The product
MijAi, BESS + Solar Investment Simulator built for energy developers
The challenge

Renewable-energy deals were modeled in weeks, and trusted on faith.

Sponsors, developers and bankers structured PV + battery projects in sprawling Excel files: slow to build, easy to break, and impossible to audit line by line. A single wrong assumption could sink an IRR, a DSCR covenant or a whole financing round, and nobody could re-run a scenario without rebuilding the sheet by hand. MijAi needed to make project finance fast, reproducible and bankable.

What we built

A modeling engine with a dashboard investors actually trust.

PV + BESS simulation

Hour-by-hour dispatch for solar and battery storage, with round-trip efficiency, degradation and grid limits modeled explicitly.

25-year cash waterfall

Full project cash flows, debt sculpting and covenant analysis feeding IRR, NPV and DSCR, no manual rebuilds.

800-hour LV compliance

Israel's 800-Hour LV regulation and the peak-window bonus are built into the engine, not bolted on afterwards.

Instant scenario switching

Live KPIs recompute the moment an input changes, compare sizings and strategies side by side in real time.

Auto-optimizer

A 4-phase derivative-free search finds Max Footprint, Max Equity IRR and Max NPV configurations automatically.

IC-ready deliverables

Eight-sheet investment-committee Excel exports plus shareable, audit-logged read-only links with revocation.

The results

Validated against Excel, and faster by five orders of magnitude.

IRR validated on the Climetix case

Benchmarked on a real deal, 763 kWp PV, 2,610 kWh storage, MijAi reproduced the audited 21.03% IRR within ±0.6% of the reference Excel, while turning a multi-week modeling exercise into a sub-second recompute.
