Between rainwater and solar power, the rooftop is limited

Realistic synthesis
The people, events, figures, and contract terms are a synthetic premise. They are not statements of real cases or of current law. The source documents are the roots of the background and the norms and do not establish the premises of the scenario.
The question to decide
Because of load limits and layout constraints on the rooftop, rainwater storage and solar panels cannot both be installed at the scales originally planned. Water and power demand change with the seasons, and installing both at reduced scale raises per-unit maintenance and management burden. How much of each function should this rooftop secure?

The situation as it stands
In the synthetic design, load and layout constraints prevent installing both facilities at their planned scale. Decision deadline: within 45 days, before the rooftop remodeling contract.
2026 synthetic scenario · Sharing a roof between rainwater collection and solar panels. The people, organizations, figures, and events are fictional.
- Premise 1In the synthetic design, load and layout constraints prevent installing both facilities at their planned scale.
- Premise 2The building's water and power demand differ by season, and water storage requires verification of quality and maintenance conditions.
- Premise 3Reducing both and running them in parallel keeps both, but at smaller scale, raising per-unit maintenance costs and management complexity.
Where it holdsRooftop area, load capacity, and water and power self-supply functions
What is still unknown
- Unknown 1Water and power demand by hour and the actual scope of substitution
- Unknown 2The verified load and maintenance conditions of each facility
- Unknown 3The resources available to substitute when one of the two stops
Signals to decide again
- Define the observations, responsible parties, and check windows for confirming "water and power demand by hour and the actual scope of substitution," and re-judge if new confirmations change the tradeoffs of the options.

Where the paths partNot answers — paths that part from the same starting point
The building's use plan changed, reducing daytime power demand and increasing water use.
A structural inspection found that the area available for storage facilities became even narrower.
