HJT Half-Cell Design

Product Overview

The Osda Solar ODA655-33V-MHD monocrystalline bifacial solar panel delivers high power density for utility, commercial, and large rooftop projects. This 655W module uses advanced HJT cell technology and 132 half-cut cells to boost efficiency and lower balance-of-system costs. With module efficiency up to 21.08 percent, more energy can be produced from a smaller footprint. Bifacial construction supports rear-side generation, which enhances yield on reflective surfaces. The module is engineered for 1500V systems, making it ideal for modern string inverters and large arrays. A robust anodized aluminum frame and tempered glass with anti-reflection coating help ensure long-term durability in demanding climates. Backed by a 15-year product warranty and a 30-year power warranty, this panel is designed to support long-term, low-LCOE energy production for investors and system owners who expect reliable performance.

Key Benefits

High power class for fewer modules: Each panel delivers up to 655 watts of power at STC, so large system outputs can be reached with fewer modules. This helps reduce racking, cabling, and installation labor on site.

Bifacial energy gain: Bifacial HJT technology allows the rear side to capture reflected light and add extra energy. In well designed projects, this leads to significant yield improvements and a lower levelized cost of energy.

Excellent efficiency and compact footprint: Module efficiency up to 21.08 percent allows more kilowatt capacity on limited roof or ground areas. This makes the panel ideal where space is valuable or structural limits are tight.

Long-life performance warranties: A 15-year product warranty and 30-year power warranty with only 0.5 percent annual degradation are provided. After 30 years, at least 84.95 percent of the initial power output is expected to remain.

Robust construction for harsh sites: A strong anodized aluminum frame, 2.0 mm tempered glass, and IP67 or IP68 junction box protection help resist wind, snow, dust, and moisture. The design supports stable operation from -40 to 85 degrees Celsius.

Flexible integration with 1500V systems: The 1500V maximum system voltage allows for longer strings and lower BOS costs. This makes the panel a strong fit for utility, C&I, and large ground-mount installations.

How It Works

The Osda ODA655-33V-MHD bifacial solar panel converts sunlight into clean DC electricity using high efficiency HJT monocrystalline cells. Light striking the front glass surface is absorbed by the 132 half cells and converted into electrical current. Additional light reflected from the ground or nearby surfaces is collected by the rear side of the bifacial module, increasing total energy yield. The generated current flows through multiple busbars and low resistance cell connections into the junction box at the rear of the panel. From there, DC power is carried by PV cables to a compatible inverter, where it is turned into AC electricity for on-site loads or grid export. This process runs whenever adequate irradiance is available and is supported by careful thermal management and robust materials, maintaining stable power even in challenging climates.

Front-side power generation: Sunlight strikes the anti-reflection tempered glass and passes through to the monocrystalline HJT cells. These cells create electron flow when photons are absorbed, producing DC power at a rated 655 watts under standard test conditions.

Rear-side bifacial gain: The bifacial structure lets the rear side harvest light reflected from surfaces such as white membrane roofs, concrete, or light gravel. This additional irradiance increases current and boosts total energy generation beyond the front-side rating when mounting conditions are optimized.

Electrical flow and system connection: Current produced by the 132 half-cut cells is collected via multi busbar ribbons and routed to the three-diode junction box. The junction box, with IP67 or IP68 sealing, protects connections while bypass diodes reduce output loss in partial shade. From there, DC output is wired into strings, then combined and sent to 1500V inverters for conversion to usable AC power.

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.
