Summary / Abstract: The objective of this study is to monitor the performance evolution of hundreds of domestic PV installations in different environments and climatic conditions in order to determine the degradation rate and see the influence of climatic conditions on the performance of domestic PV installations. Output data recorded from 2613 rooftop domestic PV installations of two technologies (mono and polycrystalline silicon) in France in six different regions (Table 1) and collected in the BDPV site [1] are treated here. The selected domestic PV installations for this study have a peak power above 2 kWp and have been operational for at least more than 3 years. A maximum number of PV installations was considered according to the available data. The main criterion used is the performance ratio given by equation (1) [2] based on the "Performance to Peers" (P2P) method [3], which is constructed by comparing the performance ratio data of several neighboring PV systems. P2P allows, as far as possible, to distinguish between normal and faulty operations, and each PV system to be analyzed is called focal PV system. The process of developing the guideline is structured around three main steps. First, it determines which neighboring installations are the reference and also quantifies their relative quality as peers. Second, the P2P is built from comparisons between the energy production of the focal installation and that of its peers. Thirdly, P2P is applied to the detection of defects that signify degradation.
