Project of a 30 kW grid-tied solar power plant in Khmelnytskyi for the Sytyi Kovboy hotel and restaurant complex. Modern system components and an integrated approach to planning help ensure one hundred percent efficiency of the plant. The project used panels of two capacities: JA SOLAR JAM72D40-590/MB for 590 W and JA SOLAR JAM54D40-450/LB for 450 W, as well as a PROSOLAX X3-PRO 30K-G2 three-phase grid-tied inverter. The solar station not only provides a stable power supply for the hotel, but also helps to save on electricity.
