Reviews & Questions

Questions (3)

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

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