Su-Kam — sukam solar panels have reduced to 1/3 current in just two years while the company has given 25 years warranty of panels

In the month of 2016, 500 w sukam solar panels were installed. Warranty of 25 years was given by sukam. But the current is reduced to only 4a per panel which was promised to be 12a. We informed the distributor about this issue, but the distributor informed us that su-kam has closed its business. We tried to contact at su-kam customer care number. But there is no response.
In only 3 years has passed, when services under warranty are required but sukam is not providing the same. We even tried contact su-kam through its website but the website is also disabled. As such we have left with no option except raising this complaint.
Kindly take necessary action to redress my grievance regarding su-kam solar penal warranty and repairing issue
