In 1986, a stand-alone PV system (1.344 kW peak) was erected by the Royal Scientific Society (RSS) in southern part of Jordan in a village called Gregra through a PV joint project supported by the German Federal Ministry for Economic Cooperation (BMZ) through the German Agency for Technical Cooperation (GTZ). Its main purpose is to supply electric power to the clinic which serves about one thousand inhabitants working in agriculture.
The PV system essentially consists of an adjustable-mounted 1.344 kWp PV-modules array (35 AEG PQ 10/40/01 PV modules connected in parallel), a 21.6 kWh storage lead-acid batteries and a locally manufactured charge/discharge controller.
The generated DC electricity is utilized in operating 35 low consumption lamps (12 V, 20 W, 900 lumens), a solar refrigerator (12 V, 197 liters, 60 W) for the preservation of vaccines and medicines, and an educational television (12 V, 80 W).
DC-decentralized PV system at Beer Mathkour clinic
The PV system in Gregra was followed by another stand – alone PV system erected in 1987 in the clinic of Beer Mathkour. This system consists of 538 Wp PV array (14 modules type AEG PQ 10/40/01), a 600 W charge regulator (type AEG BCR 12 Sh 600) and 7.2 kWh storage batteries. The generated DC electricity is utilized in the operation of low consumption lamps (12 VDC, 15 W, 800 Lumens), an educational television (12V, 50 W) and a solar refrigerator (60 W, 197 liters) for the reservation of medicines and vaccines.
DC-decentralized PV system at Ma’mora clinic
The stand-alone PV system of this clinic which was erected by the RSS in 1990 and financed by the Ministry of Health, consists essentially of 1100 Wp PV array (22 modules type Siemens SM 50-18 A2), two locally developed charge/discharge battery controllers, and 16.8 kWh storage batteries (type Sonnenshein). This PV system supplies electrical energy to 26 low consumption fluorescent lamps (24 V, 20 W) and a refrigerator for the reservation of medicines and vaccines
The operation experience of this system indicates complete compliance with design requirements and expectations
Reesheh AC-decentralized photovoltaic power plant
In general electrical equipment is designed and manufactured for utility network connection (220 V, 50 Hz). Therefore the output block usually should include an inverter in order to feed the load with a single phase AC voltage at 50 Hz.
As an application for that, a stand-alone AC decentralized PV system for residential applications was installed in March 1988 at the medical center of Reesheh. This system has four main components, namely the 3.072 kWp PV array consisting of 80 modules (type AEG PQ 10/40/01), a storage battery block of 1800 Ah capacity at 48 V, a 5 kW Sun Power DC/DC converter with a maximum power point tracker and a 48 VDC/220 VAC, 5 kW single phase inverter. The generated power is utilized in the operation of the medical center available loads such as refrigerators, lights, televisions and other laboratory equipment.
Photovoltaic power supply for remote schools
In 1993, 6 identical stand-alone PV systems were designed and erected by the Royal Scientific Society in the southern part of Jordan in five remote villages namely, Beer Mthkour, Wadi Rum, Finan, Titen and Al-Mizfur. The main objective of this project which was financed by the Ministry of Education, is to supply electric power to schools and the teacher’s residences.
Each PV system consists essentially of an adjustable-mounted 200 Wp PV modules ( 4 Siemens SM 50 PV modules), electrically configurated in 2 parallel string with 2 series connected modules in each string, a 4.8 kWh storage lead-acid batteries and two charge/discharge controllers type Helios
The generated DC electricity is utilized in operating 10 locally manufactured low consumption lamps (24 V, 20 w, 1000 lumens), an educational television (12 V, 15 W) and finally educational cassette recorder. With the installation of such systems, the dependence of the teachers on the dim kerosene lamps was eliminated.
Photovoltaic power supply for remote police stations
The Royal Scientific Society (RSS) and the Public Security Department undertook in 1991, a joint project regarding the utilization of PV technology, instead of diesel generators, for the electrification of Al-Salamani police station. The PV system which was designed and erected in January 1992 for the electrification of this station proved good performance and high reliability through the two-year period of continuous tests.
Following the success of this experiment, the RSS was assigned the duty of studying, designing and electrifying all the 35 remote police stations during the next years
The first stage of this project which included the electrification of 6 stations namely, Umari, Hazeem, Weasad, Husaida, Anqa and Al-Heaber, was thoroughly fulfilled in the second half of 1993.
Each of the 6 identical PV systems consists of 742 Wp array (14 modules type Siemens SM 55), a 13.2 kWh storage lead-acid batteries manufactured by Fulmen/France, a 1 kW locally manufactured charge /discharge controller and 2 DC/AC inverters (24V DC / 220V AC. The generated AC electricity is utilized in 13 lamps , a locally manufactured refrigerator (24 VDC, 100 W, 230 liters) and a TV
The second stage of this project which implies the electrification of the 6 stations, namely Headalah, Roqban, Boastana, Al-Artean, Al-Mashakek and Al-Sagriat was implemented in 1994
The 6 systems are mostly identical. Each of them consists of 945 Wp array (18modules type Siemens SM 55), a 13.2 kWh storage lead-acid batteries manufactured by BP, a 1 kW locally manufactured charge /discharge controller and 2 DC/AC inverters (600W,24V DC / 220V AC each). The generated AC electricity is utilized in 20 lamps , a locally manufactured refrigerator (24 VDC, 100 W, 230 liters) and a TV
The third stage was implemented in 1997 for the electrification of another 6 locations : E’nazeh, Al-Matwy, Bayer 1, Bayer 2, Meshash Hodroge, Al-Ennab. All systems are identical and same as the systems of the second stage
As a result to the fact that electrical loads are designed and manufactured for utility network connection (220 V, 50 Hz), each of the 6 new systems includes a 600 VA Dc/AC inverter in addition to a 742 Wp PV generator, a 13.2 kWh storage batteries and a1000 W locally developed charge/discharge controller
Photovoltaic generators for the Non-Directional Radiobeacon (NDB) systems
In 1988 the Civil Aviation in cooperation with the Royal Scientific Society (RSS) had set up two identical PV-powered non-directional radiobeacon (NDB) systems in two remote villages, namely Al-Reesheh and Rahmeh which are located in the southern part of Jordan at a distance of about 80 and 50 km respectively from Aqaba airport. The main purposes of these systems is to identify these sites to the planes flying to Aqaba airport
Each system consists of 40 PV modules (type Arco M55) with a total power of 2.16 kW, a charge/discharge battery controller, a battery block of 1250 Ah at 48 VDC, a static inverter (48 VDC/110 VAC, 60 Hz), two transmitters each 50 W, a transfer unit which allows either transmitter to be considered as the primary one while the remaining transmitter in a standby status, an antenna coupler and finally a 90 foot guyed mast antenna.
Photovoltaic generator for the railway radio communication systems
Several radio communication systems are located along the railway between the phosphate mines in Al-Hassa and Aqaba seaport. Each one of these systems is powered by two diesel generators each running continuously for 12 hours/day.
In 1985 one of these stations, namely Fian (25 km to the north of Aqaba) was electrified by a PV system. This system consists of 44 polycrystalline PV modules (1.76 kWp) type photowatt, a 19.2 kWh storage batteries, and a 2 kW locally developed battery controller.
There are many other different applications such as :
