    14. Can you provide a detailed breakdown of the costs involved in the installation, including any potential additional fees?
    15. What post-installation support and customer service do you provide?

    If you are opting for more aesthetically pleasing and multipurpose installation such as a hut or covered area with elevated structure. 

    You must ask your installer if the structure that is being built is properly designed by engineer to withstand various loads during its lifetime. What material is being used for installation. Given that most guidelines insist upon mounting structure of HDGI (Hot Dipped Galvanized Iron) so as to prevent corrosion and lighter weight of the structure. Generally speaking, total weight of such structure should not exceed 60-70 kg per meter square. Any solar structure and panel installed on your roof is going to last for more than 20 years, which is a very long period. Steps need to be taken at the time of installation itself to ensure longevity of that structure. 

    Various other aspects also need to be kept in mind such as change in energy needs, scope of expansion, ease of replacement etc.

    What are the different mounting systems for rooftop solar systems, is it damaging to the roof?

    by with 5 Comments Blog

    There are several types of mounting systems used for rooftop solar installations, each with its own characteristics and suitability for different roof types and conditions. The most common mounting systems include:

    • Railed Mounting Systems: Railed mounting systems consist of aluminum rails that are attached to the roof structure using lag bolts or roof attachments. Solar panels are then mounted onto the rails using clamps. Railed systems are versatile and can be adjusted to accommodate various roof angles and orientations.

    • Rail-less Mounting Systems: Rail-less mounting systems eliminate the need for aluminum rails by attaching solar panels directly to mounting feet that are anchored to the roof. This design reduces material costs and simplifies installation, but it may be less adjustable than railed systems.

    • Ballasted Mounting Systems: Ballasted mounting systems are commonly used for flat roofs where penetrating the roof membrane is not desirable. These systems rely on weighted ballasts to hold the solar panels in place, reducing the need for roof penetrations. Ballasted systems are relatively easy to install and can be removed without causing damage to the roof.

    • Tile Roof Mounting Systems: Tile roof mounting systems are specifically designed for roofs with clay or concrete tiles. These systems use brackets and hooks that are compatible with the shape and dimensions of the roof tiles, allowing for secure attachment of solar panels without compromising the integrity of the roof.

    • Low-profile Mounting Systems: Low-profile mounting systems are designed to minimize the height of the solar array above the roof surface. These systems are ideal for aesthetics-conscious homeowners or situations where space is limited.

    Regarding potential damage to the roof, proper installation by trained professionals minimizes the risk of roof damage during and after the installation process. However, there are a few considerations to keep in mind:

    • Roof Penetrations: Most mounting systems require roof penetrations to secure the solar panels in place. When installed correctly and sealed properly, these penetrations should not cause leaks or damage to the roof.

    • Weight Load: Solar panels add additional weight to the roof structure, which must be accounted for during installation. The mounting system should be designed to distribute the weight evenly and prevent undue stress on specific areas of the roof.

    • Proper Installation: Hiring reputable and experienced solar installers ensures that the mounting system is installed correctly and in accordance with manufacturer specifications and local building codes. Improper installation can lead to roof damage and void warranties.

    In summary, while rooftop solar installations involve some level of penetration and added weight, proper installation techniques and suitable mounting systems help mitigate the risk of damage to the roof. Homeowners should work with professional installers who can assess their roof's condition and recommend the most appropriate mounting system for their specific needs.
