Experience from PV system performance (including comparison of on-roof and façade systems in Prague) Vitezslav Benda, Zdenek Machacek CTU Prague, Faculty of Electrical Engineering

radiationtemperature datalogger In the year 2001, a 3kW p demonstration, on-grid connected photovoltaic system has been built at the Czech Technical University in Prague on the roof of the Faculty of Electrical Engineering.

Installed peak power: 3320 W p Total module area: 26 m 2 Number of modules: 30 (3 fields of 10) Latitude: ° N Altitude: 205 m

A comparison of estimated and measured energy production in period from January 2002 to December 2005

Energy produced by individual PV fields in period from January 2002 to December 2005

This gives the efficiency decrease of about 0.6% per 1K, which is higher than supposed decrease of cell efficiency (about 0.4% per 1K). It means that an increase of losses with increasing temperature in other parts of system cannot be neglected. Temperature dependence of energy conversion efficiency

August January

Temperature distribution over the PV field areas roof facade June, ambient temperature 32 °C Tilt angle: 45° Tilt angle: 90°

Temperature distribution over the PV field areas December, ambient temperature -6 °C roof

Shadowing effect PV field 1 PV field 2

Conclusions Facade PV system applications can produce about 66% of electrical energy produced by the roof (45° tilted) one Efficiency of PV systems is strongly influenced by temperature PV field constructions should allow an effective cooling of PV modules
