In-House vs Outsourced Solar Operations

Six functions, and organisations usually underestimate the count because several of them are invisible until they fail. Site survey to a written standard. Design and engineering, producing a plan set a jurisdiction will approve. Permitting, meaning submission, correction cycles and revisions with the authority having jurisdiction. Interconnection, which is a separate approval track with the utility on its own timeline. Funding operations, meaning milestone packet assembly, portal submission and stipulation clearing. And project management holding the sequence together from signed contract through to permission to operate. Materials procurement and logistics sit alongside them. Building in-house means staffing all of these, not the one or two that are most visible.

There is no single threshold, and any specific number quoted without reference to your mix is guesswork. The honest framing is that the cost of running these functions in-house is largely fixed and steps up in discrete jumps as you hire, while outsourced cost is largely variable per project. So the question is not what your current volume is but how stable it is, how many jurisdictions and utilities you work across, and whether you can keep a specialist busy. An organisation doing predictable volume in a small number of jurisdictions reaches the crossover far earlier than one doing the same volume spread across many.

Coverage rather than headcount. A single permitting coordinator is not a permitting function, because that person takes holidays, gets sick and eventually leaves, and while they are away the correction cycles do not pause. The same applies to design and to funding operations. The genuine cost of an in-house function is the smallest number of people that can cover it without a single point of failure, which is usually more than the first hire an organisation budgets for. The second hidden cost is jurisdictional learning: every new authority having jurisdiction is a fresh set of requirements someone has to acquire, and that acquisition happens at the expense of live projects.

Losing the thread on accountability. Outsourcing to several specialised vendors, one for design, another for permitting, another for installation, recreates the coordination problem you were trying to remove and adds contract boundaries to it. When a project stalls, each vendor is individually correct that the delay is somewhere else. The mitigation is to check where responsibility actually sits, particularly who is the licensed contractor of record on the permit, because that is the party a jurisdiction and a homeowner hold responsible regardless of how the work was divided.

Yes, and the control comes from the reporting rather than from doing the work. What determines whether a homeowner feels well handled is whether someone can answer where the project is and what happens next. That is a milestone visibility question. An organisation that outsources delivery but receives milestone status it can act on retains the customer relationship; one that outsources delivery and receives silence has given away more than the work. Treat status visibility as a requirement of the arrangement rather than a nice-to-have.

Frequently it is the right answer, and it is the most common arrangement in practice. The useful rule is to keep in-house what is genuinely differentiating or genuinely local, and outsource what is specialised, jurisdictionally variable and expensive to staff for coverage. Sales, customer communication and local relationships tend to belong in-house. Design, engineering, permitting and funding operations are the ones where a small organisation is paying full fixed cost for partial utilisation. The failure mode to avoid is splitting a single sequence across the boundary so that no one party can see it end to end.

Compare fully loaded fixed cost against per-project variable cost, over a volume range rather than at one point. On the in-house side that means salaries plus employment costs, software and design tooling, training, management time and the cost of coverage during absence, not just base pay. On the outsourced side it means the per-project fee plus whatever internal coordination time remains, because it is rarely zero. Then look at what happens to each line if volume halves, because that asymmetry, fixed cost that does not fall against variable cost that does, is usually the deciding factor rather than the cost at plan.
