Quality Solar QS600-120HM10 600W Monocrystalline Solar Panel

Model QS600-120HM10 | Monocrystalline | 120 Cells | Monofacial | 1500V System Voltage

600 Wp
Max Power Output
21.2%
Module Efficiency
Monocrystalline
High-Output Cell Technology

Product Overview

The Quality Solar QS600-120HM10 is a high-efficiency monocrystalline solar panel built for strong power output and dependable long-term performance. It delivers up to 600 Wp of rated power, making it a strong choice for demanding residential, commercial, and utility-scale projects. Its 21.2% module efficiency supports excellent energy harvesting in limited roof or ground space. The panel includes a positive power tolerance of 0 to +0.83%, which helps ensure reliable output from module to module. It is engineered for harsh environments, with a wide operating temperature range and durable construction materials. A 12-year product warranty and 25-year power warranty add further confidence for long-term solar investment.

Key Benefits

High Power Output: The module reaches 600 Wp, helping reduce the number of panels needed.

Strong Efficiency: Its 21.2% efficiency supports more energy generation from available surface area.

Positive Tolerance: A 0 to +0.83% tolerance improves output consistency across installations.

Durable Construction: Tempered low-iron glass, anodized aluminium, and IP68 protection support tough outdoor use.

Long-Term Reliability: The 25-year linear power warranty is backed by a 84.8% total degradation rate specification.

How It Works

This monocrystalline solar panel converts sunlight into usable electricity through a high-performance cell layout designed for efficient energy capture. Each cell works together to generate direct current, which can then be converted by an inverter into alternating current for home or business use. The panel design helps reduce internal mismatch losses and shadow-related losses, which can improve real-world production. Its positive tolerance and strong temperature performance support stable output throughout the day. Built-in durability features also help it perform reliably in challenging weather conditions. This makes the module a practical option for projects that need dependable generation and long service life.

Solar Conversion: The monocrystalline cells absorb sunlight and convert it into direct current electricity. The 120-cell layout supports strong electrical performance and efficient energy collection.

Power Flow: The module produces electricity at 34.4V Vmpp and 17.44A Impp under standard test conditions. This output is suitable for modern solar system designs.

Durability Support: Tempered glass, an anodized aluminium frame, and IP68 junction box protection help the panel handle outdoor exposure. These features support steady operation in demanding environments.

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.
