Roostre,

"Ok, I think that an 11 x 3 grid would work and look the best for this roof. Using this I get 8.75kW system and the cost is much lower, which gives me some room to pay for engineering plans, my electrician and possibly some labor help. Also, the power company states that no disconnect is needed on systems under 10kWh."

Does your utility require an engineering plan by a licensed PE engineer? Usually, this is just a plan of the system. I do like to put in a disconnect for safety reasons. These are not expensive (<$100).

Also look at panel installation in the landscape orientation. Sometimes this just "fits" better on the roof.
