New Testing Facility Launches: Is the Future of Utility-Scale Solar Projects in Bifacial?

In 2018, bifacial solar technology has become one of the most prominent technology trends in the global PV industry. With the potential to significantly increase energy output by producing energy from both sides of the solar cell, the technology holds considerable promise. Pioneering solar tracking firm Array Technologies is taking a leadership role in the research and development of the combination of the two technologies, through its partnership with a New Mexico-based National Laboratory. The new facility will serve as the test ground for analyzing and validating field data to determine optimal system output utilizing bifacial modules with tracking technology under a range of variables and conditions.


“We’re really excited about the opportunity this partnership presents, as the national lab brings cutting-edge instrumentation capabilities accompanied by robust data. This will allow us to arrive at independent data-driven conclusions that will support the industry’s modelling of bifacial behavior and output,” said Ron Corio, founder and chief innovation officer at Array Technologies, “Current models for bifacial and tracking are in the early phases of development, and right now it is really about delivering the specifics that will allow for modelling which the financial community can embrace.”


The testing facility project will run through November 2018, and Array expects to yield data as early as the end of August. The joint project will be testing two rows of modules utilizing bifacial products from six manfuacturers: Canadian Solar, Jolywood, Hanwa Q Cells, Longi, Trina and JA Solar. Both full cell and half-cell solar modules will be tested in conjunction with solar tracking design variants at the national laboratory site.


“There are a wide range of variables for bifacial technology with solar trackers. We are looking at mounting configurations, shading from the tracker, ground albedo, and the spacing between modules and rows, as some examples,” said Jim Fusaro, chief executive officer at Array Technologies, “There is significant potential for the  combination of the two technologies. Regardless of output gains, Array’s focus will  be to deliver the highest value to our customers, such as the lowest LCOE and highest ROI.   


Array Technologies, who has been pioneering innovations in solar tracking for 29 years installed its first bifacial system in 2009. The company had been running additional experiments and collecting data on bifacial tracker sites for a year prior to the launch of the national testing facility site.

RBI Solar - Dahlia Has You Covered

What if you could maximize the Ground Coverage Ratio (GCR) on your next project and not have to worry about the complicated variables that come with a tracker system? With a low tilt and clearance design, Dahlia® has the highest GCR of any fixed-tilt system in the marketplace. The system is available in three tilt options (7.5, 10 and 12.5 degrees) and designed to accommodate any sized PV module. The lightweight system is engineered with fewer components, several of which are shipped to job sites pre-assembled. This design feature reduces freight costs and rapidly trims the amount of on-site installation time required to complete construction. Maximizing PV coverage on a site can lead to an increase of production, which creates greater financial return for project owners. Over 100 MW of Dahlia® projects have been deployed across the United States, in regions of variable snow and wind loads. How much can Dahlia® cover and save you on your next project?
