Abstract
The electrical energy generation by renewable sources has been one of the most significant means of energy production expansion worldwide. Among the available renewable sources, solar photovoltaic energy has taken an important role in this process. In Brazil, the implementation of photovoltaic energy generation systems, considering micro and mini generation, like global tendencies, grew considerably since 2012 after the regulation established by the national energy regulatory agency. Such increasing implementations means a bigger diversification of the energy sources of the country, which leads to enlargement of the national power generation and to benefits for those who invest in these solutions. However, an increasing number of fire incidents related to PV systems has been observed as well. This scenario leads to the augmentation of fire investigations related to PV systems, which it will demand a more refined knowledge of the criminal expert (or fire investigator) regarding the local inspection, the collection of data and evidence and its analysis. Therefore, this work aims to provide a bibliographic survey about failure modes in grid connected PV systems that may cause fire or could be related to it. Additionally, from these identified failure modes, it will be recommended some specific procedures to be performed in PV related fire sites to look for evidence that points the origin of the incident towards to the PV system.
