Q.2) Which of the following is True or False statment? 1- The current density of photovoltaic cell ranges from 40 to 50 mA/cm². 2- The efficiency of various types of solar collectors decreasing with increasing temperature. (14 Marks) 3- Flat plate collector is used for low temperature systems. 4- In the parabolic dish concept, the concentrator tracks the sun by rotating about two axis. 5- The complement of zenith angle is solar altitude angle. 6- The limit of water head for the Francis turbines is (30-200) m. 7- The maximum limited head for a Kaplan turbine is 30 m. Page 2 of 3 8- The efficiency of geothermal plant is about 15%. 9- Tidal energy development needs huge capacity and long construction time. 10- A maximum efficiency is obtained in paraboloid dish solar collector. 11- The zenith angle is the angle made by the sun's rays with the normal to a horizontal surface. 12- Solar radiation flux is usually measured with the help of a Pyranometer. 13- The surface azimuth angle is the angle made in the horizontal plane between the horizontal line due south and the projection of the normal to the surface on the horizontal plane. 14- Surface azimuth angle varies from -180° to 180°.
