## What is Photovoltaic solar panel?

Solves the simplified equation of the photovoltaic module with a single exponential and five parameters, from the test data (Voc, Vmp, Isc, Imp) of the photovoltaic panel under standard test conditions (STC: 1000 W/m² of irradiation, 25ºC cell temperature, spectrum AM 1.5g) provided by the manufacturer.

The determination of the parameters of the module allows to simulate the behavior of the photovoltaic panel under different conditions.

· Series resistance (Rs)
· Shunt resistance (Rsh)
· Fill factor (FF)
· I-V Curve, STC
· P-V Curve, STC
· I-V Curve, Irradiance, Temperature
· P-V Curve, Irradiance, Temperature
· Comparative two modules

## Key features

- Single exponential equation solver
- Five parameter determination
- Simulation under different conditions
- I-V and P-V curve generation
- Comparative module analysis
