Tata Power Solar — Solar panel problem

Address:

sheela sadanam , Monippally, Kerala,

I have installed an on-grid solar panel 3kb in 2018 by unique energy kottayam. This is the 8th time it has not working properly. First 3 times the engineer said the problem with the inverter and it was changed last three times. But the problem still exit. Then the engineer said it is the problem with earthing. They have changed earthing in april 2020. However, the system is not working as it should be. Then they said it is problem with the invertor and installed a new one in 4months ago. Now the solar panel is not working again. Informed to the office but no one arrived to check. I want to know why this is keep on happening? We need to know the exat problem. Someone who knows should come and check it rather than sending a technician to solve the visible problem. Please send someone to find the cause why my solar always create problems. I believe the products are not meeting the quality. So I'm very disappointed with this. I would like you to consider this and please do the needful as early as possible.
