Thornova Solar TS-BW66(510) 510W HJT Bifacial Solar Panel

HJT Bifacial

Product Overview

The Thornova Solar TS-BW66(510) is a high-performance bifacial solar panel built with HJT cell technology. It is designed for strong energy production in residential, commercial, and utility applications. The module delivers up to 510W of rated power and reaches 22.0% efficiency. Its advanced half-cut design supports better output under real-world conditions. Bifacial generation helps capture more energy from reflected light. Strong mechanical ratings and long warranty coverage add further value for demanding installations.

Key Benefits

High Output Rating: Delivers up to 510W for strong system-level energy production.

Excellent Efficiency: Reaches 22.0% module efficiency for better space utilization.

Bifacial Power Gain: Bifaciality of 90±5% improves backside energy generation.

Strong Mechanical Strength: Certified for 5400 Pa front load and 2400 Pa rear load.

Long-Term Reliability: Features low degradation, anti-PID resistance, and a 30-year performance warranty.

Better Low-Light Performance: HJT technology supports excellent output in weak light and hot climates.

How It Works

The TS-BW66(510) works by combining HJT cell architecture with bifacial design. This allows the module to convert sunlight from the front and rear sides. Half-cut construction helps reduce internal resistance and improves power stability. The 12BB design supports better current collection across the cell surface. Together, these features improve energy harvest across changing weather, roof angles, and ground reflections. The module is also designed to keep performance more stable in high temperatures. That makes it suitable for projects that need dependable output over many years.

HJT Cell Conversion: Heterojunction cells help the module capture sunlight efficiently. They also support strong performance in weak light and heat.

Half-Cut Cell Layout: The half-cut format lowers resistance and supports smoother current flow. It can also improve shading tolerance in practical installations.

Bifacial Energy Capture: Rear-side generation adds usable power from reflected light. This boosts output in suitable mounting environments.

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.
