FAQS about Photovoltaic array support design

How to design a photovoltaic array?

Designing a photovoltaic array requires considerations such as location, solar irradiance, module efficiency, load demand, orientation, tilt angle, shading, and space constraints. It is crucial to optimize these factors for maximum energy production and cost-effectiveness. 2.

Is mechanical design of a PV array within the scope of this document?

Mechanical design of the PV array is not within the scope of this document. BRE digest 489 ‘Wind loads on roof-based Photovoltaic systems’, and BRE Digest 495 ‘Mechanical Installation of roof-mounted Photovoltaic systems’, give guidance in this area.

What are the dynamic characteristics of photovoltaic support systems?

Key findings are as follows. Dynamic characteristics of tracking photovoltaic support systems obtained through field modal testing at various inclinations, revealing three torsional modes within the 2.9–5.0 Hz frequency range, accompanied by relatively small modal damping ratios ranging from 1.07 % to 2.99 %.

Can a solar array support structure withstand a wind load?

Even fixed solar array support structures have sofisticated design, that needs to be analyzed and often improved in order to withstand the wind load. The same applies of course to adjustable designs to an even greater extend. The analysis has to be carried out for many wind directions.

How stiff is a tracking photovoltaic support system?

Because the support structure of the tracking photovoltaic support system has a long extension length and the components are D-shaped hollow steel pipes, the overall stiffness of the structure was found to be low, and the first three natural frequencies were between 2.934 and 4.921.

What are the dynamic characteristics of the tracking photovoltaic support system?

Through processing and analyzing the measured modal data of the tracking photovoltaic support system with Donghua software, the dynamic characteristic parameters of the tracking photovoltaic support system could be obtained, including frequencies, vibration modes and damping ratio.
