Product Overview

The Sunage SAM 370 126 HALF CUT BACK CONTACT BLK is a high-performance monocrystalline solar panel built for modern residential and commercial systems. Its back contact design helps maximize active cell surface area and supports refined energy capture. The module delivers a rated output of 370 Wp and a strong efficiency of 20.60%. A full black appearance enhances visual appeal, while the 126 half-cell architecture supports balanced performance and reduced internal losses. This panel is designed for dependable long-term operation, with a 12-year product warranty and a 30-year linear performance warranty. It is an excellent choice for installations that value output, durability, and premium aesthetics.

Key Benefits

High Energy Output: The panel produces 370 Wp for reliable power generation.

Excellent Efficiency: A 20.60% module efficiency helps maximize available roof space.

Back Contact Design: The rear-contact architecture supports improved aesthetics and reduced front-side shading impact.

Long-Term Reliability: 12-year product coverage and 30-year performance support long service life.

Premium Build Quality: Tempered anti-reflection glass and anodized aluminium improve durability in demanding conditions.

How It Works

This module converts sunlight into electricity through high-quality monocrystalline cells arranged in a half-cut format. The back contact configuration keeps the front surface cleaner and more visually uniform. Electrical losses are reduced because the current path is optimized across the cell layout. That structure can also help maintain stable output under real-world operating conditions. The anti-reflection coated glass allows more sunlight to reach the cells. Combined with a robust frame and dependable junction box design, the panel is engineered for efficient and consistent solar generation over many years.

Back Contact Cell Layout: Electrical connections are positioned behind the cells. This creates a cleaner front surface and supports better light absorption.

Half-Cell Architecture: The 126 half-cell design helps lower resistance losses. It can also improve performance stability during partial shading conditions.

Durable Energy Conversion: Tempered glass, bypass diodes, and a strong frame protect the module. These features support safe operation and dependable output.

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.
