How to Find Performance Ratio (PR)?

Performance Ratio (PR) of a plant for a period of time is energy measured(kWh)/(Irradiance(kWh/m2) on the panel x Active area of PV module(m2) x PV module efficiency).

What is performance ratio PR?

performance ratio (PR) is the ratio of measured output to expected output for a given reporting period based on the system name-plate rating. performance index is the ratio of measured output to expected output for a given reporting period based on a more detailed model of system performance than the performance ratio.

What is performance ratio in solar PV?

The performance ratio from mathematical calculations of the floating PV system is 80.24% and the rooftop PV system is 73.41%.

How to calculate PR from PVsyst?

- Ls = System Loss = Ya - Yf, include inverter loss in grid-connected systems, or battery inefficiencies in stand-alone. - PR = Performance Ratio = Yf / Yr, is the global system efficiency with respect to the nominal installed power and the incident energy.

How do you measure solar panel performance?

Finally, to calculate the maximum efficiency of the solar panel we need to divide the ratio of panel power to sun power by the area of the panel in square meters, then times by 100 to get a percentage.
