Free Online Plant & Grid Generation Loss Calculator

This calculator helps you estimate energy losses in your solar power system by analyzing inefficiencies during both generation (within the plant) and delivery (through the grid). Accurately identifying these losses enables better diagnostics and performance optimization.

  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. The Irradiance at STC (kW/m2) is typically 1 kW/m² and this calculator takes it by default.
  7. Calculate to get the estimated Generation Loss %. Use this insight to optimize your system performance.

This tool helps you assess energy losses at both the plant and grid levels—due to outages, transmission issues. Leverage the insights to make informed decisions and maximize energy yield.
