Product Overview

The Guorun Energy 525 HJT Monocrystalline Bifacial Solar Panel delivers high power in a compact footprint, ideal for space constrained rooftops and commercial arrays. This advanced module uses innovative HJT bifacial technology and efficient monocrystalline cells to reach a maximum output of 525 Wp with panel efficiency up to 23.62 %. The design has been engineered for long term reliability, supported by a 15 year product warranty and a 30 year performance warranty with only 0.32 % annual degradation. Stable operation is maintained across a broad temperature range from -40 °C to 85 °C, making it suitable for diverse climates and demanding sites. A robust anodized aluminium frame, anti reflection coated glass, and IP68 junction box help protect the module against moisture, dust, and harsh weather. The Guorun Energy 525 panel has been developed for residential, commercial, and utility scale projects that demand reliable power density and extended lifetime value. Installers benefit from standard MC4 connectors and 1500 V system voltage compatibility, which simplify array design and allow longer strings. With its powerful combination of high efficiency, bifacial energy gain, and durable construction, this module supports lower levelized cost of energy over decades.

Key Benefits

High power density for limited roof space: The 525 Wp output and up to 23.62 % efficiency allow more energy from fewer modules, which helps maximize production on compact roofs and commercial structures.

Bifacial HJT technology for extra yield: Bifacial construction lets the panel harvest light from both front and rear surfaces, which can increase total energy generation on reflective surfaces and well designed mounting systems.

Long term performance stability: A 30 year power warranty with 90.3 % remaining output and a 0.32 % degradation rate per year delivers dependable generation and predictable returns throughout the system life.

Robust build for harsh environments: The IP68 junction box, anodized aluminium frame, and 2 mm anti reflection glass help shield components from moisture, dust, and mechanical stress in challenging outdoor conditions.

Flexible system design and integration: Compatibility with 1500 V systems, 30 A series fuse rating, and standard MC4 connectors allows efficient string layouts and simple integration with modern inverters and mounting hardware.

Optimized thermal and electrical behavior: Low temperature coefficients for power, voltage, and current support strong performance in hot climates, while the 45±2 °C nominal operating temperature enhances efficiency under real world irradiance.

How It Works

This Guorun Energy 525 HJT Monocrystalline Bifacial Solar Panel converts sunlight into usable direct current electricity through high efficiency semiconductor cells. Each of the 108 monocrystalline cells absorbs incoming radiation on the front surface while the bifacial design also captures reflected light from the rear side. The generated current is collected by conductive busbars and routed through the module’s internal circuitry toward the junction box at the rear. From there, standard MC4 connectors and 4 mm² DC cables transfer power to string wiring and on to the inverter, where it is converted into alternating current electricity. Carefully tuned electrical characteristics, such as a 35.01 V voltage at maximum power and 15 A current at maximum power, allow efficient operation with modern inverters and 1500 V DC systems. Thermal behavior is managed by low power temperature coefficients, which help reduce output losses during hot summer days and under high irradiance. The entire assembly is sealed beneath anti reflection coated glass and framed in anodized aluminium, which maintains structural integrity and long term reliability in outdoor conditions.

Bifacial HJT energy conversion: Heterojunction technology combines crystalline silicon wafers with thin amorphous layers to improve charge collection and reduce recombination losses inside each cell. The bifacial structure then exposes both sides of the module to light, so energy is produced from direct sunlight as well as reflected and diffuse radiation around the array.

Optimized operating point and string design: At standard test conditions, the panel reaches 525 Wp at a voltage of 35.01 V and a current of 15 A, which defines the maximum power point for system designers. Open circuit voltage of 42.31 V and short circuit current of 16.06 A give planners clear boundaries for series and parallel configurations within 1500 V arrays.

Durable protection and safe operation: The 2 mm anti reflection glass increases light transmission while shielding the cells from impact and weathering over decades of service. An IP68 rated junction box, secure MC4 connectors, and a 30 A series fuse rating work together to support safe operation, reduce moisture ingress risk, and maintain reliable energy delivery in demanding installations.

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.

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!
