Solar Tiles
Solex solar tiles must be installed as an area surrounded by compatible concrete tiles – Marley Modern or Redland Mini-stonewold.



 Twin 2x 5m2 solar tile installation for solar water heating
  Virtually unbreakable polycarbonate solar tiles
The tiles are made of transparent polycarbonate plastic, which is extremely tough and weather resistant.
Installation
The tiles are installed on a conventional roof construction, typically consisting of rafters with a breathable membrane over, with or without sarking boards or insulation to suit the design.

Vertical counterbattens and horizontal battens, both 25 x 50mm, are fitted over the membrane.

The solar absorbers, which lie under the tiles, are fitted together over the battens with metal 10mm connectors. The ends of the courses are linked with loops of 10mm copper pipe.

The solar collecting area is tiled with the transparent solar tiles, and is surrounded on all sides by concrete tiles laid in the normal manner.

Each solar tile is securely held down with two nails holding the head of the tile to the batten, while the lower corners are held against windlift by means of a nail one side and a lug locking into the adjacent tile on the other.

The visual effect of the tiles is a uniform medium to light grey, a combination of the reflection from the surface and the black colour of the absorbers panels which lie beneath them. Planning authorities have welcomed these roofs as a more aesthetically pleasing alternative to solar panels.
