PERC Half-Cut Cells

Product Overview

The Elerix EXS-550MHC-B 550W PERC monocrystalline half-cut solar panel is designed for projects that demand high efficiency and long term reliability. This powerful module uses advanced mono PERC half cut cells to deliver a panel efficiency of 21.3% while maintaining a sleek black appearance. With a maximum system voltage of 1500 V and robust construction, it fits both residential and commercial installations. A linear power warranty ensures strong performance, with 92% output guaranteed after 12 years and 83% after 30 years. The EXS-550MHC-B is produced by Elerix Ltd. in the Czech Republic and is built to handle demanding climates including deserts, farmlands and coastal areas. Heavy snow and wind load resistance, together with an IP68 junction box, support dependable energy production throughout the panel lifetime.

Key Benefits

High power density: The 550 Wp output and 21.3% efficiency help maximise energy yield from limited roof or ground space.

Reliable long term performance: A 12 year product warranty and 30 year linear power warranty support investment security for owners.

Durable mechanical design: The tempered glass, anodized aluminium frame and IP68 junction box provide strong protection in harsh weather.

Enhanced safety and compatibility: A 1500 V system rating and 25 A series fuse rating suit modern string inverters and large scale arrays.

Optimised cell technology: PERC half cut cells reduce resistive losses and hot spot risk, improving real world performance and reliability.

How It Works

Sunlight hits the Elerix EXS-550MHC-B solar panel and is absorbed by its monocrystalline PERC half cut cells. The cells convert this solar energy into direct current electricity, which is then routed through the integrated junction box and DC cables to the inverter. At standard test conditions the module delivers up to 550 Wp, with a maximum power voltage of 42 V and current of 13.1 A. The high efficiency design means more of the incident light becomes usable power, even when installation space is limited. Temperature coefficients have been optimised so that power loss remains moderate as cell temperature rises. The robust frame, glass and encapsulation work together to protect the cells from mechanical stress and moisture, supporting stable performance over decades of operation.

Mono PERC half-cut cell architecture: Each 182 × 91 mm monocrystalline PERC cell is cut into half cells and arranged in a 144 cell layout. This layout reduces electrical resistance and lowers operating temperature, which increases output and decreases the risk of hot spots over time.

Energy flow and system integration: Generated DC power flows from the cell strings to the IP68 junction box, which contains three bypass diodes. These diodes help the panel continue operating when partial shading occurs, while the 1500 V system rating allows longer strings and reduced cabling costs.

Temperature and environmental resilience: The panel operates from -40°C to 85°C and uses a tempered glass front with 3.2 mm thickness. Power, voltage and current temperature coefficients are engineered so performance remains stable in heat, cold and changing irradiance throughout the year.

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.
