Many users of the residence in the renovation of the choice of the metal roof, and now see others have installed solar panels on the roof, they also want to install a solar panel. However, considering the fact that they have a metal roof, they are afraid to install them easily. Do you want to know about installing solar panels on metal solar roofs? Let’s take a look.
Can I install solar panels on a metal roof?
Yes, you can. The current market research found that metal roofs can generally be divided into three categories: upright seam metal roofs, metal tile roofs and corrugated metal roofs. But no matter which type of metal roof, solar panels can be installed.
1. Standing seam metal roofs: Installers can be found to install solar panels directly into the seams between roofs using a mounting system. Time can also be saved as a result.
2. Metal Tile Roofs: same as regular tile roofs, one can purchase tile replacement brackets in the market and use them to replace some of the original tiles on the roof and then install the solar panels after.
3. Corrugated Metal Roofs: Compared to the first two types of roofs, the installation of solar panels on these roofs is a bit more complicated. Due to the difference in structure, this type of metal roof requires drilling holes to fix the bracket if you want to install solar panels. Therefore, this kind of metal roof must pay attention to the waterproof work, but can be bonded to the metal panel instead of drilling holes.
2. What are the advantages of installing solar cells on metal roofs.
Long lifespan: Metal roofs have a much longer service life than traditional tile and brick roofs. The warranty on solar panels is usually around thirty years, whereas traditional tile and brick roofs generally last less than thirty years, which means that when you replace your roof, the solar panels will still be under warranty and you will lose the remainder of the warranty. Metal roofs, on the other hand, usually last longer than thirty years, which prevents this from happening.
3. What should I be aware of when installing solar panels on a metal roof?
1. From a chemical point of view, metal roofs are mainly made of steel, iron and other metals. This means that when we install solar panels, the choice of metal bracket must pay attention to its materiais. Must not form a primary cell with the roof to avoid damage to the roof, the current market generally use aluminium bracket. Because aluminium leakage in the air will form a protective role of aluminium oxide film, in order to prevent the formation of primary cells. (Brass brackets can also be used)
2. Although the distribution of electrical wires on metal roofs is generally the same as on ordinary roofs when installing solar panels, it is still necessary to pay attention to avoiding direct contact of electrical wires with metal roofs.
4. Is the cost of installing solar panels on a metal roof higher?
Generally speaking, there is not much difference (depending on the cost quoted by the installer). Like most common tile roofs, metal roofs are also installed with aluminium mounts. The labor cost may be a little higher because the installer has to pay more attention to the details of planning the distribution of wires, but overall, the cost difference is not significant.
Summary
In conclusion, it can be said that the advantages of installing solar panels on metal roofs outweigh the disadvantages. However, whether to install solar panels on metal roofs or not is still a matter of weighing the pros and cons on your own.
