These walkthroughs describe evidence gates, not household outcomes. They do not supply a price, savings result, incentive, or payback period. The Solar Savings Calculator remains unavailable until its documented household and source-date inputs are entered, and its owner ledger reports only a whole-year crossover from explicit cash flows.
An owned-system proposal in a high-rate market
A state-average rate can provide comparison context, but it cannot replace the household's annual use, applicable import and export tariff, address-specific production model, same-scope cash price, or source-event dates. Keep the result unavailable until those records support it, then model later owner cash flows in the Solar Payback Ledger.
A battery comparison under net billing
Document the utility's time-varying import prices, export compensation, battery operating assumptions, added equipment price, warranty, and any backup-power requirement. Treat resilience as a separate household objective unless the entered cash-flow ledger assigns it a documented monetary amount. The hardware guide explains why storage and solar production are separate questions.
A renter comparing community solar
Review the subscription price or discount formula, bill-credit calculation, fees, escalation, term, cancellation, transfer, eligibility, and utility territory in the actual agreement. If the applicable tariff or contract schedule is missing, leave expected savings unavailable. The Community Solar hub lists the records to collect.
