There are several options worth considering when choosing where to mount solar panels. The most popular yet is the rooftop.
That said, some roofs are better suited than others for such an installation. In assessing whether you should mount solar panels on your roof or not, here is a rundown of some of the key things an installer will consider.
Which way does your roof face?
The direction your roof faces is a crucial element that will influence how much power your solar panels will generate. In Australia and other locations in the southern hemisphere, a north-facing roof is ideal.
If this is not the case, your installer can work with what you have. This may include installing a rack designed to orient your solar panels to the north.
What is the state of your roof?
You should take care of any necessary roof repairs before installing the solar panels. This way, you won't have to incur the extra expense of removing the panels, only to put them back onto the roof when you do decide to fix your roof.
The installer can work together with your roofer to identify all problem areas. For severely damaged roofs, you may want to consider a replacement, which has the advantage of ensuring a match between the roof warranty and that of your solar panels.
Is there enough space for the panels?
Your power demands will determine the size of your solar system. The higher your demand, the higher the number of solar panels in your array.
It is always a plus for aesthetics if the solar panels can all fit together in a tidy arrangement. If there isn't enough space, then you may have to consider installing a stand-alone mounting structure for the panels that don't fit on the roof or even all of them.
Can your roof bear the weight?
If the extra weight of the mounted solar panels is more than your roof can handle, you may end up with some significant room damage. In the worst case, your roof may cave in and collapse under the weight. Not only is such an eventuality a danger to your safety, but the cost of roof repair or even replacement will set you back.
As outlined, whether or not your roof is a good fit for solar panel installations comes down to whether it can support the panels and the impact on how much power you can generate.
