Tool 02 — All-in-One Platform
DEO Solar OPTRTA
The only solar platform that takes you from load profile to signed-off client quote without leaving a single tool. Load analysis, roof layout, yield simulation, financial modelling, and custom quoting — all in one place.
Platform Features
Everything in one workflow
No switching between tools, no rekeying data. OPTRTA links every stage — from the client's meter to their signature on the quote.
Load Profile Analysis
Analyse historical consumption data — hourly, daily, and monthly — to right-size the system for actual demand patterns rather than assumptions.
Roof Layout & Stringing
Plan panel placement on your roof model, define string configurations visually, and export the layout directly to the design report.
Yield Simulation
Model annual energy output based on local solar irradiance, installed kWp, and battery storage capacity. See monthly and daily yield projections.
Financial Modelling
Pre-populated PPA, lease, and cash purchase models with sensitivity analysis, NPV, IRR, and payback period — all driven by the simulation output.
Custom Quote Builder
Build a branded, client-ready proposal directly from the system design output. Line items, finance options, and savings projections — no copy-paste.
Design Verification
Built-in compliance checks verify every design against engineering standards and SANS requirements before the proposal leaves the platform.
