Product Overview

The TSEC TS66-CMH-525 H1 525W N-Type TOPCon monocrystalline solar panel is engineered for projects that demand high power density and long-term reliability. This advanced module uses N-type TOPCon cell technology and a 132-cell layout to deliver strong performance in a compact footprint. With a maximum output of 525 Wp and module efficiency of 22.1%, it supports space-constrained residential, commercial, and industrial rooftops. The panel is designed for 1500V systems, allowing flexible string design and reduced balance-of-system costs. Made in Taiwan, it combines robust construction, optimized thermal behavior, and low annual degradation for dependable energy production over decades.

Key Benefits

High power density per module: Deliver up to 525 Wp from a single panel with 22.1% module efficiency, enabling more power on limited roof space.

Advanced N-type TOPCon technology: N-type TOPCon monocrystalline cells offer better temperature behavior, lower degradation, and higher energy yield over the system lifetime.

Enhanced low-light performance: Optimized cell and glass design support stronger output in cloudy, early morning, and late afternoon conditions, improving annual kWh production.

Durable construction for harsh sites: The module uses an anti-salt mist frame, IP68 junction box, and high mechanical load rating, making it suitable for coastal and exposed installations.

Long-term performance guarantees: A 12-year product warranty and 30-year linear power warranty with low annual degradation help protect your investment and forecast returns confidently.

How It Works

This TSEC TS66-CMH-525 H1 solar panel converts sunlight into electricity using high-efficiency N-type TOPCon monocrystalline cells arranged in a 6x22 layout. When light hits the 182 mm cells, it generates direct current, which is then routed through the integrated IP68 junction box and cables to your inverter. The inverter converts the DC power to AC power that can be used onsite or exported to the grid. Optimized temperature coefficients ensure relatively stable power output as the module heats up in real-world operation. The low degradation rate preserves output year after year, supporting predictable long-term energy yields for residential, commercial, and utility-scale systems.

N-Type TOPCon monocrystalline cells: The module uses N-type TOPCon silicon cells that reduce carrier recombination losses and resist light-induced degradation. This structure enables higher efficiency and more stable performance over time than conventional cell types.

Optimized electrical design: At standard test conditions, the panel delivers 525 Wp with a maximum power voltage near 40.25 V and current around 13.05 A. This balance of voltage and current allows flexible string configuration with modern 1500V inverters and helps reduce overall system losses.

Robust module architecture: A coated front glass, low water vapor transmission encapsulant, and durable backsheet protect the cells from moisture and mechanical stress. The IP68 junction box with three bypass diodes manages shading impacts and improves energy harvest under partial shading conditions.

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.
