How are solar panels installed on a roof?
The most visible part of a home solar system is the panels. Around 95% of homeowners choose a roof-mounted (rather than ground-mounted) system, so how the panels are attached to the roof is a key detail of the installation. Solar panels are attached to a roof using a mounting system. The most common type is a rail-based system, which uses aluminum rails as the structure onto which the panels and other components, such as wiring and inverter components, are attached.
