Product Overview

The SEG Solar SEG-470-BTB-BG N-Type TOPCon bifacial solar panel delivers 470 watts of high-efficiency power for residential, commercial, and utility projects. This premium module pairs advanced N-type TOPCon cell technology with a bifacial design to capture sunlight from both sides of the panel for increased energy yield. With a module efficiency up to 22.17%, this panel helps maximize power density where roof or ground space is limited and long term output matters. Its monocrystalline half-cell layout improves reliability and reduces resistive losses for stable performance in real-world conditions. The double-glass construction, robust frame, and IP68-rated junction box ensure dependable operation in harsh climates with wind, snow, sand, and salt exposure. Backed by a 15-year product warranty and a 30-year linear power warranty, the SEG-470-BTB-BG offers a dependable long term energy solution with minimal degradation over time.

Key Benefits

High power density for limited space: The 470 W output and up to 22.17% efficiency allow more energy production from smaller roofs or arrays. This makes the panel ideal where project space is constrained but energy targets remain ambitious.

Advanced N-type TOPCon technology: N-type TOPCon cells deliver lower degradation, better low light response, and improved performance at high temperatures. This helps maintain strong production throughout hot summers and across the full service life.

Bifacial design for higher energy yield: The bifacial glass-glass structure converts light hitting the rear side into additional power. When installed over reflective surfaces, energy yield can increase significantly compared to monofacial modules.

Durable double-glass construction: Front and back 2.0 mm semi-tempered glass provide excellent mechanical strength and environmental protection. The module withstands high snow and wind loads, supporting long term reliability in demanding sites.

Long-term warranty confidence: A 15-year product warranty and 30-year linear performance warranty with only 0.42% annual degradation secure long-term investment value. System owners benefit from predictable output and reduced lifetime energy costs.

How It Works

The SEG Solar SEG-470-BTB-BG solar panel works by converting sunlight into direct current electricity through high efficiency N-type TOPCon monocrystalline cells. Each half-cut cell generates power when photons strike the silicon and release electrons, creating an electric current across the cell surface. These cells are interconnected into a 120 half-cell layout that reduces resistive losses and improves shade tolerance under partial obstruction. The bifacial glass-glass design captures light on both the front and rear sides, increasing total energy yield over reflective surfaces like white roofs, concrete, or light gravel. Produced current flows through the integrated MC4-compatible connectors to the DC cabling and onward to the inverter, where it is converted into AC electricity usable by homes, businesses, or the grid. Integrated bypass diodes inside the IP68 junction box help protect the string during shading or mismatch events, maintaining stable system performance. The module is engineered to operate between -40°C and 85°C, with optimized temperature coefficients that limit power loss on very hot days. Over time, a controlled degradation rate and robust materials ensure that energy production stays strong across the full thirty-year warranty period.

N-Type TOPCon cell conversion: Sunlight strikes the N-type TOPCon monocrystalline cells and frees electrons within the silicon structure. The cell design reduces recombination losses, so more of the captured light becomes usable electric current with higher efficiency and lower degradation.

Bifacial double-glass energy capture: The front glass receives direct sunlight while the rear glass collects reflected and diffused light from the ground or nearby surfaces. Both sides feed power into the same circuit, which increases total kilowatt-hour yield compared with similar monofacial designs.

System integration and protection: Current from the cells travels through three bypass diodes in the IP68 junction box, which protect against hot-spots in shaded sections. The 1500 V system voltage rating and 30 A series fuse rating support integration into modern high-voltage arrays with long DC strings.

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.
