Many homeowners and building owners wish to switch to solar energy. However, can a rooftop solar power system (PLTS) still be installed if the roof is damaged or leaking?
Answer: Damaged Roofs Are Not Suitable for Solar Installations!
The answer is: installing a solar power system is not recommended until the roof has been repaired.
Installing a rooftop solar system requires a supporting structure that is sturdy and durable.
Risks of Installing Solar Systems on Damaged Roofs
Forcing the installation of solar panels onto a roof with physical damage carries several serious risks:
1. Risk of Worsening Leaks
The solar installation process requires mounting systems, which often involve drilling. If the roof is already fragile, the surrounding structure may crack, exacerbating leaks during rainfall.
2. Risk of Damage to Solar System Components
Rainwater seeping or dripping onto the cabling and electrical components beneath the panels can trigger short circuits or damage the equipment.
3. Additional Load on the Roof Structure
Solar panel arrays and their supporting structures are heavy. Roofs with rotted wood or steel are at risk of sagging or collapsing because they cannot bear the weight. Ultimately, this could lead to workplace accidents involving both the client and the vendor.
4. High Costs for Removal and Reinstallation
If you install the solar system first and decide to repair the roof later, you will incur additional costs for dismantling and reinstalling the solar panels.
5. Installation Safety Concerns
From an HSE (Health, Safety, and Environment) perspective, a damaged roof is unsafe for technicians. There is a risk of workplace accidents if installation is attempted on a damaged roof.
Essential Steps Before Installing a Solar PV System
To ensure your green energy investment is secure and lasts for 20–25 years, take the following preparatory steps:
1. Roof Feasibility Inspection
Have a solar PV technician or a builder inspect the structural integrity of the roof frame and roofing materials.
2. Repair or Replace Roofing Materials
Fix roof leaks, replace broken tiles, or upgrade wooden or lightweight steel frames that are no longer in good condition.
3. Choose a Suitable Mounting System
Use high-quality panel mounts with waterproof sealant applied at every drilling point.
4. Hire a Professional Solar PV Installer
Ensure the installation is performed by a certified team to guarantee structural safety and proper electrical wiring. Batari Energy is an example of a solar PV installation provider that meets these standards.
Repair Your Roof Before Solar PV Installation
Repairing the roof beforehand may increase initial costs, but it is far more cost-effective and safer than dealing with major damage later on. Ensure your roof is in good condition before you start enjoying the electricity savings provided by solar power.
