N-Type TOPCon

Product Overview

The CiFi SUN 54HL4R-BDB 425W solar panel is built for strong performance, long-term durability, and modern rooftop appeal. It uses bifacial, N-type TOPCon technology to support higher energy harvest and dependable output in demanding conditions. With 108 half-cells, the module helps reduce electrical losses and improves performance stability. Its all-black finish and dual-glass construction give it a premium look while supporting reliable operation over time. This panel is well suited for residential and commercial installations that need efficient power generation, durable materials, and a clean aesthetic. The 425W rating and 21.27% efficiency make it a practical choice for high-quality solar projects.

Key Benefits

High Power Output: Delivers 425W at STC, supporting strong energy production for modern solar systems.

Bifacial Energy Gain: Captures light from both sides, helping increase total generation when rear-side exposure is available.

N-Type TOPCon Efficiency: Advanced cell technology improves efficiency and supports better low-light performance.

Durable Dual Glass Design: Front and back glass layers enhance strength and support long service life.

Sleek All-Black Appearance: The black frame and premium finish create a refined look for visible rooftop installations.

How It Works

This module converts sunlight into direct current electricity through N-type monocrystalline cells. The TOPCon structure helps reduce recombination losses, which supports higher efficiency and better long-term performance. Its bifacial design allows the rear side to capture reflected light, especially on bright surfaces. That added input can improve total system yield without increasing panel footprint. The 108 half-cell layout lowers internal resistance and helps maintain stable output under partial shading or uneven light conditions. Dual-glass construction adds mechanical strength and helps protect the cells from environmental stress. Together, these features create a module designed for reliable generation, solid durability, and efficient use of available sunlight.

N-Type TOPCon Cell Conversion: Sunlight is converted using advanced N-type cells. This helps support higher efficiency and lower power loss.

Bifacial Rear-Side Generation: Light reaching the rear side contributes additional power. This can improve output in reflective or open installations.

Half-Cell Electrical Layout: The 108 half-cell design reduces resistance and helps the panel perform more consistently. It also supports better shade tolerance.

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

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.
