Arudimentary solar electric generating station (segs) system consists of 2500 heliostats, each of 10 m2, focusing on a central tower. the tower-heliostat system is able to transfer 50% of the incoming solar energy to incoming water, which then boils and is transferred to the turbine. ignore other losses between the heliostats and expansion in the turbine. the plant averages 10 h/day of operation year round, and during that time the incoming sun averages 400 w/m2. ignore losses of insolation due to the heliostats not facing in a normal direction to the sun. before entering the tower, the water is compressed to 20 mpa. in the tower it is then heated to 700°c. the superheated steam is then expanded through the turbine using a basic rankine cycle, and condensed at 33°c. assume that the actual efficiency achieved by this cycle is 85% of the ideal efficiency. the generator is 98% efficient. what is the annual electric output in kwh/year?
