What is a Solar Racking System?

Solar Racking System

A solar mounting system securely attaches solar panels to various surfaces, like your roof or garden. Solar firms utilize mounting products to secure equipment during installation. Solar mounting, also known as solar racking, is typically crafted from aluminium, suitable for rooftop installations due to its durability and lightweight nature compared to alternative materials.

Types of Solar Racking Systems

If you want to choose the best solar panel racking system for your solar energy project, you need to get familiar with the racking options available.

Roof Mount

Roof mounts are a popular solar racking solution. They attach to the roof, providing a stylish and effective method to switch to solar power without using up additional land. Perfect for those wanting to optimize their current space, roof mount systems focus on maximizing sun exposure while leaving your ground free for other purposes.

Flat Roof Mount

The flat roof setup offers stability and maneuverability in choosing the orientation and tilt. While it’s typically the preferred choice for commercial roof-mounted systems, it’s also viable for residential use if the roof is flat. This system involves designing a ballasted concrete structure (similar to an in-ground mount) that allows for placing the modules at a specific angle.

Solar panels can be attached to the concrete base, reducing the need for metal materials in the mounting structure. If the system features solar tracking, the aluminium structure’s base is fixed to the concrete, providing mobility for the solar panels.

Floating Solar Mount

The advanced floating solar mount system uses a smart anchoring mechanism to secure solar panels on water bodies. This PV racking system cleverly uses anchor points, usually situated under the water, though surface anchoring can work well too. The installation process is carefully planned to suit specific water area conditions, ensuring stability and durability.

Depending on the water level changes, the system uses different anchoring techniques. For water level changes up to 1 metre, the system uses sinkers or stones attached to ropes. When the change is less than 3 metres, it combines sinkers or stones with ropes and springs for extra support. If the water level change exceeds 3 metres, the anchoring method involves sinkers or stones connected with winch ropes for maximum stability.

Carport Mount

A solar carport is like a canopy of solar panels that covers parking spaces for homes, businesses, and industries. By installing one, owners can easily generate power to run their operations or earn extra income by selling power. Solar carports also protect cars from the elements, making them very attractive to car dealerships.

Pole Mount

Pole mounts take your solar panels off the ground, mounting them on poles. This option is great for maximizing production by elevating panels above obstacles that might cast shade. Plus, some pole mounts even track the sun, adjusting the panel’s angle to soak up every ray.

By strategically positioning the solar panels at the optimal height and angle, pole mounts can significantly increase the efficiency of the solar energy system. This type of mount is particularly beneficial in areas with limited space or irregular land surfaces, making it a versatile solution for various installation scenarios.

Ground Mount

Ground mount systems allow for optimal placement and angle adjustment, ensuring your panels get prime sunlight exposure without roof limitations. Ideal for homeowners with sufficient land, ground-mount solar systems offer the flexibility to install panels in the most efficient orientation and tilt, potentially yielding higher energy production. This option can be particularly appealing for those with roofs that are not ideal for solar installation due to direction, inclination, or structural concerns.

Tracking Mount

Tracking solar PV mounting system is mainly applied to large-scale solar power plants in low-latitude areas. One motor and control system makes the whole solar module array track automatically. The unique linkage structure and slewing bearing ensure the stability of the whole system, with a low failure rate and low maintenance cost.

It is a good choice for large-scale solar power plants, offering roughly 20% more power generation compared to fixed systems.
