Product Overview

The QPower QPM-650S 650W PERC monocrystalline solar panel is designed for high power density and long term reliability in demanding climates. This advanced module uses 132 half cut monocrystalline PERC cells to deliver strong performance on residential, commercial, and utility scale projects. A rated maximum power of 650 Wp and panel efficiency up to 21.41% help reduce the number of modules required on each array. Engineered with a robust anodized aluminium frame and 3.2 mm tempered glass, the panel is suitable for harsh outdoor environments. Its 1500 V system voltage rating and 30 A series fuse rating support large modern string inverters. The QPM-650S is backed by a 12 year product warranty and an extended power warranty with slow degradation, supporting long term energy production. Manufacturing in Uzbekistan under the QPower brand ensures reliable regional supply and consistent quality. This module is ideal for projects where high output, compact footprint, and dependable warranty protection are priorities.

Key Benefits

High power density for fewer modules: With up to 650 Wp output per module, fewer panels are needed to reach target system sizes, saving mounting hardware and installation time while maximising roof or ground space utilisation.

Efficient PERC monocrystalline cells: PERC cell technology and monocrystalline silicon deliver panel efficiencies from 20.76% to 21.41%, providing strong energy yields even on sites with limited installation area.

Robust mechanical construction: The 3.2 mm tempered glass, anodized aluminium frame, and IP68 junction box help protect the module against moisture, dust, and mechanical impacts in challenging environments.

Long term performance assurance: A 12 year product warranty and power warranty of 92% at year 12 and 83% at year 30 support bankable lifecycle performance for owners and investors.

Wide application flexibility: The high system voltage rating of 1500 V and 30 A series fuse rating support integration into modern string and central inverter platforms for residential, commercial, and utility scale arrays.

How It Works

This module converts sunlight into usable electrical energy through high efficiency monocrystalline PERC cells connected in a carefully engineered circuit. Each of the 132 half cut cells is manufactured from premium silicon designed for stable long term performance. When light reaches the cell surface, photons are absorbed and release electrons, creating direct current electricity. The PERC structure uses a passivated rear surface that reflects unabsorbed light back into the cell, increasing energy capture. The internal wiring and cell layout are optimised to limit resistive losses, supporting the module’s 650 Wp rating under standard test conditions. Generated current is collected through the junction box and then routed to the external DC cabling, which connects to compatible inverters or charge controllers. Once inverted to alternating current, the electricity can power loads or be fed into an electrical grid under net metering or power purchase arrangements. Across its lifetime, the panel maintains energy production with a controlled degradation rate of approximately 0.57% per year, supporting predictable yields.

PERC monocrystalline cell conversion: Monocrystalline cells offer a uniform silicon structure that supports higher carrier mobility and efficiency. The PERC rear surface treatment reduces electron recombination and reflects unused light, helping the module achieve high power and efficiency ratings across the series.

Half cut cell and string configuration: The 132 cells are half cut to reduce current per cell, which lowers resistive loss and improves thermal behaviour. This configuration can also provide better shade tolerance on partially shaded arrays compared with full cell layouts, supporting more stable energy output.

System integration and protection: The junction box houses three bypass diodes that help protect the cells under partial shading or mismatch. The IP68 enclosure and robust connectors support reliable operation in outdoor conditions, while the 1500 V rating allows longer strings and reduced balance of system costs.

Customer Success Stories

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.

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.

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!
