Product Overview

The Green Sun Solar GSPV-310W 156M-66 monocrystalline solar panel delivers reliable 310 watt performance for residential and commercial arrays. This high quality module uses 66 monocrystalline cells sized 156 x 156 mm for stable power generation and consistent long term output. A robust double-layer anodized aluminum frame supports the panel and protects it in demanding on-grid or off-grid installations. Durable 3.2 mm tempered glass and TPT backsheet help resist impact, moisture, and environmental stress over many years. The GSPV-310W solar panel is engineered for 1000V DC systems, giving designers flexibility across small rooftops and larger projects. It offers a practical balance of output, footprint, and cost for installers seeking dependable monocrystalline technology. With factory assembled MC4 compatible connectors and 900 mm cables, integration into standard PV systems is straightforward. This solar panel suits homes, small businesses, agricultural systems, and project developers who want dependable power from a proven design.

Key Benefits

Dependable 310W power class: Each module delivers up to 310 watts of power, supporting efficient system designs and strong energy yields.

Proven monocrystalline cell technology: High quality monocrystalline solar cells provide stable performance, attractive appearance, and solid energy density on rooftops.

Rugged construction for harsh sites: The tempered glass, TPT backsheet, and anodized aluminum frame help the panel withstand wind loads up to 2400 Pa and snow loads up to 5400 Pa.

Flexible system compatibility: A maximum system voltage of 1000V DC and MC4 compatible connectors support a wide range of residential and commercial inverters.

Long term performance assurance: A linear power output warranty over 25 years supports long term investment planning and projected energy production.

How It Works

This Green Sun Solar GSPV-310W monocrystalline panel converts sunlight into usable DC electricity through high efficiency silicon cells. Each of the 66 cells generates voltage when exposed to light and they are connected in series and parallel strings inside the module. The panel operates at a nominal voltage of 34.32 V and a nominal current of 9.03 A at standard test conditions. Generated DC power flows through the integrated junction box and MC4 compatible connectors into the rest of the solar array. From there, an inverter converts DC power into AC electricity suitable for home or business loads. The sturdy frame, EVA encapsulation, and protective glass help maintain cell alignment and electrical insulation. This construction keeps the module producing energy consistently across a wide temperature range from -40℃ to 85℃. When multiple GSPV-310W solar panels are wired together, they create a scalable PV system tailored to the site energy demand.

Monocrystalline energy conversion: The panel uses monocrystalline silicon cells that release electrons when sunlight hits the semiconductor material. These electrons move through metal conductors on each cell, creating direct current that can be harvested and directed into the PV circuit.

Module encapsulation and protection: Cells are encapsulated in EVA between 3.2 mm tempered glass and a TPT backsheet to protect against moisture and mechanical stress. The double-layer anodized aluminum frame provides rigidity, enabling the module to withstand rated wind and snow loads without deformation.

System integration and operation: Power leaves the module through an IP65 or IP67 compatible junction box and factory fitted 4 mm² cables with MC4 connectors. Installers connect multiple panels in series or parallel, then feed the combined DC output to an inverter matched to the 1000V DC system rating.

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.
