Thornova Solar TS-BW66(505) 505W HJT Bifacial Solar Panel

Model TS-BW66(505) | HJT Cell Technology | 120 Half-Cell | Bifacial | DC1500V System Voltage

505W
Max Power Output
22.00%
Module Efficiency
120
HJT Half-Cell

Product Overview

The Thornova Solar TS-BW66(505) is a high-efficiency bifacial solar panel built for strong, reliable energy production. It uses 120 HJT half-cut cells to improve output and support stable performance in challenging conditions. This module is designed for residential, commercial, and larger-scale solar projects that need dependable generation and long service life. Its bifacial construction helps capture additional light from the rear side, which can raise total system yield. With a 505W maximum power rating and up to 22% efficiency, it offers a strong balance of power density and installation flexibility. The panel also supports modern system designs with a 1500V maximum system voltage. Its durable construction and long warranty coverage make it a practical choice for performance-focused solar installations.

Key Benefits

High Power Output: The module delivers up to 505W for strong energy production in demanding systems.

Excellent Efficiency: Efficiency reaches 22.00%, helping maximize generation within limited roof or ground space.

Bifacial Gain: Bifaciality of 90±5% supports meaningful rear-side power generation in suitable installations.

Low-Light Performance: HJT cell technology provides strong output in weak light and hot climate conditions.

Durable Design: The panel is certified for 5400 Pa front load and 2400 Pa rear load resistance.

Long-Term Reliability: Anti-PID protection and low degradation support stable performance over many years.

How It Works

The Thornova Solar TS-BW66(505) converts sunlight into electricity through advanced heterojunction cell technology. Its HJT design combines crystalline silicon with thin-film layers to improve carrier collection and reduce energy loss. Half-cut cell architecture helps lower resistance and improve output consistency across the module. The bifacial rear side can capture reflected light, which increases total generation when installed above reflective surfaces. This design is especially useful for ground-mount, carport, and open-frame systems. The module also supports stable operation in hot weather, because its temperature coefficient is low. That helps preserve power output when module temperatures rise during daily operation.

HJT Cell Conversion: The heterojunction cell structure improves light-to-electricity conversion efficiency. It also supports better performance in low-irradiance conditions.

Half-Cut Current Control: Half-cut cells reduce electrical resistance and help minimize internal power loss. This improves output stability across the panel surface.

Bifacial Rear-Side Capture: The rear glass design allows additional light to be converted from reflected irradiation. That can improve total system yield in the right installation environment.

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

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.
