How many times have you seen the lights of street lamps lit during the day? This happens because in the traditional management of lighting, it is a twilight photocell that decides the switching on and off of the lights. Often, however, the photocell is dirty or faulty, causing unwanted ignition and consequent energy waste.
With the astronomical clock this problem is definitely solved. By setting latitude, longitude, time zone, civil twilight value of the system, all the lights come on and off simultaneously at the right time all year round, saving up to 8% of energy.
