Apex Service 605–625W N-Type TOPCon Monofacial Solar Panel

Model Apex Service | N-Type TOPCon | 144 Half-Cell | Monofacial | 1500V System Voltage

625 W
Max Power Output
22.36%
Module Efficiency
N-Type
N-Type TOPCon

Product Overview

This high output N-Type TOPCon solar panel range delivers between 605 and 625 watts of reliable power. The advanced tunnel oxide passivated contact architecture is used to raise efficiency up to 22.36 percent. Each module is engineered for projects where every square meter of roof or ground space matters. The panel suits commercial rooftops, ground mount systems, and demanding industrial arrays. A robust 34.6 kilogram frame helps ensure mechanical stability under wind and snow loads. Power is produced efficiently even when light conditions change during the day. The module uses proven crystalline silicon cell technology that supports low degradation operation. System designers can confidently integrate these modules into 1500 volt DC arrays. Performance remains stable over time due to the n-type cell platform and optimized contacts. This range offers a practical balance between high output, proven technology, and long term value.

Key Benefits

High power density for large projects: Each module delivers up to 625 watts from a single panel. This allows higher system power with fewer modules and faster installations.

Advanced N-Type TOPCon efficiency: The tunnel oxide passivated contact design improves carrier collection. This supports module efficiencies between 21.64 and 22.36 percent.

Improved energy yield in real conditions: The n-type structure reduces light induced degradation over time. Stable performance is maintained during early morning, late evening, and cloudy periods.

Robust and installation ready design: The 34.6 kilogram construction supports reliable mounting in challenging climates. Modules can be used on commercial rooftops or ground structures with confidence.

Flexible use across system sizes: The power range from 605 to 625 watts suits many layouts. Designers can match string lengths and inverters efficiently for different project scales.

How It Works

Sunlight strikes the front surface of each N-Type TOPCon cell and generates electron hole pairs. Because the silicon base is n-type, fewer impurities are present and carrier lifetime is higher. An ultra thin tunnel oxide layer is positioned between the wafer and the rear contact structure. This layer helps passivate the surface and reduces recombination losses at the rear interface. A doped polysilicon layer is then used to create a passivated contact region. This region allows electrons to tunnel through the oxide and reach the metal contacts efficiently. The improved contact structure raises the open circuit voltage and overall module efficiency. All cells are connected in series to build string voltage within the panel frame. The finished module then feeds direct current power to inverters through standard cabling. System designers can combine multiple modules in strings to match inverter input windows. Energy is converted to usable alternating current while high panel performance is maintained.

N-Type silicon base and carrier lifetime: The cells use phosphorus doped n-type silicon wafers with low impurity levels. This material choice supports longer carrier lifetime and lower degradation during long term use.

Tunnel oxide passivated rear contact: A nanoscale oxide layer is formed at the rear of the cell to passivate the surface. Electrons tunnel through this layer into a doped polysilicon contact that reduces recombination losses.

Module level power conversion: All TOPCon cells are wired in series to reach the required operating voltage. The module output connects to inverters, which turn the direct current into clean grid compatible power.

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

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.
