The newest report from the International Energy Agency’s Photovoltaic Power Systems Program (IEA-PVPS) covers finest practices for optimizing bifacial PV monitoring techniques and discusses key areas for enchancment.
The IEA-PVPS has revealed a report containing finest practices for optimizing bifacial photovoltaic monitoring techniques.
The Task 13 report follows the actual fact sheet on bifacial PV modules and superior monitoring techniques, revealed in July. It says that PV techniques utilizing bifacial modules and single-axis trackers have develop into the main configuration for utility-scale PV installations worldwide, with greater than 90% of modules bought utilizing bifacials. cells and greater than 60% of the market share for PV system use. single axis-trackers.
“The mixed advantages of the tracker and bifacial know-how lead to a convincing cost-performance ratio,” mentioned Ulrike Jahn, Task 13 supervisor. “This makes bifacial monitoring techniques essentially the most reasonably priced choice in almost 90% of areas worldwide.”
The report states that common tracker positive factors of 15% to twenty% and bifacial positive factors of two% to 10% are additive, with these techniques offering the bottom levelized energy prices.
The IEA-PVPS says its newest report is meant to assist corporations and builders design and construct PV techniques that take into consideration all of the elements that affect system efficiency. It options insights from main tracker corporations and house owners and operations of PV techniques worldwide, together with knowledge obtained from interviews with 16 tracker corporations representing greater than 87% of the worldwide market share between 2012 and 2021.
The report additionally included a blind modeling examine, the place contributors had been requested to design six hypothetical PV techniques towards a given system design and climate knowledge. The comparability confirmed as much as ~100% distinction between the again facet irradiance predictions of various fashions and contributors, resulting in the report’s conclusion that prediction fashions for bifacial monitoring techniques ought to be enhance.
“Also, predictions for module temperatures and even monitoring angles fluctuate surprisingly between totally different contributors,” the report continued. “More high-quality, validated datasets are wanted for mannequin builders to make sure fashions are extra constant.”
The report identifies key analysis areas, together with the necessity for longitudinal research of assorted tracker applied sciences in numerous climates to enhance single-axis knowledge reliability and stability. trackers. It additionally requires analysis into low-cost, sturdy supplies and optimum placement methods to find out whether or not albedo enhancement ought to develop into normal observe.
The report added that using bifacial modules and trackers for agrivoltaic techniques is “notably thrilling,” as a result of if confirmed possible, “it might create an unlimited subject for renewable vitality technology and assist many small international locations can profit from PV vitality. with out sacrificing land for agriculture.” It outlines the problem of lowering design complexity and variations to allow standardization and high-throughput manufacturing.
In May, the IEA-PVPS launched an motion group on agrivoltaics, which is anticipated to lead to a report overlaying world traits, which is scheduled to be launched on the finish of subsequent 12 months.
