Solar energy characterization, models of solar radiation for average and clear sky: use of "ad hoc" software. Pros and cons of Photovoltaics. Structure of the semiconductors: energy bands; doping; p-n junction and electric field; losses in the energy conversion. Spectral response and efficiency of the main technologies: single, multi-crystalline and amorphous silicon, Cadmium Telluride, Copper-Indium- Diselenide. Surface covering per installed kilowatt. Equivalent circuit of the solar cell, I-V and P-V characteristics at variable irradiance and cell temperature. Focus on an application problem: series/parallel connection of cells; I-V curve mismatch and shading effect; hot spots and breakdown; bypass and blocking diodes. Datasheets of the commercial PV modules, thermal coefficients of the electrical quantities. Calculation of the electrical parameters of the PV modules in ambient conditions different from the STC by datasheet of the manufacturers. DC-AC converters for the grid connection: Maximum Power Point Tracking (MPPT); active/reactive power control; interface protections; protections against over-current and direct/indirect contacts. Sizing of the components in a PV plant: coupling of PV array/inverter: power/voltage/current constraints. Costs of installed power and produced energy. Conventional calculation of energy production: causes of losses in the productivity, economic analysis by the Net Present Value (NPV). Automatic Data Acquisition System, typical testing procedure and experimental results on operating PV plants. Calculation of the energy production in a PV system.

ModalitÓ di esame:
Exam:
...
Gli studenti e le studentesse con disabilitÓ o con Disturbi Specifici di Apprendimento (DSA), oltre alla segnalazione tramite procedura informatizzata, sono invitati a comunicare anche direttamente al/la docente titolare dell'insegnamento, con un preavviso non inferiore ad una settimana dall'avvio della sessione d'esame, gli strumenti compensativi concordati con l'UnitÓ Special Needs, al fine di permettere al/la docente la declinazione pi¨ idonea in riferimento alla specifica tipologia di esame.
Exam:
In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
