1 1 Eng. Firas Alawneh Head of Photovoltaics (PV) Division National Energy Research Center (NERC) Royal Scientific Society (RSS) Amman-Jordan Photovoltaic Applications

2 Outline Types of PV Systems –Standalone “off-grid” –Grid connected “on-grid” NERC’s PV projects implemented in Year NERC’s PV projects in progress. 2

3 3 Types of PV Systems Standalone “off-grid” Grid-connected “on-grid” Without storage With storage Hybrid Systems directly connected to the public grid connected to public grid via house grid Motors “e.g. pumps” DC Systems AC Systems with wind turbine with diesel generator with public grid backup

4 4 Off-grid / Without battery storage / Direct-coupled DC system PV Array DC Load

5 5 Solar Water Heaters Off-grid / Without battery storage / Direct-coupled DC system

16 16 Off-grid / With battery storage / Hybrid System PV Array PV Inverter Battery DC/AC Inverter AC Load Other Source Power Conditioning Unit AC-Coupled Grid Former

17 17 Inverters Off-grid / With battery storage / Hybrid System AC Bus (3-phase) Hybrid Solar/Wind/Diesel AC-Coupled

18 18 The grid is the network of cables by which electricity is transported from power stations to houses, buildings & other places. A grid connected PV system is linked to this grid or electrical network. This means that it can deliver the electricity it produces into the electricity network and therefore no battery or other storage is needed. On-grid PV Systems

19 19 On-grid PV Systems

20 BLOCK DIAGRAM OF GRID CONNECTED PV SYSTEMS Net metering The difference between production-consumption is measured Feed-in tariff The total production of energy is measured 20

21 SIMPLIFIED DIAGRAM OF A TYPICAL GRID CONNECTED INVERTER Self-commutated inverter, with pulse width modulation and line frequency transformer Time Switches S1,S2 cooperate during one half-period - S3,S4 during next half-period Pulse width modulation PWM 21
