Generation Metrics
Quantify energy output relative to installed capacity and solar resource.
CUF / PLF
Standard CUF calculator using actual energy, installed DC capacity, and period hours. Used for PPA compliance and monthly O&M performance tracking.
Open CalculatorSpecific Yield & Performance Metrics
Calculates Specific Yield (kWh/kWp), Reference Yield (peak sun hours), and Performance Target Index (PTI) per IEC 61724-1.
Open CalculatorNMGG Calculator
Derives monthly Net Minimum Guaranteed Generation targets proportionally from annual NMGG using POA insolation distribution.
Open CalculatorDegradation & Insolation Corrected CUF
CUF adjusted for accumulated module degradation and deviation from design-year insolation. Fair performance benchmark for plants beyond year 3–4.
Open CalculatorPerformance Ratio Analytics
Evaluate plant efficiency under measured irradiance using IEC 61724 methodologies.
Capacity Based PR
Performance Ratio calculated using net AC energy, installed DC capacity, and plane-of-array insolation. Standard method for utility-scale O&M contracts per IEC 61724-1.
Open CalculatorEfficiency Based PR
Performance Ratio using module nameplate efficiency and total panel area — correct method when DC capacity figures are uncertain or unavailable.
Open CalculatorInstantaneous PR
Real-time Performance Ratio for fault detection during stable irradiance conditions or short-duration performance analysis.
Open CalculatorTemperature Corrected PR
PR normalized for cell temperature effects using the module temperature coefficient, enabling fair comparison across seasons and climates.
Open CalculatorDiagnostic & Corrected Analytics
Identify losses from soiling, equipment inefficiency, and string-level faults.
Soiling Analysis
Quantifies cumulative energy loss between cleaning cycles to determine commercially optimal cleaning frequency.
Open CalculatorInverter Efficiency
Upload CSV or Excel data to batch-analyze DC-to-AC conversion efficiency across up to 5 inverters, with per-device stats, charts, and exports.
Open DashboardSolar Panel Efficiency
Enter datasheet values to get STC, NOCT-corrected, and real-world operating efficiency plus Performance Ratio.
Open CalculatorString Current Deviation Calculator
Compares PV string currents in the same combiner box or MPPT channel to flag suspected blown fuses, shading, soiling, and underperforming strings.
Open CalculatorAvailability & Loss Analytics
Track equipment downtime and quantify lost generation from outages and curtailment.
Plant & Grid Generation Loss
Estimates lost generation in kWh from equipment failures or grid curtailment based on irradiance during downtime period.
Open CalculatorPlant & Grid Availability
Availability calculated against irradiance-weighted hours per IEC 61724-1 — correct method for O&M contract compliance and SLA verification.
Open CalculatorSolar Resource Analytics
Estimate solar irradiance when direct pyranometer readings are unavailable.
