One question first. Are you renting this appartment or do you own the complex. I worked for a property management company for years and this would have never been approved for a tennant. I was the head of maintenance and without an agreement me or one of my guys would have gone up, snipped the wire and took your panels, evict you, and then sued you for the damage to the roof.
Just wondering,

Need help with solar panel array design for apartment building
I am in process of designing a solar panel array for a flat roof apartment building in New Britain, CT. This is my first solar panel array install. I based my design partially on another design that a friend of mine had installed. I already have my inverter, wiring, dc disconnect, ac disconnect, conduit, combiner box. I haven't purchased the panels or mounting system yet as I don't want to purchase until I have gotten some feedback on my design. I used the sunnyboy design tool to help me figure out # of panels, strings, etc. I want my design to be able to accomodate future expansion without having to change out combiner box, disconnects, etc. I might be ok with swapping out my inverter in future if I need a larger one.
Anyway, could you all take a look at the attached design and let me know of any feedback you have.
Specific questions are:
1. is the 15 amp fuse in combiner box sufficient
2. is my 8 gauge wiring sufficient
3. are my ac and dc disconnects appropriate for the system
4. what size fuse should I use in my ac disconnect
5. what size breaker should I use in my electric service panel
6. Is there anything missing from my system
7. are there any mistakes in my design
