Product Overview

The SunMaster 595W PERC monocrystalline solar panel delivers high power density for modern residential and commercial arrays. This advanced module combines 595 watt peak output with a panel efficiency of 21.02 percent for excellent energy yield per square meter. Half-cell monocrystalline PERC cells and multi-busbar design enhance performance across varied light conditions and roof orientations. An optimized 120 half-cell layout with 210 by 105 millimeter cells supports reliable power delivery and reduced resistive losses. The durable anodized aluminum frame and 3.2 millimeter tempered glass with anti reflection coating provide long term mechanical strength. This SunMaster solar panel operates from minus 40 to plus 85 degrees Celsius, making it suitable for challenging climates worldwide. The module is engineered for system voltages up to 1500 volts, allowing flexible string design in large scale or rooftop projects. With robust temperature coefficients and excellent behavior at high temperatures, it maintains dependable output during hot summer days. Installers benefit from a well balanced combination of power, efficiency and manageable 31 kilogram weight for easier handling on site. Across the full 580 to 605 watt family, the SM12 series is built for reliable long term solar energy production.

Key Benefits

High power density for limited roof space: The 595 watt output and 21.02 percent efficiency help maximize energy generation where usable area is restricted.

Reliable performance in real world conditions: Low temperature coefficients and proven PERC cell technology maintain strong output in heat and low light.

Robust mechanical design and protection: Anodized aluminum frame, tempered glass and IP68 junction box support long service life in harsh environments.

Flexible system design options: Support for up to 1500 volt system voltage enables longer strings and efficient BOS cost optimization.

Bankable long term warranties: A 15 year material and technology warranty plus 30 year linear power output guarantee underpin investment confidence.

How It Works

This SunMaster 595W solar panel converts sunlight into usable direct current electricity through high efficiency monocrystalline PERC cells. Each 210 by 105 millimeter cell absorbs photons, creating charge carriers that move under the internal electric field. These carriers are collected by multi busbar conductors, which reduce resistance and improve overall module efficiency and reliability. The 120 half cell configuration minimizes internal losses and lowers operating temperatures across the active area of the panel. Generated direct current power is delivered through MC4 compatible connectors to the inverter or hybrid system components. The inverter then converts this direct current into grid compatible alternating current electricity for on site use or export. Carefully engineered temperature behavior helps stabilize power delivery during hot days and changing weather conditions. The module integrates seamlessly into residential, commercial or utility scale arrays designed around 1000 or 1500 volt strings. When combined with suitable mounting, monitoring and protective devices, the panel supports long term clean energy generation. System designers can use the detailed electrical characteristics at STC and NOCT to optimize array layout and performance.

High efficiency PERC monocrystalline cells: Passivated emitter and rear cell technology increases light capture and reduces recombination losses within the silicon. The result is higher conversion efficiency and improved yield under both strong and diffuse irradiance conditions.

120 half cell layout with multi busbar design: Half cut cells operate at lower current, which reduces resistive heating and enhances durability over time. Multi busbar wiring shortens current paths and offers better tolerance to minor micro cracks or shading.

Optimized performance across temperature and irradiance: The low Pmax temperature coefficient helps limit power losses as cell temperatures rise through the day. Performance data at STC and NOCT gives installers accurate expectations for output in different climates.

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.

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.
