Solar & EV installer CFO services: the gap between cost and funding

Costs arrive early; funding arrives at commissioning

Panels and inverters are often paid for, or drawn against a pallet already sitting in inventory, at the point an install is scheduled. The crew is paid on the usual payroll cycle whether or not the job has closed. The cash that pays for all of it — the customer's final payment, or a financing partner's funded amount — does not move until commissioning, once the inspection and the utility approval are both done, which can run weeks behind the physical install. A company scaling from one crew to three, or expanding from solar into EV chargers, magnifies that lag rather than shrinking it, because more jobs are open at once. How to build a 13-week cash flow forecast describes the general method; for an installer, the rows are open jobs and the columns are the deposit, mounting, and commissioning dates on each one.

The financing partner you choose is a margin decision

Offering a financing partner at the point of sale converts a price objection into a sale, and it comes at a cost: a dealer fee, deducted from the amount the financing company funds you, priced to the promotional term the customer is offered. A longer no-interest period generally carries a higher fee than a shorter one, which means the financing option that closes the most deals is not automatically the one that protects margin best. We model the blended cost of the financing mix a sales team is actually offering, not just the headline rate on the brochure, and compare it against cash and rebate-assisted deals that carry no dealer fee at all. Whether to lease or buy equipment covers the same lens applied to your own trucks and tools.

Buying ahead of a tariff is a cash decision dressed as a purchasing one

When a tariff or duty change on imported panels, inverters or racking is announced ahead of its effective date, the tempting move is to buy a season's worth of inventory before the new rate applies. That protects the landed cost, and it also ties up cash in a warehouse and exposes you to a technology or pricing shift before the inventory is installed. We model the carrying cost of the purchase against the tariff exposure it avoids, using the same cost-per-watt figure the sales team already prices jobs from, so the decision is made with a number rather than a hunch about where policy is headed next.

Fund the warranty reserve, or buy the insurance for it

A workmanship warranty that runs years past the sale is a real obligation, and there are two honest ways to carry it: hold cash in a dedicated reserve sized to your callback history, or pay a third party for an insurance-backed warranty product so the promise survives even if the company someday does not. Neither is free, and the right answer usually shifts as volume grows — self-funding is cheaper at small scale and an insured product becomes more attractive once the tail of open warranties gets long enough that a bad season could otherwise strain the reserve. We size both paths against your actual install volume rather than treat the choice as one-size-fits-all.

Growth decisions in this business tend to be about mix as much as volume: how much crew capacity goes to higher-margin EV charger work with a shorter, more predictable install cycle versus rooftop solar with its longer commissioning tail and seasonal swing. The monthly engagement is a closed set of books, an updated cash forecast, and a quarterly conversation about financing terms and inventory timing, at a fixed fee set after a discovery call. Equipment sourced from outside Canada adds tariff exposure covered in our cross-border guide for solar and EV installers; the general engagement is described on our advisory and CFO services page.
