Product Overview

The Thornova NRJ-W120SS 400W HJT bifacial solar panel delivers high power density and excellent efficiency for modern systems. This advanced heterojunction module is ideal for residential, commercial, and light industrial rooftop arrays. Its bifacial design captures additional energy from the rear side, boosting overall yield on reflective surfaces. With module efficiency up to 22.0%, it helps achieve strong output even where roof space is limited. Engineered with 120 half-cut HJT cells, it offers lower electrical losses and enhanced reliability over time. The panel performs strongly in weak light and high temperature conditions thanks to a leading low temperature coefficient. A robust dual-glass construction, POE encapsulant, and anodised aluminum frame ensure long-term durability. Owners benefit from a 20-year product workmanship warranty plus a 30-year linear power warranty for dependable performance.

Key Benefits

High module efficiency up to 22%: Using high efficiency heterojunction cells, this module reaches up to 22.0% efficiency. This allows more power generation from limited roof or ground area.

Bifacial power gain for higher energy yield: Bifaciality above 90% boosts rear-side power, especially over bright or reflective surfaces. Systems can achieve significantly higher annual energy production.

Strong performance in heat and low light: A low power temperature coefficient of -0.26%/°C reduces losses in hot climates. Excellent weak light behavior keeps production stable on cloudy days and during mornings or evenings.

Durable dual-glass construction and high loads: The 2.0 mm front solar glass and rear ceramic patterned glass deliver mechanical strength. The module is certified to withstand 5400 Pa front loads and 2400 Pa rear loads for harsh conditions.

Extended 30-year power output warranty: Linear performance coverage guarantees only 1% loss in the first year. Annual degradation is limited to 0.37% until year 30, supporting long-term investment returns.

How It Works

This Thornova heterojunction bifacial solar panel converts sunlight into electricity using advanced 120 half-cut HJT cells. The front side captures direct solar radiation, while the rear side harvests reflected light from surrounding surfaces. Heterojunction technology combines crystalline silicon with thin amorphous layers for superior cell efficiency. Half-cut cell layout reduces internal resistance, which increases power and improves shade tolerance. When the module is exposed to sunlight, direct current flows through the integrated junction box and cables. This power is then sent to a compatible inverter, where it is converted into usable alternating current. The module is optimized for modern high voltage systems up to 1500V DC, enabling efficient string design. Advanced encapsulation and dual-glass construction protect the cells from moisture, temperature swings, and mechanical stress.

Heterojunction HJT cell structure: The module uses high efficiency heterojunction cells with crystalline silicon wafers. Thin amorphous layers on both sides reduce recombination and increase voltage. This structure supports higher energy yield, especially in warmer conditions.

Bifacial rear-side generation: Both glass sides are active, enabling power generation from front and rear. With bifaciality around 90%, reflected light is effectively captured by the rear cells. This design improves system performance on light colored roofs, concrete, snow, or reflective ground.

Half-cut cell and SuperMBB layout: Cells are cut into halves, which lowers current in each path and reduces resistive losses. A multi-busbar layout with 12 busbars enhances current collection across each cell. Together, these features support higher output and improved reliability over time.

Customer Success Stories

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.

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!
