One challenge facing the widespread use of solar energy
is reduced or curtailed energy production when the sun
sets or is blocked by clouds. Thermal energy storage
provides a workable solution to this challenge

For one collector
𝑄 𝑐 =468.105 (kw.hr/day)
Total number of the collectors
N =

N for solar collectors for day = 9040
N for storage = 7032
Q storage = 7032×468.105 = 3291714.36 kw.hr / day.

41. Size and layout of the solar field
The aperture area of one PTC, AC = trough
aperture × trough length = 5.76×12 = 69.12 m2
The total aperture area of the solar field =
NPTC × AC = 16072×69.12 = 1110896.64 m2
The total solar field area = 3.5×1110896.64 =
3888138.24 m2 = 3.888 km2
