As the cost of bifacial modules becomes comparable to that of standard monofacial modules, industry interest has grown. A
module that generates power from the front and rear translates to more power per module. More power per module translates to
more power per area of installation. It might seem that more power per installation would translate to more power for less cost.
However, it is far more complex; especially when it comes to defining how much additional power gain is obtained by using bifacial
panels with single axis trackers. Why is the bifacial and single axis tracker opportunity more complex than it might appear on the
surface? We will outline the challenges inherent in accurately defining and calculating Levelized Cost of Energy (LCOE) for solar
installations utilizing bifacial modules with trackers. Knowing how to accurately calculate LCOE for bifacial projects can mean the
difference between having a profitable project or not. The challenges we will cover are Module Technology, Impact of the Tracker
System and Installation Parameters, Performance and Financial Modeling, and Tracking Algorithms. We will also discuss how Array
Technologies is conducting research to address and overcome these challenges with science-based solutions. Our goal is to develop
tools and formulas that will allow us to more accurately calculate the true cost and benefits of using bifacial modules and best to
utilize them for projects in order to minimize LCOE for our customers’ projects. Whether CAPEX-focused or OPEX-focused,
utility-scale project stakeholders are keen to understand the benefits and metrics to evaluate bifacial technology for the future of
PV power plants.
