The design of a photovoltaic installation is possible through the use of specialized software. Simulation programs allow the optimization of the PV installation, as well as the evaluation of the expected effects and the designer's assumptions. Examples of programs used for PV plant design are:

• PV*SOL,
• Polysun,
• Easy Solar,
• PV Designer,
• PV Manager,
• Blue Sol,
• Fronius Solar Configuration.

These programs are dedicated to designers of photovoltaic installations, as well as architects or installers. The programs can also be used as a teaching or learning aid for university students. The Photovoltaic Laboratory at the Department of Computer Science, Electronics and Telecommunications at AGH University of Science and Technology is equipped with two specialized programs for designing photovoltaic installations. These programs are PV*SOL and Polysun - used by designers all over the world.
