Product Overview

The Rixing QJM340-72 340W monocrystalline solar panel is engineered for reliable daily energy yield. This high quality module from Cixi City Rixing Electronics Co., Ltd. offers a balanced mix of power and efficiency for many projects. With a rated maximum power output of 340 Wp, it fits residential, commercial, and small industrial systems. Module efficiency starts at 17.52 percent and can reach 18.04 percent within the series range. The panel uses 72 monocrystalline cells, which help deliver stable performance in real world conditions. Its robust aluminum frame and tempered glass front are designed to handle demanding environments. The QJM340-72 panel is well suited for grid tied arrays and off grid battery based systems when paired correctly. Installers benefit from its familiar 72 cell layout and standard electrical characteristics. This product offers a dependable solution for users seeking long term solar performance from a trusted Chinese manufacturer.

Key Benefits

Optimized 340W power class: The 340 Wp rating fits many roof sizes and string designs. It delivers significant energy production without excessive array footprint.

Proven 72 cell format: The 72 cell layout is widely used and well understood by installers. It simplifies system planning, mounting, and inverter matching.

High conversion efficiency: Module efficiency from 17.52 to 18.04 percent supports higher power density. More energy can be produced from limited installation surfaces.

Reliable electrical performance: A Vmpp of 36.7 V and Impp of 9.27 A ensure predictable array behavior. The electrical profile suits many common inverter inputs and charge controllers.

Durable mechanical design: The 1956 x 992 x 40 mm frame is designed for long term stability. The module size aligns with standard mounting systems and racking accessories.

Flexible power range options: Within the series, power ratings span 340 to 350 Wp. This enables easy mixing of panels from the same family where required.

How It Works

The Rixing QJM340-72 monocrystalline solar panel converts sunlight into usable electrical power. Its 72 high efficiency silicon cells are wired to provide a stable voltage and current output under standard test conditions. When sunlight strikes the cell surface, photons transfer energy to electrons in the semiconductor material. These energized electrons are directed through an internal electric field, creating direct current power at the module terminals. The panel delivers a maximum power output of 340 Wp when operating near 36.7 V and 9.27 A. System designers then connect several panels in series and parallel strings to achieve the desired array voltage and power. The generated DC power is routed to an inverter or charge controller, which conditions the energy for grid connection or battery storage. Throughout operation, the engineered cell layout and durable encapsulation maintain performance and help resist environmental stress.

Monocrystalline cell conversion: Each of the 72 monocrystalline cells captures incoming light and converts it into electrical energy. The uniform crystal structure promotes efficient charge movement and helps reduce internal resistance within the cells.

Power optimization at Vmpp and Impp: The panel is designed to deliver its best power at 36.7 volts and 9.27 amps. Inverters track this operating point using maximum power point tracking, which helps maximize daily energy yield across changing conditions.

System integration and voltage window: With an open circuit voltage of 44.04 volts and a short circuit current of 9.92 amps, string design stays straightforward. Installers size strings to remain within inverter or controller input limits under cold and high irradiance conditions.

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.
