RenewableEnergyResources in Oman A Concentrating Solar Power plant should be located in the desert not too far from the coast and sufficient main grid. Water is needed for cooling and for desalination as well as for cleaning of panels. Another important aspects is to consider the delivery of the desalinated water which need to be piped. The SOLAR TRES plant under development in Spain is interesting forOman. It is a system with central receiver (tower) and heat storage in molten salt with a cold and hot tank. The storage is for 15 hours of operation and the system can also be supplemented with a gas boiler. See Fig. 5.8. Fig. 5.8 The SOLAR TRES concentrating Solar Power plant under development in Spain.

RenewableEnergyResources in Oman Fig. 5.9 Main data for the SOLAR TRES concentrating Solar Power plant under development in Spain. Fig. 5.10 The SOLAR TRES concentrating Solar Power plant under development in Spain. View of the mirrors. Ref /15/. Applications The typical applications of solar energy systems are illustrated in Fig. 5.11. Off grid PV systems are typically in the range between few W and up to 100 kW. Grid connected PV systems are typically in the range between few kW and up to 10-20 MW. Solar thermal power plants are only relevant where the solar insolation is high. According the Fig. 6.11 solar thermal power is applicable in Oman having a solar insolation of about 2200 kWh/m2 per year. It also appears that solar thermal plants are preferred for large capacity.
