If you look into solar panels you'll notice that the majority of sellers boast that the panels come "maintenance cost-free". Since there are no moving parts, the wear and tear are lower. This is why the majority of manufacturers tend to emphasize this feature. The truth is that a solar panel once installed lasts from twenty to twenty-five years. Here we discuss solar panel maintenance.

In the beginning, take note of the solar panel's cleaning. As time passes dirt, dust pollen and other particles begin to accumulate on the panels which prevent sun rays from being able from entering the PV system.

Since sun rays aren't completely absorbent by the panels the energy produced from the solar panels is likely to decrease in time. This could impact your monthly savings from solar. Therefore, it's a good idea to wash the panel by spraying it with water using the Hosepipe. 

Take note of any internal problems such as faulty panels, glitchy wiring systems, and substandard inverters which reduce the efficiency of the panel. To ensure that these issues are addressed, you should hire experts that offer local solar panel cleaning. 

There is no way to prevent natural catastrophes. The solar panel could be damaged by hail storms or hurricanes, tree limbs falling over them and the list goes on. This kind of damage usually is not covered under warranty. You can even search online for more information about solar panel maintenance.
