Product Overview

The TSEC TS72-CMH-590 H1 590W TOPCon Monocrystalline Solar Panel is engineered for projects that demand high power density and long term reliability. It uses advanced N type TOPCon cell technology to deliver impressive module efficiencies up to 22.8 percent. This helps sites maximize output when roof or ground space is limited. The 144 half cell layout, low temperature coefficients and strong mechanical design support stable production in a wide range of climates. A competitive 12 year product warranty is paired with a 30 year performance warranty. Degradation is tightly controlled, with 91.4 percent power guaranteed at year twenty and 87.4 percent at year thirty. This module is suitable for commercial rooftops, industrial systems and utility scale solar farms where bankable performance matters.

Key Benefits

High power in a compact footprint: Each module provides up to 590 watts of output while maintaining a slim 2278 by 1134 millimeter format. This increases system capacity without requiring additional mounting space.

Advanced TOPCon cell efficiency: N type TOPCon cells deliver conversion efficiencies between 22.1 and 23.4 percent across the series. Better low light response and lower LCOE are achieved compared with conventional P type modules.

Excellent temperature performance: A low Pmax temperature coefficient of minus 0.29 percent per degree Celsius helps preserve output on hot days. Stable generation is maintained even in harsh summer conditions.

Durable build for demanding sites: An anti salt mist frame, IP68 junction box and 5400 pascal mechanical load rating support tough environments. The module resists coastal corrosion and heavy wind or snow loads when properly installed.

Bankable long term warranties: A 12 year materials and workmanship warranty is complemented by a 30 year linear power warranty. The total degradation rate is limited to 0.42 percent per year, giving investors strong confidence in long term yield.

How It Works

This module converts sunlight into electricity using high efficiency N type TOPCon monocrystalline solar cells. Incoming photons strike the 182 millimeter cells and release electrons within the crystalline silicon structure. The cell architecture guides these electrons into an electric circuit, producing direct current power at the module terminals. Half cell design reduces resistive losses and mitigates shading impact, so more usable energy is harvested during real world operation. At standard test conditions the TS72-CMH-590 H1 delivers 590 watts, with a maximum power voltage of 44.49 volts and a maximum power current of 13.27 amperes. Integrated bypass diodes protect strings from energy losses caused by localized shading. The generated DC power can then be routed to string inverters, central inverters or hybrid inverters that match the 1500 volt system design.

N-Type TOPCon cell architecture: The module uses N type TOPCon monocrystalline cells, which feature a passivated contact structure. This design reduces recombination losses and improves carrier collection, especially under weak illumination. As a result, output stays more stable through mornings, evenings and cloudy conditions.

144 half cell layout and stringing: Cells are arranged as 144 half cut devices in a 6 by 24 configuration. Half cell strings operate at lower current, which minimizes resistive power loss and improves shade tolerance. This layout also helps reduce hotspots and enhances overall reliability.

Module protection and system integration: A multi layer stack of PV coated glass, low WVTR encapsulant film and a durable backsheet protects the cells. The IP68 rated junction box houses three bypass diodes that limit power loss when sections are shaded. Factory fitted 1500 millimeter cables and EVO 2 compatible connectors simplify integration into high voltage arrays.

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.

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!
