Abstract
Five PV-Modules at different tilt angles were installed and connected to an automatic measurement equipment. The I/V-characteristics, temperatures and insolation values are continued to be measured in a two minute timesteps since autumn 1989. Stored into a database, all the data is available for detailed analysis. The results up to now include -tilt angle influence on energy yield and its annual course, -energetically weighted MPP voltage distribution and its annual course, -fixed voltage adaptation and best fixed voltage, annual and seasonal adaptation efficiency, -energy yield as a function of fixed voltage and tilt angle compared with MPP tracking at optimum tilt angle.
