The BASIC MAINTENANCE OF THE SOLAR PV SYSTEM. 12012(0)

Performance of solar rooftop PV system with regular & basic maintenance improves. For best system performance, regular maintenance is necessary. This leads to increased system life and decrease in disruptions due to component failures. 

One of the most important job is to clean the solar panels regularly. During the cleaning, panels need to be washed with the help of a hose pipe to remove the dust and dirt on the surface of the panel. This enhances power generation. 

Incase of dense or stubborn layers of dirt, modules need cleaning with a sponge or soft cloth or glass wiper after spraying some water. Glass layer needs to be wiped gently to avoid cracks due to small stone particles in the dust.  Even the bird droppings need a similar treatment. It helps decrease the effort to clean and at the same time removes the bird droppings completely. 

More importantly, the ideal time to clean panels is before 8 AM or after 5 PM. It avoids the microcracks on the module glass surface.

It is also suggested to remove the dry leaves if any to avoid long term problems like water clogging, short circuit due to moisture and fungus etc.PS: Since, modules are placed on the rooftop, it is very important to have safe walkways for the cleaning of the modules. Incase of a complicated rooftop, it is highly recommended to use a safety harness before considering cleaning the modules.
