kWh Québec — Market Intelligence & Methodology Updates

Rule

Always update the Market Intelligence and Methodology sections when new information is received or new methods are applied to the platform.

When to Update

• •New supplier pricing data is added or updated
• •Component catalog prices change
• •New analysis methods or calculation improvements are implemented
• •Solar yield estimation methodology changes
• •Financial calculation formulas are modified (NPV, IRR, LCOE, etc.)
• •New tariff data from Hydro-Québec is integrated
• •Battery or peak-shaving algorithms are updated
• •Monte Carlo simulation parameters change
• •Benchmark calibration data is updated
• •PVSyst system loss parameters are modified

What to Update

• •Market Intelligence (/app/market-intelligence): Supplier prices, component pricing, market trends, competitive data
• •Methodology (/app/methodology): Analysis approach, calculation methods, data sources, assumptions, validation procedures

Where the Data Lives

• •Pricing components: pricing_components table
• •Supplier data: suppliers table
• •Price history: price_history table
• •Component catalog: component_catalog table
• •Analysis parameters: shared/schema.ts (defaultAnalysisAssumptions)

PVSyst Calibration Baseline (Feb 2026)

The analysis engine is calibrated against Rematek PVSyst reports for Montreal-area C&I projects. Key calibration points:

• •System loss budget: ~5.4% net derate (wire 3%, LID 1%, mismatch 2.15%, quality gain -0.75%)
• •DC:AC ratio: 1.45 (PVSyst range 1.44–1.47)
• •Bifaciality: 0.80 factor, 0.60 albedo (conservative)
• •Effective net yield: ~1,030 kWh/kWp after all derates + temperature correction

When modifying any yield or loss parameters, the methodology page must reflect the change and note the PVSyst validation source.
