Need advice on drawings

[foo1bar]

i am trying to get all my i dotted and my tees crossed before i submit my permit tomorrow.

1> IMO the plans aren't very readable. I can't tell which lines are dimensions and what are denoting structures/materials.
2> Is there a requirement of 3' on each side of the ridge for fire setback? Throughout CA there is, and I think other places too.
3> The last attachment I am interpretting that as the "rafters" are every 16" OC running horizontal? That'd be really odd.
A> Are you sure it's 16" and not 24" OC? Many roofs are 24" OC - so if you haven't checked, check.
B> Almost always rafters are running with the slope of the roof, not across the slope.
C> I don't see how many attachment points/feet there are - or what is being used (ex. which quickmount product)) I didn't see a "Attachment points every 48 inches" or something similar. (Or are you doing attachment point on every single rafter?)
D> I assume there are multiple microinverters that aren't shown? IMO you need to show them. Do one page per roof face if necessary. Use color or grey fill to make it easy to differentiate between different things.
4> Make explicit the roof pitch - and/or include a photo or non-top-down drawing to show things. (I assume the ridge is between roof 1 and roof 2 - with downslope being to left on roof1 and to right on roof2) An isographic drawing could make that clear.
5> Do you have any vents/chimneys that you need to deal with (dryer vent, plumbing vent, cooking hood vent, bathroom fan vent, HW heater vent/chimney, furnace vent/chimney, etc.) If you're going to have to move them or work around them, put that in your plans.

I think this is a good example plan:

Obviously it'd be better to use as a starting point an example plan from your AHJ if they have one.
But if they don't have an example, I expect your AHJ would be happier with something that looked like that link, rather than what you've attached.

Without a contractor - sure.
Without proper engineering? No.
And what you said is basically that they require an engineer to approve/create the plans - which is not an onerous requirement IMO.
The structural portion you may be able to get enough from Ironridge and Quickmount.
The electrical portion you may be able to get enough documentation from Enphase since you're using them. That might be enough to make your AHJ happy. (And if not, it's probably less than $300 to get a plan written for you by someone. A vendor selling you panels, etc might even toss it in as a "free with purchase")

Sorry, i could not edit my post

Edit: Main panel will have a double pole 20 A breaker based on the micro inverters amperage

I think you may be in over your head. Good luck.

sensij, thanks for the quick reply, i spoke with my AHJ or the electrical inspector in my town, and i was told that he will reject
my permit if its the drawing is not done by a PE or electrical engineering firm!!! i am kinda furious about this, so i am trying to get all my i dotted and my tees crossed
before i submit my permit tomorrow.

Like'em or not, two rules that need to be followed: Rule #1: The inspector is always right. Rule #2, if the inspector is wrong, see rule #1.............................. FWIW, a couple of things I didn't see on your drawings was any reference to wind or seismic loading considerations, or any bolting/screw/fastener details........................................... . Also, sometimes/usually it helps to go to the AHJ before submittal. Often, believe it or not, building depts. can be quite helpful. One big reason they are there is to help ensure safety for not only you, but your neighbors and the rest of the community. They are not out to get you. They have better things to do............................................. You can do pretty much what you want to your property without a contractor's assistance, but only to the extent that what you do follows safe, recognized and allowable practices and applicable building and other codes.

Enphase micro inverter M250 requires a 20 A breaker for every 16 inverter per string/branch.

I am using 2 strings of 9 panels/micro inverters, so 2 20 A per Enphase manual

I cant post link, but just google M250-LL2-60-S22

I think you may be under-estimating the knowledge required to safely design and install a PV system. Looking just a bit closer, I think you'll find that the 20 A PV breaker you specified for the main panel is undersized... what calculation did you use?

It depends on what your AHJ wants to see. You could be including more of the electrical calculations that show compliance to the NEC requirements you've considered. Also, grounding strategy should probably be included. Sometimes, fire rating is important as well. Have you tried asking your city for an example to follow?

Hello everyone,
I'll be installing a solar panel system on my roof, but 1st i have to apply for permit.
Here are few pics of my solar panel system drawing proposal for the town.

If anyone has any suggestion or correction that needs to be done PLEASE dont hesitate to mention it.
no matter how serious or silly it is., i need to get this perfect, so i dont have no issue with my town inspector.

Thanks
