Guorun Energy 515 515W Bifacial HJT Solar Panel

Model 515 | HJT | 108 Half-Cell | Bifacial | 1500V System Voltage

515 Wp
Max Power Output
23.17%
Module Efficiency
108
Half-Cell Design

Product Overview

The Guorun Energy 515 is a high-output bifacial HJT solar panel built for strong performance and modern solar installations. It combines a 515 Wp maximum power rating with a 23.17% module efficiency, helping maximize energy generation in limited roof or ground space. The monocrystalline cell structure supports stable conversion performance and dependable operation. A 30-year power warranty and a 15-year product warranty add long-term confidence. Its anti-reflection glass, anodized aluminium frame, and IP68 junction box support durability in demanding outdoor conditions. This panel is suitable for projects that need high power density, reliability, and efficient space use.

Key Benefits

High power output: The panel delivers 515 Wp for strong generation potential across commercial and residential systems.

Excellent efficiency: A 23.17% efficiency rating helps produce more electricity from the same installation area.

Bifacial energy gain: The bifacial design can capture light from both sides, improving yield in suitable mounting conditions.

Long service life: A 15-year product warranty and 30-year power warranty support long-term project planning.

Durable construction: Anti-reflection glass, an anodized aluminium frame, and IP68 protection improve outdoor reliability.

Wide operating range: The module is designed for operation from -40 to 85 °C, supporting varied climates.

How It Works

The Guorun Energy 515 solar panel converts sunlight into electricity through advanced HJT cell technology. The monocrystalline structure supports efficient electron flow and consistent power generation. Its bifacial construction allows the rear side to use reflected light, which can increase total output in the right installation environment. The panel is engineered for stable electrical performance across changing temperatures and weather conditions. With a high voltage system rating and strong mechanical protection, it is designed to integrate smoothly into modern solar arrays.

HJT cell conversion: Heterojunction technology improves charge separation and supports high efficiency. This helps the panel generate strong output under everyday solar conditions.

Bifacial light capture: The rear side can absorb reflected sunlight from the installation surface. This can increase energy yield where the mounting setup supports rear-side exposure.

System integration: The 1500V maximum system voltage and MC4 connectors support efficient array design. This makes the module suitable for larger solar projects and compatible layouts.

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.
