6 FAQs about [Vertical pull-out force test of photovoltaic bracket]

What is a pull out test?

System optimization and execution performance files. Zoning The objective of the Pull Out test is to evaluate the behavior of the profiles used in the support structures of the tables or panels of a photovoltaic installation, based on the characteristics of the different types of existing terrain.

Do geotechnical reports have a pull test?

Geotechnical reports often tend to be very conservative in their embedment depth recommendation, and a pull test should be conducted after selection of foundation type in order to attempt to minimize embedment depth, and thus length and cost of screwed or driven foundations.

Why do PV plants need double horizontal load tests?

When PV plants are designed with fixed type panels, the lateral load is less limiting and the number of this type of tests could be reduced. When conducting double horizontal load tests, the reaction equipment will need to be duplicated. This reduces the shear stress and maintains the bending moment at the base.

What is a pull test?

A pull test uses a strain gauge to measure vertical and lateral resistance up to the forces required by the PV support structure engineer’s calculations for wind and snow load requirements.

How high should a pile be for a photovoltaic plant?

In any case, for the types of piles that are being used in the foundations of photovoltaic plants, it is recommended that the height of load application will be in order of 1,0 m and in no case exceeding 1,5 m.

How were PV support structures made?

The driven piles used in the earlier PV support structures were made from hot rolled structural steel shapes such as I beams which were then fabricated by cutting them to length and then drilling, routing, or cutting with lasers holes and slots to enable other parts to fit onto them.
