Q: Do you need a permit for such minimal square footage, solar panels, water barrel, septic tanks?

We provide a mounting surface for their termination point and a patch-panel to connect them to the internal wiring of the appropriate units.  

A house with a bad old design like that screams that other issues are likely like terrible wiring, an ancient electric panel, aluminum wires, asbestos, lead paint, bad plumbing, and a creepy Norman Bate-style basement.

One client I worked with found a nice house and her "contractor" said she needed a new electric panel and a new air-conditioner and quoted her prices about double what I pay. 

So they had to tear it all out & redo it.In another city/county I upgraded our electrical panel to 200amp & 90% of the old circa 1970's wiring mess.
