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 South South East (favorable).
The plant works therefore at 95% of the optimum in France
(full south and slope 30°) as shown in the array below

INSTALLED
POWER
The South face of the roof spreads on a length of 23 m and a height of
7 m, of which 6,5m exploitable and will be equipped by Imerys photovoltaic
tiles of 55 Wc on a surface of 144 m², either a power of about 15.84 kW
peak
(kWp) considering the 2009 photovoltaic outputs "from the cell to the network" (110 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 an alternative power converter of 100 kVA lately
installed in the village by EDF.
RELEVANCE
OF THE ALTITUDE OF THE SITE
The middle
cloudy cover is comparable to the one seen in plain in the same region. On the other
hand, the inclemencies are there more abundant and will better clean the
photovoltaic panels. Besides, the high
altitude of the site
(1200 m) allows a cooling of the photovoltaic tiles and a
slightly more intense incidental solar radiance than in plain, both
beneficial for the output.
INTEGRATION
TO THE LOCAL ARCHITECTURE
By the choice
of the Imerys photovoltaic
rooftiles of small size and in the same color that the local blue
lauses [local traditional tiles], and by the uniformity waited for the roofing, the project
respects the mind and the colors of the local architecture while
adapting it to the clean and modern energies.
