Satellite-derived datasets to measure ground albedo for bifacial PV

A researcher from the NREL has set up a series of datasets of measured ground albedo values using measurement network data in the U.S. and data contributed by the PV industry. The measured albedo datasets are intended to help developers of ground-mounted PV projects in making a choice between monofacial and bifacial panels.

Building on bifacial momentum

Getting the most out of a bifacial module requires a rethink at almost every level of system design and the industry is hungry for field data generated by such systems to better inform energy yield modeling and define the best approaches to maximizing yield at minimal cost. In May, the U.S. National Renewable Energy Laboratory began a three-year study into bifacial performance which is beginning to yield results.

Webinar Q&A: Performance modelling for accurate energy output and yield prediction of bifacial PV systems

In our recent webinar, held in partnership with JinkoSolar, on the impact of bifacial modules and modelling their yield under varying environmental conditions and system setups, JinkoSolar’s Andrea Viaro discussed innovations in bifacial module design, and implementing these into a system to positively impact the return on investment. Teun Burgers, a Senior Researcher at ECN.TNO also delved into the simulation of bifacial PV systems, and treated us to a closer look at ECN’s BIGEYE simulation model. Here, the two presenters answer some more of the questions posed by the audience during the webinar.

Longi unveils results of bifacial module test

The exercise, conducted on Longi PERC bifacial modules by Germany’s TÜV SÜD at a test field in China, showed surprisingly higher gains in panels getting light reflection from painted-surface and grassland albedo. It also showed, Longi claimed, bifacial panels operate at lower temperatures than single-sided alternatives.

A common language for bifacial PV

This week pv magazine was in Amsterdam for the sixth edition of the BifiPV workshop, where the discussion focused on the impressive achievements made by bifacial solar modules and the challenges the technology faces as it moves toward mainstream adoption.
