In the case of standstill, e.g. stagnation, the collector array is drained via the return pipe and the liquid is collected in the drain back tank. It is not necessary to install a non-return valve in the primary solar loop. The system is refilled using the solar pump.
A collector array of solar cells is integrated in the building fabric and employed to convert the sun's energy into electrical and/or mechanical power and use, or to store the energy for later use, to heat, light or cool a space or provide hot water. Russell H. Plante, in Solar Energy, Photovoltaics, and Domestic Hot Water.., 2014
All indicators can be calculated in a theoretic analysis at the design time of a plant and therefore allow for a more sophisticated and more economic collector array design. Uneven flow distribution in solar collector arrays results in uneven temperature distribution. Absorber pipes with the smallest mass flows reach the highest temperatures.
Thus, a solar collector array can operate at its full output, without defocusing collectors, even when this heat flux exceeds the heat flux consumed by the ORC, or an ORC can operate at full output during a brief period of cloudy weather. The difference is simply enthalpy gain (or loss) in the TES component.
For maximum solar yield align the collectors at an angle of inclination close to the latitude of the site, and within 10° East or West of due South. If the collector array is mounted on a steep roof or a wall, the orientation of the collector array is identical to that of the roof or wall.
The solar system indicated in the various figures of Section 8.4 is composed of a solar collector array, a storage tank, and the necessary controls. A detailed diagram of such a system is shown in Figure 8.12. In the storage tank, seawater flows through a heat exchanger to avoid scaling in the collectors.

Linear Fresnel Collector (LFC) solar thermal technology
Solar linear Fresnel collector systems are called ''Fresnel'' after the great French optical physicist Augustin-Jean Fresnel (Wikipedia, 2019), who in about 1818 discovered that the effect of large lenses can be duplicated using many small lens components.However, he was long preceded by the famous polymath Georges-Louis Leclerc, Comte de Buffon.

UNIT FOUR SOLAR COLLECTORS
array of heliostats with central receiver. One of the most important factors in concentrating collectors is the concentration ratio. It is defined as the ratio of the area of aperture to the area of the receiver. • The higher the concentration ratio, the smaller the area of the receiver the smaller the heat loss by convection or radiation.
