The fastest useful check: normalize the quote to solar-only $/W
A $30,000 proposal is not automatically expensive and a $20,000 proposal is not automatically cheap. System size, battery scope, roofing, electrical upgrades and financing can make total prices impossible to compare directly.
Home Solar Atlas therefore starts with the cash-equivalent project price, subtracts separately itemized battery and non-solar work, and divides the remaining solar price by DC system watts. That normalized $/W can then be compared with the current state marketplace benchmark and, when enough reviewed submissions exist, the Home Solar Atlas homeowner median.
Verify the $/W denominator before trusting the benchmark
Price per watt is only as reliable as the DC system size used in the denominator. If a proposal says 10.0 kW but its explicit module count and module wattage add up to a different nameplate, the normalized $/W comparison can move even when the dollar price is unchanged.
Check panel-count × module-wattage arithmetic first. A mismatch is a review signal rather than an automatic installer error, but it should be resolved before using the quoted kW for pricing, production-yield or DC/AC comparisons.
Upload a Solar Proposal PDF
We extract likely proposal fields from text-based PDFs, show what was detected, and let you load those values into the analyzer for manual verification.
Maximum 10 MB. Up to the first 30 pages are read. Image-only/scanned proposals currently require manual entry. Do not rely on extracted values until you compare them with the original PDF.
Quote Analyzer Readiness — incomplete
Pricing ready · Benchmark ready · Production ready · Equipment incomplete · Financing ready · Warranty review
Next action: Confirm the exact panel model. Record the exact module model rather than relying on a generic manufacturer or premium-panel description.
- Exact panel model is missing.
- Exact inverter or microinverter model is missing.
- Workmanship or installer service warranty term is still missing.
- Roof-penetration or leak warranty term is not recorded; verify whether the proposal has a separate term or exclusion.
- 1 analyzer watch flag remains for proposal review.
The solar-only cash-equivalent price is within 25% of the Texas marketplace benchmark of $2.25/W. Equipment, workmanship, roof scope and local market conditions still need comparison.
The proposal implies about 1,480 kWh/kW/year. Compare it with ZIP-specific PVWatts and the installer's roof and shade model before relying on savings projections.
A serious quote should identify the panel and inverter models, not only the manufacturer or a generic premium-equipment description.
Questions to ask the installer
- What is the cash price with no financing, and what line items are excluded?
- Does the financed number mean the financed contract price, Regulation Z Amount Financed, or the loan amount / principal?
- If this is a loan, what are the APR, Finance Charge, scheduled payment, Total of Payments and any step-up or re-amortization conditions?
- Which exact panel, inverter and battery model numbers will be installed?
- Which software and assumptions produced the annual kWh estimate?
- Which utility export rule and electricity-rate escalation are used in the savings projection?
- What are the installer workmanship, roof-penetration and service-response warranties?
Pricing benchmark: Texas average $2.25/W from EnergySage Marketplace residential solar pricing, updated September 11, 2026. Marketplace averages are useful comparison points, not appraisals. Local roof complexity, electrical work, equipment, installer scope and system size can materially change a fair quote.
This analyzer compares the numbers you entered with transparent planning benchmarks. Readiness is a data-completeness workflow aid, not an appraisal, installer rating or guarantee that a quoted price is fair for a particular roof or market.
Stress-test the battery in this quote
Choose the exact battery model and the number of full battery units written into the proposal. Home Solar Atlas will carry those equipment details into the 72-hour outage simulator. The current battery-portion price stays out of the URL and, when browser session storage is available, is carried only into the current tab for quote-based resilience economics.
Confirm a supported battery model, full-unit count and positive battery-portion price to calculate quoted package cost per usable kWh.
Quoted package $/usable kWh is a normalization metric, not a market-price benchmark or value score. Gateway/controller equipment, electrical work, labor, taxes, multi-unit discounts and bundled scope may differ between proposals. The total quoted package price is never used to invent first-unit or incremental-unit pricing.
Have more than one installer proposal?
Do not compare PDFs by headline total or monthly payment alone. Quote Compare runs two or three proposals through the same extraction logic, adds live Proposal Readiness and places normalized $/W, production, financing, equipment and review flags in one side-by-side flow.
What can make a higher-priced quote reasonable?
- Complex roof geometry, steep pitch, multiple roof planes or difficult access.
- Premium modules, microinverters, batteries or longer equipment warranties.
- Main-panel upgrades, trenching, structural work or other electrical scope.
- Local permitting, interconnection and labor conditions.
- Stronger workmanship warranty or service capability.
A benchmark is a comparison point, not a verdict. A proposal far above the local range deserves an explanation; a proposal far below it deserves verification that scope and equipment are truly comparable.
Use two independent comparison layers
The analyzer compares your quote with the current external marketplace benchmark from EnergySage Marketplace residential solar pricing. It also checks the moderated Home Solar Atlas homeowner dataset when enough approved quotes exist in the selected state.
Frequently asked questions
How do I know if my solar quote is too expensive?
Review the proposal scope first, then start with the solar-only cash-equivalent project price, remove separately itemized battery and non-solar work, divide by verified DC system watts, and compare the resulting dollars per watt with current state and homeowner quote benchmarks. Equipment, roof complexity and local scope can still justify differences.
Why should I verify the DC system size before comparing solar price per watt?
DC system watts are the denominator in a dollars-per-watt calculation. If the quoted system size does not reconcile with panel count and module wattage, the resulting price per watt can be misleading even when the project price itself is correct. Verify the nameplate arithmetic before relying on the normalized comparison.
What should I verify before trusting a solar price-per-watt comparison?
Confirm system size, exact panel and inverter models, annual production assumptions, cash price, non-solar add-ons, financing and dealer-fee treatment, incentive assumptions, electrical work, permits and interconnection, monitoring and warranty responsibilities. A lower price per watt is not meaningful if the proposal scope is materially different.
Can I upload my solar quote PDF for analysis?
Yes. Home Solar Atlas can extract likely fields from text-based proposal PDFs, show the detected values for review, and load them into the quote analyzer. Scanned or image-only PDFs currently require manual entry. Extracted module-group arithmetic and other diagnostics should still be confirmed against the original proposal.
Should I compare solar quotes by total price or price per watt?
Price per watt is usually more useful for comparing systems of different sizes, provided the price is normalized to solar-only cash-equivalent cost and the DC system size is correct. Total price still matters for budget and financing decisions.
Do solar loans make a quote look more expensive?
They can. Financed contract prices may include dealer fees or other financing costs, so compare the cash-equivalent project price, the meaning of each financed amount, APR and total payments instead of relying only on the monthly payment.
Is the cheapest solar quote always the best quote?
No. A very low quote should still be checked for equipment model, permitting, interconnection, electrical scope, workmanship warranty, service support and realistic production assumptions.
