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.
