1. Start here: photos
Everything is read on your device. Photos pre-fill the form below - review every amber value; nothing is auto-accepted. Blank fields stay conservative, never invented.
Paper bill, PDF screenshot, or a photo of a billing summary sheet. More bills = higher confidence.
DG set, transformer, solar inverter - reads kVA/kW ratings
2. Site & tariff (minimum)
Unique short code
Plant or customer name
Bill header / DISCOM logo
Sanctioned/contract demand on bill
Bill PF; 0.95 if unknown
How were inputs sourced
3. Energy use (minimum)
Consumption/units; average 12 months
ToD/peak units on bill; blank if unknown
Blank if unknown
Bill line when billed demand > contract demand; blank if none
Maximum/billed demand line from each monthly bill
4. Add detail: diesel generator (optional - unlocks DG displacement value)
DG nameplate
Run-hour meter / logbook
Diesel invoices / ledger
5. Add detail: solar & outages (optional - unlocks solar recovery and reliability value)
Inverter / commissioning record
Inverter portal
0 if none known - never estimated
Outage log; conservative
1.0 if unknown
Ask production head: lost margin + restart cost
Free NASA climatology - sanity check only, never a value input
Auto from NASA on check; drives degradation
6. Sizing drivers (defaults are conservative - refine when known)
Single-line diagram / critical load list
12-month demand profile; conservative
15-min meter data; 1h if unknown
Transformer spare capacity
Approved grant/tax/financing benefit only
AC-AC; 88 default. Compare PCS quotes as money
Component options (internal - PCS / cooling / chemistry vs site conditions)
Compare quotes as money; swings arbitrage margins
Drive equipment suitability flags, not model math
Chemistry: LFP is the default for C&I (thermal stability, 6,000+ cycle options). NMC only where space is the binding constraint. Cooling: liquid-cooled sealed cabinets (IP54+) for hot or dusty sites; air-cooled acceptable in mild, clean indoor rooms. Warranty cycle-life terms matter as much as the degradation %.
7. Financing (optional - EMI vs monthly value)
Leave blank to skip. Fill any one field and the rest use the defaults shown.
Default 70
