Install solar tiles on the roof of the villa

Solar panels can be installed on a tiled roof in three ways: by installing solar tiles directly onto the roof or by attaching panels using mounting brackets. Most people install solar systems on their existing houses ('retrofit') using this method.

The best way to install solar panels on a lightweight tile roof is through a method called inset solar installation, also known as a “comp-out” installation. This technique removes the section of tile where the solar panels will be installed and replaces it with composite shingles before mounting the solar array.

For battens of other sizes or sarked roofs, alternative kits are also available. Begin by installing the first solar roof panel in the array - this should be the one located on the bottom left. Work up each column, then move to the right. The tiles can be installed in either landscape or portrait orientation using the same method.

Future damage from vibrations: Even if tiles remain intact during installation, they can weaken over time. Wind moving between the solar panels and the racking system can create vibrations that cause tiles to crack down the road. Because of these risks, standard installation methods won't work for tile roofs —especially lightweight ones.

If installers attempt to mount solar panels directly onto lightweight tiles, several issues can arise: Tile breakage: Walking on or drilling through these tiles can cause cracks or breaks, which may lead to roof leaks and structural damage.

By removing tiles and installing composite shingles underneath the solar panels, this method eliminates the risk of cracking tiles during installation or in the future. It also prevents damage to the underlayment, which is critical for waterproofing.
