Influence of solar tracking error on the performance of a small-scale linear Fresnel reflector

Numerical simulation of a solar water disinfection system based on a small-scale linear Fresnel reflector

“…60), IAM is the incidence angle modi-er (dimensionless) (see ref. 60), and A effi the effective area illuminated on the absorber tube by mirror i in m 2 . Q SSLFR_loss can be calculated by means of the correlation proposed by: 61 q loss = (0.0212v w − 0.6049)(T t − T amb ) + 0.0135q i + 0.0072(T t − T amb ) 2 − 1.046 × 10 −6 × q i (T t − T amb ) − 9.582 × 10 −8 × q i 2 (5)…”

Performance assessment of a dual‐axis solar tracker for concentrator photovoltaic systems

“…The tracking error is defined as the difference between the tracker's position and the actual position of the sun primarily due to limitations of the actuators and installation errors. Barbon et al 34 investigated the influence of solar tracking error on the performance of a small‐scale linear Fresnel lens. Their results indicate that a tracking error of 0.36° would result in an energy loss of approximately 32% for such systems.…”

Turbo-assisted direct solar air heater for medium temperature industrial processes using Linear Fresnel Collectors. Assessment on daily and yearly basis

“…This suggests that a tracking error arises when d𝜃 𝑇 d𝜏 ⁄ increases, due to loss of focus within the interval of time separating two consecutive tracking angle adjustments. Tracking error in concentrating systems, including LFC applications, has been studied by several authors [103], [104], [105], among others. They point out that power loss increases with tracking angle deviation according to the geometry of the concentrator.…”
