Product Overview

The Tongwei TWMNH-48HD465W 465W N-type bifacial dual glass solar panel is engineered for premium residential and light commercial use. This compact, lightweight module delivers high power density, making it ideal for carports, balcony systems, and space constrained rooftops. Advanced N-type half cells and bifacial technology unlock additional energy yield from reflected light behind the module. A maximum efficiency of up to 23.3% is achieved at the front side under standard test conditions. Durable dual glass construction and a black anodized frame provide strong mechanical stability and a clean architectural appearance. The panel supports system voltages up to 1500V, enabling flexible string design and lower balance of system costs. Thanks to low annual degradation and a long linear power warranty, reliable output is maintained for decades. This module is designed for customers who want long term energy savings with modern aesthetics and robust performance. It integrates easily with mainstream string and hybrid inverters, making project design straightforward and cost effective.

Key Benefits

High power in a compact footprint: Each module delivers up to 465 watts while keeping dimensions manageable. This allows powerful arrays even where roof or mounting space is limited, increasing design flexibility.

Bifacial energy gain: The dual glass bifacial design captures light on both sides of the panel. Rear side gains can significantly boost total energy yield on reflective surfaces such as light concrete, metal decks, or carport roofs.

Superior N-type reliability: N-type cells resist common degradation effects seen in conventional P-type modules. This improves long term performance stability and supports the 30 year linear power warranty offered by Tongwei.

Robust dual glass construction: Semi tempered glass on both sides increases mechanical strength and weather resistance. The module is designed to withstand high snow loads and wind pressures in demanding environments.

Elegant black frame aesthetics: The black anodized frame and transparent rear glass give a refined architectural finish. This makes the panel particularly attractive for visible installations on balconies, carports, and premium rooftops.

Optimised for modern 1500V systems: With a maximum system voltage of 1500V DC, longer strings can be used. This reduces cabling, combiners, and installation time, helping to lower total project costs.

How It Works

The TWMNH-48HD465W panel converts sunlight into usable electricity through advanced N-type bifacial solar cells. When sunlight reaches the front glass, photons are absorbed by the N-type cells and generate a flow of electrons. These electrons move through the cell circuitry and create direct current power at the module terminals. Because the panel is bifacial, additional light hitting the rear glass is also utilized. Reflected and diffuse light behind the module can produce extra current, increasing total energy output over the year. The half cell layout reduces resistive losses and improves shade tolerance across the module surface. Generated DC power is then routed through the integrated junction box and cables to a compatible inverter. The inverter converts the DC energy into AC power that can be used on site or exported to the grid. Throughout operation, temperature coefficients and low degradation characteristics help keep performance stable. This combination of cell technology, optical design, and robust construction ensures dependable energy production in real conditions.

Front side energy conversion: Sunlight passes through the anti reflection coated front glass and reaches the N-type cells. Electrons released in the silicon lattice are directed by conductors, creating current at the module output.

Rear side bifacial gain: Light reflected from surfaces under and around the panel enters through the transparent rear glass. This rear side illumination adds extra current generation, particularly on bright or reflective mounting surfaces.

System integration and output: The module’s MC4 compatible leads connect to series strings within the array. Inverters convert the combined DC output to AC, while the linear power warranty ensures dependable yield is maintained over the system lifetime.

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.
