☀

Yield Engine

Single/two-diode module modeling, run as a full 8,760-step hourly (or 15-min sub-hourly) simulation, calculating the exact amount of electricity a solar power plant will produce over its lifetime, not a monthly approximation.

◐

Bifacial & Shading

For bifacial solar tracking, view-factor bifacial, 3D near-shading, horizon and SAT backtracking algorithms prevent row shading and self-shading and optimize tilt to maximize total energy.

📉

IEC Loss Accounting

Thermal, IAM, spectral, soiling, LID, mismatch and aging — every loss modeled with an accounting method that forces lenders to estimate and set money aside for loan defaults before they actually happen.

🔌

Electrical & Protection Design

String sizing, cable schedules and protection ratings to IEC 60364-7-712, IEC 60269-6 and CEA 2010 — plus India's IS 16169.

🏦

Bankability & Risk

P50/P75/P90/P95 exceedance, 5,000-trial financial risk analysis, Equity IRR/DSCR tornado, and a full lender due-diligence checklist.

🔋

Battery & Self-Consumption

Hourly AC-coupled battery dispatch — self-consumption, peak shaving, and weak-grid/islanding — against an imported or estimated load profile.

📋

EPC Proposals & Reports

Auto-generated single-line diagrams, BOQ, and investor-ready PDF reports, complete with CAPEX/OPEX, cover letter and terms.

🇮🇳

Built for India

CEA / IS 16169 compliance, MNRE CO₂ factors, ALMM-ready module data, and PM Surya Ghar / DPR-style report layouts out of the box.

🔬

Research & AI Diagnostics

Sensitivity analysis charts, in-depth uncertainty analysis, and transparent in-browser AI/ML models trained on your own simulation data.

Advantages

Built for real-world, multi-market deployment.

Nine capabilities that turn a simulation tool into a bankable, EPC-ready platform.

💱

Multi-Currency & Country Tax Framework

Every CAPEX, OPEX, tariff, revenue and NPV figure runs in the project's own currency (₹, $, €, £ and more), with country-specific tax rates, depreciation schedules, CO₂ grid factors and CAPEX/Wp bankability bands — one model, re-costed for any jurisdiction without a rebuild.

🗂

Flexible Component Database

Add PV modules and inverters via manufacturer .PAN/.OND import, automatic PDF datasheet extraction, or manual entry — including hybrid-inverter battery parameters — so the workflow never blocks on missing files.

🌤

Solar Resource & Uncertainty

Source irradiance from PVGIS, NASA Hourly TMY, or imported Meteonorm/SolarGIS/SolarAnywhere data, with year-on-year variability feeding a transparent P50–P95 Monte-Carlo uncertainty budget for realistic debt-sizing.

🧭

Orientation & Irradiance Optimization

One-click tilt/azimuth optimization, orientation-loss-vs-optimum reporting, an explicit yearly transposition factor, and monthly (not just annual) POA irradiance to capture seasonal and monsoon dips.

🏗

Flexible System Design

Model hourly self-consumption/BESS dispatch with battery sizing and backup-autonomy tools, and scale from a single string to multiple independently-configured sub-arrays within one project.

🧮

Transparent Simulation Engine

Every loss and gain across GlobHor → GlobInc → GlobEff → E_Array → E_Grid — shading, IAM, soiling, bifacial gain, mismatch, wiring, clipping, grid-delivery losses — is individually editable, not buried in one black-box number.

📊

Financial & Bankability Analysis

LCOE, NPV, IRR, ROI, Project/Equity IRR, DSCR, three payback lenses, and a full Financial Due Diligence report combining hourly Perez-engine yield with Monte-Carlo risk — ready for a lender's independent engineer.

🧪

Advanced Analysis Tools

Queue batch/parametric simulations across tilt, module, inverter and ILR variants, then let an AI-assisted step recommend the best-performing configuration across yield, financial and bankability outcomes together.

📑

Professional Reporting & EPC Deliverables

Generate SLDs, array tables, protection & cable schedules, AI/ML performance-improvement recommendations, and client-facing EPC proposals with BOQ — all from the same design, so drawings never drift from simulation.
