The following thesis deals with the energy production comparison between two different conversion technologies for photovoltaic systems: central-inverter conversion versus micro-inverter conversion. After an analysis over the many energy production systems, the thesis focuses on photovoltaic energy systems. The study of cell, module and system efficiencies will explain all causes of energy losses that can affect the photovoltaic energy generation. The second part of the thesis is focused on the micro-inverter technology and the differences with the central-inverter systems. Data analyses have been made on many systems in different locations (with almost the same sun radiation received), different azimuth and tilt angles, and different shading percentage. The analyses will show how micro-inverter systems can improve energy production not only during shaded but also in not-shaded conditions. At the end an economic comparison between the two different technologies will try to justify the use of micro-inverter systems not only for energy production efficiency but even for economic affordability.
La seguente tesi riguarda la comparazione nella produzione energetica di due tecnologie di conversione fotovoltaica: conversione con inverter di stringa o con micro inverter. Dopo un'analisi riiguardante le fonte di generazione energetica, la tesi si focalizza sulla fonte fotovoltaica. Lo studio delle efficienze di cella, modulo e sistema spiegheranno le cause di perdite energetiche che possono affliggere i sistemi fotovoltaici. La seconda parte si focalizza sui microinverter e le differenze rispetto l'inverter di stringa. Analisi sono state fatte su svariati sistemi con differenti caratteristiche di orientamento ed ombreggiamento. Le analisi mostreranno che i microinverter possono incrementare la generazione energetica sia nei casi di ombreggiamento, sia di non ombreggiamento. Infine una comparazione economica tra le tecnologie proverà a giustificare l'uso dei microinverter non solo per una efficienza energetica ma anche per una convenienza economica.

Abstract
The following thesis deals with the energy production comparison between two different conversion technologies for photovoltaic systems: central-inverter conversion versus micro-inverter conversion. After an analysis over the many energy production systems, the thesis focuses on photovoltaic energy systems. The study of cell, module and system efficiencies will explain all causes of energy losses that can affect the photovoltaic energy generation. The second part of the thesis is focused on the micro-inverter technology and the differences with the central-inverter systems. Data analyses have been made on many systems in different locations (with almost the same sun radiation received), different azimuth and tilt angles, and different shading percentage. The analyses will show how micro-inverter systems can improve energy production not only during shaded but also in not-shaded conditions. At the end an economic comparison between the two different technologies will try to justify the use of micro-inverter systems not only for energy production efficiency but even for economic affordability.File | Dimensione | Formato | |
