IREX IRM60H3-445 440-455W PERC Monocrystalline Solar Panel

Model IRM60H3-445 | PERC | 120 Half-Cell | Monocrystalline | 1500V System Voltage

445 Wp

Max Power Output

20.56%

Module Efficiency

120

Monocrystalline Cells

Product Overview

The IREX IRM60H3-445 is a high-efficiency monocrystalline solar panel built for dependable energy production. It uses advanced PERC technology and a half-cut cell design to improve performance under real-world conditions. With a rated output of 445 Wp, this module balances strong power generation with compact dimensions. The panel is designed for modern residential, commercial, and utility-scale solar projects. Its 20.56% efficiency helps maximize energy yield from limited roof or site space. The product is supported by a 12-year product warranty and a 25-year power warranty. That long service life makes it suitable for long-term solar investment planning. The panel also carries a positive power tolerance, which supports consistent output expectations.

Key Benefits

High Power Output: Delivers up to 445 Wp for strong energy production across demanding solar applications.

Efficient Space Use: Its 20.56% efficiency helps generate more electricity from the same installation area.

PERC Half-Cut Design: PERC and half-cut cell architecture improve electrical performance and reduce power losses.

Long-Term Reliability: A 12-year product warranty and 25-year power warranty support long service confidence.

Built for Harsh Conditions: The module operates from -40 to 85 °C and supports a 1500 V system voltage.

How It Works

This solar module converts sunlight into usable DC electricity through monocrystalline silicon cells. The PERC structure improves light capture by reflecting unused photons back into the cell. Half-cut cell technology reduces electrical resistance and helps limit internal losses. That design also reduces the impact of partial shading on overall output. When sunlight hits the panel, the cells generate current and voltage together. The module then delivers stable power through its junction box and protected diode layout. Its temperature coefficients help define performance changes as operating conditions shift. Those values are useful for system design and long-term yield expectations. The panel is engineered for efficient operation across rooftops, ground mounts, and other solar installations.

Sunlight Conversion: The monocrystalline cells absorb sunlight and convert it into direct current electricity. This process supports steady energy generation throughout the day.

PERC Enhancement: PERC technology improves internal light utilization. More photons are used effectively, which supports higher output.

Half-Cut Optimization: Half-cut cells lower electrical resistance and reduce power loss. They also improve performance when part of the panel is shaded.

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.
