Tips on applying structural adhesive to photovoltaic panels

Can structural adhesives help lower PV panels' costs?

Ian Quarmby from Lord Corp. explains how using a structural adhesive offers can help improve quality (and lower costs) for PV panels, and eliminate maintenance issues for installers — and in both cases, help lower costs.

Can solar panels be mounted with adhesives?

However, research from the Fraunhofer Center for Sustainable Energy Systems has shown that solar panels mounted with adhesives actually have a cooling effect on roofs; boosting solar panel efficiency in the long run.

What are the benefits of structural adhesives for solar panels?

Another concern for solar panel installers is the weight of the system. Structural adhesives eliminate the weight of mechanical fasteners and improve stress distribution, while providing a clean, streamlined appearance.

How thick should a solar panel adhesive be?

The thickness of the adhesive should not be less than 4 mm, and the width should not be less than 10 mm. If possible, apply adhesive on the center of the back of the panel to enhance installation liability. How do clouds and shadowing affect solar panel output efficiency?

How to install a flexible solar panel?

Apply a generous and even layer of adhesive on the back of the flexible solar panel. Make sure you cover everything, from corner to corner. Carefully align your panel with the marked positions on your mounting surface. Precision at this stage will make the difference between a professional-looking job and a clumsy DIY project.

Are structural adhesives a viable alternative to mechanical fasteners?

There are many areas of solar panel construction where structural adhesives would be a viable alternative to mechanical fasteners including the assembly of PV panels and in the supporting framework structure. For example, in photovoltaic cell production, the active silicon layer is often sandwiched between two glass panels.
