From proposal to plain-language review.

Bring the offer you have. We’ll help you understand the numbers, the terms, and the questions worth asking.

  1. Documents being gathered for a solar proposal review.

    Step 1Your documents

    Share what you’ve been offered.

    Upload your solar proposal as a PDF, photos, or screenshots. Have a contract? Include the version you would sign so we can compare it with the proposal.

    • A recent utility bill is optional. It helps us check the proposal against your electricity use.
    • Confirm the important details we read from your documents before the review runs.

    Both review options are free for a limited time. No card or emailed code is required.

  2. Review topics connected to independent references and the limits of available information.

    Step 2Our independent checks

    We look beyond the sales pitch.

    We compare the proposal with independent solar models, equipment references, pricing research, and the utility information available for your home.

    • Price, financing, and savings: the costs and assumptions behind the offer.
    • Production, equipment, and storage: the claims about what the system can do.
    • With contract review: the terms you would sign and how they match the proposal.

    If a check can’t run, we explain what’s missing. We don’t fill gaps with guesses.

  3. A plain-language report with findings and questions to discuss with the seller.

    Step 3Your next conversation

    Know what to ask before you sign.

    • See what we verified, what needs another look, and what we couldn’t check.

    • Use the questions to ask for clarification or a revised proposal.

See the data behind your review.

We compare the details in your proposal with public models, equipment catalogs, utility data and published research. Here are the references behind those checks.

The parts of a solar proposal that deserve a closer look.

See every check
Starts with you

Fit to your goals

If you know what you want, we use it. If you are still figuring that out, we still read the proposal and flag extras you may not need.

Energy estimate

Is the yearly production realistic for this roof, with honest shading? We model it independently.

Price and savings

Project price, cash versus financed cost, incentives, utility-rate assumptions, and the math behind the savings story.

Equipment and battery

Named models, stated specs, storage sizing, and backup claims checked against independent equipment data.

Payment and financing

Interest rate, fees, payment changes, total cost, and end-of-term terms where they appear.

Installer and warranties

Contractor information in the documents, workmanship terms, and equipment warranties.

Contract and fine print

With Bid + Contract Review: whether the contract matches the proposal, and what the document actually says about cancellation, payments, and equipment swaps.

Storage

Can the solar system recharge the battery, and how long could it power the appliances you need during an outage?

Contractor licensing

Does the proposal identify the company responsible for installation and include a license number?

What is missing

If the documents do not contain enough information for a check, the report says so and explains the gap.

Examples of questions worth asking.

Illustrative patterns we check for. Every bid is different. These are composites, not a customer testimonial.

Illustrative solar proposal with its assumed yearly electricity-price increase circled
Illustrative proposal · assumed electricity-price increases affect projected savings
Savings+$11,500 overstated

An incentive the purchase does not qualify for

Bid saidNet price includes an incentive.
We foundIn this illustrative example, the incentive’s eligibility requirements were not met. Removing it raises the homeowner’s expected cost by $11,500.
Finance~$7,800 hidden

Cash and financed prices, identical

Bid said“Same great price whether you pay cash or finance.”
We foundMatching prices deserve a question about financing fees. In this illustrative example, the financed amount includes a fee that increases the homeowner’s cost.
Production14% too high

A roof with “0% shading”

Bid said12,180 kilowatt-hours of energy per year, with no allowance for shade.
We foundIn this illustrative example, accounting for shade produced an energy estimate 14% lower — reducing savings and lengthening the time to recover the purchase cost.
SavingsYears added to payback

Electricity prices assumed to rise 5.9% a year

Bid saidBills rise 5.9% every year for 25 years.
We foundThat single assumption inflates lifetime savings dramatically. Compare the assumed increase with the utility’s history. A lower increase would mean lower projected savings.
EquipmentWarranty mismatch

A panel that was quietly discontinued

Bid saidPremium modules, 25-year warranty.
We foundThe listed model was off the current approved-equipment data — and the warranty didn't match the hardware.
StorageBackup claim overstated

A battery that couldn't refill

Bid said“Whole-home backup, day after day.”
We foundDaily solar fell short of the battery's usable capacity — it would not fully recharge on an average day, leaving less energy available for the next outage.

The homeowner is the customer we serve.

What we are
An independent, third-party read on a residential solar bid.
A report you can keep, share, and take back to the seller.
A consumer-side check before you commit, not a path into a sales funnel.
Like a home inspection — a read you use once, before you sign.
What we are not
A place that sends your name to installers.
A marketplace, auction, or ranking of companies.
A company that sells your documents or contact details.
Legal, tax, financial, or engineering advice.

Built for homeowners across the United States, with honest limits.

We review residential solar proposals nationwide. Some checks depend on local utility data, licensing records, and equipment lists. When a check cannot run, the report says “not checked” and explains why.

A neighborhood of homes with rooftop solar

Questions homeowners ask.

Are solar quote and contract reviews really free?
Yes. Both Bid Review and Bid + Contract Review are free while this offer is active. Start a review, upload your documents, choose the review you need, and accept the review-scope disclosure. The offer applies automatically at checkout: your total is $0, with no card or code to enter. Requesting an emailed code and agreeing to a feedback email are optional.
Can’t I just ask AI to review my solar proposal?
AI can help explain a proposal, but a useful review depends on knowing which questions to ask and checking details against relevant solar and local information. BidProof uses a consistent solar-specific framework to create a plain-language report with findings and questions to take back to your installer. If a closer look is needed, a human reviewer can step in.
What documents do I need?
Send your solar proposal for Bid Review. For Bid + Contract Review, include the contract you would sign and the proposal so we can compare them. If you only have the contract, we explain what we could not compare without the proposal. PDFs, photos, and screenshots are fine. An electricity bill is optional but recommended. Upload one recent bill, including its 12-month usage history if shown, to help us check the proposal against your electricity use.
Can I add my contract later?
Yes. You can start with your quote now. While this offer is active, Bid + Contract Review is also free. When your contract is ready, start that review with both documents so we can compare them, or contact support@bidproof.com with your original report link for help. Send the contract before you sign.
What does BidProof check?
We review the proposal’s price, estimated production, savings assumptions, equipment, incentives, financing, warranties, and other details the documents support. Bid + Contract Review also checks the contract against the proposal and explains terms that may deserve a closer look.
How long does a review take?
Automated reviews are completed instantly. If your bid needs a human review, expect your report within 2 business days, usually sooner.
What if my documents don’t include enough information?
The report marks a check “not checked” when the documents or available data don’t support a conclusion, and explains what is missing. It won’t guess; you’ll see questions you can take back to your installer.
Is BidProof’s contract review legal advice?
No. We explain what the contract says and flag terms or gaps to understand. BidProof does not provide legal, tax, financial, or engineering advice.
