Free Online Plant & Grid Generation Availability Calculator

This calculator estimates the plant and grid availability of your solar power system by identifying downtime relative to available solar radiation during the calculation period, helping to improve overall performance.

  1. Enter the Insolation During Outage in kWh/m2. This represents the amount of solar energy received during the outage period.
  2. Input the Plant Capacity Under Outage in kW. This refers to the non-operational capacity, and not the installed plant capacity.
  3. Provide the Plant Area Under Outage in square meters (m2). This refers only to the area of non-operational capacity, not the area of installed plant capacity.
  4. Specify the Module Efficiency as a percentage. The efficiency typically varies from 10% to 40%, based on the type of solar panels and the age of the plant.
  5. Enter the Average Performance Ratio (PR) in %. Input the average performance ratio of the solar plant, considering its optimal operational efficiency and age of the plant.
  6. Enter the Actual Energy Produced (kWh). It is the actual plant generation in kWh.
  7. Calculate to get the Plant or Grid availability. Use this insight to optimize your system performance.

This tool helps you assess plant and grid availability based on solar radiation by identifying periods of downtime caused by outages, maintenance, or transmission issues. Use these insights to make informed decisions and enhance system reliability and energy yield.
