What Is a Solar IV Curve Test?

The Solar IV (Current-Voltage) Curve Test is a diagnostic procedure used to evaluate the electrical performance of photovoltaic panels. By measuring the current (I) and voltage (V) at different loads, this test creates an IV curve that represents the solar panel's efficiency and operational limits.

The Solar IV Curve is essential in the development of solar PV cells, providing insights into a solar cell's performance, energy conversion capability, and overall efficiency.

This curve is essential for solar energy manufacturers as it reveals crucial performance parameters, including maximum power output (Pmax), open-circuit voltage (Voc), short-circuit current (Isc), and fill factor (FF).
