Dual-Sided Power

Product Overview

The REC Alpha Pure series represents a major advance in solar technology, offering exceptional power efficiency and an environmentally friendly design. The REC400AA model features 80 half-cut heterojunction bifacial cells with gapless cell layout, achieving 20.7% module efficiency with a lead-free design that aligns with global sustainability standards. Advanced anti-reflective glass enhances light absorption while the IP68-rated junction box ensures reliable long-term operation. Built with robust anodized aluminum framing and high-resilience polymers to withstand harsh weather conditions. Made in Singapore with sustainable production practices.

Key Features

High-Efficiency Heterojunction Cells: 80 half-cut REC bifacial heterojunction cells deliver superior conversion rates, ensuring more sunlight is transformed into usable energy.

Lead-Free Design: Designed without lead, aligning with global sustainability standards while providing safe, clean energy that contributes to a healthier planet.

Gapless Cell Layout: Innovative design maximizes power output by allowing more solar cells per module, enhancing efficiency and ensuring higher energy yields in limited space.

Bifacial Technology: Captures sunlight on both sides of the panel, boosting overall performance and power production efficiency with dual-sided energy generation.

Anti-Reflective Glass: Enhanced light absorption treatment reduces energy losses and maximizes the panel's overall efficiency under various lighting conditions.

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.
