Getting an Independent Review of a Commercial Solar Proposal in NC and VA

A commercial solar proposal from an installer is a sales document. That is not a criticism — it is simply what it is. The production estimates, financial projections, and contract terms in a proposal are prepared by a party with a financial interest in the project moving forward. Before a North Carolina or Virginia commercial property owner signs a contract, an independent review of that proposal can identify where the analysis is incomplete, where assumptions are optimistic, and where contract terms create risk.

What a Proposal Review Examines

An independent proposal review for a commercial solar project in North Carolina or Virginia typically covers several areas:

• Production modeling: Is the estimated annual output based on actual interval data from your utility bills, or on a rule-of-thumb estimate? Does the model account for shading, roof orientation, and system degradation over time?
• Demand charge claims: If the proposal claims the system will reduce demand charges, is that claim supported by analysis of your actual load profile and the utility rate schedule? Duke Energy and Dominion Energy demand charge structures vary by rate class, and a generic claim is not the same as a verified reduction.
• Incentive assumptions: Are the federal tax incentives in the financial model applicable to your tax situation? Are any state or utility incentives included based on current program availability?
• Financing terms: If the proposal includes a PPA, lease, or C-PACE structure, what are the escalator provisions, assignment terms on property sale, and end-of-term options?
• Contract terms: What are the performance guarantees, warranty provisions, and remedies if the system underperforms?

Common Issues Found in NC and VA Commercial Proposals

Commercial solar proposals in North Carolina and Virginia share some common patterns that an independent review can identify. Production models are sometimes based on idealized conditions rather than actual site data. Demand charge reduction claims are sometimes included without supporting load profile analysis. Financial models sometimes assume the full value of federal tax incentives without accounting for the owner's actual tax position. Financing terms — particularly in PPA and lease structures — sometimes include escalators and assignment provisions that are not prominently disclosed.

None of these issues necessarily make a project a bad decision. But they affect the accuracy of the financial case, and a property owner who understands them is in a better position to negotiate terms and set realistic expectations.

How the Review Process Works

Solar Power San Diego reviews commercial solar proposals for property owners in North Carolina and Virginia as an independent advisor — with no installer commissions and no financial interest in which project moves forward. The process starts with a review of the proposal documents and, where available, utility bills with interval data. We provide written findings that identify where the analysis is solid and where it has gaps, and we give property owners a clear picture of what the project actually involves before they sign.
