Silfab SIL-430 QD 430W Monocrystalline Solar Panel

Model SIL-430 QD | N-Type Cell Technology | 108 Half-Cell | Monocrystalline | 1000V System Voltage

430 Wp

Max Power Output

22.1%

Module Efficiency

108

N-Type Half-Cells

Product Overview

The Silfab SIL-430 QD is a premium monocrystalline solar panel built for homeowners who want strong performance and refined aesthetics. It uses next-generation N-type cell technology to support improved low-light output, better shade tolerance, and reduced long-term degradation. With a 430 Wp power rating and 22.1% efficiency, it is well suited for roofs where space must be used efficiently. The black anodized frame and anti-reflection tempered glass create a sleek finish while supporting durability in demanding environments. Manufactured in the United States, this module is designed for dependable residential energy production.

Key Benefits

High Power Density: The 430 Wp output helps maximize energy production from limited roof space.

Excellent Efficiency: A 22.1% efficiency rating supports strong output from a compact module size.

N-Type Performance: Advanced N-type cell technology improves shade tolerance, low-light behavior, and long-term stability.

Long-Term Reliability: The panel is backed by a 25-year product warranty and a 30-year linear performance guarantee.

Durable Construction: Tempered glass, a black anodized aluminum frame, and an IP68 junction box support dependable operation.

Residential-Friendly Design: The all-black appearance creates a clean finish that blends well with modern rooftops.

How It Works

The Silfab SIL-430 QD converts sunlight into usable electricity through 108 N-type half-cells arranged to improve energy capture across different conditions. Light enters through anti-reflection tempered glass, which helps reduce surface glare and supports better transmission. The module produces direct current power, which is then routed through your solar inverter for use in the home. Its N-type design is engineered to limit degradation and maintain strong output over time. The panel is also built to handle wide temperature swings, making it suitable for varied climates and installation environments.

N-Type Cell Conversion: Sunlight is absorbed by 108 half-cells to generate direct current electricity. This architecture supports efficient power production in a compact format.

Low-Light and Shade Response: The module is designed to perform more consistently in challenging light conditions. This helps improve energy harvest during cloudy weather and partial shading.

Durable Power Delivery: The panel’s materials and temperature coefficients help maintain stable operation. Its reduced degradation profile supports better long-term output retention.

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.
