Solar Ballast

The solar ballast is a type of solar panel mounting solution that uses weighted objects, or ballasts, to secure solar panels in place instead of traditional roof penetrations or ground anchors.

Ballasts: These are the core components of the system, usually made of concrete blocks, sandbags, or other heavy materials. They provide the necessary weight to hold the solar panels and mounting structure in position. The size and weight of the ballasts can vary depending on factors such as the size of the solar array, wind load requirements, and the type of surface on which the system is installed.

Mounting Frame: This is used to support the solar panels and connect them to the ballasts. The mounting frame is typically made of aluminum or steel and is designed to be lightweight yet strong enough to withstand the forces exerted on the solar panels. It may have adjustable features to optimize the angle of the solar panels for maximum energy capture.

Solar Panels: The actual photovoltaic panels that convert sunlight into electricity. They are installed on the mounting frame and are an essential part of the solar ballast mount system.

 

Gravity and Friction: The ballast mount system works by relying on the force of gravity and the frictional force between the ballasts and the installation surface. The heavy ballasts exert a downward force that keeps the entire system in place. The frictional force between the ballasts and the roof or ground surface prevents the system from sliding or moving, even in windy conditions.

 

Wind Resistance: The design of the solar ballast mount system takes into account wind load calculations. The ballasts and mounting structure are sized and configured to resist the forces of wind. The low profile and distributed weight of the system help to minimize the impact of wind and prevent the solar panels from being lifted or damaged by strong winds.

 

Non-Penetrating Installation: One of the most significant advantages is that it does not require drilling or penetrating the roof or ground. This is particularly beneficial for buildings where roof penetrations are not allowed or could cause leaks or structural damage. It also reduces the installation time and complexity compared to some other mounting methods.

 

Versatility: Solar ballast mount systems can be used on a variety of surfaces, including flat roofs, pitched roofs, and even on the ground in some cases. They can be easily adapted to different site conditions and solar panel layouts.

 

Easy Removal and Relocation: If needed, the system can be easily disassembled and removed without causing significant damage to the underlying surface. This makes it a suitable option for temporary installations or situations where the solar panels may need to be relocated in the future.
