Ballasted Mounting Systems

Ballasted mounting systems rely on the weight of the panels and additional weights to hold them in place. They are convenient and easy to install but may not be suitable for roofs with weight limitations. The installation involves arranging the mounts, placing the weights, and then mounting the panels onto these systems.

Industrial Adhesive Methods

Industrial adhesives provide another effective solution. These high-strength glues bond the mounting hardware to the roof. They are highly resistant to weather and aging but must be used precisely to avoid any gaps that could lead to instability. The installation process involves applying the adhesive to the mounts, placing them on the roof, and securing the panels to the mounts.

Lightweight Solutions for Solar Panel Mounting

Several lightweight options facilitate the mounting of solar panels without the need for drilling, reducing strain on the structure and ensuring ease of installation.

Thin-Film PV Solar Laminates

Thin-film PV solar laminates are exceptionally lightweight solar panel alternatives. These can be directly adhered to the roofing material, making them suitable for roofs that cannot tolerate heavy loads. These laminates are flexible, allowing them to conform to the shape of the roof surface, and their adhesive backing eliminates the need for traditional mounting systems.

Solar Stack – Pedestal Solar Panel Mounting

Solar Stack offers a unique, non-invasive mounting system. This pedestal mounting design does not require roof penetration. Instead, it uses a high-strength adhesive to secure the mounts onto the roof, with the panels then attached to these mounts. The pedestals distribute the weight of the panels evenly across the roof, mitigating the risk of localized pressure damage.

Mounting Tapes and VHB Tapes

Mounting tapes or Very High Bond (VHB) tapes are double-sided adhesive tapes that offer a strong bond. They are resistant to temperature changes and weather effects. Installation involves cleaning the roof, applying the tape to the mounts or directly to the panels, and attaching them to the roof.

No-Drill Solar Panels for Flat Roofs

Flat roofs are common, especially in commercial buildings, and there are numerous non-invasive installation methods suited to them.

Ballasted Mounts

We’ve already mentioned the concept of ballasted mounts, but it’s worth reiterating their effectiveness for flat roofs. These systems are designed to use the weight of the panels and additional ballasts to anchor them securely, eliminating the need for roof penetration.

Plates or Concrete Blocks

Another method is to use plates or concrete blocks as a counterweight to secure the solar panels. This strategy is commonly used with a racking system, where the weight of the blocks keeps the rack and panels in place.

Metal Trusses

Metal trusses, when combined with a weighted system, can offer a reliable non-drilling solution. These trusses are placed across the roof, and the solar panels are then attached to these structures, ensuring they are secure and elevated for optimal sunlight exposure.

Stand-Alone Solar Rack – Mounting Alternative

Stand-alone solar racks provide a viable alternative for individuals who can’t or don’t want to install solar panels directly on their roofs. These racks can be installed on the ground, independent of any building structures.
