Product Overview

The Thornova TS-BG72(550) is a high-efficiency bifacial PERC solar module built with 144 half-cut monocrystalline cells and a durable dual-glass construction. Designed for strong real-world production, it combines a 550W rating with 21.3% module efficiency, helping maximize energy yield in residential, commercial, and utility-scale arrays. Its bifacial architecture can capture reflected light from the rear side of the module, improving output in suitable mounting environments.

With a silver 35mm aluminum frame, MC4-Evo2 connectors, and a 1500V DC system rating, this module is engineered for reliable installation and long-term outdoor performance. The TS-BG72(550) is also backed by a 15-year product warranty and a 30-year linear performance warranty, giving system owners confidence in both durability and sustained output.

Key Features

Massive 550W Output: High wattage helps reduce array size while maintaining strong total system capacity.

Bifacial Dual-Glass Design: Captures light from both sides of the module for additional energy generation, especially on reflective surfaces.

144 Half-Cut Cells: Half-cut cell architecture improves current handling, reduces resistive losses, and supports better shade tolerance.

Durable Outdoor Construction: The dual-glass structure, aluminum frame, and broad temperature range support dependable long-term operation.

Long Warranty Coverage: A 15-year product warranty and 30-year linear performance warranty help protect the investment over time.

How It Works

The TS-BG72(550) converts sunlight into DC power through its 144 half-cut monocrystalline cells. Because it is bifacial, the module can also generate additional energy from reflected light on the rear side, which can improve overall system output depending on mounting height and ground reflectance.

Bifacial Gain: Under favorable conditions, rear-side light capture can add up to 25–30% more energy production.

Module Protection: The tempered dual-glass construction and robust frame help the panel withstand demanding environmental conditions.

System Compatibility: MC4-Evo2 connectors and a 1500V DC rating make the module suitable for modern residential and commercial solar designs.

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!

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.
