From proposal to question

What can a solar bid check reveal?

A price or savings claim needs context. These examples show the questions a review can raise. They are illustrations, not findings from a customer’s proposal.

A cash price and a larger loan

A proposal lists the same installation at $24,000 cash and $30,000 financed. The $6,000 difference needs an explanation. It is not proof that the entire difference is a dealer fee.

Ask: Can you reconcile the two prices for exactly the same work and show the loan disclosures?

Understand solar dealer fees

An energy estimate without roof assumptions

A yearly kilowatt-hour total does not explain how the seller modeled your roof. System size, orientation, shade and losses help determine whether an estimate can be checked.

Ask: What roof planes and shading assumptions support the annual production figure?

Read a solar production estimate

A long warranty with unclear repair costs

A headline warranty term may cover a replacement part while leaving labor, shipping or other service costs unresolved. The exact model and written terms matter.

Ask: Who handles the claim and pays for removal and reinstallation?

The method behind the review

A consistent check of the offer in front of you.

BidProof combines a solar-specific review framework with reference data and AI-assisted document analysis. Relevant checks may use production models, utility information and equipment catalogs. Availability depends on your documents, location and the source.

Our team’s experience in solar engineering, pricing, operations and software informs that framework. A team biography does not mean that person personally reviewed your bid.

Know what the review can establish.

Each report separates findings from missing or unsupported information. A model estimate is not a performance guarantee. A document review does not replace a site inspection or legal, tax or engineering advice.

Read the sources and methodology and coverage and limits. Contract checks are included with Bid + Contract Review.

Prefer to make a first pass yourself? Start with how to review a solar quote and the price-per-watt guide.

Clarity you can take back to your seller.

A digital report with findings, explanations, and practical questions. Download it, print it, or share it as you weigh your next step.

Every result reflects the checks we could complete. A review does not guarantee savings or performance.

What is a solar proposal review or solar bid check?
A solar proposal review checks the offer you already have before you sign. BidProof reads your bid or quote, checks supported details against independent reference data, and explains findings, missing information and questions for your seller. Each review covers one proposal; contract terms require Bid + Contract Review.
Which documents should I send?
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.
Will you recommend an installer?
No. We review the documents you bring. We do not rank or refer installers, receive installer referral fees, or sell your information to installers.
Can I send the contract later?
Start with the proposal you have. If the contract comes later, contact support with your original review details so we can arrange the next step. Both review scopes are free while the free offer is active.
Do I need to sign up to receive the offer by email?
No. Receiving the offer by email is optional. The free offer applies automatically at checkout, and no card or emailed code is required.
Have the contract, too?

Review the promise and the paperwork.

Bid + Contract Review includes the proposal checks and a review of the contract you would sign.
