The year-long field test (September of 2018 to September of 2019) highlighted that bifacial modules deployed on its SF7 Bifacial tracker in a 2P configuration exhibit a Bifacial Gain that is 2.1% higher than that of the same modules in 1P configuration. Image: Soltec
Single-axis solar tracker firm, Soltec has reported a range of bifacial module and tracker performance results from its Bifacial Tracker Evaluation Center (BiTEC) in Livermore, California, showing an advantage in using a 2P configuration and an overall bifacial gain of 15.7%.
The year-long field test (September of 2018 to September of 2019) highlighted that bifacial modules deployed on its SF7 Bifacial tracker in a 2P configuration exhibit a Bifacial Gain that is 2.1% higher than that of the same modules in 1P configuration.
Bifacial modules also provided 15.7% more Bifacial Gain under high albedo conditions (55.6%) (white sand or snow-covered ground) and 9.6% under medium albedo conditions (29.5%), compared to monofacial modules. The company also reported that for cultivation areas with an albedo of 19.9%, the bifacial gain of a 2P SF7 bifacial tracker is 7.3%.

The results in this annual report were made with Jolywood’s JW-D72N-355 bifacial modules.
Such field testing has become a key requirement to support better data analysis of the overall performance gains of bifacial modules that can then be used with modelling software improvements for bankability.

Virtually all PV modules for large-scale utility-based solar sites are imported to the US, especially from Chinese companies using manufacturing sites across Southeast Asia. This puts extreme pressure on US site developers, EPCs and investors, in understanding fully the differences between the companies offering imported PV modules How credible are the companies supplying the products? What is the financial health of the parent entity? Where is the module produced, and is this undertaken in-house or through third-party OEMs? What is the supply-chain for the module sub-components including wafers and cells? And then, how will the modules perform in the field, and is it possible to gauge reliability levels benchmarked against competitors? This webinar will provide insights from two of the leading experts in PV module manufacturing, supply, performance and reliability: Jenya Meydbray of PV Evolution Labs and Finlay Colville from PV-Tech. The 1-hour session will include presentations from Jenya and Finlay, and then a brand-new supplier scorecard matrix that combines the key outputs from PVEL's Module Reliability Scorecard and PV-Tech's PV ModuleTech Bankability Ratings, with specific focus on module supply and use in the US market.
