Product Overview

The Green Sun Solar GSPV-295W 295W monocrystalline solar panel is designed for reliable energy production in residential, commercial, and small industrial projects. This robust 66‑cell module is built around high quality monocrystalline solar cells that deliver stable power output under standard test conditions. A durable double‑anodized aluminum frame, 3.2 mm tempered glass, and weather resistant backsheet support long term outdoor operation in varied climates. The panel works confidently in hot summers and cold winters thanks to its wide operating temperature range from minus forty to eighty five degrees Celsius. With a maximum system voltage of 1000 V DC, it can be integrated into many common inverter and system designs. This module offers dependable performance for grid tied arrays, off grid systems, and project integrators who need a proven, bankable solar panel.

Key Benefits

Reliable 295 W power output: Each module is rated at 295 watts under standard test conditions, supporting efficient array design and predictable system performance across a wide range of installations.

High quality monocrystalline cells: The panel uses 66 monocrystalline 156 x 156 mm cells that enhance energy yield, giving better power density than many older polycrystalline modules in the same footprint.

Durable construction for harsh sites: A 3.2 mm tempered glass front, EVA encapsulation, and TPT backsheet are combined with a robust aluminum frame to handle up to 2400 Pa wind and 5400 Pa snow loads.

Proven long term performance: A linear power output warranty helps ensure the module retains strong production over decades, supporting long project lifecycles and attractive energy yields.

Flexible application options: With 1000 V system voltage, MC4 compatible connectors, and industry standard dimensions, the panel integrates smoothly with common mounting, wiring, and inverter platforms.

How It Works

The Green Sun Solar GSPV-295W panel converts sunlight into usable direct current electricity through its array of monocrystalline silicon cells. When sunlight hits each cell, photons of light free electrons inside the silicon structure and create an electric current. The 66 series connected cells combine their voltage to reach the rated output under standard test conditions of one thousand watts per square meter and twenty five degrees Celsius. Current flows through the factory fitted 4 mm² cables and MC4 compatible connectors to the rest of the solar power system. An inverter then converts the direct current into alternating current that matches local grid or load requirements. Over time, proper installation, correct string design, and adequate ventilation help this module deliver stable daily energy production in a range of climates and orientations.

Monocrystalline energy conversion: Each 156 x 156 mm monocrystalline cell uses a uniform crystal structure that supports efficient charge movement and strong electrical output. The cells are wired in series to increase total voltage, while their current adds together through the busbars and connectors to achieve the panel’s rated amperage.

Encapsulation and protection layers: The cells are encapsulated in EVA to hold them firmly in place, protect them from moisture, and maintain optical clarity over many years. A tough 3.2 mm tempered glass sheet on the front and a TPT backsheet on the rear shield the cells from mechanical stress, weather exposure, and electrical leakage.

System integration and operation: The junction box, rated to IP65 or IP67 depending on configuration, safeguards electrical connections while allowing secure plug and play cabling. When wired into strings that respect the 1000 V system limit and inverter specifications, these panels supply consistent DC power that supports both grid tied and off grid solar systems.

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.
