N-Type HJT Cells

Product Overview

The Panasonic EVPV420HK2 solar panel delivers premium performance and durability for residential rooftops. This 420 watt HJT monofacial module combines high efficiency with compact dimensions to maximize energy yield on limited roof space. With module efficiency of 21.7 percent, more power is produced from every square meter of your array. Heterojunction N-type cells with gapless connections reduce electron losses and support strong output over the panel life. The EverVolt HK2 Black Series features a sleek all-black design that blends cleanly with modern homes. A low temperature coefficient of -0.24 percent per degree Celsius supports higher production on hot days. Homeowners can rely on a 25 year product and performance warranty with at least 92 percent power output guaranteed in year twenty five. Backed by Panasonic’s long history in solar, this module offers a reliable, future ready option for long term savings.

Key Benefits

High power density for tight roofs: The 420 watt rating and 21.7 percent efficiency enable strong output from a compact footprint, ideal for space constrained rooftops and complex layouts.

Reliable long term performance: An industry leading degradation profile supports at least 92 percent of initial power after 25 years, helping lock in predictable energy savings over the system life.

Optimized for hot climates: A low -0.24 percent per degree Celsius temperature coefficient limits output losses on hot roofs, which supports higher annual energy production in warm regions.

Advanced HJT N-type cell design: Heterojunction cells with gapless connections reduce recombination losses, provide low LID and PID, and support stable performance compared with conventional PERC modules.

Proven Panasonic quality and support: Over 40 years of solar experience and comprehensive EverVolt warranties cover product, performance, parts and labor for long term peace of mind.

How It Works

The Panasonic EVPV420HK2 converts sunlight into usable electricity using high efficiency N-type heterojunction cells. Each cell layers crystalline silicon with thin amorphous silicon films to reduce losses at the junction. When sunlight hits the cell surface, photons transfer energy to electrons, which then move through the internal electric field. This movement generates direct current power that flows through the panel’s busbars and wiring. Half cut cell architecture lowers resistive losses and improves shade tolerance across the module surface. The produced DC power is routed through MC4 connectors to string wiring and then delivered to a compatible inverter. The inverter converts the DC electricity into AC power for home loads or export to the grid. Throughout this process, the panel’s optimized temperature characteristics help maintain stable output in real world conditions.

Heterojunction cell architecture: HJT cells combine N-type crystalline silicon with amorphous layers to minimize electron recombination. This structure supports higher conversion efficiency, lower degradation and improved performance under varied temperatures and light levels.

Half cut layout and gapless connections: The module uses half cut cells wired in parallel strings to reduce current and resistive losses. Gapless connections expand the active area, enhancing light capture and boosting power output, especially when parts of the panel are lightly shaded.

System integration and energy delivery: Power leaves the panel through Stäubli MC4 connectors and 4 mm² PV wire, ensuring low loss transmission to the inverter. Once converted to AC, the energy can supply household circuits, charge batteries, or be exported to the grid under your utility’s interconnection rules.

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

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.

Brian H

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.
