As in any power plant , a solar power plant in operation requires maintenance. Also, as the solar power plant becomes older, operation and maintenance (O&M) becomes more and more important for improving or keeping the performance of the plant, and so its revenue.

There are many parameters to be monitored periodically in order to make sure that the PV system is functioning well without any Problem. These parameters include: Inverters,weather station sensors and events.

To keep an eye on every plant operation ,a weekly report is filled. This report values include but not limited to energy production,insolation values , etc… 

The monthly report purpose is to verify weather the plants achieving the required Performance Ratio and Availability that were guaranteed previously.
