IREX IRM60H3-450 450W PERC Monocrystalline Solar Panel

Model IRM60H3-450 | PERC | 120 Half-Cell | Monocrystalline | 1500V System Voltage

450 Wp

Max Power Output

20.79%

Module Efficiency

120

Half-Cut Cells

Product Overview

The IREX IRM60H3-450 is a high-efficiency monocrystalline solar panel built for dependable long-term energy production. It uses advanced PERC technology and a half-cut cell design to improve output stability and reduce power losses. With a rated power of 450 Wp, this module suits commercial rooftops, utility-scale systems, and other demanding solar applications. Its 20.79% module efficiency supports strong energy yield in limited space. The panel is engineered with durable materials, including tempered glass and an anodized aluminium frame. A 12-year product warranty and 25-year power warranty add confidence for project planning and ownership.

Key Benefits

High power output: Delivers 450 Wp for strong generation across residential and commercial installations.

Efficient design: The 20.79% efficiency rating helps maximize production from valuable roof space.

Advanced PERC technology: PERC cells improve light capture and support better performance under real-world conditions.

Half-cut cell architecture: Half-cut cells reduce internal losses and support improved shading tolerance.

Durable construction: Tempered glass, an anodized aluminium frame, and robust build quality support long service life.

Strong warranty support: A 12-year product warranty and 25-year power warranty provide added peace of mind.

How It Works

This solar panel converts sunlight into usable electricity through monocrystalline photovoltaic cells. The PERC layer improves the way light is absorbed and reflected inside each cell. That helps the module generate more power from the same surface area. The half-cut layout also supports lower resistance losses during operation. It can improve performance when partial shading affects part of the module. The panel is designed for consistent output across a wide temperature range. Its electrical characteristics support safe integration in modern solar systems. The build quality also helps the panel withstand everyday environmental stress.

PERC cell operation: The rear cell structure improves internal light use. This supports higher conversion efficiency and better energy harvest.

Half-cut current flow: Splitting the cells helps reduce resistive loss. It also supports more stable performance under shaded conditions.

System integration: The module operates with a 1500V maximum system voltage. This makes it suitable for larger solar arrays and professional installations.

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.
