N-Type TOPCon

Product Overview

The Haier NHO144-570MN 550W TOPCon monocrystalline solar panel delivers high performance for commercial and residential arrays. This 550W solar panel combines advanced TOPCon cell technology with half-cut monocrystalline cells for excellent efficiency and reliability. Engineered around a robust 144 cell layout and 1500V system rating, it supports large scale strings with reduced balance of system costs. The module efficiency reaches 21.9 percent, helping more power fit into limited roof or ground space. A low annual degradation rate supports 87.4 percent power after 30 years under standard test conditions. The durable anodized aluminium frame, 3.2 millimetre tempered glass, and IP68 junction box enable dependable outdoor operation. With a wide operating temperature range and optimized temperature coefficients, this panel maintains strong output across demanding climates. It is an ideal choice where dependable long term energy yield and dependable quality are required.

Key Benefits

High power density for limited space: The 550 Wp output and up to 22.45 percent efficiency help maximise energy from tight roofs and sites.

Advanced TOPCon cell technology: TOPCon cells reduce power loss, deliver higher conversion efficiency, and enhance performance in real world conditions.

Long term energy yield: The low 0.42 percent annual degradation supports 87.4 percent output after 30 years of operation.

Robust construction for harsh environments: Anodized aluminium frame, 3.2 mm tempered glass, and IP68 junction box support dependable outdoor durability.

Flexible system design: The 1500 V system voltage and 25 A series fuse rating support longer strings and efficient BOS design.

Wide application range: Suitable for commercial rooftops, industrial plants, ground mounts, and large residential systems.

How It Works

The Haier NHO144-570MN 550W TOPCon monocrystalline solar panel converts sunlight into electrical energy through high efficiency TOPCon cells. When light reaches the 144 half cut monocrystalline cells, electrons are excited and create direct current power. The half cut layout reduces resistive loss and improves shade tolerance across the module surface. At standard test conditions the panel reaches 550 Wp at 41.5 volts and 13.26 amps. The generated DC flows through the integrated MC4 connectors and solar cables into a compatible inverter. There the power is converted into usable alternating current for onsite loads or export to the grid. The panel continues operating within a wide temperature range, using optimized temperature coefficients to limit power loss in heat or cold. Over decades of operation, the low degradation profile supports stable production and better lifecycle energy yield.

High efficiency TOPCon cell conversion: N-type TOPCon monocrystalline cells capture sunlight and convert it into direct current with reduced recombination losses. The advanced passivated contacts improve voltage and efficiency, raising overall module output across the power range.

Half-cut cell and string layout: The 144 half cut cells are wired to limit resistive loss and improve tolerance to partial shading. This layout helps maintain current flow so sections of the panel continue producing when some areas receive less light.

System integration and protection: Power from the panel passes through three diode junction boxes to protect against reverse current. MC4 connectors simplify series connections up to the 1500 V system rating and 25 A series fuse limit, ensuring safe integration with inverters and combiner boxes.

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.

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.
