Product Overview

The Osda Solar ODA675-33V-MHD 670W HJT bifacial monocrystalline solar panel is engineered for high yield utility and commercial projects. This advanced module combines half-cut 210×105 mm cells with heterojunction technology for excellent efficiency and stable output. With a bifacial design, additional energy is harvested from reflected light on the rear side of the panel. The front side delivers up to 670 Wp with up to 21.56% efficiency, which helps reduce levelized cost of energy. Long life performance is supported with a 15 year product warranty and a 30 year power warranty. Power output is guaranteed at 84.95% of the original value by year thirty. The module is designed around a 1500 V system voltage to suit modern high string configurations. Robust construction, tempered glass, and an anodized aluminium frame ensure strong mechanical load resistance. Osda Solar manufactures this panel in China and supports global distributed photovoltaic projects. This product suits ground mount plants, commercial rooftops, and large off grid systems that demand reliable high power density.

Key Benefits

High power density for large arrays: Up to 670 Wp per module allows more installed capacity on limited racking space. Fewer panels are required to reach target system sizes, which can lower balance of system costs.

Bifacial energy gain: The bifacial construction captures light on both sides of the module. Extra yield can be realized over reflective surfaces such as light gravel, snow, or white membranes.

Reliable long term output: A 30 year power warranty guarantees at least 84.95% of initial output at year thirty. Degradation is controlled at around 0.5% per year, supporting stable revenue forecasts for project owners.

Optimized electrical performance: The module delivers a Vmpp of 38.2 V and Impp of 17.54 A at STC. These values suit high current string inverters and allow flexible string design on 1500 Vdc systems.

Robust mechanical design: Tempered glass with anti reflection coating and an anodized aluminium frame provide strong durability. The panel is engineered to withstand demanding outdoor conditions when installed correctly.

High efficiency monocrystalline cells: HJT monocrystalline cells with 21.56% peak efficiency help maximize kWh output from every square meter. This supports projects where roof or land area is constrained.

How It Works

Sunlight strikes the front and rear sides of the Osda Solar ODA675-33V-MHD panel and is converted into electricity. Each HJT monocrystalline cell generates direct current when photons are absorbed by the silicon layers. The half cut cell layout reduces internal resistive losses and improves shade tolerance across the module. Front side power reaches up to 670 Wp under standard test conditions with 1000 W per square meter irradiance. Rear side contribution increases total energy when the module is installed above reflective ground or roofing. The direct current from the panel is connected into strings and routed to a solar inverter. The inverter then converts DC into AC power which can be used on site or exported to the grid. Optimized temperature coefficients support more stable output as cell temperatures rise in strong sun. System designers can combine these modules in high voltage strings thanks to the 1500 V rating. Strong encapsulation, junction box sealing, and appropriate fusing help keep the system safe over its lifetime.

Bifacial light capture: Front glass with anti reflection coating captures direct and diffuse sunlight efficiently. The rear side also receives reflected light from surfaces below the array, increasing annual kilowatt hour production when site conditions are favorable.

HJT monocrystalline conversion: Heterojunction cell stacks combine crystalline silicon with thin amorphous layers. This structure supports high open circuit voltage and excellent low light behavior, which helps maintain output during cloudy conditions or early and late sun angles.

System integration and protection: A three diode junction box protects strings from reverse current and partial shading effects. The 30 A series fuse rating suits high current designs, and the 1500 V maximum system voltage allows long strings that reduce cabling and combiner hardware.

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.
