Right? The idea of claiming a tax credit on non-solar roof tiles is so obviously against the spirit and intent (and also to my reading, the terms) of the ITC that it kinda amazes me how far people will go to contort their reasoning and feel justified in what’s basically fraud.
Taking things to the logical extreme, let’s say I install a 1kw solar roof on my 10,000 square foot mansion. The idea that the government should reimburse me 26% for my entire roof is absurd.
Jrweiss is correct about one thing, it will take some publicized audits and decision memos from the IRS to make things crystal clear given this emerging market of products. Though I have to think that claiming a 6 figure ITC will no doubt raise audit flags and provide the government with their sacrificial lamb soon enough.
I agree, typically only the portion that is strictly generating renewable electricity was supposed to be eligible for the ITC. The grey area comes in to play that the costs to enable the renewable energy project are also eligible for the ITC. This includes code compliance (eg disconnects and permitting), wiring, racking, flashing, direct labor costs, the installer's overhead, etc.
So, just playing devil's advocate for a second... if a homeowner needs to get a new main service panel (MSP) to have their new solar + ESS functional per code, would you consider that marginal cost of the MSP to be a green/solar equipment and therefore that cost is eligible for the ITC?
If the answer is "yes, the MSP is part of the solar project"*.... then is it that big of a stretch for someone to rationalize that the entire roof replacement (regardless of active tiles or not) is enabling the solar generation project? After all, you cannot simply install the active tiles of a Tesla Solar Roof without all the other bits.
If the answer is "no, the MSP is not part of the solar array".... then all solar-customers would need their solar installers to provide an itemized invoice or bill of material isolating the costs of items like a MSP, breakers, gutter boxes, disconnects, etc. So the homeowner doesn't claim a 26% on the items they feel do not actively generate power.
If the answer is "it depends" then who becomes the arbiter to determine each unique case? Shouldn't homeowners simply claim the most possible from their own point of view, and have the IRS come back with their own assessment if the IRS deems the homeowner is incorrectly claiming value under the renewables ITC?
* PS: if a homeowner believes the MSP is part of the solar project to be eligible for the ITC, then PG&E could be technically correct that their like-for-like provision for safety clearance to a gas riser will not apply towards the MSP. Because then the MSP is part of the solar project, and could mean the main service panel is not part of like-for-like.
