This system is composed by special innovative lamps of new
generation and very low consumption, developed and
manufactured by Istar Solar® after many
years of studies and researches in the field of high
intensity Led lighting. These lamps are powered by
photovoltaic modules.
The big advantages of this system like : the complete independence
from grid, the lifetime of lamps (100.000 hours 22 working
years!), the long lasting of photovoltaic modules (over 30
years), low working voltage (12VDC) so not dangerous, no need of
works for excavations and cables connections, very white
light and low consumption, no maintenance, no bills to pay,
etc… make the cost of the whole system amortizable in just few
years, with a high profit.
Additional information on cost reductions and pay-back time of the
system, can be found on the comparative table.
The completely autonomous functioning makes the system very
efficient: during the day the modules charge the batteries (sized
for 3 days of autonomy no sun) and in the evening the charge
controller Rigel™12 (manufactured by Istar
Solar®) with built-in morning light function switches on
the lamps that will be switched off automatically at sunrise for 12
hours per night.
With this built-in function there is no need to install an external
morning-light function.
Moreover, with this charge controller it is possible to set up the
switch on of lamps up to a maximum delay of 2 hours after sunset.
