CiFi SUN 54HL4R-BDB 450W N-Type TOPCon Bifacial Solar Panel

450 Wp
Max Power Output
22.52%
Module Efficiency
108
N-Type TOPCon

Product Overview

The CiFi SUN 54HL4R-BDB 450W solar panel is built for dependable residential and commercial energy generation. It uses N-type TOPCon bifacial technology to deliver strong output and excellent long-term performance. With a 450Wp rating, this module supports efficient system design in limited roof space. Its all-black dual-glass construction improves durability and helps maintain a premium appearance. The panel also offers a 25-year product warranty and a 30-year power warranty, which supports long service life and reliable energy production. Designed with 108 half-cells, it provides stable operation, reduced resistance loss, and strong performance in real-world conditions.

Key Benefits

High Power Output: The 450Wp rating supports strong energy generation for demanding solar projects.

Excellent Efficiency: Up to 22.52% efficiency helps maximize yield from available installation space.

Bifacial Generation: Rear-side light capture can increase total energy production in suitable environments.

N-Type Reliability: N-type cells help reduce degradation and improve long-term performance stability.

Durable Dual-Glass Build: The glass-glass structure offers added protection and improved mechanical strength.

Strong Warranty Coverage: A 25-year product warranty and 30-year power warranty support long-term confidence.

How It Works

This bifacial TOPCon solar panel converts sunlight into electricity through advanced n-type monocrystalline cells. The front side captures direct sunlight, while the rear side can absorb reflected light from surrounding surfaces. This dual-sided generation helps improve overall system output in the right installation conditions. The half-cell format also reduces electrical resistance and supports better performance under partial shading. As a result, the module is well suited for installations that need efficient power production and dependable long-term operation.

N-Type TOPCon Cell Technology: These cells are engineered for high efficiency and lower degradation. They support strong performance over many years.

Bifacial Power Generation: Light entering the rear side can also be converted into electricity. This can improve yield when the installation surface reflects sunlight.

Half-Cell Module Design: The 108 half-cell layout helps reduce power loss and improves thermal behavior. It contributes to stable output in changing weather.

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.
