Product Overview

The Upsolar UP-M390MH (60M6) 390W PERC monocrystalline solar panel is engineered for reliable, high efficiency energy production in residential and commercial systems. This module combines advanced PERC cell technology with a compact 120 half-cut cell layout to deliver strong performance even on limited roof space. With a panel efficiency of 21.41 percent, more power can be generated from each square meter, reducing balance of system costs. A maximum system voltage of 1500 volts supports modern string design and longer strings. The durable anodized aluminium frame and tempered glass with anti-reflection coating ensure long service life in challenging weather. Backed by Upsolar’s product and power warranties, this panel offers a dependable balance between performance, durability, and long term value.

Key Benefits

High power density for tight roofs: The 390 watt output and 21.41 percent efficiency help maximize energy on limited roof areas while keeping array size manageable.

Advanced PERC monocrystalline cells: PERC cell technology increases light capture and improves low light response, so more energy is produced across the day.

Low long term degradation: A total degradation rate of about 0.61 percent per year supports 93.05 percent output at year ten and 84.8 percent at year twenty five.

Robust mechanical design: Tempered glass, EVA encapsulant, and an anodized aluminium frame provide strength and stability under demanding environmental conditions.

Flexible system integration: A 1500 volt maximum system voltage and 20 amp series fuse rating support a wide range of modern inverters and string layouts in many project types.

How It Works

This Upsolar UP-M390MH solar panel converts sunlight into direct current electricity using high efficiency PERC monocrystalline cells. Each of the 120 half cut cells is wired into a carefully optimized string layout to balance current and voltage. When the panel is exposed to sunlight, photons strike the silicon lattice inside the cells and release electrons, creating an electrical current. The generated current flows through the internal busbars and bypass diodes in the junction box, then exits through the MC4 connectors. The DC power is routed to an inverter, where it is converted into usable AC electricity for homes, businesses, or export to the grid. Thermal characteristics and voltage behavior are carefully controlled by Upsolar so stable performance is maintained over a wide temperature range.

PERC monocrystalline energy conversion: The panel uses monocrystalline silicon cells with PERC technology to increase light absorption and reduce recombination losses. An additional passivated layer on the rear of each cell reflects unabsorbed light back into the silicon, capturing more energy from every ray. This design enhances output under direct sun and also improves production in hazy or low light conditions throughout the day.

Half cut cell layout and current flow: Each full cell is divided into two smaller cells, forming a 120 half cell matrix that reduces resistive losses. Lower current in each cell string decreases internal heating and improves module efficiency and reliability. Integrated bypass diodes help limit power loss in partial shading, as affected cell strings can be bypassed while the rest of the module keeps generating energy.

From DC output to AC power: Electrical energy produced by the cells is collected in the IP68 rated junction box and routed through 4 mm² DC cables with MC4 connectors. The output characteristics include a 35.2 volt voltage at maximum power and 11.08 amp current at maximum power under standard test conditions. When connected to a compatible inverter, this DC power is converted into AC electricity that can supply loads, charge batteries in hybrid systems, or feed the utility grid.

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.
