Product Overview

The Tongwei Solar TWMNH-48HD455W bifacial dual glass module delivers high performance in a compact footprint. This N-type half-cell panel offers a powerful 455W output with up to 22.8% front-side efficiency. Power is captured from both sides of the module, which boosts real-world yield on reflective surfaces. Its dual glass construction enhances durability and long-term reliability in harsh outdoor conditions. The module size remains installation friendly at 1762 x 1134 mm with a low 30 mm depth. Weight is only 23.7 kg, so handling on rooftops and carports stays manageable. With a 1500V system rating, the panel suits modern residential, commercial and light industrial arrays. A black anodized frame and transparent back glass offer clean aesthetics for carport and balcony projects. The linear power warranty supports long-term energy planning with 87.4% output guaranteed at year 30. This combination makes the TWMNH-48HD455W ideal where efficiency, design and longevity are required.

Key Benefits

High power density in compact size: An output of 455W with 22.8% efficiency maximizes energy from limited roof or carport space.

Bifacial N-type technology for higher yield: Rear-side generation captures reflected light, lifting total kWh production over the system life.

Durable dual glass construction: Semi tempered glass on both sides improves fire resistance, weatherability and long-term mechanical strength.

Low degradation and strong warranty: Year one power is guaranteed at 99%, with only 0.4% annual degradation and 87.4% output at year 30.

Versatile applications and sleek design: The black frame and transparent rear glass work perfectly on carports, balconies and modern rooftops.

System-friendly electrical design: A 1500V maximum system voltage and 30A fuse rating support longer strings and reduced BOS costs.

How It Works

Sunlight hits the front glass of the Tongwei TWMNH-48HD455W panel and passes into the N-type monocrystalline cells. Each half-cell converts photons into direct current using high efficiency HJT and TOPCon style junctions. Because the module is bifacial, the rear glass also accepts reflected and diffuse light from below the array. This rear-side light is converted into additional power, which increases the effective energy yield over time. The 96 half-cell layout balances voltage and current to keep losses low in real operating conditions. Generated DC power flows through the three-diode junction box and out via 4 mm² solar cables. The DC is then routed to a compatible string or hybrid inverter, where it is converted into AC power. This AC energy is used onsite for home or business loads or exported back to the grid if allowed. Optimized temperature coefficients keep power output more stable during hot summer conditions. Together these elements create a reliable module that turns available light into dependable clean electricity.

Front-side generation: High-transmittance AR coated front glass directs more light into the N-type cells. The 22.8% efficiency means more of that light becomes usable DC power even in constrained spaces.

Rear-side bifacial gain: The transparent rear glass allows light from reflective surfaces to reach the cell rear. Bifaciality around 80% means notable extra output on bright ground or white carport roofs.

Stable performance in real conditions: Low temperature coefficients reduce power loss as cell temperature rises. Combined with robust dual glass encapsulation, the module maintains performance for decades in demanding climates.

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. 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.
