Solar Tree
Structure composed by curved steel poles
of different diameters and heights, with a maximum
total height of about 5,5m over road level.
This system is composed by 10 “stems of grass”
with 40mm Ø. On their extremity there is 1 LED
of about 1 W protected by a diffuser screen
in PETG and 10 poles with 76mm Ø supporting
the heads.
The poles are painted with outdoor epoxy
paint in light green colour shading into white.
The 10 heads, housing the photovoltaic cells in their
upper part, are supported by poles with a diameter
of 76mm; 20 power LEDs, which can be supplied
with power up to 500mA and have a white neutral
colour temperature, are housed in the lower part
of 4 of them, on an aluminium dissipator, and
are provided with a screen in plastic material which
ensures protection against water and dusts.
The base is made of hot-galvanized steel plate
to be fixed to the ground. Otherwise it is possible
to use a base, always in galvanized steel, with
reinforced concrete parts forming a circular bench.
In this case the base can rest on the ground without
need of further fixing systems.
The connection/wiring parts, the control and
recharge boards and the batteries are contained
in several watertight boxes, provided with male
and female connectors with IP Rating IP65 or higher,
placed at the foot of the base or inside the concrete
bench, according to the technical specifications
of the Solar Tree version supplied.
Benches in white painted concrete, with second
coat of anti-graffiti paint.
Ein = ∑ Ppeak power • hequivalent • hsystem • hnoct • htilt angle
Ppeak power = Maximum power input
hequivalen = Average received solar radiation in hours
hsystem
= System conversion efficiency
hnoct
= Nominal operating temperature
htilt angl = Exposure factor
Configuration
The light fitting configuration includes an analysis of
the potential incoming energy (geographical location
of the light fitting) and a detailed analysis of the
physical location of the light fitting (proximity of
buildings or trees). Lastly, an analysis of the level of
requested service and performance will be imple-
mented (luminance levels, operation hours, potential
discontinuity in the service, if any).
