A Qualification Worksheet for Commercial Solar and EPC Sales

The most important qualifying question in a commercial solar or energy EPC sale is whether the facility owner has, or can get, financing that makes the payback math work for their finance committee. Build a worksheet around that question instead of a generic discovery call, so deals that will never close stop consuming months of engineering and design time.

Worksheet Section One: Metrics the Finance Committee Actually Uses

Write down the specific financial metric the facility owner's finance committee evaluates a capital project against, payback period, internal rate of return, or a simple cash-versus-lease comparison against a power purchase agreement. Many solar and EPC sales conversations stay at the level of 'this will reduce your energy costs' without ever confirming which number the actual approver is looking at, which produces a proposal that answers the wrong question.

If your contact cannot answer this, that is itself useful information: it usually means you are talking to someone below the level where the real financial evaluation happens.

Who Is the Economic Buyer and Who Controls Financing?

Name the Economic Buyer explicitly, and separately, name who controls the financing decision, because for many commercial solar projects these are not the same conversation. A CFO might approve the project's business case while a completely separate financing decision (cash purchase, a PPA structure, or a third-party lease) is negotiated with different terms and different approvers. A facility owner who is enthusiastic about the environmental and cost case can still stall for months if the financing path was never mapped.

Ask directly, early: is this project more likely to be financed with cash, a loan, or a PPA, and who owns that decision. The answer changes your entire proposal structure, not just your pricing.

Worksheet Section Three: Interconnection and Site Realities as Decision Criteria

Utility interconnection timelines and site-specific factors (roof condition, available land, existing electrical infrastructure) function as real Decision Criteria even when the facility owner does not initially think of them that way. A project that looks financially attractive can stall for a year on an interconnection queue the owner did not know existed. Surface this early with a site assessment, and use it as a legitimate reason to accelerate a decision: financing terms and interconnection queue positions both tend to move against the buyer the longer a decision drags.

How Do You Open With a Skeptical Finance Committee?

Facility owners who have shopped several EPC contractors have usually heard the same environmental and cost-savings pitch repeatedly. A Challenger-style conversation instead brings something the finance committee has not modeled themselves, a specific comparison of how utility rate exposure compounds over a project's life against the fixed cost of a system, tailored to their actual usage pattern rather than a generic estimate.

This reframes the finance committee's evaluation from 'is solar worth it in general' to 'what does staying on the current utility rate structure actually cost us over the next decade,' which is a harder question for a competitor's generic proposal to answer as specifically.

Worksheet Section Five: The Champion Who Survives a Long Sales Cycle

Commercial solar and EPC deals run long by nature, and the facility manager or sustainability lead who championed the project early can lose momentum, change roles, or get deprioritized before the finance committee ever votes. Check in with your champion regularly enough to know if their internal position has shifted, and make sure at least one other stakeholder, ideally someone closer to the finance committee itself, understands the project well enough to keep it alive if your original champion moves on.

A single point of internal advocacy is the most common reason a well-qualified solar deal quietly dies midway through what is already one of the longer sales cycles in B2B selling1.

Worksheet Section Six: Incentives and Tax Credit Timing as a Forcing Function

Tax credit structures and utility rebate programs change on timelines the facility owner does not control and often does not track closely. Where a genuine, verifiable deadline exists, an incentive program's application window closing, a rebate budget running low, use it as a legitimate forcing function in the sales conversation rather than an artificial urgency tactic. Confirm the actual deadline directly with the program administrator rather than repeating a vague claim about incentives running out, since a false urgency claim that does not hold up damages trust with a finance committee that will remember it at the next vendor conversation.

When a real deadline exists, tie it explicitly back to the financial metric from worksheet section one: showing the finance committee exactly how much the payback period worsens if the decision slips past the deadline is a far stronger argument than simply saying the incentive is expiring soon.

Before you advance a solar or EPC deal, confirm each of these on the worksheet:

  • Which financial metric the finance committee uses to judge the project: payback period, internal rate of return, or a cash-versus-lease comparison against a power purchase agreement.
  • Who the Economic Buyer is, and separately who controls the financing decision, whether a cash purchase, a PPA structure, or a third-party lease.
  • Whether utility interconnection timing or site conditions such as roof condition, available land, or existing electrical infrastructure could stall the project.
  • Whether a second stakeholder close to the finance committee supports the project alongside your original champion.
  • Whether any incentive or rebate deadline is genuine and verifiable before you use it as a forcing function.
Executive Capability Standard

What Good Looks Like

A mature commercial solar and EPC sales process confirms the finance committee's actual evaluation metric and financing path before building a full proposal, and maintains more than one internal champion through a long decision cycle.

Building The Capability (5-Stage Skill Ladder)

1. Learn:Review your last several qualified-but-stalled solar deals and note whether the financing path was ever confirmed early in the process.
2. Do Manually:Build a short qualification worksheet covering finance committee metric, economic buyer, and financing path for every new opportunity.
3. Delegate:Assign a dedicated project development lead to track interconnection status and financing path separately from the sales conversation.
4. Automate:Use Salesloft to maintain a structured check-in cadence with champions through a long, multi-month decision process.
5. Buy:Track deals in Salesforce with required fields for financing path and finance committee metric before a full proposal is built.

Frequently Asked Questions

What's the single most important qualifying question for a commercial solar deal?

Whether the facility owner has a clear financing path, cash, loan, or a power purchase agreement, and who controls that decision. A financially attractive project can stall indefinitely if the financing structure was never confirmed alongside the business case itself.

Why does interconnection timing matter for sales qualification, not just engineering?

Because a project that looks financially sound can stall for a year on a utility interconnection queue the owner did not anticipate. Surfacing this early, through a site assessment, gives you a legitimate reason to help the buyer move faster, since both financing terms and queue position tend to worsen the longer a decision drags.

How do we prevent a long sales cycle from losing momentum internally?

Check in with your champion regularly enough to notice if their position or priorities have shifted, and cultivate a second internal advocate closer to the finance committee. A single point of internal support is the most common reason a well-qualified solar or EPC deal quietly stalls partway through a long decision process.
