Solar Panels On Tile Roof - 4 Factors Before Installation

Are you planning to install solar panels and wondering how to install solar panels on tile roof ? There is no denying the growing popularity and usefulness of solar panels for San Carlos homes. Over the years, manufacturers have produced more efficient and cheaper panels. As we all strive to reduce our carbon footprint, use renewable energy sources and lead a sustainable lifestyle, solar power is the obvious choice.

If your roof is tiled, you may be wondering how you can install and mount solar panels. Don’t worry, Alliedveterans Solar experts are ready to answer all your questions.

Solar Panels on Tile Roof: How Are They Installed?

Solar panels can be installed on many types of roofs using a variety of methods, depending on your roof material and slope. On flat roofs, self-supporting frames are designed and installed to optimize orientation and slope for energy production. L-brackets screw into the existing roof on tin and metal roofs without the need for modification.

On tiled roofs, the most common method is to install mounting brackets on the rafters and use a rail system. While tiles need to be moved, changed, and replaced, the process is less invasive than you might think. Let’s take a look at a detailed breakdown of how to attach solar panels on tile roof.

  • Inspection and Measuring Prior to Installation

The first step in any good installation process is to take measurements. Remotely or in person, installers will assess your roof and determine the best installation location based on available space, slope, and orientation. From there, they will take measurements to decide where to attach the brackets and rail system. After assessing the roof, the location of the inverter and wiring is also determined.

  • Tiles to be Removed

When considering the question How to install solar panels on tile roof ?” the initial steps are slightly different from other types of roofs. When the installers first set foot on your roof, they will begin removing certain tiles in preparation for installing the mounting brackets.

Depending on the size and length of the railing required for your solar panels, the installation team will remove the tiles to gain access to the rafters and roof structure. Installers can also make small additions to the roof cavity to create additional bracket attachment points.

  • Putting the Brackets in Place

After verifying the correct spacing and dimensions, installers will attach stainless steel mounting brackets to the rafters. After fixing the supports, the removed tiles return to their original position. To ensure that the tiles are even and maintain the integrity of the roof, the shingles will be sanded or cut to fit the newly installed supports. Any broken or damaged tiles will be replaced by your installation crew.

Experienced installers will ensure that the mounting brackets are securely fastened and that the roof waterproofing is not compromised. If necessary, solar panel installers will also install waterproofing and sealing materials around the newly installed brackets.

The initial work of removing tiles and mounting brackets is unique to tiled roofs and can result in a slightly more expensive installation process. Each roof is unique in size, shape, orientation, and material. At Alliedveterans Solar, we conduct a thorough remote assessment and provide an honest quote before any work begins. Our meticulous pre-installation process ensures that you enjoy the maximum benefits of your solar system for many years to come. For more information, contact our team today for a solar panel quote.

  • Rail System Installation

Once the brackets are attached, it’s time to install the rail system; Let’s call it a tile roof solar support. Aluminum alloy roof rails are placed on the roof and attached to the brackets; these rails are the attachment point for the solar panels.

Solar Panels on Tiled Roof Materials: How to Install Them

When all the basic work is done, it’s time to install solar panels on the roof. The panels are attached with clips that bolt to the edges of the panels and to metal rails attached to the mounting brackets. These specially designed brackets make it easy to remove and service if necessary to gain access to areas under newly installed panels.

The solar panels are now firmly attached to the roof structure. The total weight of the shingles will be less than 22 kg per square meter, which is in line with roofing regulations. If you live in a hurricane zone, additional reinforcements may be required.

The raised space between the panels and shingles also creates a circulation pocket that keeps the panels cool during the summer months. If you’d like to learn more about how solar panels cool your roof, we’ve put together a detailed guide on how the process works.

  • Putting the Electrics Together

Now that we have answered the question “How are solar panels installed on tile roofs?”, let’s look at some other points regarding the process of installing solar panels on tile roof.

When the panels are installed, the electrical cables at the bottom are connected to each other, forming a “chain”. The “string” is fed under the tiles and through the void in the roof to the inverter.

Installers will not only complete the installation on the roof, but they will also take care of all the wiring and electricity. Once installation is complete, there is no need to access the inverter except for maintenance or data recovery. Most modern systems transmit all data wirelessly to a smartphone app or web platform.

In general, the installation process will only take 1-2 days and will not require major changes to your home. The only work that will require modification is removing and modifying the tiles to install the mounting brackets and create a wiring path to the inverter. Creating a path for wiring is usually achieved by drilling a small, simple hole.

4 Installation Factors to Think About

We have explained in detail how solar panels are suitable for tile roofing materials. However, before proceeding with the installation of solar panels on tile roof, there are several considerations to take into account in order to determine if your roofing materials are suitable for solar panels.

First of all, it is the integrity of your roof. The solar panels will add extra weight to the roof and the solar panel installer will need to evaluate if they can support the panels. Structural integrity can also determine how many panels can be installed, as the larger the system, the more weight it will carry.

Solar panels work best on rooftops with a slope between 10 and 45 degrees. On flatter roofs, specially designed frames or angled brackets may be used to place the panels in the correct position: however, this can also increase installation costs.

Depending on the architecture of your roof, you may have a single slope or multiple edges. Solar panels work best on north-facing rooftops because they receive the most sunlight during the day. East and West orientations are also suitable; however, south-facing roofs are not suitable.

Solar panels depend on direct sunlight to generate solar energy. Before installing a solar system, you need to make sure that your roof receives as much sunlight as possible. If shading can be reduced by removing trees from objects, this is recommended. If it is impossible to avoid shading in certain places, the installer places the panels in the most suitable place.
