Solenso NR--W120SS 400W HJT Bifacial Solar Panel

400 Wp
Max Power Output
22%
Module Efficiency
120
HJT Half-Cut Cells

Product Overview

The Solenso NR--W120SS is a high-efficiency monocrystalline bifacial solar panel built with advanced HJT technology. It delivers up to 400 Wp of power and reaches 22% module efficiency, making it a strong choice for modern solar installations. The 120-cell half-cut design supports improved energy generation and stable performance in demanding conditions. This module is designed for reliable long-term output, with strong mechanical durability and excellent hot-climate performance. Its slim 30 mm frame and 23.5 kg weight make handling and installation practical. The panel is suitable for residential and commercial projects that need consistent performance, strong durability, and space-efficient power generation.

Key Benefits

High Power Output: The module reaches 400 Wp, supporting strong energy production from a compact format.

Excellent Efficiency: With up to 22% efficiency, it converts more sunlight into usable electricity.

Bifacial Performance: Bifacial construction helps capture rear-side light and can improve total energy yield.

Hot Climate Stability: The low power temperature coefficient supports better performance in warm environments.

Strong Durability: The panel is engineered for snow loads up to 5400 Pa and wind loads up to 2400 Pa.

Reliable Warranty Coverage: It includes a 20-year product warranty and a 30-year performance warranty.

How It Works

This solar panel converts sunlight into electricity through advanced HJT cells and a half-cut cell layout. The heterojunction structure helps improve efficiency and supports strong output in both bright and weak-light conditions. Bifacial design allows the rear side to contribute extra generation when reflected light reaches the module. The panel is built to maintain stable performance across a wide temperature range. Its durable materials support long-term operation in residential, commercial, and utility-style systems.

HJT Cell Conversion: The heterojunction cell structure helps capture sunlight efficiently. It also supports better performance in hot weather and low-light conditions.

Half-Cut Cell Layout: The 120 half-cut cells reduce internal resistance and electrical loss. This helps improve output and supports more stable module performance.

Bifacial Energy Gain: The bifacial construction allows light from the rear side to contribute to power generation. That can increase total yield in reflective installation 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.

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.
