Product Overview

The TSEC TS66-CMH-550 H1 550W N-Type TOPCon monocrystalline solar panel delivers high efficiency for modern solar projects. This premium module is designed for commercial, industrial, and large residential systems that demand reliable long term output. Its advanced N-Type TOPCon cell technology helps achieve a module efficiency of up to 23.2 percent under standard conditions. The 550 watt power rating allows more energy to be produced from limited roof or ground space. A robust mechanical design supports demanding environments, including coastal applications with salt mist exposure. The module operates within a wide temperature range from minus 40 to plus 85 degrees Celsius. Degradation is kept low with a total degradation rate of only 0.42 percent per year over the warranty period. Backed by a 12 year product warranty and a 30 year linear power warranty, this panel is engineered for dependable energy generation. Made in Taiwan by TSEC Corporation, the TS66-CMH-550 H1 offers bankable performance for long term solar investments. Its combination of high power density, durable construction, and trusted certification makes it a strong choice for project developers and installers.

Key Benefits

High power density for limited space: With 550 watts of rated output, each module delivers strong energy yield from a standard footprint. This helps reduce module count and balance of system costs on space constrained roofs and ground mounts.

Advanced N-Type TOPCon efficiency: N-Type TOPCon cell technology improves conversion efficiency and reduces light induced degradation. This results in more stable long term production compared with many conventional P type modules.

Extended 30 year performance warranty: The panel includes a 12 year materials and workmanship warranty and a 30 year linear power warranty. Power output is guaranteed at 91.4 percent after 20 years and 87.4 percent after 30 years.

Robust 1500V system compatibility: A maximum system voltage of 1500 volts supports longer strings and reduced cabling. This is ideal for commercial rooftops and utility scale arrays seeking optimized system design.

Durable build for harsh environments: The module features an anti salt mist frame and IP68 junction box. It is tested for high mechanical loads and wide temperature ranges, supporting reliable operation in challenging climates.

Low temperature coefficient for hot climates: A Pmax temperature coefficient of minus 0.29 percent per degree Celsius helps maintain output on hot days. Energy yield stays more stable when cell temperatures rise.

How It Works

This TSEC TOPCon monocrystalline solar panel converts sunlight into usable direct current electricity using advanced N type cells. Each of the 132 monocrystalline cells is designed to capture photons efficiently across a broad light spectrum. When sunlight strikes the cell surface, an electric field drives electrons to flow and create current. The panel is optimized for stable performance under standard test conditions of 1000 watts per square meter and 25 degrees Celsius. Improved low light response helps maintain production during cloudy mornings and late afternoons. The PV coated front glass and low water vapor transmission encapsulant protect the cells from moisture and environmental stress. Current and voltage are collected through high quality busbars, then routed through an IP68 junction box. From there, compatible connectors link the module into series strings and arrays for system level power delivery. The result is a reliable, high efficiency module that can be integrated into grid tied or off grid systems with suitable inverters and controllers.

N-Type TOPCon cell architecture: N-Type TOPCon cells are engineered with a passivated contact structure that reduces recombination losses. This architecture supports higher efficiency and contributes to additional power gain compared with conventional cells of similar size.

Module construction and protection: The cells are laminated between a PV coated front glass and a durable backsheet using a low WVTR encapsulant. This construction limits moisture ingress and supports long term reliability under thermal cycling and humidity.

System integration and power flow: Three bypass diodes in the IP68 junction box help reduce power loss during partial shading. The module connects through EVO 2 compatible connectors into strings that feed an inverter, which then converts DC power into AC electricity for site loads or export.

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.
