SEG Solar SEG-580-BTA-BG 570–585W Bifacial TOPCon Solar Panel

Model SEG-580-BTA-BG | Bifacial TOPCon | 144 Half-Cell | Bifacial | 1500V System Voltage

580 Wp

Max Power Output

22.45%

Module Efficiency

144

N-Type TOPCon

Product Overview

The SEG Solar SEG-580-BTA-BG is a high-output bifacial solar panel built with N-Type TOPCon technology. It is designed for strong performance, reliable energy generation, and excellent long-term value. This 580 Wp module belongs to the YUKON N Series and delivers a module efficiency of 22.45%. Its bifacial design helps capture additional energy from reflected light, which can improve overall yield in suitable installations. The panel also features a 15-year product warranty and a 30-year power warranty, supporting confidence in long-term operation. With a 144 half-cell layout, 1500V system voltage, and durable construction, it is suited for commercial and utility-scale solar projects.

Key Benefits

High Power Output: The module delivers up to 580 Wp for strong energy production.

Bifacial Gain Potential: Rear-side generation can add more output in reflective environments.

TOPCon Efficiency: N-Type TOPCon cells support excellent efficiency and stable performance.

Long Warranty Coverage: A 15-year product warranty and 30-year power warranty add peace of mind.

Durable Build Quality: Anti-reflection glass and an anodized aluminium frame support reliability.

Utility-Friendly Design: The 1500V system rating suits larger solar installations.

How It Works

This module converts sunlight into electricity through advanced N-Type TOPCon cells. The 144 half-cell structure helps reduce resistive losses and supports dependable output. Its bifacial design captures light from the front and rear sides, which can increase total energy harvest when installed above reflective surfaces. Anti-reflection glass helps reduce light loss at the surface. The panel is engineered for demanding operating conditions, including high system voltage applications and a wide temperature range. Together, these features support consistent generation across commercial and utility-scale sites.

Front-Side Generation: Sunlight passes through the anti-reflection glass and is converted by the front cells. This creates the main power output under standard conditions.

Rear-Side Bifacial Capture: Light reflected from the ground can also be absorbed. This adds extra generation in suitable mounting setups.

Half-Cell Performance: The half-cell layout helps reduce internal resistance and shading losses. That supports better electrical stability during operation.

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.
