Product Overview

The Torri Solare Srl TRS 420-54M-H8N 420W PERC monocrystalline half-cell solar panel delivers high performance in a compact footprint that suits modern rooftops and commercial arrays. This half-cell module is engineered for strong energy yields, even under real world conditions with temperature shifts and partial shading. With an impressive panel efficiency of 21.5 percent, it helps maximise output from limited roof space and supports lower system balance of costs. The advanced monocrystalline cells and PERC technology are combined with a robust 1500 volt system rating for flexible array design. A 30 year product warranty and long term power guarantee give confidence for residential and commercial investors. Thanks to its durable construction, tempered glass and proven European brand heritage, this module is a reliable choice for long lasting solar projects. Installers benefit from a balanced voltage and current profile that integrates smoothly with modern string inverters. Homeowners and businesses gain a future ready panel that supports high efficiency solar systems with dependable long term production.

Key Benefits

High power density for tight spaces: The 420 Wp rating and 21.5 percent efficiency allow strong energy generation on compact residential and commercial roofs.

Long term performance assurance: A 30 year product warranty is paired with a 30 year power warranty, supporting long horizon project planning and returns.

Reliable energy yield over time: A total degradation rate of around 0.67 percent helps preserve strong output, so more power is delivered year after year.

Robust construction for demanding sites: Tempered glass with anti reflection coating, 4 mm thickness and a sturdy 26 kg frame support durability in varied climates.

Flexible system design and compatibility: The 1500 volt maximum system voltage and balanced electrical parameters simplify string sizing and integration with modern inverters.

How It Works

This Torri Solare Srl TRS 420-54M-H8N monocrystalline half-cell solar panel converts sunlight into usable DC electricity using high efficiency PERC cell technology. Each of the 108 half cut cells is sized at 182 by 91 millimetres and arranged to reduce resistive losses and improve shade tolerance. When sunlight hits the anti reflective tempered glass, more photons reach the silicon cells, where energy is captured and converted into electrical current. The module operates at a maximum power of 420 Wp with a voltage at maximum power of 31.9 volts and a current at maximum power of 13.17 amps. This energy then flows through integrated DC cables towards an inverter, which changes it into AC electricity ready for building loads or grid export. The panel is designed to perform within an operating temperature range from minus 40 to plus 85 degrees Celsius. Temperature coefficients control how output changes with heat, ensuring predictable performance across seasons and regions. By combining advanced cell design, durable materials and a high system voltage rating, the module supports efficient, bankable solar installations for many applications.

Monocrystalline PERC energy conversion: High purity monocrystalline cells absorb sunlight and convert it into DC electricity with enhanced internal reflection. The PERC structure improves light capture on the rear cell surface, increasing overall energy yield in real operating conditions.

Half-cell layout for lower losses: The 108 half cells reduce current in each cell string, which cuts resistive losses and supports higher efficiency. This layout also improves shade tolerance because the panel is effectively split, so partial shading has less impact on total power.

Thermal management and stability: The module operates around 45 ±2 degrees Celsius under standard test like conditions, with a Pmax temperature coefficient of minus 0.35 percent per degree. This controlled behaviour under heat helps maintain reliable output in warmer climates and during summer peaks.

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.
