

System integration and performance stability: The module operates most efficiently around a nominal temperature of 45 degrees Celsius, with a low Pmax temperature coefficient of minus 0.278 percent per degree. As the module heats up, power loss remains limited compared with older technologies. The 1500 volt maximum system voltage and 30 amp series fuse rating allow long strings and efficient cabling layouts, while the IP68 junction box protects connections from moisture and dust.

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.
