Self install grid tied
I live in Phoenix I'm on APS I have been watching solar system kits come down in price to a level that I can actually afford now. I'm very interested in doing the install myself for a number of reasons looks like I can get a grid tied micro inverter 4.9KW DIY UL approved kit for around $8400 before fed and state rebates. I contacted APS about doing a self install they sent me a link to a website that had all kinds of information and requirements that had to be approved, but as far as I could tell if the city issues me a permit, and they sign off on the inspection APS will allow me to connect after they have approved the design as well APS incentive is only .10 so not worth having years to payback a loan that went into the contractors pocket some I have seen as high as 15k install fees. It looks like to me the city allows systems that are lighter then 5 SPF to go on the roof without a structural engineer signing off on it. I did some checking a panels were coming in at around 2.2 SPF. I have an electronics background, and have done a lot of my own electrical projects in the past. Is there any other hidden fees that I have to worry about the city seems to have some high fees for solar installs around $600 I haven't called them to confirm. I could not find any requirements that said I had to get a contractor to connect it only that I had to get the city to sign off on it.
