Spain-based mounting system supplier Alusín Solar has developed an adhesive mounting structure for rooftop photovoltaic systems which it believes is applicable to any type of solar module.
The system is currently being tested on a 9.8 MW self-consumption solar project under construction by the Spanish utility Endesa, part of the Italian energy company Enel.
The main advantage of the system is that the roof is not perforated in any way. “As no hole is made, the risk of leakage is eliminated, which [is] something very important, for example, in ham dryers ”, said the managing director of Alusín Solar, Javier Font, pv magazine.
The Gulpiyuri 30 system is made up of aluminum bars which, instead of being fixed to the roof with screws, are fixed with double-sided adhesive. According to the manufacturer, this adhesive guarantees the mechanical strength and durability necessary to mount the aluminum profiles that will hold the solar panels. Font claims that the system works for any type of solar panel “because the structures fit into any panel”.
The system was first used two years ago in Cantabria. Inekya was the EPC and Sice Renovables the installer. “The first project was developed in 2019 and remained in embryonic mode until they commissioned us [for] this major project, which served as an accelerator, ”explains the director of Alusín Solar.
The system must be installed with a special cleaning technique. “All aluminum profiles should be cleaned with a specific high alcohol-based product to ensure the removal of any type of oil or dirt,” Font explained. “Then a specific primer is applied to them and, finally, the double-sided adhesive is glued to the profiles. “
The profiles leave the Alusín Solar factory in Asturias with one side already glued. To ensure perfect fixation, a gluing machine is used to apply a specific pressure. Once the equipment arrives on the site, the roof is cleaned in depth. “This is the most critical process and for this a roller machine is used which cleans under pressure at 225 bar,” Font added. “Then the other side of the profile is glued to the roof covering.” Once the profile is glued, a 25kg roll must be passed over it. In this way, correct adhesion is ensured and the solar panels are installed as with a conventional system.
But the novelty doesn’t stop there, according to Font. “During the assembly process, we installed a series of witnesses, indicators, which will allow us to monitor the system and visualize its aging from year to year to see how it behaves,” he said. for follow-up. “We have… anchorage measurement equipment suitable for this type of test and, with this system, we support the customer throughout the useful life of the installation.
