Product Overview

The S-Energy SL65-78BGJ-600S 600W bifacial monocrystalline solar panel is engineered for high yield and long‑term reliability. This advanced module uses 156 high efficiency monocrystalline cells to deliver up to 600 W of front side power. Bifacial technology captures additional energy from reflected light on the rear side to further raise total output. With module efficiency up to 21.5%, it is ideal for commercial rooftops, ground mounts, carports and utility projects. The panel operates within an extended temperature range from -40°C to 85°C for reliable performance in harsh climates. A robust 1,500 V system voltage rating supports modern high string designs and reduces balance of system costs. Its durable construction includes 3.2 mm tempered glass with anti‑reflection coating and an anodized aluminium frame. The SL65-78BGJ-600S combines high power density with proven Korean manufacturing quality from S-Energy Co., Ltd. It offers a compelling balance of performance, durability and warranties for long term solar investments.

Key Benefits

High 600W Output in a Single Module: The panel delivers up to 600 Wp of nominal power, enabling powerful arrays with fewer modules per string. This helps reduce racking, wiring and installation labour on large scale solar projects.

Bifacial Energy Gain for Better Yields: Bifacial cell architecture captures light from both front and rear sides. Under suitable installation conditions, this design increases total energy generation compared with standard monofacial panels.

Proven 21.5% Module Efficiency: The SL65-78BGJ-600S reaches panel efficiency up to 21.5%, maximizing power from limited roof or ground space. Higher efficiency supports compact layouts without compromising energy targets.

Robust Mechanical Design for Harsh Sites: The module is tested for heavy snow loads of 5,400 Pa and wind loads of 2,400 Pa. Tempered glass, a strong aluminium frame and high quality junction box components enhance long term durability.

Long Life with 25‑Year Power Warranty: A 12 year product warranty and 25 year linear performance warranty protect your investment. The low annual degradation rate of around 0.6% supports dependable long term energy production.

How It Works

The S-Energy SL65-78BGJ-600S converts sunlight into usable DC electricity using high performance bifacial monocrystalline cells. When sunlight hits the 182 x 91 mm cells on the front, photons are absorbed and create electron flow inside the silicon structure. This flow becomes direct current that is collected through the cell matrix and busbars inside the laminate. At the same time, the transparent rear side and bifacial design allow reflected and diffuse light to reach the back of the cells. This additional irradiation generates extra current, boosting overall power compared with a similar monofacial module. The module operates at a maximum power voltage of 46.3 V and a maximum power current of 12.96 A under STC. This DC output is then routed through MC4 connectors and solar cables to a compatible inverter or charge controller. The inverter converts the DC power into AC for on grid or hybrid systems, or regulates charging in DC coupled designs. Thermal coefficients are carefully controlled so power loss remains modest as cell temperatures rise during operation. Structural elements such as tempered glass, aluminium frame and backsheet protect the cells from weather and mechanical stress. Over decades, the panel continues to generate clean electricity while its warranties safeguard expected performance.

Bifacial Cell Architecture: The module uses bifacial monocrystalline cells that respond to light on both surfaces. Front side glass with anti reflection coating maximizes direct irradiance capture, while the rear side receives albedo light from the mounting surface.

Optimized Electrical Performance: At standard test conditions, the panel delivers 600 Wp with a Vmpp of 46.3 V and Impp of 12.96 A. A power tolerance from 0 to +1% ensures that shipped modules meet or exceed their nameplate rating in real installations.

Thermal and Environmental Stability: The operating temperature range spans from -40°C to +85°C, supporting use in cold and hot climates. Temperature coefficients of -0.35%/°C for Pmax and -0.27%/°C for Voc help keep performance stable as temperatures vary through the day.

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!
