Product Overview

The CiFi SUN 54HL4R-BDB 435W N-type TOPCon bifacial solar panel delivers high energy density in a compact footprint. This module is built around Jinko’s advanced N-type mono-crystalline cells, using HOT 2.0 TOPCon technology for strong performance. Its 435 W rated output and 21.77% efficiency help maximise yield on residential rooftops and small commercial arrays. Dual-glass bifacial construction allows energy capture from both front and rear surfaces in suitable installations. The panel operates reliably from −40 °C to +85 °C, making it suitable for diverse climates and harsh environments. A maximum system voltage of 1500 V and a 30 A series fuse rating support flexible string design for installers. With a 25-year product warranty and a 30-year linear power warranty down to 87.4% output, long-term value is protected. The all-black frame and dual-glass design also provide a clean aesthetic for projects where appearance matters.

Key Benefits

High power and efficiency: With 435 W output and 21.77% efficiency, this module delivers strong power density on limited roof space.

Advanced N-type TOPCon cells: N-type mono-crystalline cells with HOT 2.0 technology offer low degradation and excellent long-term performance.

Bifacial dual-glass design: The bifacial glass-glass structure enables additional energy yield from reflected light at the rear side.

Robust mechanical strength: Enhanced mechanical load ratings up to 5400 Pa front and 2400 Pa rear support challenging site conditions.

Long-term warranty protection: A 25-year product warranty and 30-year linear power warranty safeguard your investment over decades.

Flexible system integration: Compatibility with 1500 V systems and standard MC4-type connectors simplifies design and installation work.

How It Works

Sunlight hits the front surface of the 54HL4R-BDB module and is absorbed by N-type TOPCon cells. These high-performance mono-crystalline cells convert incoming photons into direct current electricity with strong efficiency. The bifacial design also collects reflected and diffuse light on the rear side when installed over bright or reflective surfaces. Direct current from the module flows through factory-fitted cables into a compatible string inverter or hybrid inverter. The inverter converts DC power into usable AC electricity for household loads or commercial equipment. Surplus energy can be exported to the grid or stored in batteries, depending on the system configuration used. Low temperature coefficients support better energy yield under hot operating conditions during summer days. Over decades, degradation remains low thanks to N-type cell chemistry and dual-glass encapsulation that resists moisture and stress.

N-type TOPCon cell conversion: N-type mono-crystalline cells use HOT 2.0 TOPCon passivation to reduce recombination losses. This results in higher conversion efficiency and slower power degradation over the module lifetime.

Bifacial dual-glass energy gain: The glass-glass structure exposes active cell surfaces on both sides. When mounted above bright ground or reflective rooftops, the rear side harvests additional light and boosts overall energy yield.

System integration and protection: Factory-installed MC4-compatible connectors and 4 mm² cables provide reliable DC connections. The IP68 junction box and Class II protection safeguard internal components against moisture, dust, and environmental stress.

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.

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

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!
