Despite the fact that solar panels generate electricity using sunlight which is a never-ending and ultimate source, we shouldn’t deny the fact that panels aren’t enough to get the job done. There are certain factors that must be taken care of in order for your panels to work efficiently as a result of which you will get electricity for your household usage as well as for your workplace. The tilt angle of the panels along with their orientation are two of the most important things in this regard. If you’re living in Australia and your solar system is connected to the grid, the panels will be installed at a certain angle in order for the panels to generate more power.

But what are the available options for you if the roof of your house is flat? Is it a good idea to install the panels in a horizontal direction? Let’s take a look at this.

Should You Tilt Your Panels on a Flat Roof or Not?

If the panels are installed at a suitable orientation and at an ideal tilt angle, don’t worry about their efficiency because that’s the only way to get maximum power output from them. In Australia, the perfect ...
... direction for the panels is North and the required tilt angle for them to work well is 30 degrees. Nowadays, manufacturers are providing warranties for the panels that they will work on flat roofs as well. But that isn’t the only thing we want from the panels. We want them to self-clean themselves as well in case of rain or something like that which is possible only if they are tilted. It also depends upon the roof as well.
If the roof of your house is completely flat, there are very rare chances that the panels will generate power unless it’s midday and the sun is present just above the panels. In any other case, panels will not work well. In such circumstances, there may be a possibility that you install tilt frames but that will increase the cost of the entire Solar System Setup which is not affordable in most cases. So, take a closer look at all the factors before installing panels on a flat roof.

How dust gets accumulated on flat solar panel arrays?

Self-cleaning of the panels is a necessary thing that is only available in tilted panels. If they are horizontally placed, dust will keep on accumulating which will ultimately cause the panels to generate lesser power. So, self-cleaning has the utmost importance in increasing the efficiency of solar panels as well which is why they must be installed at a certain angle and orientation.
