PVSYST TRAINING PVSYST Usage for Grid Connected Systems
OBJECTIVES Understand the impact of solar irradiation on PV production. Present the characteristics and results of the standard diode model, and its extension to all the technologies. Characterize the components of a PV system and optimize its design. Design a complete project using PVsyst. Quickly size a system to prepare a budgetary quotation. Better use PVsyst to design various PV systems. Design a large PV system in the fields with fixed modules or sun trackers.
TARGET AUDIENCE PV design engineers, PV installers (with experience), PV project managers, teachers.
PREREQUISITE Good electricity knowledge, Basic knowledge of PV designs and technologies, Knowledge of PV market and industry, Bases on the electrical behavior of a PV panel and a PV field, Bases on inverters and their operation, To have already designed or realized one or several PV systems..
PRESENTATION Printed presentation, USB-key with extra documentation and a copy of the presentations, PVsyst software for the duration of the training.
NECESSARY HARDWARE Participants should bring a portable PC working under windows.
SPEAKERS André Mermoud – PhD Physicist, author of the PVsyst software, study of Energy and PV systems at the University of Geneva (CUEPE, Energy Group). Michel Villoz – Electrical engineer EPFL, more than 30 years experience in PV component fabrication and PV design.
INFORMATIONS The PVsyst software uses an extended knowledge of PV technology, meteorological irradiation resources and PV components. However it cannot replace the user's expertise. It is a tool for deeply understanding PV systems and optimizing their design. Therefore this training proposes an important part of theoretical concepts. This course does not propose information about the PV industry or on standards and regulations. It does not either provide any administrative or bureaucratic constraints, commercial, economical or legal aspect for the design of a project.
