Product Overview

The SEG Solar SEG-570-BTA-BG 570W N-Type TOPCon bifacial solar panel delivers high power density for commercial and utility projects. This advanced module uses N-Type TOPCon monocrystalline cells, providing excellent efficiency and strong performance in real operating conditions. With up to 570 Wp front-side output and bifacial generation from the rear, more energy can be harvested from the same installation area. The panel efficiency reaches 22.07%, allowing optimized layouts on rooftops and ground mounts where space is valuable. A robust dual-glass construction and anodized aluminium frame support long-term reliability in challenging climates, including high wind and snow zones. A 15-year product warranty and 30-year power warranty with 87.4% end-of-term output give long lasting energy security for system owners.

Key Benefits

High power density for large arrays: Up to 570 Wp front-side output enables fewer modules per project and streamlined BOS costs.

Bifacial generation boosts yield: Rear-side production captures reflected light, increasing total kWh over the system lifetime.

Reliable N-Type TOPCon technology: N-Type TOPCon cells improve efficiency and limit degradation under heat and field conditions.

Strong long-term performance guarantees: A 15-year product warranty and 30-year power warranty support bankable project returns.

Engineered for harsh environments: Wide operating temperatures and robust glass help the module perform in extreme climates.

How It Works

This bifacial solar panel converts sunlight into electricity using advanced N-Type TOPCon monocrystalline cells. Light strikes the front glass and passes into the high efficiency cell matrix, where photons free electrons and create direct current. The bifacial design also enables the rear side to use reflected and diffuse light from the ground or nearby surfaces. Both faces contribute to higher energy yield, especially on bright surfaces such as concrete or light gravel. The generated current flows through super multi busbar conductors and is collected at the IP68 junction box. From there, DC power is routed to an inverter, which converts it into AC energy for site loads or export to the grid. Careful cell layout, temperature coefficients and low degradation rates help maintain stable power production across decades of operation.

Front-side energy conversion: High efficiency monocrystalline cells on the front face capture direct sunlight and diffuse sky radiation. The 570 Wp nominal power at STC helps arrays reach target capacities with fewer modules.

Rear-side bifacial gain: The rear glass layer allows additional light to reach the cell surfaces from behind the panel. This rear contribution can raise total energy output, improving LCOE on suitable mounting structures.

Thermal and electrical stability: Optimized temperature coefficients reduce performance losses in hot weather and maintain better summer production. The module then feeds stable DC power to the inverter, supporting consistent site performance.

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.

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.
