N-Type TOPCon

Product Overview

The BYD NLBK-36 585W N-Type TOPCon bifacial monocrystalline solar panel is engineered for commercial and utility scale arrays where every watt matters. High efficiency N-type TOPCon cells are combined with bifacial technology to harvest energy from both sides of the module. This design increases total energy yield compared with conventional monofacial panels under the same conditions. A maximum power output of 585 watts and module efficiency up to 23.23 percent allow more generation from limited roof or ground space. The panel is built with 144 monocrystalline half-cells, durable 2 millimeter glass and a robust anodized aluminium frame. It operates reliably in a wide temperature range from minus forty to eighty five degrees Celsius. Degradation is tightly controlled with a total rate of only 12.6 percent over thirty years, leaving 87.4 percent of the initial power output still available. That makes this module a strong choice for long term projects that demand dependable performance, bankability and a lower levelized cost of energy.

Key Benefits

High power density for limited spaces: With a maximum power rating of 585 watts and efficiency up to 23.23 percent, this panel delivers more generation per module. Fewer panels can be used for the same system size, which helps reduce mounting, cabling and labor costs on large sites.

Bifacial energy gain: Bifacial construction allows light capture on both the front and rear sides of the module. Reflected light from bright surfaces or ground coverings is converted into extra power, improving annual energy yield compared with similar monofacial modules.

Stable long term performance: An advanced N-type cell design and low temperature coefficients support more stable output over time. The thirty year power warranty with 87.4 percent remaining output reflects the slow degradation rate of only 0.42 percent per year after the first year.

Robust construction for harsh climates: The 2 millimeter solar glass, anodized aluminium frame and IP68 rated junction box are designed for demanding sites. Operation from minus forty to eighty five degrees Celsius allows reliable performance in both hot and cold environments.

Flexible system integration: The 1500 volt maximum system voltage and 30 amp series fuse rating support long strings and efficient array layouts. Compatibility with modern string inverters simplifies design for commercial rooftops, ground mounts and utility projects.

How It Works

This BYD NLBK-36 585W solar panel converts sunlight into usable electrical power through high efficiency N-type TOPCon monocrystalline cells. When sunlight reaches the front glass, photons strike the silicon lattice and release electrons. These electrons are guided through the cell structure and collected as direct current energy at the module’s terminals. The bifacial design also collects light that reaches the rear side, including reflected and scattered radiation from the surrounding environment. Both contributions are combined into the total current output of the panel. The electrical characteristics, such as voltage at maximum power of 44.9 volts and current at maximum power of 13.03 amps, describe how the module behaves under standard test conditions. In a real installation, multiple modules are wired in series and parallel to reach the required system voltage and power. An inverter then converts the direct current into alternating current suitable for building loads or grid export. Throughout operation, temperature coefficients determine how output changes as the cells heat up or cool down, ensuring predictable performance in different climates.

N-Type TOPCon cell conversion: The panel uses advanced N-type TOPCon monocrystalline cells to convert light into electricity. These cells have a passivated contact structure that reduces recombination losses and improves carrier collection. As a result, more of the incoming solar energy is converted into electrical power instead of being lost as heat.

Bifacial rear side generation: The module features an active rear side that responds to reflected light from surfaces below and around the array. When the rear cells receive this additional light, they generate extra current that supplements the front side power. This mechanism can significantly boost total energy yield on high albedo surfaces like concrete or light colored gravel.

Thermal and electrical behavior: The output of the module varies with temperature and irradiance according to its rated coefficients. A temperature coefficient of power of minus 0.278 percent per degree Celsius means output decreases gradually as cells warm above standard conditions. Careful array design, including airflow around the panels, helps keep temperatures moderate and supports higher real world production.

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.
