A 29 kWp PV power station, with lead-acid battery storage, was installed in Tunisia in 1982[1]. It worked continuously during 20 years to supply a remote village, Hammam Biadha, with electricity (220 V, 50 Hz). It has been disconnected in 2002, when the national grid reached the village. We have been measuring the PV properties of the 840 panel of the station during sunny days of June and July 2007, in goal to study the possibility of recycling the good panels to make a new power station connected to the grid [2]. This communication gives the results of this study. The most important defect was seen in the connecting cables and plugs; their insulation was de-polymerized and falls down in powder, the copper, for some cables, is no longer insulated. We present here the preliminary results of our study
