The economic yields of photovoltaic systems are significant, but to ensure that those yields give the expected gain in a long-term investment is fundamental to program a series of operations maintenance and verification that maintain constant efficiency over time ensuring a return on investment that otherwise could be reduced from 7% to 15% over the years.
Below is a graph showing the decline in annual production from 1st to 3rd year of the life of a plant in northern Italy, due to lack of routine maintenance.
Sinergi S.r.l. proposes a number of packaged: from the simplest to the most complex that can be customized by the owners of photovoltaic systems in accordance with the needs identified.
Maintenance services selected or customized will be evaluated economically on the basis of location, accessibility, type and size of the PV. In this respect, once selected the desired services, the plant owner will receive a personalized contract proposal with its annual economic computation.
This is the service of cleaning and visual inspection on the status of the modules, on clamping of the modules fixed on the structures, on any string boxes and external components, on all wiring and connections in the external sections of the generator (modules) up to the electric meter of the PV system.
This service involves the verification of deposits of dust and other blackout substances on the modules and they are cleaned using the appropriate cleaning agents or through controlled jet of water (according to the different characteristics of the system and modules).
Provides that, where the implant is fitted with system monitoring and analysis, a series of electrical tests using instrumentation who report the indexes of productivity, performance and efficiency of all the electronic parts of the PV system by comparing each year resulting values.
Provides carry out inspection and cleaning group or groups inverter with checking and replacement of any filters or cooling fans and wear parts. In control step are verified eventual alarms and historical yield values of the machines.
Foresees the taking in charge of all the annual reports of the PV system owner and the GSE, the AEEG, the Customs Agency and ENEL
Foresees the possibility of connect remotely to one of our technicians to a prearranged system of the PV system at any time. The modalities and program of regular monitoring and alarm verification are defined in the contract.
