Mono Cells

Product Overview

The Sun Earth East Solar 400W panel is a monocrystalline module designed for dependable performance and strong energy yield. It combines a compact footprint with high power density, making it suitable for residential and commercial solar projects. The module offers 400W rated output, 20.5% efficiency, and a 108-cell layout for balanced performance. Its power tolerance of 0 to +1% supports consistent production. The panel is built with tempered glass, an anodized aluminium frame, and IP68 junction box protection. These features support long-term reliability in demanding outdoor conditions.

Key Benefits

High Power Output: Delivers 400W rated power for efficient energy generation.

Strong Efficiency: Provides 20.5% panel efficiency for better use of available roof space.

Reliable Degradation Profile: Maintains 83.3% output after 25 years and 81.0% after 30 years.

Durable Construction: Uses tempered glass, EVA encapsulant, and an anodized aluminium frame.

Weather Protection: Supports outdoor installation with IP68 junction box protection and wide temperature tolerance.

How It Works

This monocrystalline solar panel converts sunlight into usable electricity through high-efficiency photovoltaic cells. The 108-cell design helps deliver stable performance across a wide operating range. When sunlight reaches the module, the cells generate direct current for use in solar systems. The electrical output is supported by a low temperature coefficient, which helps reduce performance loss in hotter conditions. The panel is engineered for consistent operation in demanding environments. Its construction also supports reliable system integration through durable materials and sealed protection components.

Photovoltaic Conversion: Sunlight is captured by monocrystalline cells and converted into direct current electricity. This process supports efficient daily energy production.

Thermal Stability: The panel is designed to operate from -40 to 85 °C. The temperature coefficient helps preserve output as module temperature rises.

System Integration: Electrical values such as Vmpp, Voc, and Isc help match the module with compatible solar systems. The 1500V maximum system voltage supports modern installations.

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.
