How do partial-coverage designs (mix of PV and non-PV tiles) affect ROI vs conventional racked PV—what’s the breakeven by utility rate and roof geometry?

Partial-coverage Tesla Solar Roofs (a mix of PV and non-PV tiles) usually have a lower ROI than conventional racked solar panels, because:
• You pay for the **entire solar roof aesthetic**, not just power generation.
• Non-PV tiles add to cost **without producing energy**.
• The ROI depends heavily on **roof geometry** and **local utility rates**.
Insightful topic and really interesting read
If you’re just swapping out your roof and dig the sleek look of integrated solar, the Solar Roof could be a neat choice, even if it doesn’t cover the whole thing.
But hey, if you’re all about saving as much money as possible on energy costs, going with regular solar panels will probably get you your money back quicker.
