Racks for mounting east-west-oriented frame solar panels on flat roofs

How to choose the right construction for mounting east-west solar panels on flat roofs

Introduction:

If you are planning to install solar panels on your home flat roof, you need to make sure that you choose the right mounting system. Racks are the support structures that hold the solar panels in place and keep them stable. Here we will discuss the factors to consider when choosing racks for mounting solar panels with east-west oriented frames on flat roofs.

What are East-West Solar Panel Systems?

East-west framed solar panels are solar panels that are designed to face either east or west instead of directly south, which is the most common orientation for solar panels. The east-west orientation helps maximize the amount of solar energy captured during the morning and evening hours when the sun is low above the horizon.

Why choose flat roofs to install solar panels?

Flat roofs are a popular choice for installing solar panels because they provide ample space for solar panels and make installation easier. In addition, flat roofs are more protected from the wind and are easier to access, making it easier to maintain and clean the solar panels.

Types of racks for mounting framed solar panels with an east-west orientation on flat roofs

There are two basic types of racks for mounting east-west framed solar panels on flat roofs: ballasted and penetrating. Ballast racks rely on the weight of concrete or other heavy elements, as well as the solar panels, to hold them in place, while penetrating racks are bolted to the roof structure. Both types of racks have their advantages and disadvantages, and the choice depends on various factors such as the size of the solar panels, the weight of the racks and the type of roofing material.

Factors to consider when choosing racks for mounting framed solar panels with an east-west orientation on flat roofs

      Roof Load Capacity: Make sure the racks you choose and their counterweights are suitable for the load capacity of your flat roof.

      Roof Material: Different roofing materials require different types of loads, so be sure to choose the right system that is compatible with your roofing material.

      Wind resistance: Consider the wind resistance of the racks, especially if you live in an area with high winds.

      Size and weight of solar panels: Choose racks that are compatible with the size and weight of your solar panels.

      Mounting method: Consider the mounting method of the racks, whether they are ballasted or penetrating, and choose the one that suits your needs.
