Shandong Green Sun GSPV-325W 325W Monocrystalline 72-Cell Solar Panel

Model GSPV-325W | Monocrystalline Silicon | 72 Full Cells | Monofacial | 1000V System Voltage

325 W
Max Power Output
320–335 Wp
Module Power Range
72 Cells
Monocrystalline Design

Product Overview

The Green Sun Solar GSPV-325W monocrystalline solar panel is engineered for reliable power production in residential, commercial, and off-grid systems. This 325 watt module uses high quality monocrystalline cells arranged in a 72 cell configuration to deliver stable output and long term performance. A durable anodized aluminium frame, EVA encapsulation, and TPT backsheet help protect the module in harsh outdoor environments. High transmittance tempered glass with anti reflection properties improves light capture and maximizes yield over the life of the panel. The GSPV-325W operates efficiently across a wide temperature range and is suitable for solar home systems, rooftop arrays, and ground mounted solar power plants. Designed and manufactured by Shandong Green Sun Trade Co., Ltd., it offers a strong balance of efficiency, robustness, and value for many project types.

Key Benefits

High efficiency monocrystalline cells: Premium monocrystalline silicon cells support strong power density and consistent energy generation over many years of operation.

Robust mechanical design: The double layer anodized aluminium alloy frame, EVA encapsulant, and TPT backsheet provide structural strength and long term durability in outdoor conditions.

Enhanced glass and weather resistance: High transmittance low iron tempered glass improves light transmission while resisting impact, wind loads up to 2400 Pa, and snow loads up to 5400 Pa.

Stable performance in varied climates: A wide operating temperature range from -40°C to 85°C and optimized temperature coefficients support reliable output in both hot and cold environments.

Proven long term warranties: Material and workmanship are covered for ten years, with stepped power warranties that help protect long term energy yield.

How It Works

The GSPV-325W solar panel converts sunlight into usable direct current electricity through high efficiency monocrystalline cells. Each of the 72 cells is formed from quality silicon material designed for stable electrical characteristics and long term reliability. When the panel is exposed to sunlight, photons strike the cell surface and generate an electric field that drives current through the internal circuit. This current is routed through the junction box and MC4 compatible connectors to your solar inverter, charge controller, or DC load. The module’s tempered glass, EVA encapsulation, and TPT backsheet protect the cells from moisture, dust, and mechanical stress so power production remains consistent over decades. The panel operates effectively under standard test conditions and continues to generate energy in high temperature, low irradiance, and cloudy weather situations.

Photovoltaic energy conversion: Sunlight hits the monocrystalline silicon cells and releases electrons inside the cell structure. An internal electric field created by the cell junction directs these electrons, producing direct current power at the module’s output terminals.

Module protection and durability layers: A 3.2 mm tempered glass front with anti reflection coating increases light transmission while shielding cells from impact and weather. EVA encapsulant and a TPT back cover seal the cells, reduce moisture ingress, and help maintain electrical insulation and safety over the system lifetime.

System integration and operation: The panel connects to the array wiring through MC4 connectors and 4 mm² solar cable. Its 1000 V DC maximum system voltage allows flexible string design with multiple modules in series, feeding inverters or charge controllers that convert the DC power into usable AC electricity or stored battery energy.

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.
