QPower QPM-655S 655W PERC Monocrystalline Solar Panel

Model QPM-655S | PERC Monocrystalline | 132 Half-Cell 210×105 mm | Monofacial | 1500V System Voltage

655 Wp
Max Power Output
Up to 21.41%
Module Efficiency
132 Cells
PERC Monocrystalline

Product Overview

The QPower QPM-655S 655W PERC monocrystalline solar panel delivers very high output and efficiency for utility and commercial projects. This high power module is engineered for large scale arrays where every square meter must generate maximum energy. With PERC cell technology, advanced 132 cell layout, and optimized electrical parameters, it supports reliable power production even under demanding site conditions. A robust anodized aluminium frame and tempered glass front help protect the module in challenging climates. The panel is suitable for installations in Uzbekistan and international markets that require dependable long term performance. A balanced design supports strong performance, durable construction, and efficient transport and handling on site.

Key Benefits

High power density for large arrays: With up to 655 Wp output and efficiency up to 21.41%, each module delivers strong production per unit area.

Efficient PERC monocrystalline technology: PERC cells help capture more sunlight and convert it efficiently into electricity, improving yield over the system life.

Reliable long term performance: A 12 year product warranty and long power warranty support investment security for commercial owners and developers.

Engineered for harsh environments: The operating temperature range from -40°C to 85°C allows use in very cold and very hot climates.

Versatile system integration: A maximum system voltage of 1500 V supports modern string inverters and optimized BOS costs on utility scale sites.

How It Works

This QPower QPM-655S solar panel converts sunlight into usable DC electricity using high efficiency PERC monocrystalline cells. Each of the 132 cells is wired together in a carefully designed circuit that balances voltage and current output. When exposed to sunlight, photons strike the PERC cells and release electrical charges that flow through the module’s busbars. These charges generate current that is delivered through the junction box and cables to a compatible inverter. The inverter then converts the DC output into AC power suitable for on site loads or for grid export. The module’s electrical characteristics, including voltage at maximum power and current at maximum power, are optimized to match contemporary 1500 V string inverters. Thermal coefficients and the wide operating temperature range help maintain stable production in real world conditions across seasons and climates.

PERC monocrystalline cell architecture: The module uses PERC technology, where a passivated rear surface reflects unabsorbed light back through the cell. This process increases internal light capture and raises overall efficiency compared with standard monocrystalline cells. The monocrystalline structure supports high performance and stable long term behavior in utility installations.

Optimized electrical output and string design: At standard conditions, the panel offers a maximum power of 655 Wp with a Vmpp of 38.11 V and Impp of 17.19 A. Open circuit voltage reaches 45.21 V, while short circuit current is 18.44 A, supporting flexible string sizing on 1500 V systems. These parameters enable longer strings, reduced cable runs, and lower balance of system costs.

Thermal behavior and durability in the field: Temperature coefficients of -0.36%/°C for Pmax and -0.26%/°C for Voc help limit power loss as cell temperatures rise. The operating temperature range from -40°C to 85°C allows the panel to function reliably in extreme cold and intense heat. A three diode junction box and IP rated protection help safeguard performance against localized shading and environmental exposure.

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.

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.

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.
