CUF Analysis

Capacity Utilization Factor (CUF/PLF)

CUF is the percentage of actual energy generated compared to a plant’s maximum possible output over time.

Calculate CUF

Degradation & Insolation Corrected CUF

It adjusts plant performance by accounting for solar module degradation and varying solar insolation over time.

Calculate Advanced CUF

Yield and PR Tools

Specific Yield & Performance Metrics

It assesses solar plant efficiency using Specific Yield, Reference Yield, and the Performance Target Index (PTI).

Calculate Specific Yield

Capacity Based Performance Ratio

It evaluates actual plant performance using measured energy, DC capacity, and plane-of-array insolation.

Calculate PR

Efficiency Based PR

It measures how efficiently a solar plant converts solar energy into electricity based on panel specs and area.

Calculate PR

Instantaneous PR

It monitors real-time performance ratio using current irradiance, power output, and plant capacity data.

Calculate PR

Temperature Corrected PR

It adjusts the performance ratio to account for temperature effects on solar plant efficiency.

Calculate PR

Soiling Analysis

It estimates energy yield losses caused by accumulated dust, dirt, and debris on solar panel surfaces over time.

Calculate Soiling Loss

Plant & Grid Generation Loss

It estimates energy losses in your solar system by analyzing inefficiencies in both plant generation and grid delivery.

Calculate Generation Loss

Plant Monitoring and Irradiance Tools

Plant & Grid Availability

It estimates plant and grid availability by measuring downtime against available solar radiation during the period.

Calculate Availability

Insolation Synthesis

It estimates solar insolation by combining your plant’s energy output, capacity, area, module efficiency, and performance ratio.

Calculate Insolation

NMGG Calculator

It accurately derives monthly net target generation figures using annual NMGG and monthly expected Insolation POA.
