The $100k mistake in C&I solar modeling? Ignoring the "Wet-Stacking" threshold.
Most feasibility reports treat solar+BESS+Diesel as a simple math problem: [Demand - Solar - BESS = Diesel].
That’s how you design an asset that kills the engine.
If your simulation doesn't respect the 30% minimum load floor (ISO 8528-1:2005), you aren't optimizing for savings. You’re optimizing for engine failure.
When you force a diesel genset to run at 5% or 10% load to "maximize" solar, you cause wet-stacking—unburned fuel accumulating in the exhaust system. This leads to carbon buildup, increased maintenance, and premature engine retirement.
An institutional lender doesn't see "savings." They see a project with a high probability of mechanical default.
The only way to build a bankable hybrid system is through a deterministic Merit-Order Dispatch loop that treats the engine as a protected asset. (See the telemetry loop below).
If your modeling software can’t simulate the dispatch hierarchy to protect the engine floor, it’s not a feasibility tool. It’s a calculator that’s ignoring the physics of your infrastructure.
