PERC Half-Cell

Product Overview

The Upsolar UP-M375MH 375W PERC monocrystalline solar panel is engineered for reliable high output in both residential and commercial systems. This advanced module delivers up to 375 watts of power with a module efficiency of 20.59 percent, making strong production possible even on tighter roofs. Half-cut 120 cell architecture helps reduce power loss and supports stable performance under real world operating conditions. A robust anodized aluminium frame, tempered glass, and EVA encapsulation are combined for long term durability. The panel sits within a broader 375 to 395 watt product range, so system designs can easily be optimized. With a 12 year product warranty and 25 year power warranty, this panel offers dependable solar generation backed by a trusted global manufacturer.

Key Benefits

High power density for limited roofs: A 375 watt output and over twenty percent efficiency allow strong energy yields from compact roof areas. This makes the panel suitable for small residential arrays and space constrained commercial projects.

Reliable long term performance: A total degradation rate of only zero point six one percent per year supports stable energy production. After ten years power is warranted at ninety three point zero five percent, and after twenty five years at eighty four point eight percent of initial output.

Robust construction for harsh climates: Anodized aluminium framing, three point two millimetre tempered glass, and EVA encapsulation are used. These materials help protect cells against mechanical stress, weather extremes, and moisture for dependable field operation.

Flexible system design: The panel supports maximum system voltages up to fifteen hundred volts and a series fuse rating of twenty amperes. This allows integration in modern string configurations with lower balance of system costs and efficient cabling layouts.

Easy installation and handling: A module weight of nineteen kilograms and dimensions of 1755 by 1038 by 30 millimetres support straightforward mounting. Standard MC4 connectors and four square millimetre cables simplify connections for installers and reduce onsite time.

How It Works

The Upsolar UP-M375MH solar panel converts sunlight into usable DC electricity through its PERC monocrystalline cells. Each of the 120 half cells is manufactured from high purity silicon, allowing efficient photon capture and charge carrier movement. When sunlight strikes the cell surface, electron hole pairs are generated and driven by the internal electric field to create current. That current is collected through the panel busbars and delivered through MC4 connectors into your DC wiring. The resulting energy can be routed into a compatible inverter, battery system, or hybrid solution. Thermal behavior is controlled through carefully selected temperature coefficients, ensuring predictable power output across a wide operating temperature range.

PERC monocrystalline cell conversion: Passivated emitter and rear contact technology increases light capture within each cell. Additional light reflected back into the silicon layer supports higher conversion efficiency and stronger output under standard test conditions.

Half-cut cell and string design: The 166 by 83 millimetre half cells reduce resistive losses compared with full size cells. Current is divided across more paths, which can lower internal heating and support better performance under partial shading scenarios.

System integration and protection: Three integrated bypass diodes in the IP68 junction box help limit power loss when parts of the module are shaded. MC4 connectors and four square millimetre cables transfer DC power safely into strings operating up to fifteen hundred volts.

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

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.
