Rixing Electronics QJM445-144H(9BB) 445W Mono PERC Half‑Cell Solar Panel

Model QJM445-144H(9BB) | Mono PERC | 144 Half-Cell | Monofacial | 1500V System Voltage

445W

Max Power Output

20.5%

Module Efficiency

144 Cells

N-Type TOPCon

Product Overview

The Rixing Electronics QJM445-144H(9BB) 445W Mono PERC Half-Cell Solar Panel delivers reliable power with high efficiency for residential and commercial systems. As a robust 445W module, it suits rooftops, ground mounts, and small industrial arrays seeking dependable long term performance. Advanced monocrystalline PERC cells are arranged in a 144 half cell layout to reduce resistive losses and boost real world output. A multi busbar design improves current collection and enhances shade resilience across the module surface. The panel is engineered for 1500V system voltage applications, supporting modern string inverter architectures. Durable glass and frame construction allow operation in harsh weather, including strong wind and heavy snow conditions. This module offers an excellent balance of power density, quality, and value for new installations or system expansions.

Key Benefits

High Power Density: The 445W output provides strong generation from a compact footprint, ideal where roof space is limited.

Enhanced Half-Cell Design: The 144 half cell layout helps reduce internal losses and supports better performance under partial shading.

Optimized 9BB Cell Interconnection: Nine busbars improve current collection and lower series resistance, supporting stable long term energy yield.

Versatile System Integration: The 1500V system rating enables longer strings and reduced balance of system costs in many project designs.

Durable Outdoor Construction: A robust frame and weather resistant materials support dependable operation across varied climates and seasons.

How It Works

This Rixing Electronics QJM445-144H(9BB) solar panel converts sunlight into usable electricity through advanced monocrystalline PERC cells. When sunlight reaches the cell surface, photons are absorbed and release electrons inside the silicon structure. These electrons are guided by the panel’s nine busbar grid, creating a direct current electrical flow. The half cell configuration divides the module into two sections, reducing current in each path and limiting resistive losses. This structure helps sustain higher output, especially when part of the panel is shaded. The generated direct current is routed through junction box connections to the system wiring. A compatible inverter then converts the direct current into alternating current for building loads or grid export. Throughout this process, tempered glass protection, encapsulant layers, and a durable backsheet maintain electrical insulation and environmental resistance for the module.

Monocrystalline PERC Energy Conversion: High quality mono PERC cells capture sunlight efficiently and convert it into direct current electricity. A passivated rear surface reflects unabsorbed light back into the cell, increasing energy harvest.

Half-Cell and 9BB Current Management: The 144 half cell arrangement reduces current in each cell string, lowering resistive losses and heat. Nine busbars on each cell shorten current paths, supporting better output under real site conditions.

System Integration and Power Delivery: The panel connects to string wiring through a rear junction box with pre attached leads. Once wired to an inverter, produced energy can power on site loads, charge batteries, or feed the utility grid.

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.
