N-Type TOPCon

Product Overview

The Znshine Solar 440W N-Type TOPCon Bifacial Solar Panel delivers exceptional energy density for modern residential and commercial systems. This advanced module features 108 half-cut N-type monocrystalline cells engineered with SMBB technology for superior current collection. Its bifacial double-glass design captures sunlight from both sides, potentially boosting energy yield by up to 25% depending on ground albedo. The full-black aesthetic ensures a uniform, sleek appearance that blends seamlessly with any roof architecture. Built to withstand harsh environments, this Tier 1 panel offers robust resistance against salt, ammonia, sand, and extreme humidity. With a maximum efficiency of 22.53%, it maximizes power output even in weak light conditions like haze or early morning. The panel includes a durable 2mm anti-reflection glass coating and a robust frame for high mechanical load ratings. It meets rigorous international safety standards including IEC 61215 and IEC 61730 for long-term reliability.

Key Benefits

High Bifacial Gain: Captures up to 25% additional power from the rear side based on installation surface reflectivity.

Superior Weak Light Performance: SMBB technology reduces busbar distance, enhancing power output during haze, clouds, or early morning.

Anti-PID Resistance: Advanced cell manufacturing and raw material quality ensure strong resistance against Potential Induced Degradation.

Harsh Environment Durability: Resistant to salt, ammonia, sand, high temperatures, and high humidity for reliable outdoor operation.

Premium Aesthetics: The full-black design offers a uniform appearance superior to conventional modules for modern installations.

How It Works

This solar panel converts sunlight into electricity using advanced N-type monocrystalline cells with TOPCon technology. The 16BB SMBB structure minimizes electrical resistance between busbars and finger grid lines to maximize current flow. Its bifacial design allows photons to strike both the front and rear glass surfaces, generating extra power from reflected light. The anti-reflection coating reduces light loss, ensuring more photons enter the cell to create electron flow. Robust double-glass construction protects internal components from moisture and mechanical stress over decades of operation. Temperature coefficients are optimized to maintain efficiency even when ambient heat rises significantly during summer days.

Photon Absorption: Sunlight hits the N-type cells, exciting electrons to create a direct current flow through the circuit.

Bifacial Energy Capture: Reflected light from the ground passes through the rear glass, generating additional power from the back side.

Current Collection: SMBB technology reduces the distance between busbars, improving electron collection and reducing power loss.

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.
