Advantages and disadvantages of flat roof solar mounted PV bracket

Reasonable photovoltaic support foundation can improve the wind load resistance and snow load resistance of the solar pv mounting systems. Rational use of the characteristics of solar mounting structures, we can further optimize its dimension parameters, save materials, and make contributions to further reduce the cost of solar racking system.

The following is a comparative analysis of the advantages and disadvantages of different foundation.

1.Cement pier foundation support

Flat roof concrete foundation support is currently the most commonly used installation form in flat roof solar power stations. According to the form of foundation, it can be divided into strip foundation and independent foundation; the connection between the support column and the foundation can be connected by anchor bolts or directly embedded the columns into the concrete foundation. Advantages: Good wind resistance, no damage to roof.

Disadvantages: Long construction period.

2.Concrete ballast bracket

Ballasted solar mount systems are designed without penetration on rooftop or pouring of concretes. Specially suitable for residential concrete roof power station. It have been treated with high quality anti-corrosion treatment and is suitable for installation in harsh weather conditions with long service life.

Advantages: Easy installation and save construction time

Disadvantages: Wind resistance is relatively poor.
