The roof presents a slope of 50° characteristic of the local
construction destined to unload the framework of the wintry falls of
snow while permitting a substantial fodder storage volume in the
farming context of the old time. This slope encourages the natural
cleaning of the tiles with the inclemencies, and therefore the
best
impact of the solar rays on the photosensitive cells.
Orientation is full South (very favorable). The installation functions therefore to 95% of the optimum on France
(full south and slope 30°) as the array indicates it below

INSTALLED
POWER
The South face of the roof spreads on a length of 12 m of which 10,5m usable, and a height of
7.5 m, of which 7.1 m exploitable. It will be equipped by 70 photovoltaic panels Kyocera FD135GH-2P on a surface of 74 m², either a power of about 9.45 kW
peak
(kWp) considering the present
photovoltaic outputs "from the cell to the network (125 Wp /
m²)."
CONNECTION TO
THE EDF NETWORK (EDF : Electricité de
France)
The electric line is on the right in background and is located unless
50 m of the building as well as the power converter of 100 kVA lately
installed in the village by EDF.
RELEVANCE
OF THE ALTITUDE OF THE SITE
The middle
cloudy cover is very
comparable to the one seen in plain in the same region. On the other
hand, the inclemencies are there more abundant and will clean the
photovoltaic panels better. Besides, the raised
altitude of the site
(1200 m) permits both a cooling of the photovoltaic panels and a
slightly more intense incidental solar radiance than in plain, all two
beneficial for the output.
INTEGRATION
TO THE LOCAL ARCHITECTURE
By the choice
of photovoltaic panels of large size with white squared features, in
the aesthetic extension of the facade made of roughcast traditional,
the project
respects the appearance of the neighboring buildings which are covered
with sheet metal, while
adapting them to the clean and modern energies.
