1. What factors (partial shading, multiple orientations, rapid shutdown requirements, plans for incremental additions later, etc.) do you see as making a string inverter uneconomical in your situation?we have a very good design for sealing each point of entry but thank you for the concern, and as in an above reply, a string inverter is too uneconomical to consider for our particular system.
2. I have, in the past, not heard many good things about thin film systems (efficiency, longevity among other things.) Have there been qualitative improvements recently?
