The photovoltaic system is very reliable. The probability of failure is low and typically affects dc / ac converters (inverters), while modules rarely fail. 5.2) What weight does maintenance have for a photovoltaic system? The weight of the maintenance is really light: on average one preventive maintenance visit per year is scheduled for some checks and checks (tightening of the panels and support structures; verification of the cleanliness of the modules with possible washing). It should be noted, however, that the best control operation consists in continuously reading the production data through a monitoring system , perhaps combining them with the relative weather data: a statistical comparison allows, in most cases, to easily highlight any anomalies. 5.3) What guarantee does a photovoltaic system enjoy? The main parts have different guarantees : normally the modules are guaranteed for 20 years with 80% efficiency and the dc / ac converters (inverters), depending on the manufacturer and type, are guaranteed for 5 to 10 years.
