<dc:description>La seguente tesi riguarda la comparazione nella produzione energetica di due tecnologie di conversione fotovoltaica: conversione con inverter di stringa o con micro inverter.&#xd;
Dopo un'analisi riiguardante le fonte di generazione energetica, la tesi si focalizza sulla fonte fotovoltaica.&#xd;
Lo studio delle efficienze di cella, modulo e sistema spiegheranno le cause di perdite energetiche che possono affliggere i sistemi fotovoltaici.&#xd;
La seconda parte si focalizza sui microinverter e le differenze rispetto l'inverter di stringa.&#xd;
Analisi sono state fatte su svariati sistemi con differenti caratteristiche di orientamento ed ombreggiamento.&#xd;
Le analisi mostreranno che i microinverter possono incrementare la generazione energetica sia nei casi di ombreggiamento, sia di non ombreggiamento.&#xd;
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.</dc:description>
<dc:description>The following thesis deals with the energy production comparison between two different conversion technologies for photovoltaic systems: central-inverter conversion versus micro-inverter conversion.&#xd;
After an analysis over the many energy production systems, the thesis focuses on photovoltaic energy systems.&#xd;
The study of cell, module and system efficiencies will explain all causes of energy losses that can affect the photovoltaic energy generation.&#xd;
The second part of the thesis is focused on the micro-inverter technology and the differences with the central-inverter systems.&#xd;
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.&#xd;
The analyses will show how micro-inverter systems can improve energy production not only during shaded but also in not-shaded conditions. &#xd;
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.</dc:description>
