Dear,
Welcome to Solar Community. Hope you will continue to share your solar knowledge with us. I love reading your posts on solar. Looking at your solar graph I understand that your solar plant efficiency is very good. However, solar panels lose some efficiency day by day. You mentioned it's time for solar maintenance. I have opened the links to your previous posts. The efficiency of your solar panel is very good.

I look forward to reading your next post. Good luck to you.
