First Choice Solar FSC 390W Full Black MWT Monocrystalline Solar Panel

MWT Monocrystalline

Product Overview

The First Choice Solar FSC 390W Full Black MWT monocrystalline solar panel combines elegant design with reliable performance for modern rooftops. This high efficiency 390 Wp module uses advanced metal wrap through cell technology to deliver strong output in a compact footprint. Its full black appearance suits residential and commercial projects where aesthetics matter as much as yield. With a module efficiency of 20.9 percent, more energy is produced from limited roof space. The panel is engineered for 1500 volt systems, giving designers flexibility in string configuration and system layout. A robust 25 year product warranty supports long term reliability and peace of mind. The 30 year power warranty limits degradation to 85.45 percent of initial output, helping to secure predictable lifetime energy production. Durable tempered glass with anti reflection coating and an anodized black aluminium frame protect the cells in harsh climates. The FSC 390W Full Black MWT panel is assembled for easy integration using MC4 connectors and 4 mm² cables. It is an excellent choice for customers seeking premium looks, long warranties, and stable performance over decades. Each panel weighs only 20 kilograms, making handling and installation straightforward for installers. Designed in the Netherlands and supplied by First Choice Solar BV, it supports demanding European quality expectations.

Key Benefits

High power density: The 390 Wp output and 20.9 percent efficiency deliver more energy per square meter, ideal for roofs with limited space.

Sleek full black design: The full black cells, frame, and back side provide a uniform appearance that blends with dark roof coverings.

Long term reliability: A 25 year product warranty and 30 year power warranty with 85.45 percent end performance support long term system value.

Robust thermal performance: Optimised temperature coefficients help maintain output in hot conditions, reducing seasonal performance losses.

Installer friendly construction: The 20 kilogram weight, MC4 connectors, and 1100 millimetre cables make transport and installation efficient for professional crews.

High system voltage compatibility: Support for 1500 volt systems allows longer strings, fewer combiner boxes, and potential balance of system savings.

How It Works

This monocrystalline MWT solar panel converts sunlight into direct current electricity through high quality silicon cells. Each of the 126 cells uses metal wrap through contacts that route current through the rear, reducing shading on the cell surface. This design increases active area and improves module efficiency without enlarging the panel footprint. During operation, light strikes the anti reflective tempered glass and passes efficiently into the cell layer. The cells generate current which is collected and combined into the panel’s positive and negative output leads. When connected into an array, the modules feed a solar inverter that converts the direct current into usable alternating current power. The 1500 volt system rating enables longer strings of modules, simplifying wiring in large residential and commercial systems. Stable performance is maintained over a wide operating temperature range from minus 40 to plus 85 degrees Celsius. Protective materials and a sealed junction box shield the electrical components from moisture and dust. Once installed, the FSC 390W Full Black MWT panel delivers quiet, low maintenance solar energy for many years.

Monocrystalline MWT cell conversion: Sunlight is absorbed by high purity monocrystalline cells that use metal wrap through contacts to carry current on the rear side. This layout frees more front surface for light absorption and increases overall energy yield compared to conventional front contact designs.

Energy collection and DC output: Individual cells are interconnected to achieve a maximum power of 390 Wp at 36.1 volts and 10.81 amps under standard conditions. The resulting direct current leaves the panel through MC4 connectors and 4 mm² cables, ready for connection to string wiring and inverters.

System integration and protection: The IP68 junction box safeguards internal connections against water and dust for reliable outdoor use. The module supports systems up to 1500 volts, enabling efficient array design with longer strings and reduced cabling components.

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.
