HOMEOWNER QUOTE REVIEW / SELF-SERVICE WORKBOOK
Put up to three solar proposals on the same evidence ledger.
Compare quoted cost, financing, production assumptions, scope, warranties, batteries, and dated incentive evidence without an automatic winner.
$59 controlled commercial test. English-language digital delivery.
No automatic 30% federal credit enters a 2026 proposal.
Current IRS guidance says Section 25D is not available for expenditures after December 31, 2025. The workbook fixes the current 2026 control at EXCLUDED and $0. It does not determine individual tax eligibility.
DOCUMENT -> EVIDENCE -> STATE -> QUESTION
One continuous review trail
The workbook separates document capture, evidence status, arithmetic, and professional follow-up so an empty field never becomes a favorable zero.- 01
Transcribe
Enter the exact proposal version, date, scope, equipment, production claim, price, and source reference.
- 02
Separate
Keep cash, loan, lease, and PPA obligations distinct. A low monthly payment is not treated as a low total cost.
- 03
Verify
Attach the administering authority, official URL, checked date, status, payout year, and quoted-price treatment for each incentive.
- 04
Resolve
Carry INCOMPLETE, UNKNOWN, CONFLICT, STALE, and NOT DIRECTLY COMPARABLE states into an installer or adviser question brief.
What becomes comparable - and what deliberately does not
| Ledger | What it exposes | Stop state |
|---|---|---|
| Proposal evidence | Exact document, date, expiry, scope, models, production source | INCOMPLETE when a required fact is missing |
| Purchase price | All-in contracted-scope $/W | PV-only $/W stays UNKNOWN unless PV price is itemized |
| Financing | Upfront cash, principal, note rate, APR, term, disclosed fees, payment schedule | Cash/finance spread is not labeled a dealer fee without contract evidence |
| Lease or PPA | Scheduled nominal payments, escalator, transfer and end-of-term terms | NOT DIRECTLY COMPARABLE to ownership payback |
| Incentives | Confirmed official evidence with payout timing | Excluded when stale, incomplete, already included, or not approved |
| Decision | Visible facts, conflicts, unknowns, and named follow-up owner | The workbook does not choose an installer |

Buy it only when the documents exist
Built for a U.S. homeowner with two or three current written residential rooftop-solar proposals who wants to understand what each quote includes, assumes, excludes, and leaves unresolved before signing.
Do not buy it for live quote generation, installer vetting, tax determination, engineering approval, contract legal review, or customized analysis. It is not a real-time incentive database.
Release status and evidence boundary
Version 1.0.0 passed static bundle validation, native Excel formula mutation checks, and native Word export checks. No customer or installer validation has been completed. The $59 price is a controlled commercial test, not proof of demand or outcomes.
Before checkout
Will it choose the best installer?
No. It normalizes submitted facts and exposes conflicts and unknowns.
Are incentives kept current automatically?
No. You enter and date official program evidence and recheck it before acting.
Can it confirm my tax credit?
No. It records the current general federal boundary but does not determine individual eligibility.
Does it include custom review?
No. The offer is a self-service digital file package. Support covers file and reproducible formula defects.
NO SCORE. NO AUTOMATIC WINNER. NO HIDDEN ZEROES.
