Concrete Tile Solar Roofs

Our methodology for Concrete Tile is the same for light Spanish Tile:

  • Remove the Concrete Tiles above the rafters
  • Install and waterproof the solar mount
  • Drill a hole in the Concrete tile
  • Replace the Concete Tile
  • Screw riser thru the hole to the solar mount
  • Mount the rails and then the solar panels
Removing the Concrete Tiles

Clean installs are a key success factor for ABC Solar. We pride ourselves on designing and installing solar electric systems that look great.

Mounting feet are the primary component of a roof top solar installation. The feet are installed by a licensed roofer on all of our retrofit solar installations. The feet are mounted to house a solar rail which will then house the solar electric panels. The feet allow 2' of over run on the ends and 4' to 6' for the entire row span.


We use standard roofing penetration waterproofing materials, which includes "Henry's" and tacky tape. We guarantee our installations for 10 years so we focus on 100% waterproofing. This is the most important part of our job.

Feeder Drill Holes

Once the rafters and the layout of the feet are determined we will drill feeder holes to make bolting the feet to the rafter smooter, safer and stronger. 5/16" by 3" lag screws are used per mounnting foot.

Solar Rails Attach to Solar Mounts

The solar rails are laid along the solar mounts to check for distance. The number of solar panels is calculated by width or height depending on if your installation is portrait or landscape. For example, we consider the Mitsubishi Solar 185 watt panel to be 33" by 66", which is slightly bigger than their actual size to account for mounting parts.

The rails are then drilled above each solar mount and then attached with washer and bolt.

Solar Panels are Attached to the Rails

The key thing to remember about the solar panel mounting system is the solar panels are about 4 inches above the surface of the roof. This provides that solar panels with the ability to cool down. It also has the effect of providing a shade barrier for your roof. Yes, the solar panels will make energy and keep your home cooler.
