Sunage SAM 370 370W Monocrystalline Half-cut Solar Panel

Half-Cut Cells

Product Overview

The Sunage SAM 370 370W Monocrystalline Half-cut Solar Panel is designed for dependable residential and commercial solar power generation. It combines a high-efficiency monocrystalline cell structure with a half-cut layout that supports stable output and improved performance in real-world conditions. The module delivers 370 Wp of rated power and 20% efficiency, making it a practical choice for space-conscious installations. Its black finish, tempered glass front, and anodized aluminium frame create a durable, premium appearance. With a 12-year product warranty and a 25-year linear performance warranty, it is built for long-term energy production.

Key Benefits

Strong power output: Rated at 370 Wp, it supports reliable daily energy generation.

High module efficiency: The 20% efficiency rating helps maximize output from limited roof space.

Half-cut cell design: The 120-cell configuration helps reduce internal resistance and supports better shading tolerance.

Durable construction: Tempered glass, IP67 junction box protection, and an anodized aluminium frame improve long-term reliability.

Long warranty coverage: The panel includes a 12-year product warranty and a 25-year performance warranty for added confidence.

How It Works

This solar panel converts sunlight into direct current electricity through monocrystalline silicon cells. The half-cut design splits the cells into smaller sections, which reduces electrical resistance and helps maintain stronger performance under partial shading. The tempered glass front protects the module while allowing light to reach the cells efficiently. The IP67-rated junction box and MC4 connector system support safe field installation and dependable power delivery. The panel is engineered for stable operation across a wide temperature range, which helps preserve output in demanding outdoor environments. Its 1500V system rating also supports modern solar system designs.

Sunlight conversion: Monocrystalline cells absorb solar radiation and generate electrical current. This process creates usable DC power for your system.

Half-cut cell performance: Smaller cell segments lower resistance and improve electrical flow. This supports better output when conditions are not ideal.

Protected power delivery: The junction box, bypass diodes, and MC4 connector work together to move power safely. They also help reduce losses from shading and hot spots.

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.
