You have decided to use solar panels. Now, the next and final step would be to have them installed in your roofs. If you have a sloped roof, then there would be no problems. But if you have a flat roof, you might need to consider using tilt racks to install your solar panels.
Solar panel tilt racks can position your panels at an angle that it receives light the most. Tilt racks can be ballasted or penetrating. Ballasted tilt racks use weights to hold down the panels in place while penetrating tilt racks need to be screwed and penetrates the roofs.
Below are some reasons why you should not lay flat your panels and instead use solar panel tilt racks.
It is easier to clean.
When your panels get dirty due to debris and dust, rainwater is enough to wash them away. But when your panels lay flat in your roofs, water will accumulate on top of it and makes it dirtier because the dust and debris will not be washed away. When the rain stops or water evaporates, you need to remove this dust and debris yourselves.
So to avoid the hassle of cleaning your panels after a rain, you need to install your panels with tilts. In that way, it is appropriately angled where rain can easily wash them clean.
It serves as protection and attachment point for frameless panels.
If you will be using frameless solar panels, it is easier to install the panels on your roofs to a 10-degree angle. Frameless panels have no raised edge so that water can flow smoothly. Without a frame, the tilts can protect the panels’ edges and serve as the point of attachment to the roof.
It keeps the panels secured in place during heavy wind or cyclones.
In Australian regions where cyclones often occur, it is better to install panels using penetrating tilt racks for better attachment. In other areas where it is not cyclone-prone, residents can opt to use ballasted tilt racks that use concretes as weights.
It produces higher electricity output.
When using tilt racks, you can position your panels at an optimal angle where it can generate electricity the most. In various areas in Australia, this optimal angle may differ because of the different amount of sunlight each place receives. Ballasted tilts racks should be angled at 10 degrees while penetrative tilts are tilted with a 15-degree angle when you consider the effects of the wind.
Solar panel tilts are typically installed with some space apart to avoid shading the panels or other racks during winter when shadows are the longest. But if you are using arrays that have panel string optimisation, you can now place the frames next to each other. In this way, panels can still use the sunlight that has otherwise fallen between the rows of the panels, thereby generating more electricity.
It allows solar panels to cool down.
Solar panels in tilt racks have a larger space between it and the roof. Because the panels are tilted, there is more space for the air to circulate behind the panels allowing it cool down. Less heated solar panels can produce slightly more electricity the hotter ones.
