Adopting bifacial solar panels is changing into extra outstanding within the solar business. As utilization will increase, research reveal that mainstream racking options restrict bifacial rear-side era. In this text, we are going to focus on the advantages that include utilizing a racking system designed particularly for bifacial solar panels.

With our eyes on the horizon and our boots within the grime, Terrasmart is ready to present true agnostic options, in each product and know-how, for any terrain. Learn how.

Traditional Racking Solutions. Mainstream racking options are constructed with monofacial solar panels in thoughts. Most racking methods are designed with wind deflectors and brackets that run alongside the again aspect of the panels, with ballast blocks instantly underneath the panels or between the PVs. This conventional design creates obstructions underneath the panels, which in flip will trigger shadowing that forestalls gentle from reaching the rear-side of the panel.

It is frequent for racking methods to take care of a low profile, however – for bifacial panels – the next tilt and clearance with the roof will permit the rear-side of the panel to reap extra energy. While monofacial panels can function unaffected in these racking circumstances, bifacial solar panels can see a critical lower in rear-side energy manufacturing when put in on conventional racking methods.

Keep Both Sides of the Bifacial Panel Exposed to Light. Maximizing the efficiency of bifacial panels depends on a easy idea: permit each side of the panel to get as a lot publicity to gentle as attainable. Bifacial solar panels carry out most effectively when rail-based racking methods are used. These options work by putting rails alongside the perimeter of the solar panels, leaving the rear-side of the panel uncovered to gentle and freed from obstruction. Cables will be tucked alongside the rails minimizing the shading on the panels.

To get much more energy manufacturing from the rear-side of the panel, a racking system that enables to extend the lean to not less than 10° or 15° is most well-liked. In addition, a racking system that raises the peak of the system as much as 10″-24″ clearance on the entrance and that’s designed to have bigger interrow distance may even enhance the bifacial positive factors.

Generate Up To 30% More Energy. When solar customers select bifacial know-how for his or her panels, they enhance their potential for energy era by as much as 30% –making the selection to make use of an optimized racking system the very best funding for customers who wish to enhance energy manufacturing and enhance the return for his or her funding.

Have you checked out our YouTube web page?

We have a ton video interviews and extra content material on our YouTube web page. Recently we debuted Power Forward! — a collaboration with BayWa r.e. to debate larger stage business matters in addition to greatest practices / traits for operating a solar enterprise as we speak.

Our longer operating aspect venture is The Pitch — wherein now we have awkward discussions with solar producers and suppliers about their new know-how and concepts in order that you do not have to. We’ve discusses all the things from residential rail-less deck attaching and home solar financing to large-scale energy storage worth stacking and utility-driven new home solar + storage microgrids.

We additionally put up our Project of the Year bulletins there! Interviews with this 12 months’s winners might be up beginning the week of Nov. 8. Head there and subscribe as we speak to remain on prime of all this additional stuff.
