A solar panel system installation will bring more affordable energy to your home. But many homeowners are reluctant to take the plunge and install a rooftop solar system on their roof because of various stories involving roof damage. Advances in technology now allows homeowners to access less invasive or non-invasive mounting systems all together.
Popular mounting systems
A roof-mounted solar system is the most common form of a rooftop solar system installation. It’s a very important piece of hardware because it secures the solar panels to the roof. But the last thing you want is for the roof to be damaged because of its invasive installation. Many bad installation stories are told leaving holes in your roof that result in leakage during the rainy season.
However, if you hire a certified solar installer and the roof is in quality condition from the start, you’re likely to avoid any damage or rain leakage all together. This is because a certified installer takes actionable steps to avoid roof damage.
These actionable installation steps include fixing holes with lag bolts, which secure your panels during heavy weather. A flashing, or a metal or plastic shield, fits just under existing roof tiles. The lag bolts and the flashing together are installed to prevent water seepage. If installed correctly, you’re unlikely to have water damage.
But there are two systems on the market that also have very minimal penetration of the roof. These should be your go to mounting systems for a sloped roof solar panel installation.
Rail-less systems are a cost-effective and less-invasive racking system. In a nutshell, they don’t have any rails. These types of systems have less hardware making it easier to handle, install, and ship to the installation site. The ease of installation makes for the reduction in cost. Overall, they’re a great option but the installer has to be certified for rail-less system installations to ensure safety and quality of the system.
Shared-rail systems are the next best step from rail-less systems. They’re slowly emerging on the market, but they basically positively make up for the disadvantages of a typical rail-less system. In this type of system, the rails themselves support the structure of the system and hold the panels in place. A shared-rail system entirely eliminates the need for a standard end and mid clamp system, and it’s considered the next advancement in solar mounting systems.
Rail-less systems and shared-rail systems are two very popular less-invasive solar panels systems for your roof. However, it’s possible to go non-invasive all together. A ground mounted solar panel setup or a community solar network setup, are easy options for not having penetration of your roof at all.
Protecting your roof
A homeowner’s roof is a valuable asset. With new roof installations amounting to more than $10,000 in costs, it makes perfect sense that a poor solar panel installation should make you worry. However, rail-less and shared-rail systems are currently available on the market as the lesser invasion mounting systems available to you. Overall, finding a certified installer is the key factor here, because they ensure that the system is installed well and correctly to prevent rooftop damage. Are you ready to go solar?
