> I'm very confused on how the extra $100 would meaningfully affect the project in either time or BOM. reply That one change was the tip of a very large iceberg. They easily added somewhere in the order of $50K+ to the total cost of the system. I could have installed triple the power generation capacity for that money. BTW, I did the bulk of the work on this installation myself (with the help of my kids here and there). No general contractor involved. Had there been a contractor on the job the cost would have been far greater. Before someone jumps in and says "You probably screwed-up the design" (after all, this is HN). I designed the entire system, hired a civil engineering firm to review the design and calculations as well as provide stamped blueprints and calculations (you can't get a permit unless you have this). I also consulted with the same plan checkers throughout the design process (before hiring the civil engineering firm) as well as with my suppliers and buddies who had built similar systems. I only hired the civil engineering firm one the plan checkers told me verbally that all looked good and I should move forward, hire the engineering firm and submit the drawings and calculations for official approval and issuance of permit. I got verbal "All is good" from the structural, electrical, planing/zoning and fire plan checkers. Three days after I submitted everything for approval the very same plan checker who told me all looked good rejected the very same plans he and I had discussed during weekly meetings for about two months. Things got surreal from there. I spoke to multiple contractors from different trades during my many visits to the plan check office. I did not find one who did not have horror stories --multiple horror stories-- about dealing with these people. Anyhow, it's a somewhat distant memory now.
