How does a solar luminaire work?
convert solar energy into electrical energy. The latter is stored in the
battery. At dawn solar modules stop producing energy (no current), the
controller realises that it is dark and turns the light on. The light is turned
off as soon as solar modules start producing energy in the morning.
How long is a
solar luminaire working without daylight?
luminaires operate for 75 to 100 hours with full batteries.The controller stops
current supply to the LED as soon as the capacity of the battery gets lower
than 30% (remaining capacity) in order to secure the battery from a deep
What is the
maintainance interval for a solar luminaire?
We suggest to
clean the solar module and the LED module once a year. Battery has to be
replaced every five years. LEDs have a life span of 12 years.
How long does
it take to install a solar luminiaire?
installation time is 20-30 minutes per luminaire.
What is the
life span of the battery and who can replace it?
has to be replaced every five years. The reason therefore is, that the
remaining capacity is too low to guarantee a satisfying operation (expecially
in winter). Every technican is able to change the battery.
battery recycling organised?
return your battery directly to photinus. The German foundation
"Gemeinsames Rücknahmesystem Batterien" provides container to trader,
townships and all public entities for the returning of batteries. This is free
of charge. ERA-ELektroRecyclingAustria provides this service in Austria. 95% of
all lead-gel batteries are recycled.
What is the
life span of a solar luminaire?
years (depending on battery modell)
LED: 12 years
casing: 30 years
can be luminated?
official norms solar luminaires can illuminate minor and residential roads at
less than 30 km/h. These are especially the S-classes according to DIN EN13201.
In addition, all walk- and bicyle ways can be illuminated according to official
performance can be expected?
A decade of
expercience with solar lighting tought us, that we need a relation of 10:1
between the PV performance and the LED performance. One can ensure operation in
Middle Europe during winter only under these circumstances. This means:
performance equals 30W lighting performance. Photinus solutions range between
3-30 W lighting performance and between some 300 - 3000 lm luminous flux. Be
aware, that some competitor use values of summer operation in their data
use motion sensors?
motion sensors can be applied to all photinus luminaires in order to turn the
luminaires on and off. Please consider that the range of available motion
sensors is limited to 10 meters.
How does this
technology perform with a lot of snow?
energy towers are designed vertically, hence it is not possible that snow
remains on the solar modules. Due to the increased total radiation through
reflection the radiation to the solar luminaire is even higher at snowy
streetlighting work above the 48. latitude (Bregenz)?
luminaries already work above the 48. latitude for a number of years. Photinus
luminaires operate successfully in Moscow (55. latitude). Nevertheless, it is
not possible to use any luminaire at any place on earth.
are either fixed by using a screw fundament (Krinner) or by using a traditional
guarantee does photinus offer for its products?
