IST PVSolar Simulator
Specifications
The IST PVSolar Simulator V9.0.0 is found to be one of a small number of platforms that natively combines all three report in a single tool — hourly/sub-hourly Simulation Report, a Protection & Cable Schedule with a generated single-line diagram and cable sizing, and Bankability report. India-context PV Solar Software (BIS IS 16169, CEA Regulations 2010, MNRE references throughout) — one of the few simulators built around Indian standards.
Most PV design tools stop at "how much energy will this plant make." IST PVSolar Simulator's separate Research workbench goes further, into the kind of diagnostic work an R&D or asset-performance team does after a plant is already operating.
Diagnostics & sensitivity
- Parametric sensitivity / tornado charts on yield and IRR
- SCADA-vs-simulated benchmarking for operating plants
- Degradation and repowering scenario studies
Characterisation studies
- Thermal behaviour (NOCT/NMOT sensitivity)
- Spectral response (First Solar / Lee-Panchula correction)
- Bifacial gain isolation (view-factor vs. albedo vs. row pitch)
Forward-looking risk
- IPCC AR6 climate-shift stress testing on long-term yield
- Agrivoltaics land-equivalent-ratio (LER) analysis
- Monte-Carlo (5,000-trial) P50–P95 uncertainty stacks
1. Irradiance & Physics Engine
The resource and yield calculation core: how sunlight on a horizontal plane becomes AC energy at the meter, resolved at hourly or sub-hourly granularity rather than typical-day approximation.
2. Shading
Row-to-row, near-horizon, and far-horizon shading loss — modeled multiple independent ways and benchmarked against what the simulator itself actually applies to the run.
3. Bifacial & Layout
Rear-side gain, ground-cover ratio, and tracker geometry — the design variables that most influence energy density per hectare.
4. India Regulatory [Exclusive to IST PVSolar]
Compliance and cost fields specific to the Indian regulatory and procurement environment, built into the workflow rather than left to a separate spreadsheet — the category most competitor tools (built for European/US markets) do not address at all.
5. Financial & Bankability
The outputs a lender's technical advisor actually asks for: exceedance-probability yield, sensitivity of returns to key assumptions, and a documented evidentiary trail.
6. Accuracy & Validation
How the platform's own outputs are checked — against field data, against an incumbent industry tool, and against themselves over time.
7. Multi-Currency Engine [Exclusive to IST PVSolar]
Currency is a single, global setting that propagates through every part, chart, and generated report — with proper locale-aware number formatting per market, not just a swapped symbol.8. Country/Region-Specific CAPEX/Wp Bankability Bands [Exclusive to IST PVSolar]
Installed cost per watt varies materially by country — labour, land, import duty and local EPC competition are not the same in Lagos as in Zurich. Rather than one fixed USD threshold, every currency carries its own editable low/high CAPEX/Wp band, tracked separately for utility-scale ground-mount and rooftop/C&I (rooftop runs structurally ~30–40% higher per Wp due to mounting complexity and smaller BOS economies).
9. Automated CAPEX Benchmark Verdict
The Bankability Assessment Report doesn't just display a project's CAPEX/Wp — it benchmarks that figure against the matching country/segment band and states a verdict in the report's own language.
10. Country, Political & Currency Risk
Content DFIs, ECAs and international lenders expect beyond the core technical/financial model, for projects where the lender's exposure is cross-border.
