Product Overview

The Osda ODA665-33V-MHD 665W HJT bifacial monocrystalline solar panel is engineered for high yield utility and commercial projects. This advanced module combines 132 half-cut monocrystalline cells with cutting edge heterojunction technology for impressive efficiency and stable performance. A bifacial glass design captures light from both sides, which boosts total energy generation over the system lifetime. The panel supports a maximum system voltage of 1500V, making it suitable for large string configurations and optimized balance of system costs.

With a front side maximum power of 665 Wp and module efficiency up to 21.4%, this panel helps reduce required installation area. The bifacial power range from 645 Wp to 670 Wp delivers strong energy yield across diverse site conditions. An extended 15 year product warranty and 30 year performance warranty reflect the robust design. Osda Solar, a global manufacturer based in China, supports the product with comprehensive certifications, reliable manufacturing, and broad project experience worldwide.

Key Benefits

High power density for large arrays: The 665 W output and up to 21.56% efficiency enable more power on every string. System designers can reach target capacity using fewer modules and structures, reducing installation labor and balance of system costs.

Bifacial generation boosts energy yield: Bifacial construction allows rear side light capture from ground reflection and diffuse radiation. This design can increase total energy production significantly over monofacial modules, especially on bright surfaces or snow covered sites.

Durable build for harsh environments: The panel operates reliably from -40°C to 85°C and uses tempered glass with an anti reflection coating. An anodized aluminium frame and a high grade junction box deliver mechanical strength and protection in demanding climates.

Long term performance assurance: A 15 year product warranty is paired with a 30 year power warranty. The guaranteed 84.95% output at year 30 and low 0.5% annual degradation rate help secure predictable long term returns for investors.

Flexible integration for modern systems: Support for 1500 V system voltage enables longer strings and fewer combiner boxes. The panel suits central and string inverters and integrates well into ground mount, tracker, and large rooftop installations.

How It Works

This Osda Solar ODA665-33V-MHD panel converts sunlight into direct current power using 132 half cut monocrystalline HJT cells. Each cell uses a heterojunction structure that improves light capture and reduces internal losses. When sunlight hits the glass surface, photons are absorbed and released as electrical energy within the silicon layers. This energy is collected through a dense grid of fine busbars, then combined into usable current at the module terminals. Bifacial construction allows both front and rear sides to convert light, which increases energy harvested throughout the day.

The module is wired into a string and connected to a compatible inverter through DC cabling and protection devices. The inverter converts DC power into AC electricity suitable for on grid or off grid systems. A 1500 V system rating enables long strings, which minimizes cable runs and improves system design efficiency. Robust encapsulation, tempered glass, and a sealed junction box protect the cells from moisture, dust, and mechanical stress. Over its lifetime, the panel maintains strong output thanks to optimized materials and tight quality control.

HJT monocrystalline cell conversion: Heterojunction cells combine crystalline silicon wafers with thin amorphous silicon layers. This configuration reduces recombination losses and delivers high open circuit voltage and strong temperature performance. As light enters the cell, an electric field guides charge carriers efficiently to the contacts, improving module level power.

Bifacial energy capture: The bifacial design lets both the front and back surfaces generate electricity. Light reflected from the ground, nearby structures, and diffuse sky radiation can be used by the rear side cells. This mechanism unlocks additional kWh per installed watt, especially on high albedo surfaces and open field installations.

System integration and protection: DC output from the panel flows through the junction box, which houses bypass diodes for protection against partial shading. Strings of modules are combined at higher voltage and connected to inverters or combiner boxes. Certified insulation, waterproof IP rated junction boxes, and quality connectors ensure safe and stable operation over decades.

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.
