QSOLAR QS505-150HM12 505W Monocrystalline Monofacial Solar Panel

Model QS505-150HM12 | Mono PERC | 150 Half-Cell Monocrystalline | Monofacial | 1500V System Voltage

505 W
Max Power Output
21.1%
Module Efficiency
150
N-Type TOPCon

Product Overview

The QSOLAR QS505-150HM12 505W monocrystalline solar panel is engineered for high performance in demanding projects. It delivers strong output in the 405 W to 660 W mono series and suits commercial and larger residential arrays. This half-cell module offers up to 21.1% panel efficiency for reliable energy yield on limited roof or ground space. A robust 1500 V DC system rating supports modern string designs with longer strings and reduced balance of system costs. The module uses premium tempered glass with anti-reflection coating to improve light capture and surface durability. Its anodized aluminium frame and IP68 junction box help ensure long term protection in harsh outdoor conditions. With a 12 year product warranty and a 25 year performance warranty, long term output is backed and bankable. The panel is produced by Ningbo Kanglite Electronics Co., Ltd. under the QSOLAR brand in China for global deployment. Installers can use this module in grid tied systems, hybrid setups, or off grid applications with suitable inverters. Across the MONO 210 series, consistent dimensions and electrical behaviour support easier system design and scaling.

Key Benefits

High power density for rooftops: The 505 W rating and up to 21.1% efficiency allow more power on limited space.

Reliable long term performance: A 25 year linear power warranty with 84.8% output at year 25 supports predictable yield.

Strong environmental resistance: The module is tested for high salt mist and ammonia exposure for coastal and farming sites.

Enhanced mechanical robustness: Design certification covers 2400 Pa wind load and 5400 Pa snow load for harsh climates.

Optimised cell layout and half cut design: Half cells reduce internal mismatch losses and help limit power loss from partial shading.

Flexible use across system sizes: The 1500 V DC rating and standard MC4 connectors simplify integration with many inverters.

How It Works

The QSOLAR QS505-150HM12 505W monocrystalline solar panel converts sunlight into usable DC electricity. Each monocrystalline half cell absorbs photons and releases electrons within the silicon structure. These electrons are directed through the cell busbars and connected in a series and parallel layout. The wiring inside the module combines voltage and current to reach 43 V at maximum power under STC. From the junction box, power flows through 4 mm² solar cables and MC4 connectors to the inverter. The inverter converts the DC electricity into AC power for on site loads or grid export. Under real world NOCT conditions, the panel delivers 382 W at 40.6 V and 9.43 A. Optimised materials and coatings help maintain performance over decades of outdoor exposure. System designers can connect many modules in series and parallel strings to achieve the target array size. Once installed correctly, the panel operates automatically whenever sufficient solar irradiance is available.

Monocrystalline half cell generation: High quality 210 mm monocrystalline cells are cut into halves to reduce electrical resistance. This layout improves current handling and helps lower operating temperature while sustaining output.

Optimised optical and glass design: The 3.2 mm low iron tempered glass features an anti reflection coating to capture more light. More light entering the cell surface translates into higher daily energy production and steadier yield.

Robust electrical path and protection: The rear mounted IP68 junction box protects diodes and connections from moisture and dust. Pre assembled MC4 connectors and UV resistant 4 mm² cabling allow quick and secure string wiring.

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.
