QPower QPM-660S 660W Monocrystalline PERC Solar Panel

Model QPM-660S | PERC | 132 Cells | Monocrystalline | 1500V System Voltage

660 Wp
Max Power Output
21.25%
Module Efficiency
132
Monocrystalline Cells

Product Overview

The QPower QPM-660S is a high-output solar panel built for demanding commercial and utility-scale projects. This monocrystalline module uses PERC technology to deliver strong conversion performance and dependable energy generation. Its 660 Wp rating helps reduce the number of modules needed for large installations. The panel also offers a 21.25% efficiency level, which supports better space utilization on modern solar arrays. With a robust 1500V system voltage rating, it is suitable for advanced string designs and larger site layouts. The black anodized frame and tempered glass construction support long-term durability in challenging outdoor environments. The model is designed for stable performance across a wide operating temperature range. It is a practical choice for buyers seeking high power density and reliable long-term output.

Key Benefits

High Power Output: The 660 Wp rating supports strong energy production for large-scale solar systems.

Space-Efficient Design: High efficiency helps maximize power generation where roof or ground space is limited.

Durable Construction: Tempered glass, a black anodized aluminium frame, and a strong build improve outdoor reliability.

Long-Term Value: A 12-year product warranty and power warranty support confidence in long-term operation.

Stable Electrical Performance: Low temperature coefficients help maintain output as module temperatures rise.

Project-Friendly Format: The 132-cell configuration supports efficient use in modern commercial solar architectures.

How It Works

The QPM-660S converts sunlight into electricity through monocrystalline cells arranged in a high-density module layout. PERC technology improves light capture by allowing more photons to contribute to power generation. This helps the panel maintain strong output during normal operating conditions. The module is engineered to operate across a wide temperature range, which supports performance in hot and cold climates. Its electrical design is intended for efficient string integration, while the 1500V system voltage allows compatibility with larger solar arrays. The panel’s protective materials also help reduce stress from outdoor exposure. Together, these features make the module suitable for stable, long-term energy production.

Light Absorption: Monocrystalline cells capture sunlight efficiently. PERC enhancement improves rear-side light utilization for better output.

Power Conversion: The module converts absorbed solar energy into direct current electricity. Its electrical ratings support reliable system design and integration.

System Integration: The panel can be connected in series strings for larger arrays. Its 1500V maximum system voltage supports modern utility and commercial installations.

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.

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.
