Monocrystalline

Product Overview

The SUNEX 450-144M is a monocrystalline solar panel built for dependable energy generation. It delivers a maximum power output of 450 Wp and uses 144 cells for efficient solar capture. The module is designed with a compact 35 mm frame profile and a large-format layout. This makes it suitable for space-conscious rooftop and commercial installations. Its power tolerance of -3% to +3% supports consistent performance. The panel is manufactured for customers seeking stable output and practical installation value. SUNEX Solar Energy supplies this module from the UAE market.

Key Benefits

High Power Output: The module provides 450 Wp of maximum power for strong energy production.

Monocrystalline Design: The cell technology supports efficient conversion and reliable daily performance.

Controlled Power Tolerance: A -3% to +3% tolerance helps keep output within a predictable range.

Large Cell Count: The 144-cell format supports balanced voltage and current performance.

Installation-Friendly Dimensions: The 2094 x 1038 x 35 mm size suits many modern roof and project layouts.

How It Works

This solar panel works by converting sunlight into electrical energy through its monocrystalline cells. Light enters the module and activates the semiconductor material inside each cell. That process generates direct current power for compatible solar systems. The panel then delivers power through a stable operating range defined by its electrical ratings. Its 144-cell structure helps support voltage levels needed for efficient system design. The module is intended for straightforward integration into grid-tied or off-grid applications. Its performance data helps installers match the panel to the correct inverter and array configuration.

Solar Conversion: Sunlight is absorbed by the monocrystalline cells and converted into DC electricity. The cell design supports efficient energy capture across the panel surface.

Power Delivery: The module produces a maximum power of 450 Wp at its rated operating point. Voltage and current values define how the panel behaves in real system conditions.

System Integration: The panel can be arranged in strings based on its electrical characteristics. This helps installers design arrays that meet project voltage and current requirements.

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.
