Stand-Alone Photovoltaic Systems for Telecommunication Stations, a Case Study for Kahramanmaras, Turkey

Abstract

Telecommunication is one of the areas that photo voltaic solar systems are used. TURKTELEKOM radio link station located in Sulutarla (K: 37.62629649, D: 36,92422807, Altitude: 1367 m) operates with solar energy. 24 pieces of 350 Ah OPzV gel batteries were used in system. Each piece of battery is 2,25 V and connected in series. Total battery voltage is 54 V. Photovoltaic panel power is 85 W and 12 pieces of monocrystalline panel are used in system. Output voltage is 21.6 V and panels are installed in 3 series, 4 parallels. With a total power of 1,08 kWp Stand-alone PV system takes 7,8 m2 area and generates 1763 kWh energy per year. System performance ratio is 81 percent. Telecommunication stations located away from grid solve energy problem economically with solar energy.
