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.
