Initial situation and requirements

Solar power is one of the fastest growing sources of global energy today. PV modules with different physical performance characteristics are used to harness energy at locations around the world. Climates and mounting requirements vary among locations. These variations in operating conditions have a direct link to energy yield and power plant profits.

Watch our video below which explains why minimal measurement uncertainty is desired when it comes to PV modules.

Because software simulation tools are not always as reliable as expected, performance and durability must be tested in the field to validate an individual PV module technology suitable for a particular climate environment.


Solutions and results

The TÜV Rheinland PV Climate Project resulted in the reliable comparison of different PV modules operating under changing climate conditions specific to various environments around the world.

Our specialists gathered climate data in 4 countries – Germany, India, USA, and Saudi Arabia – over a period of up to 4 years, and were able to determine the stability of electrical parameters and the STC power of individual PV modules during operation.
