In the month of March 2015 Neven-SIG Solar has installed a hybrid system with 4 kW on the roof of a family home in Malka Vereya, municipality of Stara Zagora. The complete interior and exterior lighting, and socket outlets for TV, Internet, and other, are supplied with free energy from the sun. The modular design allows an increase in performance at any time.
The batteries of the energy storage system are loaded at daylight, and in the evening they provide the necessary electricity of the house.
The energy manager automatically controls the consumption and coordinates the energy flows from sun, wind or diesel generator. The external power supply system exists only as a backup source.
The study carried out on the 30.10.2012 of Jacobs University of Bremen, Germany, declares 1-th place for the LED products of the SiG Solar Group. In lab terms were checked all parameters by 80 manufacturers of LED lighting. Clearly higher results in comparison to all others have emphasized the leader with the testing of the effectiveness with maximum lighting angle and maximum lighting distance. It all lowest temperature of 24 degrees, at a 10-hour work, is also a record in the history of the light bodies.
