How to install the solar photovoltaic mounting structures on the  roof

As there are so many types of roofs, there are many different requirements for installing solar panels on the roof. In metal roofing materials alone, there are various contours, specifications, metal types, and factors to be considered for the correct installation of solar panels.


This is why it is very important to cooperate with a trusted solar installer who can confidently choose the right mounting bracket for your metal roof solar installation.


Good combination of metal roof and solar panels

Metal roofs are very suitable for solar energy because they can last a long time. If it is time to replace the roof before replacing the solar roof, you can also consider investing in the installation of a metal roof.


Metal roofs can last up to 70 years, while asphalt composite shingles are expected to last only 15-20 years. Most solar panel installations can be guaranteed for 25 years, but the system will be produced with a strong capacity far exceeding this.


When it is time to invest in a new panel (for example, 30-35 years from now), you can simply replace the panel without installing brackets and slide rails. If you plan to stay at home for a long time, this may save you a lot of time and money.


Install solar energy on an upright seamed metal roof

If you are lucky enough to have a metal vertical seam roof, you can clip it to the seam using a solar panel mounting system. In this way, there is no need to drill holes in the roof. Your solar installation will be faster, less labor, and you don't have to worry about roof penetration and water ingress.



The clamp is made of high-strength aluminum, and a single bolt is used to fix the clamp. Most have a warranty of at least 10 years, but it should be easy to extend the life of the solar system.


Solar roof installation with corrugated metal roof

If you use a corrugated metal roof, you need to use another installation system. A special bracket is attached to the top of the corrugation to make the lower drainage area without holes.


The high-quality bracket will have a rubber gasket seal on the base, so your installer does not need to worry about using messy sealant all over the roof.


Solar panel system for installation on a trapezoidal metal roof



Trapezoidal roofs usually have more flat areas between each peak, and the height of each ridge can vary. In this way, the shape of the bracket used for the trapezoidal metal roof is also different.


Their installation principle is similar to that of corrugated metal brackets. The idea is to make each bracket close to each trapezoidal ridge to ensure that the best drilling location is above the bottom of the roof. In any case, the standard practice for this type of roof is to use a sealant to ensure that there are no leaks.
