Review the preliminary layout with a commercial solar specialist. We’ll confirm roof condition, structural requirements, utility service, and the next feasibility steps.
Analyze a commercial roof
Commercial decision tool
Upload a proposal to organize its technical, production, price, financing, ownership, O&M, warranty, tax-assumption, and exclusion terms before your team relies on the economics.
The short answer
A useful commercial proposal check does not start by calling the price high or low. It first confirms that system size, production, scope, payment structure, ownership, O&M, warranties, tax assumptions, utility/roof exclusions, and exit terms are stated clearly—and that the proposal's own numbers agree with one another.
Anonymous first pass
The checker returns the extracted terms and follow-up questions immediately. A human review is optional and appears only after the result.
Why the structure matters
A cash EPC proposal, financed ownership, C-PACE assessment, PPA, and lease are not five labels for the same transaction. They can change who owns the system, who pays for maintenance, who receives tax benefits, how the price changes, what happens when the property is sold, and who carries removal or restoration duties.
Model the extracted financing termsDC/AC size, equipment schedule, first-year production, losses, degradation, installed cost, and the definition used for price per watt.
Deposits and milestones, financed principal, rate and term, PPA price and escalator, ownership, transfer, default, and end-of-term options.
Monitoring, preventive and corrective maintenance, response times, equipment replacement, roof access, removal/reinstallation, insurance, and restoration.
Who is modeled to receive credits and depreciation, what eligibility assumptions are used, explicit exclusions, change-order rules, and adviser-review conditions.
Commercial scope can change materially with structure, roof condition, switchgear, transformers, utility upgrades, site access, labor requirements, storage, and financing. The tool checks internal math rather than applying one national $/W benchmark.
The checker reports what the proposal assumes and who it says receives the benefit. It does not decide tax eligibility, credit rate, basis, adders, transferability, elective pay, depreciation treatment, timing, or recapture.
A proposal does not prove roof capacity, electrical capacity, utility hosting capacity, permit acceptance, constructability, or final production. Those require the applicable professional and utility processes.
Missing-term and inconsistency findings are questions for diligence. They are not a legal conclusion that a contract is enforceable, unenforceable, complete, incomplete, safe, or unsafe.
For current tax forms and eligibility instructions, use the IRS Form 3468 instructions. For an example of how ownership, operations, maintenance, and eventual removal can be allocated in an on-site electricity contract, review the Department of Energy's sample PPA documents. Those sources are references, not a substitute for project-specific professional advice.
No. The proposal checker reads the file in request memory and does not write the uploaded document to NuWatt's database or file storage. The file is sent to NuWatt's AI model provider for the real-time analysis. If you request a human review, NuWatt saves the extracted summary and issue list with the lead, not the uploaded document.
No. It extracts proposal terms, recalculates internal arithmetic, and identifies terms that appear absent or inconsistent. It is not legal, tax, engineering, accounting, financing, or investment advice. Contract acceptance should be reviewed by the appropriate qualified advisers.
It looks for system size, equipment, production, installed cost, price per watt, payment milestones, loan or C-PACE terms, PPA or lease pricing and escalation, ownership, tax-benefit assumptions, O&M, monitoring, roof-work duties, warranties, transfer language, end-of-term options, assumptions, and exclusions.
No. Commercial pricing changes with roof condition, structure, electrical scope, switchgear, utility upgrades, labor rules, site access, storage, and financing. The checker only recomputes the proposal's own arithmetic. A specialist can build a project-specific comparison after reviewing the property and scope.
Yes. The checklist changes with the detected payment structure. Ownership proposals are checked for installed cost and payment milestones; financing is checked for rate and term; PPAs and leases are checked for starting price or payment, escalation, contract term, ownership, O&M, transfer, and end-of-term language.
