Rooftop versus Ground mount solar power system maintenance

Man power deployment:

As compared to a rooftop solar power system, a ground-mount solar system is easier to service. This is because a rooftop solar power plant may be scattered across different buildings within the same/different premises and would require greater manpower deployment. For instance, while a 1,000kWp ground-mount solar power plant might only require 4 people for comprehensive maintenance, a rooftop solar power plant scattered across 10 different sites may require 10 people.

Being a premier rooftop solar developer in India, we employ the following methods for a successful solar power system maintenance.


Accessibility on a metal roof is harder than ground mount or RCC roofs. This is taken care of by ensuring proper monkey ladders etc., are available to get onto the roof.

Water source installation:

Installing water connection is more difficult on sheet metal roof as compared to RCC roofs or ground mount system because piping can only be done around the structure otherwise the structure would start leaking.


Safety is a top priority and a key concern for metal roofs. Safety lines and harnesses are deployed at all times when cleaning on metal roofs to avoid any disaster.

Presence of Skylights and HVACs and other structures on roofs:

In the case of metal roofs, the presence of external structures such as skylights, vents, etc., restrict the usage of the roof. Ensuring proper spacing between modules and installing walkways provides room for movement of the cleaning staff and allows better access to individual modules, thus ensuring a better cleaning. This aspect is taken care of during the detailed engineering design preparation by the projects team.

Avoiding business practices disruption:

Extra precautions are taken to prevent damage to roofs, to avoid any disruption of the business processes going on underneath the roofs. This particularly becomes important when the metal roof is actually the only shed to protect the manufacturing/engineering processes beneath.

Analysing the plant performance and sharing DPRs (Detailed Performance Reports)

Our O&M team follows the practice of religiously sending performance reports to our clients every month. A consolidated report about site-read data, Detail Generation Report (DGR) along with shutdown details is compiled every month and shared with the client. The shutdown details are crucial to avoid discrepancies in billing. Good maintenance of the system thus ensures a longer life of the asset.
