ABi-Solar AB665-66MHC 665W PERC Monocrystalline Solar Panel

Model AB665-66MHC | PERC | 132 Half-Cells | Monocrystalline | 1500V System Voltage

665W

Max Power Output

21.41%

Module Efficiency

132

PERC Cells

Product Overview

The ABi-Solar AB665-66MHC delivers 665W monocrystalline solar panel performance for commercial projects. This PERC technology panel achieves 21.41% efficiency. It features 132 half-cut cells for optimal energy harvest. Built by ABi-Solar Inc in the United States, reliability is ensured. Power output remains strong over decades. Dimensions measure 2384x1303x35 mm. Weight is 33.9 kg for easy handling. Tempered glass protects against weather. Anodized aluminum frame adds durability. This panel suits large-scale solar installations perfectly.

Key Benefits

High Efficiency: 21.41% module efficiency maximizes energy production per square foot.

Superior Warranty: 15-year product and 25-year power output warranties provide peace of mind.

Half-Cut Cell Design: Reduces mismatch losses and improves shading tolerance significantly.

Load Resistance: Handles 5400 Pa snow and 2400 Pa wind loads with ease.

Low Degradation: Annual degradation rate stays below 0.61% for long-term performance.

How It Works

PERC monocrystalline cells capture sunlight efficiently. Half-cut design minimizes losses from shading. Shorter ribbons reduce internal resistance. Bypass diodes protect strings during partial shade. The panel converts sunlight to DC power reliably. Temperature coefficients ensure stable output in varying conditions. IP68 junction box safeguards connections. This technology delivers consistent energy for grid-tied systems. Aluminum frame and tempered glass withstand harsh environments. Multi-busbar design lowers resistance further. Overall, superior engineering maximizes lifetime yield.

PERC Cell Technology: Passivated rear enhances light absorption. Electrons flow more freely to front contacts. Efficiency reaches 21.41% as a result.

Half-Cut Cells: Each cell splits into two independent halves. Shading affects only part of the panel. Power output stays higher during clouds.

Dual Strings Design: Two parallel strings reduce mismatch losses. Current flows optimally through unshaded areas. Yield increases by up to 50%.

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.
