To complement the energy generation from the solar panels on their tiled roofs, many property owners also enquire about solar battery storage. Solar batteries help to store the excess energy generated by your panels and make it available at night or when the sun isnt shining. Solar storage is becoming increasingly affordable and accessible with improvements in the amount of energy they can hold and reductions in cost and size. They are easily integrated into an existing system or with a new system.

You spent a lot of money on your tile roof. And now you want solar panels. Obviously, you want to make sure that your new roof will not leak.

The process for installing solar panels on your tile roof sounds scary until you understand some of the realities of how your roof is installed and how far solar mounting products have come.

We always hear about penetrations. There are two kinds of penetrations to a roof.

First, we have traditional penetrations like plumbing vents and air circulation vents. Solar panel installations typically have one of these penetrations per roof surface to get electrical conduit into the attic. This single penetration is the most important because it is a larger hole that must be sealed and flashed to prevent water entry. Flashings are metallic, composite, or plastic parts that shed water away from penetrations. There are many flashings available for this purpose. When done correctly, these penetrations are as good as, and often better than, all of your existing plumbing and ventilation penetrations. Since the quantity is low, the risk is very low.

If your contractor uses any system other than what is described above, they are doing you a disservice. The leader in the industry is Quick Mount PV.

The most visible part of a home solar system is the panels. Around 95% of homeowners choose a roof-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. These rails in turn are attached to mounting points called footings that are bolted into the structural beams of the roof.

Another type that is becoming more popular is a railless mounting system. As the name suggests, railless systems dont have rails onto which the equipment is mounted. Instead, the solar panels are attached directly to footings that are fixed to your roof.

There are pros and cons to both types of mounting systems. While there are aesthetic considerations that might cause a homeowner to ask their installer to choose one type over another, technical demands will usually be the deciding factor. In addition, whether you have shingles, tiles, or metal on a flat or pitched roof will often dictate how your solar panels are mounted to your roof.

How Are Solar Panels Installed On Tiled Roofs

Solar panel installation can be done on many types of roofs, and tiled roofs are the most common kind in Australia. The tiles are stripped and the rafters are screwed to the stainless steel brackets and the tiles are then re-installed in the previous position. The railing systems are mounted on the steel brackets leaving a clear space between the roof and the panel. This allows for air circulation to get between solar panels and tiles and for the air circulation to cool the solar panels in the hot summer months.

The rails and brackets are being used by the solar panel mounting system to connect the solar energy system to the roof frame. The frame weight and the panels are distributed around the covering area. Solar panels are solid, but their weight is relatively light. The overall weight of the tiles, brackets and frames is around 22 kg per square metre of roof area. Australian roof requirements in non-cyclone areas allow for this weight range to be applied to roofs without the need for extra bracing.

A variety of styles and brands of mounting systems are on the market. For the right system appropriate for your roof type, please get in touch with

How Your Tile Roof Stays Waterproof

Whether your tiles are made of clay or concrete, neither of these materials alone will keep the rain out of your house.

While tiles do shed water, both clay and concrete are porous, which means that rain will eventually soak through. In addition, wind can drive water underneath the front lip of the tiles.

This means that the waterproof membrane underneath the tiles, known as underlayment, is the final barrier that keeps your house dry. Itâs these two components working together that make a tile roof so durable. The tiles do most of the work of blocking the sun, wind, and rain, allowing the more delicate underlayment to do its job as a waterproof barrier.

Good installation practices and the use of correct materials are critical for this system to work properly. This is why when you hire a solar installer it is important to ask some key questions.

How To Fix Solar Panels To Tiled Roofing

Pre-Installation Inspection and Measurement

The first step in any good installation process is taking measurements. Remotely or in person, the installers will assess your roof and determine the best place for installation based on the available space, pitch, and orientation. From here, they will take measurements to decide where to fix the brackets and rail system. After the roof has been assessed, the location of the inverter and wiring is also determined.

Removing Tiles

When considering, how are solar panels installed on tile roofs?, the initial stages are a little different to other types of roofs. When the installers first get up on your roof, they will begin to remove specific tiles in preparation for installing the mounting brackets. Based on the measurements and length of railing needed for your solar panels, the installation team will remove tiles so they can access the rafters and roof structure. The installers may also make minor additions to your roof cavity to create additional mounting points for the brackets.

Fitting the Mounting Brackets

Well-practised installers will ensure that the mounting brackets have been thoroughly secured and the roofs waterproofing has not been compromised. If needed, the solar panel installers will also fit flashing and waterproofing material around the newly installed brackets.

Flat Concrete And Rubber Roofs

Some homes are topped with a flat concrete or rubber roof. Fortunately, you can still install a solar panel system safely and effectively on both.

Ballast systems are simply a weighted racking setup that holds solar panels in place.

How Solar Installations Are Done With Different Roof Types

While asphalt shingles are the most common roofing material in the country, many homes have other products such as tile and metal. These materials can make it relatively easy to install solar panels, or make it so difficult that some solar companies will decline working on a project.

For example, its possible to install solar panels on a standing seam metal roof without drilling any holes, making this one of the easiest materials for solar installers to work with.

In contrast, clay tile roofs are so brittle that simply walking on them can crack them. This aspect of clay tiles can increase the cost of installation so much that many solar companies will say that its not worth it for them to take the job. Other types of tile, such as composite and concrete, are more durable and easier to work with. However, they still require special techniques, so a solar installation on any type of tile roof is typically a little more expensive.
