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
