In the recent work entitled “An efficient analytical approach for obtaining a five parameters model of photovoltaic modules using only reference data” (Appl. Energy 111 (2013) 894–903), Lo Brano and Ciulla (2013)  proposed a set of five equations to be used in a resolution procedure for the identification of the five-parameter model of photovoltaic modules by starting from data available on datasheet at standard reference condition. Some comments about this work are discussed in the present letter to the editor.
