Almost all types of roofs can support the installation of solar panels. However, there are certain rooftops that are more affordable to install and efficient in optimising sun exposure.

To help you decide, we’ve prepared a blog that answers the most common questions related to solar and its compatibility with different roof types. We recommend reading through this post, so you’ll know what to expect once you contact a solar electrician.

Can I Install Solar on a Flat Roof?

Yes, you can install a solar PV system on a flat roof. The problem with flat roofs is that they have no angles or slopes readily available for solar panels to benefit from. Improper orientation isn’t ideal since it won’t allow your solar system to maximise its energy output.

The good news is that you can get tilt frames installed on your flat roof so you can take advantage of the best weather for solar panels. These structures allow you to mount solar panels and set them at the appropriate angle to attain maximum sunlight exposure.

At Connected Solar Gippsland, we ensure that our customers with flat roofs have their panels mounted appropriately. Getting tilt frames set up on a flat roof not only provides maximum sun exposure but also helps prevent the buildup of dirt and grime on the panels.

Can I Install Solar on a Tin Roof?

You can install a solar PV system on a tin roof. In fact, many solar electricians find metal roofs great to work on because of their durability.

Solar installers can directly attach the panels to the seams of metal roofs without fuss. This results in a reduced need for equipment and labour, leading to lower overall expenses during installation.

Can I Install Solar on a Tiled Roof? (H2)

Yes, you can install solar panels on a tiled roof. However, choosing to get solar with a tiled roof typically means that the installer will need to take out and replace a few tiles.

The main reason is to set up the racking frame mount to ensure that the solar panels are safe and secure. This is particularly crucial since concrete, clay, and slate tiles in particular can be quite fragile.

Is My Roof Compatible With Solar Panels?

Consider the following to see if your roof is compatible with solar panels:


Roof pitch plays an essential role in solar energy production. Providing the ideal angle for solar panels means that the system can generate energy as efficiently as possible and is safe to be worked on by installers.

Shape and Size

Large rooftops with a square shape are the most compatible with solar panels. The main reason for this is that the shape and size allow for a straightforward installation.

Amount of Shade

The amount of shade on a roof has a direct impact on the efficiency of solar panels. Roofs that aren’t shaded at any time of the day are the most compatible.


North-facing solar panels are the most effective in Australia. It’s also the best angle for solar panels here. This orientation allows a solar PV system to receive the most sunlight throughout the day.

What Roofs Are Not Suitable to Install Solar On?

Roofs that are made of wood and slate aren’t suitable for installing solar on. The biggest reason is that these materials are brittle, making it far more difficult for solar vendors to install a solar PV system.
