Generally, the utilization of a monitoring app provided by the solar system installer can help you notably keep track of the amount of energy that your solar panels are able to produce. In case you notice a significant dip in the production levels, you can try cleaning your solar panels a bit and check for wirings if you are using more than one panel.
One of the best solar EPC companies in Gurgaon, Evaska Energy, offers a warranty of 25 years for the solar systems they provide, so you need not worry if anything goes wrong with your solar system. The only time you will need to worry a bit about the maintenance part of the solar system installed on your rooftop is when your area receives heavy snowfall, as it can severely hinder the performance of the solar panels.
