Product Overview

The QSOLAR QS550-110HM10 550W monocrystalline solar panel is engineered for high energy yield in modern PV systems. This high-output module combines 550 watt peak power with module efficiency up to 21.1 percent for reliable energy production on constrained roofs and commercial arrays. Its monocrystalline 210 mm half-cut cells, advanced PERC technology, and optimized temperature behavior support strong performance in real operating conditions. A robust anodized aluminum frame, 3.2 mm tempered glass with anti-reflection coating, and IP68 junction box help protect the module in harsh climates. With a 12 year product warranty and a 25 year power warranty, this module is designed to deliver dependable long term solar savings. The QS550-110HM10 integrates easily into 1500 V DC systems and suits residential, commercial, agricultural, and light industrial projects seeking bankable, cost effective solar power.

Key Benefits

High power density for smaller arrays: Up to 550 Wp per module allows strong system output with fewer panels and reduced racking and wiring needs.

Excellent conversion efficiency: Module efficiency around 21 percent maximizes production on rooftops and ground mounts with limited space.

Reliable long term performance: The 25 year power warranty with an 84.8 percent guaranteed output ensures predictable energy yield over the life of the system.

Low degradation and tight tolerance: A low annual degradation rate and positive power tolerance from 0 to +0.83 percent help secure more real world kilowatt hours.

Durable construction for harsh sites: Tempered glass with anti reflection coating, anodized aluminum frame, and IP68 junction box support operation in demanding outdoor environments.

Flexible integration and design range: A broad power range from 405 to 660 Wp and compatibility with 1500 V systems simplify string design and future system expansion.

How It Works

This monocrystalline solar panel converts sunlight into direct current electricity using high efficiency silicon cells. When sunlight reaches the 210 mm half cut cells, photons transfer energy to electrons in the silicon lattice. These energized electrons move through an internal electric field and create a steady DC current at the module output leads. The panel operates at a maximum power point of 550 Wp under standard test conditions, with a Vmpp of 31.6 volts and Impp of 17.4 amps. In typical outdoor operation, the NOCT rating delivers around 417 Wp at 29.4 volts and 14.19 amps, supporting stable production in real weather conditions. The generated DC power is routed through MC4 connectors and 4 mm² solar cable to an inverter, which converts it into AC electricity for on site consumption or export to the grid.

Monocrystalline half cut cell design: The QS550-110HM10 uses monocrystalline PERC cells cut into halves to reduce resistive losses. This layout increases module efficiency and improves shade tolerance across the string, supporting higher energy yield in partial shading.

Optimized electrical operating points: At STC, the panel reaches 31.6 V at maximum power with 37.9 V open circuit voltage and 18.52 A short circuit current. Under NOCT, the operating point shifts to 29.4 V and 14.19 A, which helps the inverter track the maximum power point across varying temperatures and irradiance.

Protective materials and junction box: A 3.2 mm tempered glass front with anti reflection coating enhances light transmission while safeguarding the cells from impact and weather. On the rear side, an IP68 rated junction box and MC4 connectors maintain secure electrical connections and protect against dust and water ingress through many years of outdoor 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.

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.
