N-Type TOPCon

Product Overview

The Guorun Energy 510 510W bifacial HJT monocrystalline solar panel delivers high efficiency and long term reliability for demanding projects. This advanced module is engineered for residential, commercial and light industrial installations where every watt must count. With a rated maximum power of 510 Wp and panel efficiency up to 22.95 percent, it helps unlock more energy from limited roof or ground space. Its bifacial HJT cell design allows energy capture from both the front and rear surfaces in suitable mounting conditions. The panel uses 108 high quality monocrystalline cells and a robust anodized aluminium frame for structural strength. An anti reflection glass surface improves light absorption while protecting cells from harsh environments. The module is designed for systems up to 1500 volts, giving flexibility for modern string layouts. Guorun Energy has combined efficient cell technology, durable materials and a strong warranty package to support long term energy yield. Installers and system designers can rely on its stable performance, even when temperatures shift between harsh cold and intense heat. This solar panel has been created to balance output, durability and lifetime value for a wide range of solar projects.

Key Benefits

High power density for tight spaces: A rated 510 Wp output with up to 22.95 percent efficiency delivers more power per square meter, ideal where roof or ground area is limited.

Bifacial HJT technology for extra yield: Bifacial HJT cells can harvest light from both sides of the panel when mounted over reflective surfaces, helping increase total energy production across the year.

Reliable long term performance: The 15 year product warranty and 30 year power warranty with only 0.32 percent annual degradation support dependable output for decades of operation.

Robust design for harsh conditions: Anodized aluminium frame, IP68 junction box, 2 mm anti reflection glass and wide operating temperature range help withstand challenging weather and installation environments.

Flexible system integration: A 1500 volt maximum system voltage, MC4 connectors and 4 mm2 cabling simplify integration into modern string inverters and commercial system designs.

Precision power tolerance: A tight 0 to plus 1 percent power tolerance helps ensure delivered output meets or exceeds the stated rating, supporting accurate system yield forecasts.

How It Works

This Guorun Energy 510 bifacial HJT monocrystalline solar panel converts sunlight into usable direct current electricity using advanced cell technology. Each of the 108 high efficiency cells generates an electric current when photons strike the silicon junction. The cells are wired together so voltage and current combine to reach a maximum power point of 510 Wp under standard test conditions. A transparent front glass with anti reflection coating increases the amount of light that reaches the cell surface. Because this is a bifacial HJT module, the rear side can also capture reflected and diffuse light. This effect is strongest above bright surfaces like light concrete, white membrane roofs or reflective gravel. The generated direct current flows through integrated 4 mm2 cables and MC4 connectors to the rest of the system. A compatible inverter then converts the direct current to alternating current suitable for building loads or export to the grid. Built in safety ratings, including IP68 junction box protection and a 1500 volt system limit, support secure long term operation. Careful installation and correct string design will help this panel operate close to its maximum power point across many years.

Bifacial HJT cell operation: HJT cells combine thin amorphous layers with crystalline silicon to reduce recombination losses and raise efficiency. The bifacial structure allows light entry from both the front and back surfaces, improving total kilowatt hour yield where rear side irradiance is available.

Maximum power point and output: At its maximum power point the module delivers about 34.63 volts and 14.73 amps, producing the rated 510 Wp. An inverter tracks this point automatically, adjusting operating voltage to keep the panel close to its most efficient region as sunlight and temperature change.

Thermal behavior and energy yield: The panel includes favorable temperature coefficients, with Pmax decreasing by only about 0.24 percent per degree Celsius rise. This helps maintain higher output during hot conditions, while the wide -40 to 85 degree operating range supports reliable performance in very cold and very warm climates.

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.
