The panels are currently functioning properly; I have an 8 KW system with 5 Kw of feed-in power. I have panels on three sides, East, North, and West. It's a good system, and I'm satisfied with it so far. wishing it will continue to function flawlessly for many years. I still think the system will maintain its lead, even with a chilly winter and impending price increases.

We are quite happy that we chose an East/West layout for our roof because they produce pretty early in the morning and continue till late into the evening. a great deal longer than our old system. Also want to thank A1 for excellent work

Will the company replace the panels after 30 years if the efficiency is worse than promised?

Yes, we deliver all our equipment to Nevada.
Do I need a mirror to use the other side of the panels?

Mirror is not a necessity to benefit from bifacial panels, but theoretically it could further boost the performance.
