A photovoltaic PV installation is exposed to extreme ambient conditions due to the solar radiation, humidity, wind and thermal stresses. A comprehensive design of its power system could follow two complementary strategies: one consisting in the adoption of special components and the other one consisting in an adequate installation of standard components providing a continuous control of its operation life cycle. At this aim the paper suggests to subdivide the DC wiring system in a final distribution to the panels with high stress exposition, wired by special solar cables, and a main distribution as much as possible with an installation avoiding the stress exposition, wired by normal cables and monitored by a “counter hours program”. This program evaluates and monitors the real thermal aging of the main wiring system and could be a tool integrated in the supervisory system.

Abstract
A photovoltaic PV installation is exposed to extreme ambient conditions due to the solar radiation, humidity, wind and thermal stresses. A comprehensive design of its power system could follow two complementary strategies: one consisting in the adoption of special components and the other one consisting in an adequate installation of standard components providing a continuous control of its operation life cycle. At this aim the paper suggests to subdivide the DC wiring system in a final distribution to the panels with high stress exposition, wired by special solar cables, and a main distribution as much as possible with an installation avoiding the stress exposition, wired by normal cables and monitored by a “counter hours program”. This program evaluates and monitors the real thermal aging of the main wiring system and could be a tool integrated in the supervisory system.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
