Product Overview

The Green Sun Solar GSPV-320W monocrystalline solar panel delivers reliable 320 Wp output with a robust 72-cell layout. This high quality module is engineered for long term performance in residential, commercial, and off grid systems. High efficiency silicon cells are combined with low iron, anti reflection tempered glass to enhance light capture and power yield. A durable anodized aluminum frame and TPT backsheet help protect every cell from harsh outdoor environments. With a 10 year product warranty and long term power guarantee, the panel is designed to maintain strong output over decades. The GSPV-320W operates safely up to 1000 V system voltage, supporting flexible array configurations and scalable installations. Optimized electrical parameters and carefully matched components provide stable performance in high temperatures and low irradiance. This makes the Green Sun Solar GSPV-320W an excellent choice where dependable solar generation and good value are required.

Key Benefits

Reliable 320 Wp power class: Each module is rated at 320 Wp, supporting strong energy yields from a compact footprint. The carefully matched voltage and current values simplify string design in many systems.

High quality monocrystalline cells: Monocrystalline cells offer stable performance and strong efficiency across the 72 cell layout. This technology supports dependable energy production over many years of operation.

Durable glass and frame assembly: The 3.2 mm tempered glass with anti reflection coating improves light transmission and impact resistance. A double layer anodized aluminum alloy frame adds mechanical strength and stability during installation.

Stable output in harsh conditions: The panel is rated for operation from -40 °C to 85 °C, supporting many climates. Low temperature coefficients help limit power loss in high temperatures and sunny locations.

Easy integration and installation: Standard MC4 connectors and 4 mm² cables support quick connection to modern inverters. The 1956 x 992 x 40 mm dimensions and 23.5 kg weight allow straightforward handling on site.

How It Works

The Green Sun Solar GSPV-320W converts sunlight into usable DC electricity through its 72 monocrystalline cells. Each cell is manufactured from high purity silicon to create an efficient photovoltaic junction. When sunlight hits the tempered glass surface, the anti reflection coating helps transmit more light into the cells. This light energy frees electrons in the silicon structure and creates an electric current. The cells are wired in series and parallel within the module to reach 320 Wp at standard test conditions. Power is delivered through the integrated junction box, bypass diodes, and MC4 compatible connectors. Once connected to an appropriate solar inverter or charge controller, this DC power can support homes, businesses, or off grid systems. The robust construction allows the panel to operate safely over a wide temperature range and under challenging weather. With correct mounting and system design, the GSPV-320W will quietly generate clean energy for many years.

Monocrystalline energy conversion: Sunlight passes through the 3.2 mm low iron tempered glass onto the monocrystalline cells. These cells convert solar radiation into DC electrical energy through the photovoltaic effect.

Optimized electrical output: At maximum power, the module operates around 37.65 V and 8.5 A for a 320 Wp output. Bypass diodes in the IP rated junction box help limit losses during partial shading events.

System integration path: From the junction box, power flows through 4 mm² solar cables to MC4 connectors for safe mating. The DC output then feeds an inverter or controller, which converts it for on site loads or battery storage.

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.
